1 CHANGES IN APE VERSION 3.0-6
6 o reorder.phylo() has a new order, "postorder", and a new option
7 index.only = TRUE to return only the vector of indices (the tree
8 is unmodified; see ?reorder.phylo for details).
13 o reorder(, "pruningwise") made R crash if the rows of the edge
14 matrix are in random order.
19 o dist.nodes() is now 6 to 10 times faster.
21 o reorder(, "cladewise") is now faster. The change is not very
22 visible for small trees (n < 1000) but this can be more than
23 1000 faster for big trees (n >= 1e4).
27 CHANGES IN APE VERSION 3.0-5
32 o ace() should better catch errors when SEs cannot be computed.
37 o write.dna(format = "fasta") now conforms more closely to the
38 FASTA standard thanks to François Michonneau.
40 o print.DNAbin() does not print base compositions if there are more
41 than one million nucleotides.
45 CHANGES IN APE VERSION 3.0-4
50 o read.dna() failed to read Phylip files if the first line used
51 tabulations instead of white spaces.
53 o read.dna() failed to read Phylip or Clustal files with less than
54 10 nucleotides. (See other changes in this function below.)
58 o read.dna() now requires at least one space (or tab) between the
59 taxa names and the sequences (whatever the length of taxa
60 names). write.dna() now follows the same rule.
62 o The option 'seq.names' of read.dna has been removed.
64 o The files ape-defunct.R and ape-defunct.Rd, which have not been
65 modified for almost two years, have been removed.
67 o The C code of bionj() has been reworked: it is more stable (by
68 avoiding passing character strings), slightly faster (by about
69 20%), and numerically more accurate.
71 o The C code of fastme.*() has been slightly modified and should
72 be more stable by avoiding passing character strings (the
73 results are identical to the previous versions).
75 o The file src/newick.c has been removed.
79 CHANGES IN APE VERSION 3.0-3
84 o birthdeath() now catches errors and warnings much better so that
85 a result is returned in most cases.
90 o Because of problems with character string manipulation in C, the
91 examples in ?bionj and in ?fastme have been disallowed. In the
92 meantime, these functions might be unstable. This will be solved
97 CHANGES IN APE VERSION 3.0-2
102 o The new function alex (alignment explorator) zooms in a DNA
103 alignment and opens the result in a new window.
108 o compute.brtime() did not completely randomized the order of the
111 o write.nexus() did not work correctly with rooted trees (thanks
112 to Matt Johnson for the fix).
114 o mltt.plot(, backward = FALSE) did not set the x-axis correctly.
116 o A bug was introduced in prop.clades() with ape 3.0. The help page
117 has been clarified relative to the use of the option 'rooted'.
119 o mantel.test() printed a useless warning message.
121 o plot.phylo(, direction = "downward") ignored 'y.lim'.
123 o is.monophyletic() did not work correctly if 'tips' was not stored
126 o prop.part() could make R crash if the first tree had many
129 o njs(), bionjs(), and mvrs() now return an error if 'fs < 1'.
131 o SDM() did not work correctly. The code has also been generally
137 o The DESCRIPTION file has been updated.
139 o The option 'original.data' of write.nexus() has been removed.
141 o The files bionjs.c, mvr.c, mvrs.c, njs.c, triangMtd.c, and
142 triangMtds.c have been improved which should fix some bugs in
143 the corresponding functions.
145 o dist.gene() now coerces input data frame as matrix resulting in
146 much faster calculations (thanks to a suggestion by Markus
151 CHANGES IN APE VERSION 3.0-1
156 o dist.dna() has two new models: "indel" and "indelblock".
158 o bind.tree() now accepts 'position' > 0 when the trees have no
159 banch length permitting to create a node in 'x' when grafting
160 'y' (see ?bind.tree for details).
165 o cophyloplot( , rotate = TRUE) made R hanged after a few clicks.
166 Also the tree is no more plotted twice.
168 o read.GenBank() has been updated to work with EFetch 2.0.
170 o unroot() on trees in "pruningwise" order did not respect this
175 CHANGES IN APE VERSION 3.0
180 o The three functions dyule, dbd, and dbdTime calculate the
181 density probability (i.e., the distribution of the number of
182 species) for the Yule, the constant and the time-dependent
183 birth-beath models, respectively. These probabilities can be
184 conditional on no extinction and/or on a log-scale.
186 o plot.phylo() has a new option 'rotate.tree' to rotate unrooted,
187 fan, or radial trees around the center of the plot.
189 o boot.phylo() and prop.clades() have a new option rooted =
190 FALSE. Note that the behaviour of prop.part() is unchanged.
192 o edgelabels() has a new option 'date' to place labels on edges of
193 chronograms using the time scale (suggestion by Rob Lanfear).
198 o In chronopl(), the code setting the initial dates failed in
199 complicated settings (several dates known within intervals).
200 This has been generally improved and should result in faster
201 and more efficient convergence even in simple settings.
203 o mantel.test() sometimes returned P-values > 1 with the default
206 o extract.clade() sometimes shuffled some tip labels (thanks to
207 Ludovic Mallet and Mahendra Mariadassou for the fix).
209 o clustal() should now find by default the executable under Windows.
214 o The code of yule() has been simplified and is now much faster for
217 o The code of mantel.test() has been adjusted to be consistent
218 with common permutation tests.
220 o The C code of base.freq() has been improved and is now nearly 8
223 o The option 'original.data' of write.nexus() is now deprecated and
224 will be removed in a future release.
226 o The code of is.ultrametric() has been improved and is now 3 times
229 o The code of vcv.phylo() has been improved and is now 10 or 30
230 times faster for 100 or 1000 tips, respectively. Consequently,
231 fitting models with PGLS will be faster overall.
235 CHANGES IN APE VERSION 2.8
240 o Twelve new functions have been written by Andrei-Alin Popescu:
241 additive, ultrametric, is.compatible, arecompatible, mvr, mvrs,
242 njs, bionjs, SDM, treePop, triangMtd, triangMtd*.
244 o A new class "bitsplits" has been created by Andrei-Alin Popescu
245 to code splits (aka, bipartition).
247 o There is a new generic function as.bitsplits with a method to
248 convert from the class "prop.part" to the class "bitsplits".
250 o The new function ltt.coplot plots on the same scales a tree and
251 the derived LTT plot.
253 o ltt.plot() has two new options: backward and tol. It can now
254 handle non-ultrametic trees and its internal coding has been
255 improved. The coordinates of the plot can now be computed with
256 the new function ltt.plot.coords.
261 o prop.part() crashed if some trees had some multichotomies.
265 CHANGES IN APE VERSION 2.7-3
270 o The new function compute.brtime computes and sets branching times.
272 o mantel.test() has a new argument 'alternative' which is
273 "two-sided" by default. Previously, this test was one-tailed
274 with no possibility to change.
276 o ace() can now do REML estimation with continuous characters,
277 giving better estimates of the variance of the Brownian motion
283 o Branch lengths were wrongly updated with bind.tree(, where = <tip>,
284 position = 0). (Thanks to Liam Revell for digging this bug out.)
286 o Simulation of OU process with rTraitCont() did not work correctly.
287 This now uses formula from Gillespie (1996) reduced to a BM
288 process when alpha = 0 to avoid division by zero. The option
289 'linear' has been removed.
291 o Cross-validation in chronopl() did not work when 'age.max' was
294 o consensus(, p = 0.5) could return an incorrect tree if some
295 incompatible splits occur in 50% of the trees (especially with
296 small number of trees).
298 o c() with "multiPhylo" did not work correctly (thanks to Klaus
299 Schliep for the fix).
301 o root() failed in some cases with an outgroup made of several tips.
302 The help page has been clarified a bit.
306 CHANGES IN APE VERSION 2.7-2
311 o There is a new class "evonet" to code evolutionary networks, with
312 a constructor function evonet(), a print() and a plot() methods,
313 and four conversion methods to the classes "phylo", "networx",
314 "network", and "igraph".
316 o The new function rTraitMult does multivariate traits simulation
317 with user-defined models.
319 o plot.phylo() has a new option 'plot = TRUE'. If FALSE, the tree
320 is not plotted but the graphical device is set and the
321 coordinates are saved as usual.
323 o diversity.contrast.test() gains a fourth version of the test with
324 method = "logratio"; the literature citations have been clarified.
326 o add.scale.bar() has two new options, 'lwd' and 'lcol', to modify
327 the aspect of the bar.
329 o boot.phylo() now displays a progress bar by default (can be off
332 o There is a new predict() method for compar.gee().
337 o bionj() made R crash if distances were too large. It now returns
338 an error if at least one distance is greater than 100.
340 o drop.tip() returned a wrong tree if 'tip' was of zero length.
342 o read.nexus.data() failed with URLs.
344 o boot.phylo() returned overestimated support values in the
345 presence of identical or nearly identical sequences.
350 o The data bird.families, bird.orders, cynipids, and woodmouse are
351 now provided as .rda files.

