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).
10 o The three new functions node.depth.edgelength, node.height, and
11 node.height.clado make some internal code available from R. See
12 ?node.depth (which was already available and documented) for
18 o reorder(, "pruningwise") made R crash if the rows of the edge
19 matrix are in random order: this is now fixed.
21 o drop.tip() sometimes shuffled node labels (thanks to Rebecca Best
27 o dist.nodes() is now 6 to 10 times faster.
29 o reorder(, "cladewise") is now faster. The change is not very
30 visible for small trees (n < 1000) but this can be more than
31 1000 faster for big trees (n >= 1e4).
33 o The attribute "order" of the objects of class "phylo" is now
34 strongly recommended, though not mandatory. Most functions in
35 ape should return a tree with this attribute correctly set.
37 o dbd() is now vectorized on both arguments 'x' (number of species
38 in clade) and 't' (clade age) to make likelihood calculations
43 CHANGES IN APE VERSION 3.0-5
48 o ace() should better catch errors when SEs cannot be computed.
53 o write.dna(format = "fasta") now conforms more closely to the
54 FASTA standard thanks to François Michonneau.
56 o print.DNAbin() does not print base compositions if there are more
57 than one million nucleotides.
61 CHANGES IN APE VERSION 3.0-4
66 o read.dna() failed to read Phylip files if the first line used
67 tabulations instead of white spaces.
69 o read.dna() failed to read Phylip or Clustal files with less than
70 10 nucleotides. (See other changes in this function below.)
74 o read.dna() now requires at least one space (or tab) between the
75 taxa names and the sequences (whatever the length of taxa
76 names). write.dna() now follows the same rule.
78 o The option 'seq.names' of read.dna has been removed.
80 o The files ape-defunct.R and ape-defunct.Rd, which have not been
81 modified for almost two years, have been removed.
83 o The C code of bionj() has been reworked: it is more stable (by
84 avoiding passing character strings), slightly faster (by about
85 20%), and numerically more accurate.
87 o The C code of fastme.*() has been slightly modified and should
88 be more stable by avoiding passing character strings (the
89 results are identical to the previous versions).
91 o The file src/newick.c has been removed.
95 CHANGES IN APE VERSION 3.0-3
100 o birthdeath() now catches errors and warnings much better so that
101 a result is returned in most cases.
106 o Because of problems with character string manipulation in C, the
107 examples in ?bionj and in ?fastme have been disallowed. In the
108 meantime, these functions might be unstable. This will be solved
109 for the next release.
113 CHANGES IN APE VERSION 3.0-2
118 o The new function alex (alignment explorator) zooms in a DNA
119 alignment and opens the result in a new window.
124 o compute.brtime() did not completely randomized the order of the
127 o write.nexus() did not work correctly with rooted trees (thanks
128 to Matt Johnson for the fix).
130 o mltt.plot(, backward = FALSE) did not set the x-axis correctly.
132 o A bug was introduced in prop.clades() with ape 3.0. The help page
133 has been clarified relative to the use of the option 'rooted'.
135 o mantel.test() printed a useless warning message.
137 o plot.phylo(, direction = "downward") ignored 'y.lim'.
139 o is.monophyletic() did not work correctly if 'tips' was not stored
142 o prop.part() could make R crash if the first tree had many
145 o njs(), bionjs(), and mvrs() now return an error if 'fs < 1'.
147 o SDM() did not work correctly. The code has also been generally
153 o The DESCRIPTION file has been updated.
155 o The option 'original.data' of write.nexus() has been removed.
157 o The files bionjs.c, mvr.c, mvrs.c, njs.c, triangMtd.c, and
158 triangMtds.c have been improved which should fix some bugs in
159 the corresponding functions.
161 o dist.gene() now coerces input data frame as matrix resulting in
162 much faster calculations (thanks to a suggestion by Markus
167 CHANGES IN APE VERSION 3.0-1
172 o dist.dna() has two new models: "indel" and "indelblock".
174 o bind.tree() now accepts 'position' > 0 when the trees have no
175 banch length permitting to create a node in 'x' when grafting
176 'y' (see ?bind.tree for details).
181 o cophyloplot( , rotate = TRUE) made R hanged after a few clicks.
182 Also the tree is no more plotted twice.
184 o read.GenBank() has been updated to work with EFetch 2.0.
186 o unroot() on trees in "pruningwise" order did not respect this
191 CHANGES IN APE VERSION 3.0
196 o The three functions dyule, dbd, and dbdTime calculate the
197 density probability (i.e., the distribution of the number of
198 species) for the Yule, the constant and the time-dependent
199 birth-beath models, respectively. These probabilities can be
200 conditional on no extinction and/or on a log-scale.
202 o plot.phylo() has a new option 'rotate.tree' to rotate unrooted,
203 fan, or radial trees around the center of the plot.
205 o boot.phylo() and prop.clades() have a new option rooted =
206 FALSE. Note that the behaviour of prop.part() is unchanged.
208 o edgelabels() has a new option 'date' to place labels on edges of
209 chronograms using the time scale (suggestion by Rob Lanfear).
214 o In chronopl(), the code setting the initial dates failed in
215 complicated settings (several dates known within intervals).
216 This has been generally improved and should result in faster
217 and more efficient convergence even in simple settings.
219 o mantel.test() sometimes returned P-values > 1 with the default
222 o extract.clade() sometimes shuffled some tip labels (thanks to
223 Ludovic Mallet and Mahendra Mariadassou for the fix).
225 o clustal() should now find by default the executable under Windows.
230 o The code of yule() has been simplified and is now much faster for
233 o The code of mantel.test() has been adjusted to be consistent
234 with common permutation tests.
236 o The C code of base.freq() has been improved and is now nearly 8
239 o The option 'original.data' of write.nexus() is now deprecated and
240 will be removed in a future release.
242 o The code of is.ultrametric() has been improved and is now 3 times
245 o The code of vcv.phylo() has been improved and is now 10 or 30
246 times faster for 100 or 1000 tips, respectively. Consequently,
247 fitting models with PGLS will be faster overall.
251 CHANGES IN APE VERSION 2.8
256 o Twelve new functions have been written by Andrei-Alin Popescu:
257 additive, ultrametric, is.compatible, arecompatible, mvr, mvrs,
258 njs, bionjs, SDM, treePop, triangMtd, triangMtd*.
260 o A new class "bitsplits" has been created by Andrei-Alin Popescu
261 to code splits (aka, bipartition).
263 o There is a new generic function as.bitsplits with a method to
264 convert from the class "prop.part" to the class "bitsplits".
266 o The new function ltt.coplot plots on the same scales a tree and
267 the derived LTT plot.
269 o ltt.plot() has two new options: backward and tol. It can now
270 handle non-ultrametic trees and its internal coding has been
271 improved. The coordinates of the plot can now be computed with
272 the new function ltt.plot.coords.
277 o prop.part() crashed if some trees had some multichotomies.
281 CHANGES IN APE VERSION 2.7-3
286 o The new function compute.brtime computes and sets branching times.
288 o mantel.test() has a new argument 'alternative' which is
289 "two-sided" by default. Previously, this test was one-tailed
290 with no possibility to change.
292 o ace() can now do REML estimation with continuous characters,
293 giving better estimates of the variance of the Brownian motion
299 o Branch lengths were wrongly updated with bind.tree(, where = <tip>,
300 position = 0). (Thanks to Liam Revell for digging this bug out.)
302 o Simulation of OU process with rTraitCont() did not work correctly.
303 This now uses formula from Gillespie (1996) reduced to a BM
304 process when alpha = 0 to avoid division by zero. The option
305 'linear' has been removed.
307 o Cross-validation in chronopl() did not work when 'age.max' was
310 o consensus(, p = 0.5) could return an incorrect tree if some
311 incompatible splits occur in 50% of the trees (especially with
312 small number of trees).
314 o c() with "multiPhylo" did not work correctly (thanks to Klaus
315 Schliep for the fix).
317 o root() failed in some cases with an outgroup made of several tips.
318 The help page has been clarified a bit.
322 CHANGES IN APE VERSION 2.7-2