373 o image.DNAbin() did not colour correctly the bases if there were
376 o .compressTipLabel() failed with a list with a single tree.
378 o identify.phylo() returned a wrong answer when the x- and y-scales
381 o write.nexus() failed with lists of trees with compressed labels.
386 o identify.phylo() now returns NULL if the user right- (instead of
387 left-) clicks (an error was returned previously).
389 o read.nexus() should be robust to commands inserted in the TREES
394 CHANGES IN APE VERSION 2.7
399 o There is a new image() method for "DNAbin" objects: it plots DNA
400 alignments in a flexible and efficient way.
402 o Two new functions as.network.phylo and as.igraph.phylo convert
403 trees of class "phylo" into these respective network classes
404 defined in the packages of the same names.
406 o The three new functions clustal, muscle, and tcoffee perform
407 nucleotide sequence alignment by calling the external programs

411 richness.yule.test, and slowinskiguyer.test, implement various
412 tests of diversification shifts using sister-clade comparisons.
414 o base.freq() gains an option 'all' to count all the possible bases
415 including the ambiguous ones (defaults to FALSE).
417 o read.nexus() now writes tree names in the NEXUS file if given a
418 list of trees with names.

441 column was redundant.
445 CHANGES IN APE VERSION 2.6-3
450 o rTraitCont() and rTraitDisc() gains a '...' argument used with
451 user-defined models (suggestion by Gene Hunt).
456 o as.hclust.phylo() now returns an error with unrooted trees.
458 o as.hclust.phylo() failed with trees with node labels (thanks to
459 Jinlong Zhang for pointing this bug out).
461 o read.dna(, "fasta") failed if sequences were not all of the same
464 o plot.phylo() did not recycle values of 'font', 'cex' and
465 'tip.color' correctly when type = "fan" or "radial".
467 o plot.phylo() ignored 'label.offset' when type = "radial", "fan", or
468 "unrooted" with lab4ut = "axial" (the placement of tip labels still
469 needs to be improved with lab4ut = "horizontal").
474 o In drop.fossil() the default tol = 0 has been raised to 1e-8.
476 o The help command ?phylo now points to the man page of read.tree()
477 where this class is described. Similarly, ?matching points to the
478 man page of as.matching().
482 CHANGES IN APE VERSION 2.6-2
487 o Two new functions, pic.ortho and varCompPhylip, implements the
488 orthonormal contrasts of Felsenstein (2008, Am Nat, 171:713). The
489 second function requires Phylip to be installed on the computer.
491 o bd.ext() has a new option conditional = TRUE to use probabilities
492 conditioned on no extinction for the taxonomic data.
497 o write.tree() failed to output correctly tree names.
499 o dist.nodes() returned duplicated column(s) with unrooted and/or
500 multichotomous trees.
502 o mcmc.popsize() terminated unexpectedly if the progress bar was
505 o prop.part(x) made R frozen if 'x' is of class "multiPhylo".

509 o drop.tip() shuffled tip labels with subtree = TRUE or trim.internal
512 o Objects returned by as.hclust.phylo() failed when analysed with
513 cutree() or rect.hclust().

516 Matasci and Jeremy Beaulieu for the fix).
518 o ace(type = "discrete") has been improved thanks to Naim Marasci and
523 CHANGES IN APE VERSION 2.6-1
528 o The new function speciesTree calculates the species tree from a set
529 of gene trees. Several methods are available including maximum tree
530 and shallowest divergence tree.

537 o as.list.DNAbin() did not work correctly with vectors.
539 o as.hclust.phylo() failed with trees with node labels (thanks to
540 Filipe Vieira for the fix).
544 CHANGES IN APE VERSION 2.6
549 o The new functions rlineage and rbdtree simulate phylogenies under
550 any user-defined time-dependent speciation-extinction model. They
551 use continuous time algorithms.
553 o The new function drop.fossil removes the extinct species from a
556 o The new function bd.time fits a user-defined time-dependent
557 birth-death model. It is a generalization of yule.time() taking

563 o The new function Ftab computes the contingency table of base
564 frequencies from a pair of sequences.

572 control the aspect of thermometers: horiz = TRUE, width = NULL,
575 o compar.gee() has been improved with the new option 'corStruct' as an
576 alternative to 'phy' to specify the correlation structure, and
577 calculation of the QIC (Pan 2001, Biometrics). The display of the
578 results has also been improved.
580 o read.GenBank() has a new option 'gene.names' to return the name of
581 the gene (FALSE by default).
586 o extract.clade() sometimes shuffled the tip labels.
588 o plot.phylo(type = "unrooted") did not force asp = 1 (thanks to Klaus
591 o dist.dna(model = "logdet") used to divide distances by 4. The
592 documentation has been clarified on the formulae used.
597 o rTraitCont(model = "OU") has an option 'linear = TRUE' to possibly
598 change the parameterisation (see ?rTraitCont for details).
600 o pic() now returns a vector with the node labels of the tree (if

604 to contributions by Klaus Schliep.
608 CHANGES IN APE VERSION 2.5-3
613 o The new function mixedFontLabel helps to make labels with bits of
614 text to be plotted in different fonts.
616 o There are now replacement operators for [, [[, and $ for the class
617 "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They possibly
618 check that the tip labels are the same in all trees.
620 o Objects of class "multiPhylo" can be built with c(): there are
621 methods for the classes "phylo" and "multiPhylo".
623 o The internal functions .compressTipLabel and .uncompressTipLabel are
629 o bind.tree(x, y, where, position = 0) did not work correctly if 'y'

689 o drop.tip(), extract.clade(), root(), and bind.tree() now have an
690 'interactive' option to make the operation on a plotted tree.
692 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
693 association links; they are recycled like 'col' (which wasn't before).
698 o rTraitDisc() did not use its 'freq' argument correctly (it was
699 multiplied with the rate matrix column-wise instead of row-wise).
701 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
702 with NA values. Nothing is drawn now like with 'text' or 'pch'.
703 The same bug occurred with the 'pie' option.
705 o A bug was fixed in compar.ou() and the help page was clarified.
707 o bind.tree() has been rewritten fixing several bugs and making it
710 o plot.phylo(type = "p") sometimes failed to colour correctly the

714 in the correct direction though the tip labels were displayed
720 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
721 the sequences are correctly stored (in a list for c, in a matrix
722 for the two other functions).
726 CHANGES IN APE VERSION 2.5
731 o The new function parafit by Pierre Legendre tests for the
732 coevolution between hosts and parasites. It has a companion
733 function, pcoa, that does principal coordinate decomposition.
734 The latter has a biplot method.
736 o The new function lmorigin by Pierre Legendre performs multiple
737 regression through the origin with testing by permutation.
739 o The new functions rTraitCont and rTraitDisc simulate continuous and
740 discrete traits under a wide range of evolutionary models.
742 o The new function delta.plot does a delta plot following Holland et
743 al. (2002, Mol. Biol. Evol. 12:2051).
745 o The new function edges draws additional branches between any nodes
746 and/or tips on a plotted tree.
748 o The new function fancyarrows enhances arrows from graphics with
749 triangle and harpoon heads; it can be called from edges().
751 o add.scale.bar() has a new option 'ask' to draw interactively.
753 o The branch length score replaces the geodesic distance in dist.topo.
755 o Three new data sets are included: the gopher-lice data (gopher.D),
756 SO2 air pollution in 41 US cities (lmorigin.ex1, from Sokal &
757 Rohlf 1995), and some host-parasite specificity data
758 (lmorigin.ex2, from Legendre & Desdevises 2009).
763 o add.scale.bar() drew the bar outside the plotting region with the
764 default options with unrooted or radial trees.
766 o dist.topo() made R stuck when the trees had different sizes (thanks
767 to Otto Cordero for the fix).

777 CHANGES IN APE VERSION 2.4-1
782 o rtree() and rcoal() now accept a numeric vector for the 'br'
785 o vcv() is a new generic function with methods for the classes "phylo"
786 and "corPhyl" so that it is possible to calculate the var-cov matrix
787 for "transformation models". vcv.phylo() can still be used for trees
788 of class "phylo"; its argument 'cor' has been renamed 'corr'.
793 o bind.tree() failed when 'y' had no root edge.
795 o read.nexus() shuffled tip labels when the trees have no branch
796 lengths and there is a TRANSLATE block.
798 o read.nexus() does not try to translate node labels if there is a
799 translation table in the NEXUS file. See ?read.nexus for a
800 clarification on this behaviour.
802 o plot.multiPhylo() crashed R when plotting a list of trees with
803 compressed tip labels.
805 o write.nexus() did not translate the taxa names when asked for.
807 o plot.phylo(type = "fan") did not rotate the tip labels correctly
808 when the tree has branch lengths.

811 negative (which resulted in an error).
813 o nj() crashed with NA/NaN in the distance matrix: an error in now
818 CHANGES IN APE VERSION 2.4
823 o base.freq() has a new option 'freq' to return the counts; the
824 default is still to return the proportions.
829 o seg.sites() did not handle ambiguous nucleotides correctly: they
832 o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
833 the tree: the argument is now ignored.
835 o add.scale.bar() failed when 'x' and 'y' were given (thanks to Janet
841 o Trying to plot a tree with a single tip now returns NULL with a
842 warning (it returned an error previously).
844 o The way lines representing nodes are coloured in phylograms has
845 been modified (as well as their widths and types) following some
846 users' request; this is only for dichotomous nodes.
848 o The argument 'adj' in [node][tip][edge]labels() now works when
849 using 'pie' or 'thermo'.
851 o A more informative message error is now returned by dist.dna() when
852 'model' is badly specified (partial matching of this argument is
855 o Deprecated functions are now listed in a help page: see
856 help("ape-defunct") with the quotes.
861 o The functions heterozygosity, nuc.div, theta.h, theta.k and
862 theta.s have been moved from ape to pegas.

898 o all.equal.phylo() did not compare unrooted trees correctly.
900 o dist.topo(... method = "PH85") did not treat unrooted trees
901 correctly (thanks to Tim Wallstrom for the fix).
903 o root() sometimes failed to test for the monophyly of the
906 o extract.clade() sometimes included too many edges.
908 o vcv.phylo() did not work correctly when the tree is in
911 o nj() did not handle correctly distance matrices with many 0's.
912 The code has also been significantly improved: 7, 70, 160 times
913 faster with n = 100, 500, 1000, respectively.
917 CHANGES IN APE VERSION 2.3-1
922 o The new function is.monophyletic tests the monophyly of a group.
924 o There is now a c() method for lists of class "DNAbin".
926 o yule.cov() now fits the null model, and its help page has been
927 corrected with respect to this change.
929 o drop.tip() has a new option 'rooted' to force (or not) a tree
930 to be treated as (un)rooted.
935 o dist.gene() failed on most occasions with the default

944 o A small bug was fixed in CDAM.global().
946 o ace() failed with large data sets. Thanks to Rich FitzJohn for
947 the fix. With other improvements, this function is now about 6
950 o write.tree() failed with objects of class "multiPhylo".
952 o drop.tip(, subtree = TRUE) sometimes shuffled tip labels.
957 o [.multiPhylo and [.DNAbin now respect the original class.
959 o Instances of the form class(phy) == "phylo" have been replaced
960 by inherits(phy, "phylo").

987 handle individual tree names.
989 o plot.phylo() has a new argument 'edge.lty' that specifies the
990 types of lines used for the edges (plain, dotted, dashed, ...)
992 o phymltest() has been updated to work with PhyML 3.0.1.
997 o drop.tip() shuffled tip labels in some cases.
999 o drop.tip() did not handle node.label correctly.
1001 o is.ultrametric() now checks the ordering of the edge matrix.

1004 ancestral states (thanks to Dan Rabosky for solving this long
1010 o The data set xenarthra has been removed.
1014 CHANGES IN APE VERSION 2.2-4
1018 o The bug fix in read.nexus() in version 2.2-3 was wrong: this is
1019 now fixed. (Thanks to Peter Wragg for the fix!)
1021 o A warning message occurred for no reason with ace(method="GLS").
1026 o There is now a general help page displayed with '?ape'.

1050 multiple lines with different numbers of lines and/or with
1051 comments inserted within the trees).
1053 o ltt.plot(), ltt.lines(), and mltt.plot() did not count correctly
1054 the number of lineages with non-binary trees.
1059 o ape has now a namespace.
1061 o drop.tip() has been improved: it should be much faster and work
1062 better in some cases (e.g., see the example in ?zoom).
1066 CHANGES IN APE VERSION 2.2-2
1071 o dist.gene() has been substantially improved and gains an option
1072 'pairwise.deletion'.
1074 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
1080 o prop.part() failed with a single tree with the default option
1081 'check.labels = TRUE'.
1083 o summary.DNAbin() failed to display correctly the summary of
1084 sequence lengths with lists of sequences of 10,000 bases or more
1085 (because summary.default uses 4 significant digits by default).
1087 o read.nexus() failed to read a file with a single tree with line
1088 breaks in the Newick string.
1090 o del.gaps() returned a list of empty sequences when there were no
1096 o phymltest() has been updated for PhyML 3.0 and gains an option
1097 'append', whereas the option 'path2exec' has been removed.
1099 o rbind.DNAbin() and cbind.DNAbin() now accept a single matrix
1100 which is returned unchanged (instead of an error).
1102 o The data sets bird.orders and bird.families are now stored as
1103 Newick strings; i.e., the command data(bird.orders) calls
1108 CHANGES IN APE VERSION 2.2-1
1113 o The new function makeLabel() helps to modify labels of trees,
1114 lists of trees, or DNA sequences, with several utilities to
1115 truncate and/or make them unique, substituting some
1116 characters, and so on.
1118 o The new function del.gaps() removes insertion gaps ("-") in a
1119 set of DNA sequences.
1121 o read.dna() can now read Clustal files (*.aln).
1126 o root() failed with 'resolve.root = TRUE' when the root was
1127 already the specified root.
1129 o Several bugs were fixed in mlphylo().
1131 o collapsed.singles() did not propagate the 'Nnode' and
1132 'node.labels' elements (thanks to Elizabeth Purdom for the fix).
1134 o read.nexus() failed to remove correctly the comments within
1137 o read.nexus() failed to read a file with a single tree and no
1138 translation of tip labels.

1159 CHANGES IN APE VERSION 2.2
1164 o Four new functions have been written by Damien de Vienne for the
1165 graphical exploration of large trees (cophyloplot, subtrees,
1166 subtreeplot), and to return the graphical coordinates of tree
1169 o The new functions corPagel and corBlomberg implement the Pagel's
1170 "lambda" and Blomberg et al.'s "ACDC" correlation structures.
1172 o chronopl() has been improved and gains several options: see its
1173 help page for details.
1175 o boot.phylo() has now an option 'trees' to possibly return the
1176 bootstraped trees (the default is FALSE).
1178 o prop.part() has been improved and should now be faster in all
1184 o read.dna() failed if "?" occurred in the first 10 sites of the
1187 o The x/y aspect of the plot is now respected when plotting a
1188 circular tree (type = "r" or "f").
1190 o Drawing the tip labels sometimes failed when plotting circular
1193 o zoom() failed when tip labels were used instead of their numbers
1194 (thanks to Yan Wong for the fix).
1196 o drop.tip() failed with some trees (fixed by Yan Wong).
1198 o seg.sites() failed with a list.
1200 o consensus() failed in some cases. The function has been improved

1205 CHANGES IN APE VERSION 2.1-3
1210 o A bug in read.nexus() made the Windows R-GUI crash.
1212 o An error was fixed in the computation of ancestral character
1213 states by generalized least squares in ace().