328 a constructor function evonet(), a print() and a plot() methods,
329 and four conversion methods to the classes "phylo", "networx",
330 "network", and "igraph".
332 o The new function rTraitMult does multivariate traits simulation
333 with user-defined models.
335 o plot.phylo() has a new option 'plot = TRUE'. If FALSE, the tree
336 is not plotted but the graphical device is set and the
337 coordinates are saved as usual.
339 o diversity.contrast.test() gains a fourth version of the test with
340 method = "logratio"; the literature citations have been clarified.
342 o add.scale.bar() has two new options, 'lwd' and 'lcol', to modify
343 the aspect of the bar.
345 o boot.phylo() now displays a progress bar by default (can be off
348 o There is a new predict() method for compar.gee().
353 o bionj() made R crash if distances were too large. It now returns
354 an error if at least one distance is greater than 100.
356 o drop.tip() returned a wrong tree if 'tip' was of zero length.
358 o read.nexus.data() failed with URLs.
360 o boot.phylo() returned overestimated support values in the
361 presence of identical or nearly identical sequences.
366 o The data bird.families, bird.orders, cynipids, and woodmouse are
367 now provided as .rda files.

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

427 richness.yule.test, and slowinskiguyer.test, implement various
428 tests of diversification shifts using sister-clade comparisons.
430 o base.freq() gains an option 'all' to count all the possible bases
431 including the ambiguous ones (defaults to FALSE).
433 o read.nexus() now writes tree names in the NEXUS file if given a
434 list of trees with names.
439 o prop.part() failed in some situations with unrooted trees.

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

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

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

553 o as.list.DNAbin() did not work correctly with vectors.
555 o as.hclust.phylo() failed with trees with node labels (thanks to
556 Filipe Vieira for the fix).
560 CHANGES IN APE VERSION 2.6
565 o The new functions rlineage and rbdtree simulate phylogenies under
566 any user-defined time-dependent speciation-extinction model. They
567 use continuous time algorithms.
569 o The new function drop.fossil removes the extinct species from a
572 o The new function bd.time fits a user-defined time-dependent
573 birth-death model. It is a generalization of yule.time() taking
574 extinction into account.
576 o The new function MPR does most parsimonious reconstruction of
579 o The new function Ftab computes the contingency table of base
580 frequencies from a pair of sequences.

585 with the option model = "Ts" or model = "Tv", respectively.
587 o [node|tip|edge]labels() gain three options with default values to
588 control the aspect of thermometers: horiz = TRUE, width = NULL,
591 o compar.gee() has been improved with the new option 'corStruct' as an
592 alternative to 'phy' to specify the correlation structure, and
593 calculation of the QIC (Pan 2001, Biometrics). The display of the
594 results has also been improved.
596 o read.GenBank() has a new option 'gene.names' to return the name of
597 the gene (FALSE by default).
602 o extract.clade() sometimes shuffled the tip labels.
604 o plot.phylo(type = "unrooted") did not force asp = 1 (thanks to Klaus
607 o dist.dna(model = "logdet") used to divide distances by 4. The
608 documentation has been clarified on the formulae used.
613 o rTraitCont(model = "OU") has an option 'linear = TRUE' to possibly
614 change the parameterisation (see ?rTraitCont for details).
616 o pic() now returns a vector with the node labels of the tree (if
619 o write.tree() and read.tree() have been substantially improved thanks
620 to contributions by Klaus Schliep.
624 CHANGES IN APE VERSION 2.5-3
629 o The new function mixedFontLabel helps to make labels with bits of
630 text to be plotted in different fonts.
632 o There are now replacement operators for [, [[, and $ for the class
633 "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They possibly
634 check that the tip labels are the same in all trees.
636 o Objects of class "multiPhylo" can be built with c(): there are
637 methods for the classes "phylo" and "multiPhylo".
639 o The internal functions .compressTipLabel and .uncompressTipLabel are
645 o bind.tree(x, y, where, position = 0) did not work correctly if 'y'
646 was a single-edge tree and 'where' was a tip.

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

729 o plot.phylo(direction = "l", x.lim = 30) failed to plot the branches
730 in the correct direction though the tip labels were displayed
736 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
737 the sequences are correctly stored (in a list for c, in a matrix
738 for the two other functions).
742 CHANGES IN APE VERSION 2.5
747 o The new function parafit by Pierre Legendre tests for the
748 coevolution between hosts and parasites. It has a companion
749 function, pcoa, that does principal coordinate decomposition.
750 The latter has a biplot method.
752 o The new function lmorigin by Pierre Legendre performs multiple
753 regression through the origin with testing by permutation.
755 o The new functions rTraitCont and rTraitDisc simulate continuous and
756 discrete traits under a wide range of evolutionary models.
758 o The new function delta.plot does a delta plot following Holland et
759 al. (2002, Mol. Biol. Evol. 12:2051).
761 o The new function edges draws additional branches between any nodes
762 and/or tips on a plotted tree.
764 o The new function fancyarrows enhances arrows from graphics with
765 triangle and harpoon heads; it can be called from edges().
767 o add.scale.bar() has a new option 'ask' to draw interactively.
769 o The branch length score replaces the geodesic distance in dist.topo.
771 o Three new data sets are included: the gopher-lice data (gopher.D),
772 SO2 air pollution in 41 US cities (lmorigin.ex1, from Sokal &
773 Rohlf 1995), and some host-parasite specificity data
774 (lmorigin.ex2, from Legendre & Desdevises 2009).
779 o add.scale.bar() drew the bar outside the plotting region with the
780 default options with unrooted or radial trees.
782 o dist.topo() made R stuck when the trees had different sizes (thanks
783 to Otto Cordero for the fix).
788 o The geodesic distance has been replaced by the branch length score
793 CHANGES IN APE VERSION 2.4-1
798 o rtree() and rcoal() now accept a numeric vector for the 'br'
801 o vcv() is a new generic function with methods for the classes "phylo"
802 and "corPhyl" so that it is possible to calculate the var-cov matrix
803 for "transformation models". vcv.phylo() can still be used for trees
804 of class "phylo"; its argument 'cor' has been renamed 'corr'.
809 o bind.tree() failed when 'y' had no root edge.
811 o read.nexus() shuffled tip labels when the trees have no branch
812 lengths and there is a TRANSLATE block.
814 o read.nexus() does not try to translate node labels if there is a
815 translation table in the NEXUS file. See ?read.nexus for a
816 clarification on this behaviour.
818 o plot.multiPhylo() crashed R when plotting a list of trees with
819 compressed tip labels.
821 o write.nexus() did not translate the taxa names when asked for.
823 o plot.phylo(type = "fan") did not rotate the tip labels correctly
824 when the tree has branch lengths.
826 o ace(type = "continuous", method = "ML") now avoids sigma² being
827 negative (which resulted in an error).
829 o nj() crashed with NA/NaN in the distance matrix: an error in now
834 CHANGES IN APE VERSION 2.4
839 o base.freq() has a new option 'freq' to return the counts; the
840 default is still to return the proportions.
845 o seg.sites() did not handle ambiguous nucleotides correctly: they
848 o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
849 the tree: the argument is now ignored.
851 o add.scale.bar() failed when 'x' and 'y' were given (thanks to Janet
857 o Trying to plot a tree with a single tip now returns NULL with a
858 warning (it returned an error previously).
860 o The way lines representing nodes are coloured in phylograms has
861 been modified (as well as their widths and types) following some
862 users' request; this is only for dichotomous nodes.
864 o The argument 'adj' in [node][tip][edge]labels() now works when
865 using 'pie' or 'thermo'.
867 o A more informative message error is now returned by dist.dna() when
868 'model' is badly specified (partial matching of this argument is
871 o Deprecated functions are now listed in a help page: see
872 help("ape-defunct") with the quotes.
877 o The functions heterozygosity, nuc.div, theta.h, theta.k and
878 theta.s have been moved from ape to pegas.

905 o root() shuffled node labels with 'resolve.root = TRUE'.
909 CHANGES IN APE VERSION 2.3-2
914 o all.equal.phylo() did not compare unrooted trees correctly.
916 o dist.topo(... method = "PH85") did not treat unrooted trees
917 correctly (thanks to Tim Wallstrom for the fix).
919 o root() sometimes failed to test for the monophyly of the
922 o extract.clade() sometimes included too many edges.
924 o vcv.phylo() did not work correctly when the tree is in
927 o nj() did not handle correctly distance matrices with many 0's.
928 The code has also been significantly improved: 7, 70, 160 times
929 faster with n = 100, 500, 1000, respectively.

1030 CHANGES IN APE VERSION 2.2-4
1034 o The bug fix in read.nexus() in version 2.2-3 was wrong: this is
1035 now fixed. (Thanks to Peter Wragg for the fix!)
1037 o A warning message occurred for no reason with ace(method="GLS").
1042 o There is now a general help page displayed with '?ape'.

1070 the number of lineages with non-binary trees.
1075 o ape has now a namespace.
1077 o drop.tip() has been improved: it should be much faster and work
1078 better in some cases (e.g., see the example in ?zoom).
1082 CHANGES IN APE VERSION 2.2-2
1087 o dist.gene() has been substantially improved and gains an option
1088 'pairwise.deletion'.
1090 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
1096 o prop.part() failed with a single tree with the default option
1097 'check.labels = TRUE'.
1099 o summary.DNAbin() failed to display correctly the summary of
1100 sequence lengths with lists of sequences of 10,000 bases or more
1101 (because summary.default uses 4 significant digits by default).
1103 o read.nexus() failed to read a file with a single tree with line
1104 breaks in the Newick string.
1106 o del.gaps() returned a list of empty sequences when there were no
1112 o phymltest() has been updated for PhyML 3.0 and gains an option
1113 'append', whereas the option 'path2exec' has been removed.
1115 o rbind.DNAbin() and cbind.DNAbin() now accept a single matrix
1116 which is returned unchanged (instead of an error).
1118 o The data sets bird.orders and bird.families are now stored as
1119 Newick strings; i.e., the command data(bird.orders) calls
1124 CHANGES IN APE VERSION 2.2-1
1129 o The new function makeLabel() helps to modify labels of trees,
1130 lists of trees, or DNA sequences, with several utilities to
1131 truncate and/or make them unique, substituting some
1132 characters, and so on.
1134 o The new function del.gaps() removes insertion gaps ("-") in a
1135 set of DNA sequences.

1181 graphical exploration of large trees (cophyloplot, subtrees,
1182 subtreeplot), and to return the graphical coordinates of tree
1185 o The new functions corPagel and corBlomberg implement the Pagel's
1186 "lambda" and Blomberg et al.'s "ACDC" correlation structures.
1188 o chronopl() has been improved and gains several options: see its
1189 help page for details.

1247 (FALSE by default) as well as its code being improved.
1249 o mltt.plot() has now an option 'log' used in the same way
1250 than in plot.default().
1255 o mltt.plot() failed to display the legend with an unnamed
1258 o nodelabels() with pies now correcly uses the argument
1259 'cex' to draw symbols of different sizes (which has
1260 worked already for thermometers).
1262 o read.nexus() generally failed to read very big files.
1267 o The argument 'family' of compar.gee() can now be a function
1268 as well as a character string.
1270 o read.tree() and read.nexus() now return an unnamed list if
1271 'tree.names = NULL'.
1273 o read.nexus() now returns a modified object of class "multiPhylo"
1274 when there is a TRANSLATE block in the NEXUS file: the individual
1275 trees have no 'tip.label' vector, but the list has a 'TipLabel'
1276 attribute. The new methods '$' and '[[' set these elements
1277 correctly when extracting trees.
1281 CHANGES IN APE VERSION 2.1-1
1286 o The new function rmtree generates lists of random trees.
1288 o rcoal() now generates a genuine coalescent tree by default

1317 "multiPhylo") with "[" while keeping its class correct.
1319 o The new function as.DNAbin.alignment converts DNA sequences
1320 stored in the "alignment" format of the package seqinr into
1321 an object of class "DNAbin".
1323 o The new function weight.taxo2 helps to build similarity matrices
1324 given two taxonomic levels (usually called by other functions).

1327 as its main argument.
1329 o plot.correlogram() and plot.correlogramList() have been
1330 improved, and gain several options (see the help page for
1331 details). A legend is now plotted by default.
1336 o dist.dna() returned some incorrect values with `model = "JC69"'
1337 and `pairwise.deletion = TRUE'. This affected only the
1338 distances involving sequences with missing values. (Thanks
1339 to Bruno Toupance for digging this bug out.)
1341 o write.tree() failed with some trees: this is fixed by removing
1342 the `multi.line' option (trees are now always printed on a
1345 o read.nexus() did not correctly detect trees with multiple root
1346 edges (see OTHER CHANGES).
1351 o The code of mlphylo() has been almost entirely rewritten, and
1352 should be much stabler. The options have been also greatly
1353 simplified (see ?mlphylo and ?DNAmodel for details).
1355 o The internal function nTips has been renamed klastorin_nTips.
1357 o The code of is.ultrametric() contained redundancies and has
1360 o The code of Moran.I() and of correlogram.formula() have been
1363 o read.tree() and read.nexus() now return an error when trying to
1364 read a tree with multiple root edges (see BUG FIXES). The
1365 correction applied in previous version did not work in all
1368 o The class c("multi.tree", "phylo") has been renamed
1374 o There is now a vignette in ape: see vignette("MoranI", "ape").
1377 DEPRECATED & DEFUNCT