1230 o root() gains the options 'node' and 'resolve.root'
1231 (FALSE by default) as well as its code being improved.
1233 o mltt.plot() has now an option 'log' used in the same way
1234 than in plot.default().
1239 o mltt.plot() failed to display the legend with an unnamed
1242 o nodelabels() with pies now correcly uses the argument
1243 'cex' to draw symbols of different sizes (which has
1244 worked already for thermometers).
1246 o read.nexus() generally failed to read very big files.
1251 o The argument 'family' of compar.gee() can now be a function
1252 as well as a character string.
1254 o read.tree() and read.nexus() now return an unnamed list if
1255 'tree.names = NULL'.
1257 o read.nexus() now returns a modified object of class "multiPhylo"
1258 when there is a TRANSLATE block in the NEXUS file: the individual
1259 trees have no 'tip.label' vector, but the list has a 'TipLabel'
1260 attribute. The new methods '$' and '[[' set these elements
1261 correctly when extracting trees.
1265 CHANGES IN APE VERSION 2.1-1
1270 o The new function rmtree generates lists of random trees.
1272 o rcoal() now generates a genuine coalescent tree by default
1273 (thanks to Vladimir Minin for the code).

1279 pairwise.deletion = FALSE.
1284 o The internal codes of bionj(), fastme.bal(), and fastme.ols()
1285 have been improved so that they are stabler and faster.
1287 o R packages used by ape are now loaded silently; lattice and gee

1292 CHANGES IN APE VERSION 2.1
1297 o The new function identify.phylo identifies clades on a plotted
1298 tree using the mouse.