1394 o The new function unique.multi.tree removes duplicate trees from
1397 o yule() has a new option `use.root.edge = FALSE' that specifies
1398 to ignore, by default, the root edge of the tree if it exists.
1403 o which.edge() failed when the index of a single terminal edge was
1406 o In diversi.time(), the values returned for model C were
1409 o A bug was fixed in yule() that affected the calculation of the
1410 likelihood in the presence of ties in the branching times.
1412 o There was a bug in the C function mat_expo4x4 affecting the
1413 calculations of the transition probabilities for models HKY and
1416 o A small bug was fixed in as.matrix.DNAbin (thanks to James
1419 o rtree() did not `shuffle' the tip labels by default, so only a
1420 limited number of labelled topologies could be generated.
1424 CHANGES IN APE VERSION 2.0-1
1429 o The three new functions bionj, fastme.ols, and fastme.bal
1430 perform phylogeny estimation by the BIONJ and fastME methods in
1431 OLS and balanced versions. This is a port to R of previous
1432 previous programs done by Vincent Lefort.
1434 o The new function chronoMPL performs molecular dating with the
1435 mean path lengths method of Britton et al. (2002, Mol. Phyl.
1438 o The new function rotate, contributed by Christoph Heibl, swaps
1439 two clades connected to the same node. It works also with
1440 multichotomous nodes.
1442 o The new `method' as.matrix.DNAbin() may be used to convert
1443 easily DNA sequences stored in a list into a matrix while
1444 keeping the names and the class.
1449 o chronopl() failed when some branch lengths were equal to zero:
1450 an error message is now returned.
1452 o di2multi() failed when there was a series of consecutive edges
1457 CHANGES IN APE VERSION 1.10-2
1462 o plot.phylo() can now plot circular trees: the option is type =
1463 "fan" or type = "f" (to avoid the ambiguity with type = "c").
1465 o prop.part() has a new option `check.labels = FALSE' which allows
1466 to considerably speed-up the calculations of bipartitions. As a
1467 consequence, calculations of bootstrap values with boot.phylo()
1468 should be much faster.
1473 o read.GenBank() did not return correctly the list of species as
1474 from ape 1.10: this is fixed in this version
1476 o Applying as.phylo() on a tree of class "phylo" failed: the
1477 object is now returned unchanged.

1486 o The three new functions Ntip, Nnode, and Nedge return, for a
1487 given tree, the number of tips, nodes, or edges, respectively.
1492 o read.nexus() did not set correctly the class of the returned
1493 object when reading multiple trees.
1495 o mllt.plot() failed with objects of class c("multi.tree",
1498 o unroot() did not work correctly in most cases.
1500 o reorder.phylo() made R freeze in some occasions.
1502 o Plotting a tree in pruningwise order failed.
1504 o When plotting an unrooted tree, the tip labels where not all
1505 correctly positioned if the option `cex' was used.
1509 CHANGES IN APE VERSION 1.10
1514 o Five new `method' functions have been introduced to manipulate
1515 DNA sequences in binary format (see below).
1517 o Three new functions have been introduced to convert between the
1518 new binary and the character formats.
1520 o The new function as.alignment converts DNA sequences stored as
1521 single characters into the class "alignment" used by the package
1524 o read.dna() and read.GenBank() have a new argument `as.character'
1525 controlling whether the sequences are returned in binary format
1531 o root() failed when the tree had node labels: this is fixed.
1533 o plot.phylo() did not correctly set the limits on the y-axis with
1534 the default setting: this is fixed.
1536 o dist.dna() returned a wrong result for the LogDet, paralinear,
1537 and BH87 models with `pairwise.deletion = TRUE'.
1542 o DNA sequences are now internally stored in a binary format. See
1543 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1544 details. Most functions analyzing DNA functions have been
1545 modified accordingly and are now much faster (dist.dna is now
1546 ca. 60 times faster).
1550 CHANGES IN APE VERSION 1.9-4
1555 o A bug was fixed in edgelabels().
1557 o as.phylo.hclust() did not work correctly when the object of
1558 class "hclust" has its labels set to NULL: the returned tree has
1559 now its tip labels set to "1", "2", ...
1561 o consensus could fail if some tip labels are a subset of others
1562 (e.g., "a" and "a_1"): this is now fixed.
1564 o mlphylo() failed in most cases if some branch lengths of the
1565 initial tree were greater than one: an error message is now
1568 o mlphylo() failed in most cases when estimating the proportion of
1569 invariants: this is fixed.
1573 CHANGES IN APE VERSION 1.9-3
1578 o The new function edgelabels adds labels on the edge of the tree
1579 in the same way than nodelabels or tiplabels.
1584 o multi2di() did not handle correctly branch lengths with the
1585 default option `random = TRUE': this is now fixed.
1587 o A bug was fixed in nuc.div() when using pairwise deletions.
1589 o A bug occurred in the analysis of bipartitions with large
1590 numbers of large trees, with consequences on prop.part,
1591 prop.clades, and boot.phylo.
1593 o The calculation of the Billera-Holmes-Vogtmann distance in
1594 dist.topo was wrong: this has been fixed.
1598 CHANGES IN APE VERSION 1.9-2
1603 o The new function ladderize reorganizes the internal structure of
1604 a tree to plot them left- or right-ladderized.
1606 o The new function dist.nodes computes the patristic distances
1607 between all nodes, internal and terminal, of a tree. It replaces
1608 the option `full = TRUE' of cophenetic.phylo (see below).
1613 o A bug was fixed in old2new.phylo().
1615 o Some bugs were fixed in chronopl().
1617 o The edge colours were not correctly displayed by plot.phylo
1618 (thank you to Li-San Wang for the fix).
1620 o cophenetic.phylo() failed with multichotomous trees: this is
1626 o read.dna() now returns the sequences in a matrix if they are
1627 aligned (interleaved or sequential format). Sequences in FASTA
1628 format are still returned in a list.
1630 o The option `full' of cophenetic.phylo() has been removed because
1631 it could not be used from the generic.
1634 DEPRECATED & DEFUNCT
1636 o rotate() has been removed; this function did not work correctly
1641 CHANGES IN APE VERSION 1.9-1
1646 o Trees with a single tip were not read correctly in R as the
1647 element `Nnode' was not set: this is fixed.
1649 o unroot() did not set correctly the number of nodes of the
1650 unrooted tree in most cases.
1652 o read.GenBank() failed when fetching very long sequences,
1653 particularly of the BX-series.
1655 o A bug was introduced in read.tree() with ape 1.9: it has been
1660 CHANGES IN APE VERSION 1.9
1665 o There are two new print `methods' for trees of class "phylo" and
1666 lists of trees of class "multi.tree", so that they are now
1667 displayed in a compact and informative way.
1669 o There are two new functions, old2new.phylo and new2old.phylo,
1670 for converting between the old and new coding of the class
1673 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1674 LogDet ("logdet"), and paralinear ("paralin").
1676 o compute.brlen() has been extended: several methods are now
1677 available to compute branch lengths.
1679 o write.dna() can now handle matrices as well as lists.
1684 o cophenetic.phylo() sometimes returned a wrong result with
1685 multichotomous trees: this is fixed.
1687 o rotate() failed when a single tip was specified: the tree is now
1690 o ace() did not return the correct index matrix with custom
1691 models: this is fixed.
1693 o multi2di() did not work correctly when resolving multichotomies
1694 randomly: the topology was always the same, only the arrangement
1695 of clades was randomized: this is fixed. This function now
1696 accepts trees with no branch lengths.
1698 o The output of diversi.gof() was blurred by useless prints when a
1699 user distribution was specified. This has been corrected, and
1700 the help page of this function has been expanded.
1705 o The internal structure of the class "phylo" has been changed:
1706 see the document "Definition of Formats for Coding Phylogenetic
1707 Trees in R" for the details. In addition, the code of most
1708 functions has been improved.
1710 o Several functions have been improved by replacing some R codes
1711 by C codes: pic, plot.phylo, and reorder.phylo.
1713 o There is now a citation information: see citation("ape") in R.
1715 o write.tree() now does not add extra 0's to branch lengths so
1716 that 1.23 is printed "1.23" by default, not "1.2300000000".
1718 o The syntax of bind.tree() has been simplified. This function now
1719 accepts trees with no branch lengths, and handles correctly node
1722 o The option `as.numeric' of mrca() has been removed.
1724 o The unused options `format' and `rooted' of read.tree() have
1727 o The unused option `format' of write.tree() has been removed.
1729 o The use of node.depth() has been simplified.
1733 CHANGES IN APE VERSION 1.8-5
1738 o Two new functions read.nexus.data() and write.nexus.data(),
1739 contributed by Johan Nylander, allow to read and write molecular
1740 sequences in NEXUS files.
1742 o The new function reorder.phylo() reorders the internal structure
1743 of a tree of class "phylo". It is used as the generic, e.g.,
1746 o read.tree() and read.nexus() can now read trees with a single
1749 o The new data set `cynipids' supplies a set of protein sequences
1755 o The code of all.equal.phylo() has been completely rewritten
1756 (thanks to Benoît Durand) which fixes several bugs.
1758 o read.tree() and read.nexus() now checks the labels of the tree
1759 to remove or substitute any characters that are illegal in the
1760 Newick format (parentheses, etc.)
1762 o A negative P-value could be returned by mantel.test(): this is
1767 CHANGES IN APE VERSION 1.8-4
1772 o The new function sh.test() computes the Shimodaira-
1775 o The new function collapse.singles() removes the nodes with a
1776 single descendant from a tree.
1778 o plot.phylo() has a new argument `tip.color' to specify the
1779 colours of the tips.
1781 o mlphylo() has now an option `quiet' to control the display of
1782 the progress of the analysis (the default is FALSE).
1787 o read.dna() did not read correctly sequences in sequential format
1788 with leading alignment gaps "-": this is fixed.
1790 o ace() returned a list with no class so that the generic
1791 functions (anova, logLik, ...) could not be used directly. This
1792 is fixed as ace() now returns an object of class "ace".
1794 o anova.ace() had a small bug when computing the number of degrees
1795 of freedom: this is fixed.
1797 o mlphylo() did not work when the sequences were in a matrix or
1798 a data frame: this is fixed.
1800 o rtree() did not work correctly when trying to simulate an
1801 unrooted tree with two tips: an error message is now issued.
1806 o The algorithm of rtree() has been changed: it is now about 40,
1807 100, and 130 times faster for 10, 100, and 1000 tips,
1812 CHANGES IN APE VERSION 1.8-3
1817 o There are four new `method' functions to be used with the
1818 results of ace(): logLik(), deviance(), AIC(), and anova().
1820 o The plot method of phymltest has two new arguments: `main' to
1821 change the title, and `col' to control the colour of the
1822 segments showing the AIC values.
1824 o ace() has a new argument `ip' that gives the initial values used
1825 in the ML estimation with discrete characters (see the examples
1826 in ?ace). This function now returns a matrix giving the indices
1827 of the estimated rates when analysing discrete characters.
1829 o nodelabels() and tiplabels() have a new argument `pie' to
1830 represent proportions, with any number of categories, as
1831 piecharts. The use of the option `thermo' has been improved:
1832 there is now no limitation on the number of categories.
1837 o mlphylo() did not work with more than two partitions: this is
1840 o root() failed if the proposed outgroup was already an outgroup
1841 in the tree: this is fixed.
1843 o The `col' argument in nodelabels() and tiplabels() was not
1844 correctly passed when `text' was used: this is fixed.
1846 o Two bugs were fixed in mlphylo(): parameters were not always
1847 correctly output, and the estimation failed in some cases.
1849 o plot.phylo() was stuck when given a tree with a single tip: this
1850 is fixed and a message error is now returned.
1852 o An error was corrected in the help page of gammaStat regarding
1853 the calculation of P-values.
1855 o Using gls() could crash R when the number of species in the tree
1856 and in the variables were different: this is fixed.