1301 "multiPhylo") with "[" while keeping its class correct.
1303 o The new function as.DNAbin.alignment converts DNA sequences
1304 stored in the "alignment" format of the package seqinr into
1305 an object of class "DNAbin".
1307 o The new function weight.taxo2 helps to build similarity matrices
1308 given two taxonomic levels (usually called by other functions).
1310 o write.tree() can now take a list of trees (class "multiPhylo")
1311 as its main argument.
1313 o plot.correlogram() and plot.correlogramList() have been
1314 improved, and gain several options (see the help page for
1315 details). A legend is now plotted by default.
1320 o dist.dna() returned some incorrect values with `model = "JC69"'
1321 and `pairwise.deletion = TRUE'. This affected only the
1322 distances involving sequences with missing values. (Thanks
1323 to Bruno Toupance for digging this bug out.)
1325 o write.tree() failed with some trees: this is fixed by removing
1326 the `multi.line' option (trees are now always printed on a
1329 o read.nexus() did not correctly detect trees with multiple root
1330 edges (see OTHER CHANGES).
1335 o The code of mlphylo() has been almost entirely rewritten, and
1336 should be much stabler. The options have been also greatly
1337 simplified (see ?mlphylo and ?DNAmodel for details).
1339 o The internal function nTips has been renamed klastorin_nTips.
1341 o The code of is.ultrametric() contained redundancies and has
1344 o The code of Moran.I() and of correlogram.formula() have been
1347 o read.tree() and read.nexus() now return an error when trying to
1348 read a tree with multiple root edges (see BUG FIXES). The
1349 correction applied in previous version did not work in all
1352 o The class c("multi.tree", "phylo") has been renamed
1358 o There is now a vignette in ape: see vignette("MoranI", "ape").
1361 DEPRECATED & DEFUNCT
1363 o as.matching() and as.phylo.matching() do not support branch
1366 o correlogram.phylo() and discrete.dist() have been removed.
1370 CHANGES IN APE VERSION 2.0-2
1375 o The new function matexpo computes the exponential of a square
1378 o The new function unique.multi.tree removes duplicate trees from
1381 o yule() has a new option `use.root.edge = FALSE' that specifies
1382 to ignore, by default, the root edge of the tree if it exists.
1387 o which.edge() failed when the index of a single terminal edge was
1390 o In diversi.time(), the values returned for model C were
1393 o A bug was fixed in yule() that affected the calculation of the
1394 likelihood in the presence of ties in the branching times.
1396 o There was a bug in the C function mat_expo4x4 affecting the
1397 calculations of the transition probabilities for models HKY and
1400 o A small bug was fixed in as.matrix.DNAbin (thanks to James
1403 o rtree() did not `shuffle' the tip labels by default, so only a
1404 limited number of labelled topologies could be generated.
1408 CHANGES IN APE VERSION 2.0-1
1413 o The three new functions bionj, fastme.ols, and fastme.bal
1414 perform phylogeny estimation by the BIONJ and fastME methods in
1415 OLS and balanced versions. This is a port to R of previous
1416 previous programs done by Vincent Lefort.
1418 o The new function chronoMPL performs molecular dating with the
1419 mean path lengths method of Britton et al. (2002, Mol. Phyl.
1422 o The new function rotate, contributed by Christoph Heibl, swaps
1423 two clades connected to the same node. It works also with
1424 multichotomous nodes.
1426 o The new `method' as.matrix.DNAbin() may be used to convert
1427 easily DNA sequences stored in a list into a matrix while
1428 keeping the names and the class.
1433 o chronopl() failed when some branch lengths were equal to zero:
1434 an error message is now returned.
1436 o di2multi() failed when there was a series of consecutive edges
1441 CHANGES IN APE VERSION 1.10-2
1446 o plot.phylo() can now plot circular trees: the option is type =
1447 "fan" or type = "f" (to avoid the ambiguity with type = "c").
1449 o prop.part() has a new option `check.labels = FALSE' which allows
1450 to considerably speed-up the calculations of bipartitions. As a
1451 consequence, calculations of bootstrap values with boot.phylo()
1452 should be much faster.
1457 o read.GenBank() did not return correctly the list of species as
1458 from ape 1.10: this is fixed in this version
1460 o Applying as.phylo() on a tree of class "phylo" failed: the
1461 object is now returned unchanged.
1465 CHANGES IN APE VERSION 1.10-1
1470 o The three new functions Ntip, Nnode, and Nedge return, for a
1471 given tree, the number of tips, nodes, or edges, respectively.
1476 o read.nexus() did not set correctly the class of the returned
1477 object when reading multiple trees.
1479 o mllt.plot() failed with objects of class c("multi.tree",
1482 o unroot() did not work correctly in most cases.
1484 o reorder.phylo() made R freeze in some occasions.
1486 o Plotting a tree in pruningwise order failed.
1488 o When plotting an unrooted tree, the tip labels where not all
1489 correctly positioned if the option `cex' was used.
1493 CHANGES IN APE VERSION 1.10
1498 o Five new `method' functions have been introduced to manipulate
1499 DNA sequences in binary format (see below).
1501 o Three new functions have been introduced to convert between the
1502 new binary and the character formats.
1504 o The new function as.alignment converts DNA sequences stored as
1505 single characters into the class "alignment" used by the package
1508 o read.dna() and read.GenBank() have a new argument `as.character'
1509 controlling whether the sequences are returned in binary format
1515 o root() failed when the tree had node labels: this is fixed.
1517 o plot.phylo() did not correctly set the limits on the y-axis with
1518 the default setting: this is fixed.
1520 o dist.dna() returned a wrong result for the LogDet, paralinear,
1521 and BH87 models with `pairwise.deletion = TRUE'.
1526 o DNA sequences are now internally stored in a binary format. See
1527 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1528 details. Most functions analyzing DNA functions have been
1529 modified accordingly and are now much faster (dist.dna is now
1530 ca. 60 times faster).
1534 CHANGES IN APE VERSION 1.9-4
1539 o A bug was fixed in edgelabels().
1541 o as.phylo.hclust() did not work correctly when the object of
1542 class "hclust" has its labels set to NULL: the returned tree has
1543 now its tip labels set to "1", "2", ...
1545 o consensus could fail if some tip labels are a subset of others
1546 (e.g., "a" and "a_1"): this is now fixed.
1548 o mlphylo() failed in most cases if some branch lengths of the
1549 initial tree were greater than one: an error message is now
1552 o mlphylo() failed in most cases when estimating the proportion of
1553 invariants: this is fixed.
1557 CHANGES IN APE VERSION 1.9-3
1562 o The new function edgelabels adds labels on the edge of the tree
1563 in the same way than nodelabels or tiplabels.
1568 o multi2di() did not handle correctly branch lengths with the
1569 default option `random = TRUE': this is now fixed.
1571 o A bug was fixed in nuc.div() when using pairwise deletions.
1573 o A bug occurred in the analysis of bipartitions with large
1574 numbers of large trees, with consequences on prop.part,
1575 prop.clades, and boot.phylo.
1577 o The calculation of the Billera-Holmes-Vogtmann distance in
1578 dist.topo was wrong: this has been fixed.
1582 CHANGES IN APE VERSION 1.9-2
1587 o The new function ladderize reorganizes the internal structure of
1588 a tree to plot them left- or right-ladderized.
1590 o The new function dist.nodes computes the patristic distances
1591 between all nodes, internal and terminal, of a tree. It replaces
1592 the option `full = TRUE' of cophenetic.phylo (see below).
1597 o A bug was fixed in old2new.phylo().
1599 o Some bugs were fixed in chronopl().
1601 o The edge colours were not correctly displayed by plot.phylo
1602 (thank you to Li-San Wang for the fix).
1604 o cophenetic.phylo() failed with multichotomous trees: this is
1610 o read.dna() now returns the sequences in a matrix if they are
1611 aligned (interleaved or sequential format). Sequences in FASTA
1612 format are still returned in a list.
1614 o The option `full' of cophenetic.phylo() has been removed because
1615 it could not be used from the generic.
1618 DEPRECATED & DEFUNCT
1620 o rotate() has been removed; this function did not work correctly
1625 CHANGES IN APE VERSION 1.9-1
1630 o Trees with a single tip were not read correctly in R as the
1631 element `Nnode' was not set: this is fixed.
1633 o unroot() did not set correctly the number of nodes of the
1634 unrooted tree in most cases.
1636 o read.GenBank() failed when fetching very long sequences,
1637 particularly of the BX-series.
1639 o A bug was introduced in read.tree() with ape 1.9: it has been
1644 CHANGES IN APE VERSION 1.9
1649 o There are two new print `methods' for trees of class "phylo" and
1650 lists of trees of class "multi.tree", so that they are now
1651 displayed in a compact and informative way.
1653 o There are two new functions, old2new.phylo and new2old.phylo,
1654 for converting between the old and new coding of the class
1657 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1658 LogDet ("logdet"), and paralinear ("paralin").
1660 o compute.brlen() has been extended: several methods are now
1661 available to compute branch lengths.
1663 o write.dna() can now handle matrices as well as lists.
1668 o cophenetic.phylo() sometimes returned a wrong result with
1669 multichotomous trees: this is fixed.
1671 o rotate() failed when a single tip was specified: the tree is now
1674 o ace() did not return the correct index matrix with custom
1675 models: this is fixed.
1677 o multi2di() did not work correctly when resolving multichotomies
1678 randomly: the topology was always the same, only the arrangement
1679 of clades was randomized: this is fixed. This function now
1680 accepts trees with no branch lengths.
1682 o The output of diversi.gof() was blurred by useless prints when a
1683 user distribution was specified. This has been corrected, and
1684 the help page of this function has been expanded.
1689 o The internal structure of the class "phylo" has been changed:
1690 see the document "Definition of Formats for Coding Phylogenetic
1691 Trees in R" for the details. In addition, the code of most
1692 functions has been improved.
1694 o Several functions have been improved by replacing some R codes