1865 o The new function mlphylo() fits a phylogenetic tree by maximum
1866 likelihood from DNA sequences. Its companion function DNAmodel()
1867 is used to define the substitution model which may include
1868 partitioning. There are methods for logLik(), deviance(), and
1869 AIC(), and the summary() method has been extended to display in
1870 a friendly way the results of this model fitting. Currently, the
1871 functionality is limited to estimating the substitution and
1872 associated parameters and computing the likelihood.
1874 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1875 tests for single effects in GEE-based comparative method. A
1876 warning message is printed if there is not enough degrees of
1882 o An error message was sometimes issued by plot.multi.tree(),
1883 though with no consequence.
1887 CHANGES IN APE VERSION 1.8-1
1892 o There is a new plot method for lists of trees (objects of class
1893 "multi.tree"): it calls plot.phylo() internally and is
1894 documented on the same help page.
1899 o A bug was fixed in the C code that analyzes bipartitions: this
1900 has impact on several functions like prop.part, prop.clades,
1901 boot.phylo, or consensus.
1903 o root() did not work correctly when the specified outgroup had
1904 more than one element: this is fixed.
1906 o dist.dna() sometimes returned a warning inappropriately: this
1909 o If the distance object given to nj() had no rownames, nj()
1910 returned a tree with no tip labels: it now returns tips labelled
1911 "1", "2", ..., corresponding to the row numbers.
1916 o nj() has been slightly changed so that tips with a zero distance
1917 are first aggregated with zero-lengthed branches; the usual NJ
1918 procedure is then performed on a distance matrix without 0's.
1922 CHANGES IN APE VERSION 1.8
1927 o The new function chronopl() estimates dates using the penalized
1928 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1930 o The new function consensus() calculates the consensus tree of a
1933 o The new function evolve.phylo() simulates the evolution of
1934 continuous characters along a phylogeny under a Brownian model.
1936 o The new plot method for objects of class "ancestral" displays a
1937 tree together with ancestral values, as returned by the above
1940 o The new function as.phylo.formula() returns a phylogeny from a
1941 set of nested taxonomic variables given as a formula.
1943 o The new function read.caic() reads trees in CAIC format.
1945 o The new function tiplabels() allows to add labels to the tips
1946 of a tree using text or plotting symbols in a flexible way.
1948 o The new function unroot() unroots a phylogeny.
1950 o multi2di() has a new option, `random', which specifies whether
1951 to resolve the multichotomies randomly (the default) or not.
1953 o prop.part() now returns an object of class "prop.part" for which
1954 there are print (to display a partition in a more friendly way)
1955 and summary (to extract the numbers) methods.
1957 o plot.phylo() has a new option, `show.tip.label', specifying
1958 whether to print the labels of the tips. The default is TRUE.
1960 o The code of nj() has been replaced by a faster C code: it is now
1961 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1964 o write.nexus() now writes whether a tree is rooted or not.
1969 o Two bugs have been fixed in root(): unrooted trees are now
1970 handled corretly, and node labels are now output normally.
1972 o A bug was fixed in phymltest(): the executable couldn't be found
1975 o Three bug have been fixed in ace(): computing the likelihood of
1976 ancestral states of discrete characters failed, custom models
1977 did not work, and the function failed with a null gradient (a
1978 warning message is now returned; this latter bug was also
1979 present in yule.cov() as well and is now fixed).
1981 o pic() hanged out when missing data were present: a message error
1984 o A small bug was fixed in dist.dna() where the gamma correction
1985 was not always correctly dispatched.
1987 o plot.phylo() plotted correctly the root edge only when the tree
1988 was plotted rightwards: this works now for all directions.
1993 o dist.taxo() has been renamed as weight.taxo().
1995 o dist.phylo() has been replaced by the method cophenetic.phylo().
1997 o Various error and warning messages have been improved.
2001 CHANGES IN APE VERSION 1.7
2004 o The new function ace() estimates ancestral character states for
2005 continuous characters (with ML, GLS, and contrasts methods), and
2006 discrete characters (with ML only) for any number of states.
2008 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
2009 of directional evolution for continuous characters. The user
2010 specifies the node(s) of the tree where the character optimum
2013 o The new function is.rooted() tests whether a tree (of class
2016 o The new function rcoal() generates random ultrametric trees with
2017 the possibility to specify the function that generates the
2018 inter-nodes distances.
2020 o The new function mrca() gives for all pairs of tips in a tree
2021 (and optionally nodes too) the most recent common ancestor.
2023 o nodelabels() has a new option `thermo' to plot proportions (up
2024 to three classes) on the nodes of a tree.
2026 o rtree() has been improved: it can now generate rooted or
2027 unrooted trees, and the mathematical function that generates the
2028 branch lengths may be specified by the user. The tip labels may
2029 be given directly in the call to rtree. The limit cases (n = 2,
2030 3) are now handled correctly.
2032 o dist.topo() has a new argument `method' with two choices: "PH85"
2033 for Penny and Henny's method (already available before and now
2034 the default), and "BHV01" for the geometric distance by Billera
2035 et al. (2001, Adv. Appl. Math. 27:733).
2037 o write.tree() has a new option, `digits', which specifies the
2038 number of digits to be printed in the Newick tree. By default
2039 digits = 10. The numbers are now always printed in decimal form
2040 (i.e., 1.0e-1 is now avoided).
2042 o dist.dna() can now compute the raw distances between pairs of
2043 DNA sequences by specifying model = "raw".
2045 o dist.phylo() has a new option `full' to possibly compute the
2046 distances among all tips and nodes of the tree. The default if
2052 o Several bugs were fixed in all.equal.phylo().
2054 o dist.dna() did not handle correctly gaps ("-") in alignments:
2055 they are now considered as missing data.
2057 o rotate() did not work if the tips were not ordered: this is
2060 o mantel.test() returned NA in some special cases: this is fixed
2061 and the function has been improved and is now faster.
2063 o A bug was fixed in diversi.gof() where the calculation of A² was
2066 o cherry() did not work correctly under some OSs (mainly Linux):
2069 o is.binary.tree() has been modified so that it works with both
2070 rooted and unrooted trees.
2072 o The documentation of theta.s() was not correct: this has been
2075 o plot.mst() did not work correctly: this is fixed.
2079 CHANGES IN APE VERSION 1.6
2084 o The new function dist.topo() computes the topological distances
2087 o The new function boot.phylo() performs a bootstrap analysis on
2088 phylogeny estimation.
2090 o The new functions prop.part() and prop.clades() analyse
2091 bipartitions from a series of trees.
2096 o read.GenBank() now uses the EFetch utility of NCBI instead of
2097 the usual Web interface: it is now much faster (e.g., 12 times
2098 faster to retrieve 8 sequences, 37 times for 60 sequences).
2103 o Several bugs were fixed in read.dna().
2105 o Several bugs were fixed in diversi.time().
2107 o is.binary.tree() did not work correctly if the tree has no edge
2108 lengths: this is fixed.
2110 o drop.tip() did not correctly propagated the `node.label' of a
2111 tree: this is fixed.
2115 CHANGES IN APE VERSION 1.5
2120 o Two new functions, as.matching.phylo() and as.phylo.matching(),
2121 convert objects between the classes "phylo" and "matching". The
2122 latter implements the representation of binary trees introduced by
2123 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
2124 as.matching() has been introduced as well.
2126 o Two new functions, multi2di() and di2multi(), allow to resolve
2127 and collapse multichotomies with branches of length zero.
2129 o The new function nuc.div() computes the nucleotide diversity
2130 from a sample a DNA sequences.
2132 o dist.dna() has been completely rewritten with a much faster
2133 (particularly for large data sets) C code. Eight models are
2134 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
2135 option `method' has been renamed `model'). Computation of variance
2136 is available for all models. A gamma-correction is possible for
2137 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
2138 to remove sites with missing data on a pairwise basis. The option
2139 `GCcontent' has been removed.
2141 o read.GenBank() has a new option (species.names) which specifies
2142 whether to return the species names of the organisms in addition