1695 by C codes: pic, plot.phylo, and reorder.phylo.
1697 o There is now a citation information: see citation("ape") in R.
1699 o write.tree() now does not add extra 0's to branch lengths so
1700 that 1.23 is printed "1.23" by default, not "1.2300000000".
1702 o The syntax of bind.tree() has been simplified. This function now
1703 accepts trees with no branch lengths, and handles correctly node
1706 o The option `as.numeric' of mrca() has been removed.
1708 o The unused options `format' and `rooted' of read.tree() have
1711 o The unused option `format' of write.tree() has been removed.
1713 o The use of node.depth() has been simplified.
1717 CHANGES IN APE VERSION 1.8-5
1722 o Two new functions read.nexus.data() and write.nexus.data(),
1723 contributed by Johan Nylander, allow to read and write molecular
1724 sequences in NEXUS files.
1726 o The new function reorder.phylo() reorders the internal structure
1727 of a tree of class "phylo". It is used as the generic, e.g.,
1730 o read.tree() and read.nexus() can now read trees with a single
1733 o The new data set `cynipids' supplies a set of protein sequences
1739 o The code of all.equal.phylo() has been completely rewritten
1740 (thanks to Benoît Durand) which fixes several bugs.
1742 o read.tree() and read.nexus() now checks the labels of the tree
1743 to remove or substitute any characters that are illegal in the
1744 Newick format (parentheses, etc.)
1746 o A negative P-value could be returned by mantel.test(): this is
1751 CHANGES IN APE VERSION 1.8-4
1756 o The new function sh.test() computes the Shimodaira-
1759 o The new function collapse.singles() removes the nodes with a
1760 single descendant from a tree.
1762 o plot.phylo() has a new argument `tip.color' to specify the
1763 colours of the tips.
1765 o mlphylo() has now an option `quiet' to control the display of
1766 the progress of the analysis (the default is FALSE).
1771 o read.dna() did not read correctly sequences in sequential format
1772 with leading alignment gaps "-": this is fixed.
1774 o ace() returned a list with no class so that the generic
1775 functions (anova, logLik, ...) could not be used directly. This
1776 is fixed as ace() now returns an object of class "ace".
1778 o anova.ace() had a small bug when computing the number of degrees
1779 of freedom: this is fixed.
1781 o mlphylo() did not work when the sequences were in a matrix or
1782 a data frame: this is fixed.
1784 o rtree() did not work correctly when trying to simulate an
1785 unrooted tree with two tips: an error message is now issued.
1790 o The algorithm of rtree() has been changed: it is now about 40,
1791 100, and 130 times faster for 10, 100, and 1000 tips,
1796 CHANGES IN APE VERSION 1.8-3
1801 o There are four new `method' functions to be used with the
1802 results of ace(): logLik(), deviance(), AIC(), and anova().
1804 o The plot method of phymltest has two new arguments: `main' to
1805 change the title, and `col' to control the colour of the
1806 segments showing the AIC values.
1808 o ace() has a new argument `ip' that gives the initial values used
1809 in the ML estimation with discrete characters (see the examples
1810 in ?ace). This function now returns a matrix giving the indices
1811 of the estimated rates when analysing discrete characters.
1813 o nodelabels() and tiplabels() have a new argument `pie' to
1814 represent proportions, with any number of categories, as
1815 piecharts. The use of the option `thermo' has been improved:
1816 there is now no limitation on the number of categories.
1821 o mlphylo() did not work with more than two partitions: this is
1824 o root() failed if the proposed outgroup was already an outgroup
1825 in the tree: this is fixed.
1827 o The `col' argument in nodelabels() and tiplabels() was not
1828 correctly passed when `text' was used: this is fixed.
1830 o Two bugs were fixed in mlphylo(): parameters were not always
1831 correctly output, and the estimation failed in some cases.
1833 o plot.phylo() was stuck when given a tree with a single tip: this
1834 is fixed and a message error is now returned.
1836 o An error was corrected in the help page of gammaStat regarding
1837 the calculation of P-values.
1839 o Using gls() could crash R when the number of species in the tree
1840 and in the variables were different: this is fixed.
1844 CHANGES IN APE VERSION 1.8-2
1849 o The new function mlphylo() fits a phylogenetic tree by maximum
1850 likelihood from DNA sequences. Its companion function DNAmodel()
1851 is used to define the substitution model which may include
1852 partitioning. There are methods for logLik(), deviance(), and
1853 AIC(), and the summary() method has been extended to display in
1854 a friendly way the results of this model fitting. Currently, the
1855 functionality is limited to estimating the substitution and
1856 associated parameters and computing the likelihood.
1858 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1859 tests for single effects in GEE-based comparative method. A
1860 warning message is printed if there is not enough degrees of
1866 o An error message was sometimes issued by plot.multi.tree(),
1867 though with no consequence.
1871 CHANGES IN APE VERSION 1.8-1
1876 o There is a new plot method for lists of trees (objects of class
1877 "multi.tree"): it calls plot.phylo() internally and is
1878 documented on the same help page.
1883 o A bug was fixed in the C code that analyzes bipartitions: this
1884 has impact on several functions like prop.part, prop.clades,
1885 boot.phylo, or consensus.
1887 o root() did not work correctly when the specified outgroup had
1888 more than one element: this is fixed.
1890 o dist.dna() sometimes returned a warning inappropriately: this
1893 o If the distance object given to nj() had no rownames, nj()
1894 returned a tree with no tip labels: it now returns tips labelled
1895 "1", "2", ..., corresponding to the row numbers.
1900 o nj() has been slightly changed so that tips with a zero distance
1901 are first aggregated with zero-lengthed branches; the usual NJ
1902 procedure is then performed on a distance matrix without 0's.
1906 CHANGES IN APE VERSION 1.8
1911 o The new function chronopl() estimates dates using the penalized
1912 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1914 o The new function consensus() calculates the consensus tree of a
1917 o The new function evolve.phylo() simulates the evolution of
1918 continuous characters along a phylogeny under a Brownian model.
1920 o The new plot method for objects of class "ancestral" displays a
1921 tree together with ancestral values, as returned by the above
1924 o The new function as.phylo.formula() returns a phylogeny from a
1925 set of nested taxonomic variables given as a formula.
1927 o The new function read.caic() reads trees in CAIC format.
1929 o The new function tiplabels() allows to add labels to the tips
1930 of a tree using text or plotting symbols in a flexible way.
1932 o The new function unroot() unroots a phylogeny.
1934 o multi2di() has a new option, `random', which specifies whether
1935 to resolve the multichotomies randomly (the default) or not.
1937 o prop.part() now returns an object of class "prop.part" for which
1938 there are print (to display a partition in a more friendly way)
1939 and summary (to extract the numbers) methods.
1941 o plot.phylo() has a new option, `show.tip.label', specifying
1942 whether to print the labels of the tips. The default is TRUE.
1944 o The code of nj() has been replaced by a faster C code: it is now
1945 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1948 o write.nexus() now writes whether a tree is rooted or not.
1953 o Two bugs have been fixed in root(): unrooted trees are now
1954 handled corretly, and node labels are now output normally.
1956 o A bug was fixed in phymltest(): the executable couldn't be found
1959 o Three bug have been fixed in ace(): computing the likelihood of
1960 ancestral states of discrete characters failed, custom models
1961 did not work, and the function failed with a null gradient (a
1962 warning message is now returned; this latter bug was also
1963 present in yule.cov() as well and is now fixed).
1965 o pic() hanged out when missing data were present: a message error
1968 o A small bug was fixed in dist.dna() where the gamma correction
1969 was not always correctly dispatched.
1971 o plot.phylo() plotted correctly the root edge only when the tree
1972 was plotted rightwards: this works now for all directions.
1977 o dist.taxo() has been renamed as weight.taxo().
1979 o dist.phylo() has been replaced by the method cophenetic.phylo().
1981 o Various error and warning messages have been improved.
1985 CHANGES IN APE VERSION 1.7
1988 o The new function ace() estimates ancestral character states for
1989 continuous characters (with ML, GLS, and contrasts methods), and
1990 discrete characters (with ML only) for any number of states.
1992 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1993 of directional evolution for continuous characters. The user
1994 specifies the node(s) of the tree where the character optimum
1997 o The new function is.rooted() tests whether a tree (of class
2000 o The new function rcoal() generates random ultrametric trees with
2001 the possibility to specify the function that generates the
2002 inter-nodes distances.
2004 o The new function mrca() gives for all pairs of tips in a tree
2005 (and optionally nodes too) the most recent common ancestor.
2007 o nodelabels() has a new option `thermo' to plot proportions (up
2008 to three classes) on the nodes of a tree.
2010 o rtree() has been improved: it can now generate rooted or
2011 unrooted trees, and the mathematical function that generates the
2012 branch lengths may be specified by the user. The tip labels may
2013 be given directly in the call to rtree. The limit cases (n = 2,
2014 3) are now handled correctly.
2016 o dist.topo() has a new argument `method' with two choices: "PH85"
2017 for Penny and Henny's method (already available before and now
2018 the default), and "BHV01" for the geometric distance by Billera
2019 et al. (2001, Adv. Appl. Math. 27:733).
2021 o write.tree() has a new option, `digits', which specifies the
2022 number of digits to be printed in the Newick tree. By default
2023 digits = 10. The numbers are now always printed in decimal form
2024 (i.e., 1.0e-1 is now avoided).
2026 o dist.dna() can now compute the raw distances between pairs of
2027 DNA sequences by specifying model = "raw".
2029 o dist.phylo() has a new option `full' to possibly compute the
2030 distances among all tips and nodes of the tree. The default if
2036 o Several bugs were fixed in all.equal.phylo().
2038 o dist.dna() did not handle correctly gaps ("-") in alignments:
2039 they are now considered as missing data.
2041 o rotate() did not work if the tips were not ordered: this is
2044 o mantel.test() returned NA in some special cases: this is fixed
2045 and the function has been improved and is now faster.
2047 o A bug was fixed in diversi.gof() where the calculation of A² was
2050 o cherry() did not work correctly under some OSs (mainly Linux):
2053 o is.binary.tree() has been modified so that it works with both
2054 rooted and unrooted trees.
2056 o The documentation of theta.s() was not correct: this has been
2059 o plot.mst() did not work correctly: this is fixed.
2063 CHANGES IN APE VERSION 1.6
2068 o The new function dist.topo() computes the topological distances
2071 o The new function boot.phylo() performs a bootstrap analysis on
2072 phylogeny estimation.
2074 o The new functions prop.part() and prop.clades() analyse
2075 bipartitions from a series of trees.
2080 o read.GenBank() now uses the EFetch utility of NCBI instead of
2081 the usual Web interface: it is now much faster (e.g., 12 times
2082 faster to retrieve 8 sequences, 37 times for 60 sequences).
2087 o Several bugs were fixed in read.dna().
2089 o Several bugs were fixed in diversi.time().
2091 o is.binary.tree() did not work correctly if the tree has no edge
2092 lengths: this is fixed.
2094 o drop.tip() did not correctly propagated the `node.label' of a
2095 tree: this is fixed.
2099 CHANGES IN APE VERSION 1.5
2104 o Two new functions, as.matching.phylo() and as.phylo.matching(),
2105 convert objects between the classes "phylo" and "matching". The
2106 latter implements the representation of binary trees introduced by
2107 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
2108 as.matching() has been introduced as well.
2110 o Two new functions, multi2di() and di2multi(), allow to resolve
2111 and collapse multichotomies with branches of length zero.
2113 o The new function nuc.div() computes the nucleotide diversity
2114 from a sample a DNA sequences.
2116 o dist.dna() has been completely rewritten with a much faster
2117 (particularly for large data sets) C code. Eight models are
2118 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
2119 option `method' has been renamed `model'). Computation of variance
2120 is available for all models. A gamma-correction is possible for
2121 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
2122 to remove sites with missing data on a pairwise basis. The option
2123 `GCcontent' has been removed.
2125 o read.GenBank() has a new option (species.names) which specifies
2126 whether to return the species names of the organisms in addition
2127 to the accession numbers of the sequences (this is the default
2130 o write.nexus() can now write several trees in the same NEXUS file.
2132 o drop.tip() has a new option `root.edge' that allows to specify the
2133 new root edge if internal branches are trimmed.
2138 o as.phylo.hclust() failed if some labels had parentheses: this
2141 o Several bugs were fixed in all.equal.phylo(). This function now
2142 returns the logical TRUE if the trees are identical but with
2143 different representations (a report was printed previously).
2145 o read.GenBank() did not correctly handle ambiguous base codes:
2151 o birthdeath() now returns an object of class "birthdeath" for
2152 which there is a print method.
2156 CHANGES IN APE VERSION 1.4
2161 o The new function nj() performs phylogeny estimation with the
2162 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
2165 o The new function which.edge() identifies the edges of a tree
2166 that belong to a group specified as a set of tips.
2168 o The new function as.phylo.phylog() converts an object of class
2169 "phylog" (from the package ade4) into an object of class
2172 o The new function axisPhylo() draws axes on the side of a
2175 o The new function howmanytrees() calculates the number of trees
2176 in different cases and giving a number of tips.
2178 o write.tree() has a new option `multi.line' (TRUE by default) to
2179 write a Newick tree on several lines rather than on a single
2182 o The functionalities of zoom() have been extended. Several
2183 subtrees can be visualized at the same time, and they are marked
2184 on the main tree with colors. The context of the subtrees can be
2185 marked with the option `subtree' (see below).
2187 o drop.tip() has a new option `subtree' (FALSE by default) which
2188 specifies whether to output in the tree how many tips have been
2191 o The arguments of add.scale.bar() have been redefined and have
2192 now default values (see ?add.scale.bar for details). This
2193 function now works even if the plotted tree has no edge length.
2195 o plot.phylo() can now plot radial trees, but this does not take
2196 edge lengths into account.
2198 o In plot.phylo() with `type = "phylogram"', if the values of
2199 `edge.color' and `edge.width' are identical for sister-branches,
2200 they are propagated to the vertical line that link them.
2205 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
2206 crashing. This is fixed.
2208 o In plot.phylo(), the options `edge.color' and `edge.width' are
2209 now properly recycled; their default values are now "black" and
2212 o A bug has been fixed in write.nexus().
2217 o The function node.depth.edgelength() has been removed and
2218 replaced by a C code.
2222 CHANGES IN APE VERSION 1.3-1
2227 o The new function nodelabels() allows to add labels to the nodes
2228 of a tree using text or plotting symbols in a flexible way.
2230 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
2231 numeric values specifying the lower and upper limits on the x-
2232 and y-axes. This allows to leave some space on any side of the
2233 tree. If a single value is given, this is taken as the upper
2238 CHANGES IN APE VERSION 1.3
2243 o The new function phymltest() calls the software PHYML and fits
2244 28 models of DNA sequence evolution. There are a print method to
2245 display likelihood and AIC values, a summary method to compute
2246 the hierarchical likelihood ratio tests, and a plot method to
2247 display graphically the AIC values of each model.
2249 o The new function yule.cov() fits the Yule model with covariates,
2250 a model where the speciation rate is affected by several species
2251 traits through a generalized linear model. The parameters are
2252 estimated by maximum likelihood.
2254 o Three new functions, corBrownian(), corGrafen(), and
2255 corMartins(), compute the expected correlation structures among
2256 species given a phylogeny under different models of evolution.
2257 These can be used for GLS comparative phylogenetic methods (see
2258 the examples). There are coef() and corMatrix() methods and an
2259 Initialize.corPhyl() function associated.
2261 o The new function compar.cheverud() implements Cheverud et al.'s
2262 (1985; Evolution 39:1335) phylogenetic comparative method.
2264 o The new function varcomp() estimates variance components; it has
2267 o Two new functions, panel.superpose.correlogram() and
2268 plot.correlogramList(), allow to plot several phylogenetic
2271 o The new function node.leafnumber() computes the number of leaves
2272 of a subtree defined by a particular node.
2274 o The new function node.sons() gets all tags of son nodes from a
2277 o The new function compute.brlen() computes the branch lengths of
2278 a tree according to a specified method.
2280 o plot.phylo() has three new options: "cex" controls the size of
2281 the (tip and node) labels (thus it is no more needed to change
2282 the global graphical parameter), "direction" which allows to
2283 plot the tree rightwards, leftwards, upwards, or downwards, and
2284 "y.lim" which sets the upper limit on the y-axis.
2289 o Some functions which try to match tip labels and names of
2290 additional data (e.g. vector) are likely to fail if there are
2291 typing or syntax errors. If both series of names do not perfectly
2292 match, they are ignored and a warning message is now issued.
2293 These functions are bd.ext, compar.gee, pic. Their help pages
2294 have been clarified on this point.
2298 CHANGES IN APE VERSION 1.2-7
2303 o The new function root() reroots a phylogenetic tree with respect
2304 to a specified outgroup.
2306 o The new function rotate() rotates an internal branch of a tree.
2308 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
2309 trees) controls the display of the tip labels in unrooted trees.
2310 This display has been greatly improved: the tip labels are now not
2311 expected to overlap with the tree (particularly if lab4ut =
2312 "axial"). In all cases, combining appropriate values of "lab4ut"
2313 and the font size (via "par(cex = )") should result in readable
2314 unrooted trees. See ?plot.phylo for some examples.
2316 o In drop.tip(), the argument `tip' can now be numeric or character.
2321 o drop.tip() did not work correctly with trees with no branch
2322 lengths: this is fixed.
2324 o A bug in plot.phylo(..., type = "unrooted") made some trees being
2325 plotted with some line crossings: this is now fixed.
2329 CHANGES IN APE VERSION 1.2-6
2334 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
2335 correlogram.phylo, dist.taxo, plot.correlogram) have been added
2336 to implement comparative methods with an autocorrelation approach.
2338 o A new data set describing some life history traits of Carnivores
2344 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
2349 o When plotting a tree with plot.phylo(), the new default of the
2350 option `label.offset' is now 0, so the labels are always visible.
2354 CHANGES IN APE VERSION 1.2-5
2359 o The new function bd.ext() fits a birth-death model with combined
2360 phylogenetic and taxonomic data, and estimates the corresponding
2361 speciation and extinction rates.
2366 o The package gee is no more required by ape but only suggested
2367 since only the function compar.gee() calls gee.
2371 CHANGES IN APE VERSION 1.2-4
2376 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
2377 and lines.popsize) implementing a new approach for inferring the
2378 demographic history from genealogies using a reversible jump
2379 MCMC have been introduced.
2381 o The unit of time in the skyline plot and in the new plots can