2143 to the accession numbers of the sequences (this is the default
2146 o write.nexus() can now write several trees in the same NEXUS file.
2148 o drop.tip() has a new option `root.edge' that allows to specify the
2149 new root edge if internal branches are trimmed.
2154 o as.phylo.hclust() failed if some labels had parentheses: this
2157 o Several bugs were fixed in all.equal.phylo(). This function now
2158 returns the logical TRUE if the trees are identical but with
2159 different representations (a report was printed previously).
2161 o read.GenBank() did not correctly handle ambiguous base codes:
2167 o birthdeath() now returns an object of class "birthdeath" for
2168 which there is a print method.
2172 CHANGES IN APE VERSION 1.4
2177 o The new function nj() performs phylogeny estimation with the
2178 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
2181 o The new function which.edge() identifies the edges of a tree
2182 that belong to a group specified as a set of tips.
2184 o The new function as.phylo.phylog() converts an object of class
2185 "phylog" (from the package ade4) into an object of class
2188 o The new function axisPhylo() draws axes on the side of a
2191 o The new function howmanytrees() calculates the number of trees
2192 in different cases and giving a number of tips.
2194 o write.tree() has a new option `multi.line' (TRUE by default) to
2195 write a Newick tree on several lines rather than on a single
2198 o The functionalities of zoom() have been extended. Several
2199 subtrees can be visualized at the same time, and they are marked
2200 on the main tree with colors. The context of the subtrees can be
2201 marked with the option `subtree' (see below).
2203 o drop.tip() has a new option `subtree' (FALSE by default) which
2204 specifies whether to output in the tree how many tips have been
2207 o The arguments of add.scale.bar() have been redefined and have
2208 now default values (see ?add.scale.bar for details). This
2209 function now works even if the plotted tree has no edge length.
2211 o plot.phylo() can now plot radial trees, but this does not take
2212 edge lengths into account.
2214 o In plot.phylo() with `type = "phylogram"', if the values of
2215 `edge.color' and `edge.width' are identical for sister-branches,
2216 they are propagated to the vertical line that link them.
2221 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
2222 crashing. This is fixed.
2224 o In plot.phylo(), the options `edge.color' and `edge.width' are
2225 now properly recycled; their default values are now "black" and
2228 o A bug has been fixed in write.nexus().
2233 o The function node.depth.edgelength() has been removed and
2234 replaced by a C code.
2238 CHANGES IN APE VERSION 1.3-1
2243 o The new function nodelabels() allows to add labels to the nodes
2244 of a tree using text or plotting symbols in a flexible way.
2246 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
2247 numeric values specifying the lower and upper limits on the x-
2248 and y-axes. This allows to leave some space on any side of the
2249 tree. If a single value is given, this is taken as the upper
2254 CHANGES IN APE VERSION 1.3
2259 o The new function phymltest() calls the software PHYML and fits
2260 28 models of DNA sequence evolution. There are a print method to
2261 display likelihood and AIC values, a summary method to compute
2262 the hierarchical likelihood ratio tests, and a plot method to
2263 display graphically the AIC values of each model.
2265 o The new function yule.cov() fits the Yule model with covariates,
2266 a model where the speciation rate is affected by several species
2267 traits through a generalized linear model. The parameters are
2268 estimated by maximum likelihood.
2270 o Three new functions, corBrownian(), corGrafen(), and
2271 corMartins(), compute the expected correlation structures among
2272 species given a phylogeny under different models of evolution.
2273 These can be used for GLS comparative phylogenetic methods (see
2274 the examples). There are coef() and corMatrix() methods and an
2275 Initialize.corPhyl() function associated.
2277 o The new function compar.cheverud() implements Cheverud et al.'s
2278 (1985; Evolution 39:1335) phylogenetic comparative method.
2280 o The new function varcomp() estimates variance components; it has
2283 o Two new functions, panel.superpose.correlogram() and
2284 plot.correlogramList(), allow to plot several phylogenetic
2287 o The new function node.leafnumber() computes the number of leaves
2288 of a subtree defined by a particular node.
2290 o The new function node.sons() gets all tags of son nodes from a
2293 o The new function compute.brlen() computes the branch lengths of
2294 a tree according to a specified method.
2296 o plot.phylo() has three new options: "cex" controls the size of
2297 the (tip and node) labels (thus it is no more needed to change
2298 the global graphical parameter), "direction" which allows to
2299 plot the tree rightwards, leftwards, upwards, or downwards, and
2300 "y.lim" which sets the upper limit on the y-axis.
2305 o Some functions which try to match tip labels and names of
2306 additional data (e.g. vector) are likely to fail if there are
2307 typing or syntax errors. If both series of names do not perfectly
2308 match, they are ignored and a warning message is now issued.
2309 These functions are bd.ext, compar.gee, pic. Their help pages
2310 have been clarified on this point.
2314 CHANGES IN APE VERSION 1.2-7
2319 o The new function root() reroots a phylogenetic tree with respect
2320 to a specified outgroup.
2322 o The new function rotate() rotates an internal branch of a tree.
2324 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
2325 trees) controls the display of the tip labels in unrooted trees.
2326 This display has been greatly improved: the tip labels are now not
2327 expected to overlap with the tree (particularly if lab4ut =
2328 "axial"). In all cases, combining appropriate values of "lab4ut"
2329 and the font size (via "par(cex = )") should result in readable
2330 unrooted trees. See ?plot.phylo for some examples.
2332 o In drop.tip(), the argument `tip' can now be numeric or character.
2337 o drop.tip() did not work correctly with trees with no branch
2338 lengths: this is fixed.
2340 o A bug in plot.phylo(..., type = "unrooted") made some trees being
2341 plotted with some line crossings: this is now fixed.
2345 CHANGES IN APE VERSION 1.2-6
2350 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
2351 correlogram.phylo, dist.taxo, plot.correlogram) have been added
2352 to implement comparative methods with an autocorrelation approach.
2354 o A new data set describing some life history traits of Carnivores
2360 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
2365 o When plotting a tree with plot.phylo(), the new default of the
2366 option `label.offset' is now 0, so the labels are always visible.
2370 CHANGES IN APE VERSION 1.2-5
2375 o The new function bd.ext() fits a birth-death model with combined
2376 phylogenetic and taxonomic data, and estimates the corresponding
2377 speciation and extinction rates.
2382 o The package gee is no more required by ape but only suggested
2383 since only the function compar.gee() calls gee.
2387 CHANGES IN APE VERSION 1.2-4
2392 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
2393 and lines.popsize) implementing a new approach for inferring the
2394 demographic history from genealogies using a reversible jump
2395 MCMC have been introduced.
2397 o The unit of time in the skyline plot and in the new plots can
2398 now be chosen to be actual years, rather than substitutions.
2402 CHANGES IN APE VERSION 1.2-3
2407 o The new function rtree() generates a random binary tree with or
2408 without branch lengths.
2410 o Two new functions for drawing lineages-through-time (LTT) plots
2411 are provided: ltt.lines() adds a LTT curve to an existing plot,
2412 and mltt.plot() does a multiple LTT plot giving several trees as
2413 arguments (see `?ltt.plot' for details).
2418 o Some taxon names made R crashing when calling as.phylo.hclust():
2421 o dist.dna() returned an error with two identical DNA sequences
2422 (only using the Jukes-Cantor method returned 0): this is fixed.
2427 o The function dist.phylo() has been re-written using a different
2428 algorithm: it is now about four times faster.
2430 o The code of branching.times() has been improved: it is now about
2435 CHANGES IN APE VERSION 1.2-2
2440 o The new function seg.sites() finds the segregating sites in a
2441 sample of DNA sequences.
2446 o A bug introduced in read.tree() and in read.nexus() with version
2449 o A few errors were corrected and a few examples were added in the
2454 CHANGES IN APE VERSION 1.2-1
2459 o plot.phylo() can now draw the edge of the root of a tree if it
2460 has one (see the new option `root.edge', its default is FALSE).
2465 o A bug was fixed in read.nexus(): files with semicolons inside
2466 comment blocks were not read correctly.