2382 now be chosen to be actual years, rather than substitutions.
2386 CHANGES IN APE VERSION 1.2-3
2391 o The new function rtree() generates a random binary tree with or
2392 without branch lengths.
2394 o Two new functions for drawing lineages-through-time (LTT) plots
2395 are provided: ltt.lines() adds a LTT curve to an existing plot,
2396 and mltt.plot() does a multiple LTT plot giving several trees as
2397 arguments (see `?ltt.plot' for details).
2402 o Some taxon names made R crashing when calling as.phylo.hclust():
2405 o dist.dna() returned an error with two identical DNA sequences
2406 (only using the Jukes-Cantor method returned 0): this is fixed.
2411 o The function dist.phylo() has been re-written using a different
2412 algorithm: it is now about four times faster.
2414 o The code of branching.times() has been improved: it is now about
2419 CHANGES IN APE VERSION 1.2-2
2424 o The new function seg.sites() finds the segregating sites in a
2425 sample of DNA sequences.
2430 o A bug introduced in read.tree() and in read.nexus() with version
2433 o A few errors were corrected and a few examples were added in the
2438 CHANGES IN APE VERSION 1.2-1
2443 o plot.phylo() can now draw the edge of the root of a tree if it
2444 has one (see the new option `root.edge', its default is FALSE).
2449 o A bug was fixed in read.nexus(): files with semicolons inside
2450 comment blocks were not read correctly.
2452 o The behaviour of read.tree() and read.nexus() was corrected so
2453 that tree files with badly represented root edges (e.g., with
2454 an extra pair of parentheses, see the help pages for details)
2455 are now correctly represented in the object of class "phylo";
2456 a warning message is now issued.
2460 CHANGES IN APE VERSION 1.2
2465 o plot.phylo() has been completely re-written and offers several
2466 new functionalities. Three types of trees can now be drawn:
2467 phylogram (as previously), cladogram, and unrooted tree; in
2468 all three types the branch lengths can be drawn using the edge
2469 lengths of the phylogeny or not (e.g., if the latter is absent).
2470 The vertical position of the nodes can be adjusted with two
2471 choices (see option `node.pos'). The code has been re-structured,
2472 and two new functions (potentially useful for developpers) are
2473 documented separately: node.depth.edgelength() and node.depth();
2474 see the respective help pages for details.
2476 o The new function zoom() allows to explore very large trees by
2477 focusing on a small portion of it.
2479 o The new function yule() fits by maximum likelihood the Yule model
2480 (birth-only process) to a phylogenetic tree.
2482 o Support for writing DNA sequences in FASTA format has been
2483 introduced in write.dna() (support for reading sequences in
2484 this format was introduced in read.dna() in version 1.1-2).
2485 The function has been completely re-written, fixing some bugs
2486 (see below); the default behaviour is no more to display the
2487 sequences on the standard output. Several options have been
2488 introduced to control the sequence printing in a flexible
2489 way. The help page has been extended.
2491 o A new data set is included: a supertree of bats in NEXUS format.
2496 o In theta.s(), the default of the option `variance' has
2497 been changed to `FALSE' (as was indicated in the help page).
2499 o Several bugs were fixed in the code of all.equal.phylo().
2501 o Several bugs were fixed in write.dna(), particularly this
2502 function did not work with `format = "interleaved"'.
2504 o Various errors were corrected in the help pages.
2509 o The argument names of as.hclust.phylo() have been changed
2510 from "(phy)" to "(x, ...)" to conform to the definition of
2511 the corresponding generic function.
2513 o gamma.stat() has been renamed gammaStat() to avoid confusion
2514 since gamma() is a generic function.
2518 CHANGES IN APE VERSION 1.1-3
2523 o base.freq() previously did not return a value of 0 for
2524 bases absent in the data (e.g., a vector of length 3 was
2525 returned if one base was absent). This is now fixed (a
2526 vector of length 4 is always returned).
2528 o Several bugs were fixed in read.nexus(), including that this
2529 function did not work in this absence of a "TRANSLATE"
2530 command in the NEXUS file, and that the commands were
2535 CHANGES IN APE VERSION 1.1-2
2540 o The Tamura and Nei (1993) model of DNA distance is now implemented
2541 in dist.dna(): five models are now available in this function.
2543 o A new data set is included: a set of 15 sequences of the
2544 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2550 o A bug in read.nexus() was fixed.
2552 o read.dna() previously did not work correctly in most cases.
2553 The function has been completely re-written and its help page
2554 has been considerably extended (see ?read.dna for details).
2555 Underscores (_) in taxon names are no more replaced with
2556 spaces (this behaviour was undocumented).
2558 o A bug was fixed in write.dna().
2562 CHANGES IN APE VERSION 1.1-1
2567 o A bug in read.tree() introduced in APE 1.1 was fixed.
2569 o A bug in compar.gee() resulted in an error when trying to fit
2570 a model with `family = "binomial"'. This is now fixed.
2574 CHANGES IN APE VERSION 1.1
2579 o The Klastorin (1982) method as suggested by Misawa and Tajima
2580 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2581 on the basis of phylogenetic trees has been implemented (see
2582 the function klastorin()).
2584 o Functions have been added to convert APE's "phylo" objects in
2585 "hclust" cluster objects and vice versa (see the help page of
2586 as.phylo for details).
2588 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2589 are introduced for the estimation of absolute evolutionary rates
2590 (ratogram) and dated clock-like trees (chronogram) from
2591 phylogenetic trees using the non-parametric rate smoothing approach
2592 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2594 o A summary method is now provided printing a summary information on a
2595 phylogenetic tree with, for instance, `summary(tree)'.
2597 o The behaviour of read.tree() was changed so that all spaces and
2598 tabulations in tree files are now ignored. Consequently, spaces in tip
2599 labels are no more allowed. Another side effect is that read.nexus()
2600 now does not replace the underscores (_) in tip labels with spaces
2601 (this behaviour was undocumented).
2603 o The function plot.phylo() has a new option (`underscore') which
2604 specifies whether the underscores in tip labels should be written on
2605 the plot as such or replaced with spaces (the default).
2607 o The function birthdeath() now computes 95% confidence intervals of
2608 the estimated parameters using profile likelihood.
2610 o Three new data sets are included: a gene tree estimated from 36
2611 landplant rbcL sequences, a gene tree estimated from 32 opsin
2612 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2617 o A bug was fixed in dist.gene() where nothing was returned.
2619 o A bug in plot.mst() was fixed.
2621 o A bug in vcv.phylo() resulted in false correlations when the
2622 option `cor = TRUE' was used (now fixed).
2626 CHANGES IN APE VERSION 1.0
2631 o Two new functions, read.dna() and write.dna(), read/write in a file
2632 DNA sequences in interleaved or in sequential format.
2634 o Two new functions, read.nexus() and write.nexus(), read/write trees
2637 o The new function bind.tree() allows to bind two trees together,
2638 possibly handling root edges to give internal branches.
2640 o The new function drop.tip() removes the tips in a phylogenetic tree,
2641 and trims (or not) the corresponding internal branches.
2643 o The new function is.ultrametric() tests if a tree is ultrametric.
2645 o The function plot.phylo() has more functionalities such as drawing the
2646 branches with different colours and/or different widths, showing the
2647 node labels, controling the position and font of the labels, rotating
2648 the labels, and controling the space around the plot.
2650 o The function read.tree() can now read trees with no branch length,
2651 such as "(a,b),c);". Consequently, the element `edge.length' in
2652 objects of class "phylo" is now optional.
2654 o The function write.tree() has a new default behaviour: if the default
2655 for the option `file' is used (i.e. file = ""), then a variable of
2656 mode character containing the tree in Newick format is returned which
2657 can thus be assigned (e.g., tree <- write.tree(phy)).
2659 o The function read.tree() has a new argument `text' which allows
2660 to read the tree in a variable of mode character.
2662 o A new data set is included: the phylogenetic relationships among
2663 the orders of birds from Sibley and Ahlquist (1990).
2667 CHANGES IN APE VERSION 0.2-1
2672 o Several bugs were fixed in the help pages.
2676 CHANGES IN APE VERSION 0.2
2681 o The function write.tree() writes phylogenetic trees (objects of class
2682 "phylo") in an ASCII file using the Newick parenthetic format.
2684 o The function birthdeath() fits a birth-death model to branching times
2685 by maximum likelihood, and estimates the corresponding speciation and
2688 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2691 o The function is.binary.tree() tests whether a phylogeny is binary.
2693 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2694 as well as some methods are introduced.
2696 o Several functions, including some generics and methods, for computing
2697 skyline plot estimates (classic and generalized) of effective
2698 population size through time are introduced and replace the function
2699 skyline.plot() in version 0.1.
2701 o Two data sets are now included: the phylogenetic relationships among
2702 the families of birds from Sibley and Ahlquist (1990), and an
2703 estimated clock-like phylogeny of HIV sequences sampled in the
2704 Democratic Republic of Congo.
2707 DEPRECATED & DEFUNCT
2709 o The function skyline.plot() in ape 0.1 has been deprecated and
2710 replaced by more elaborate functions (see above).
2715 o Two important bugs were fixed in plot.phylo(): phylogenies with
2716 multichotomies not at the root or not with only terminal branches,
2717 and phylogenies with a single node (i.e. only terminal branches)
2718 did not plot. These trees should be plotted correctly now.
2720 o Several bugs were fixed in diversi.time() in the computation of
2723 o Various errors were corrected in the help pages.