2468 o The behaviour of read.tree() and read.nexus() was corrected so
2469 that tree files with badly represented root edges (e.g., with
2470 an extra pair of parentheses, see the help pages for details)
2471 are now correctly represented in the object of class "phylo";
2472 a warning message is now issued.
2476 CHANGES IN APE VERSION 1.2
2481 o plot.phylo() has been completely re-written and offers several
2482 new functionalities. Three types of trees can now be drawn:
2483 phylogram (as previously), cladogram, and unrooted tree; in
2484 all three types the branch lengths can be drawn using the edge
2485 lengths of the phylogeny or not (e.g., if the latter is absent).
2486 The vertical position of the nodes can be adjusted with two
2487 choices (see option `node.pos'). The code has been re-structured,
2488 and two new functions (potentially useful for developpers) are
2489 documented separately: node.depth.edgelength() and node.depth();
2490 see the respective help pages for details.
2492 o The new function zoom() allows to explore very large trees by
2493 focusing on a small portion of it.
2495 o The new function yule() fits by maximum likelihood the Yule model
2496 (birth-only process) to a phylogenetic tree.
2498 o Support for writing DNA sequences in FASTA format has been
2499 introduced in write.dna() (support for reading sequences in
2500 this format was introduced in read.dna() in version 1.1-2).
2501 The function has been completely re-written, fixing some bugs
2502 (see below); the default behaviour is no more to display the
2503 sequences on the standard output. Several options have been
2504 introduced to control the sequence printing in a flexible
2505 way. The help page has been extended.
2507 o A new data set is included: a supertree of bats in NEXUS format.
2512 o In theta.s(), the default of the option `variance' has
2513 been changed to `FALSE' (as was indicated in the help page).
2515 o Several bugs were fixed in the code of all.equal.phylo().
2517 o Several bugs were fixed in write.dna(), particularly this
2518 function did not work with `format = "interleaved"'.
2520 o Various errors were corrected in the help pages.
2525 o The argument names of as.hclust.phylo() have been changed
2526 from "(phy)" to "(x, ...)" to conform to the definition of
2527 the corresponding generic function.
2529 o gamma.stat() has been renamed gammaStat() to avoid confusion
2530 since gamma() is a generic function.
2534 CHANGES IN APE VERSION 1.1-3
2539 o base.freq() previously did not return a value of 0 for
2540 bases absent in the data (e.g., a vector of length 3 was
2541 returned if one base was absent). This is now fixed (a
2542 vector of length 4 is always returned).
2544 o Several bugs were fixed in read.nexus(), including that this
2545 function did not work in this absence of a "TRANSLATE"
2546 command in the NEXUS file, and that the commands were
2551 CHANGES IN APE VERSION 1.1-2
2556 o The Tamura and Nei (1993) model of DNA distance is now implemented
2557 in dist.dna(): five models are now available in this function.
2559 o A new data set is included: a set of 15 sequences of the
2560 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2566 o A bug in read.nexus() was fixed.
2568 o read.dna() previously did not work correctly in most cases.
2569 The function has been completely re-written and its help page
2570 has been considerably extended (see ?read.dna for details).
2571 Underscores (_) in taxon names are no more replaced with
2572 spaces (this behaviour was undocumented).
2574 o A bug was fixed in write.dna().
2578 CHANGES IN APE VERSION 1.1-1
2583 o A bug in read.tree() introduced in APE 1.1 was fixed.
2585 o A bug in compar.gee() resulted in an error when trying to fit
2586 a model with `family = "binomial"'. This is now fixed.
2590 CHANGES IN APE VERSION 1.1
2595 o The Klastorin (1982) method as suggested by Misawa and Tajima
2596 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2597 on the basis of phylogenetic trees has been implemented (see
2598 the function klastorin()).
2600 o Functions have been added to convert APE's "phylo" objects in
2601 "hclust" cluster objects and vice versa (see the help page of
2602 as.phylo for details).
2604 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2605 are introduced for the estimation of absolute evolutionary rates
2606 (ratogram) and dated clock-like trees (chronogram) from
2607 phylogenetic trees using the non-parametric rate smoothing approach
2608 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2610 o A summary method is now provided printing a summary information on a
2611 phylogenetic tree with, for instance, `summary(tree)'.
2613 o The behaviour of read.tree() was changed so that all spaces and
2614 tabulations in tree files are now ignored. Consequently, spaces in tip
2615 labels are no more allowed. Another side effect is that read.nexus()
2616 now does not replace the underscores (_) in tip labels with spaces
2617 (this behaviour was undocumented).
2619 o The function plot.phylo() has a new option (`underscore') which
2620 specifies whether the underscores in tip labels should be written on
2621 the plot as such or replaced with spaces (the default).
2623 o The function birthdeath() now computes 95% confidence intervals of
2624 the estimated parameters using profile likelihood.
2626 o Three new data sets are included: a gene tree estimated from 36
2627 landplant rbcL sequences, a gene tree estimated from 32 opsin
2628 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2633 o A bug was fixed in dist.gene() where nothing was returned.
2635 o A bug in plot.mst() was fixed.
2637 o A bug in vcv.phylo() resulted in false correlations when the
2638 option `cor = TRUE' was used (now fixed).
2642 CHANGES IN APE VERSION 1.0
2647 o Two new functions, read.dna() and write.dna(), read/write in a file
2648 DNA sequences in interleaved or in sequential format.
2650 o Two new functions, read.nexus() and write.nexus(), read/write trees
2653 o The new function bind.tree() allows to bind two trees together,
2654 possibly handling root edges to give internal branches.
2656 o The new function drop.tip() removes the tips in a phylogenetic tree,
2657 and trims (or not) the corresponding internal branches.
2659 o The new function is.ultrametric() tests if a tree is ultrametric.
2661 o The function plot.phylo() has more functionalities such as drawing the
2662 branches with different colours and/or different widths, showing the
2663 node labels, controling the position and font of the labels, rotating
2664 the labels, and controling the space around the plot.
2666 o The function read.tree() can now read trees with no branch length,
2667 such as "(a,b),c);". Consequently, the element `edge.length' in
2668 objects of class "phylo" is now optional.
2670 o The function write.tree() has a new default behaviour: if the default
2671 for the option `file' is used (i.e. file = ""), then a variable of
2672 mode character containing the tree in Newick format is returned which
2673 can thus be assigned (e.g., tree <- write.tree(phy)).
2675 o The function read.tree() has a new argument `text' which allows
2676 to read the tree in a variable of mode character.
2678 o A new data set is included: the phylogenetic relationships among
2679 the orders of birds from Sibley and Ahlquist (1990).
2683 CHANGES IN APE VERSION 0.2-1
2688 o Several bugs were fixed in the help pages.
2692 CHANGES IN APE VERSION 0.2
2697 o The function write.tree() writes phylogenetic trees (objects of class
2698 "phylo") in an ASCII file using the Newick parenthetic format.
2700 o The function birthdeath() fits a birth-death model to branching times
2701 by maximum likelihood, and estimates the corresponding speciation and
2704 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2707 o The function is.binary.tree() tests whether a phylogeny is binary.
2709 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2710 as well as some methods are introduced.
2712 o Several functions, including some generics and methods, for computing
2713 skyline plot estimates (classic and generalized) of effective
2714 population size through time are introduced and replace the function
2715 skyline.plot() in version 0.1.
2717 o Two data sets are now included: the phylogenetic relationships among
2718 the families of birds from Sibley and Ahlquist (1990), and an
2719 estimated clock-like phylogeny of HIV sequences sampled in the
2720 Democratic Republic of Congo.
2723 DEPRECATED & DEFUNCT
2725 o The function skyline.plot() in ape 0.1 has been deprecated and
2726 replaced by more elaborate functions (see above).
2731 o Two important bugs were fixed in plot.phylo(): phylogenies with
2732 multichotomies not at the root or not with only terminal branches,
2733 and phylogenies with a single node (i.e. only terminal branches)
2734 did not plot. These trees should be plotted correctly now.
2736 o Several bugs were fixed in diversi.time() in the computation of
2739 o Various errors were corrected in the help pages.
