1 CHANGES IN APE VERSION 3.0-7
6 o The new function 'where' searches patterns in DNA sequences.
8 o pic() gains an option 'rescaled.tree = FALSE' to return the tree
9 with its branch lengths rescaled for the PICs calculation.
14 o drop.tip() shuffled node labels on some trees.
18 CHANGES IN APE VERSION 3.0-6
23 o reorder.phylo() has a new order, "postorder", and a new option
24 index.only = TRUE to return only the vector of indices (the tree
25 is unmodified, see ?reorder.phylo for details).
27 o The three new functions node.depth.edgelength, node.height, and
28 node.height.clado make some internal code available from R. See
29 ?node.depth (which was already documented) for details.
34 o reorder(, "pruningwise") made R crash if the rows of the edge
35 matrix are in random order: this is now fixed.
37 o drop.tip() sometimes shuffled node labels (thanks to Rebecca
40 o drop.tip(phy, "") returned a tree with zero-length tip labels:
41 it now returns the tree unchanged (thanks to Brian Anacker for
44 o plot.phylo() made R crash if the tree has zero-length tip
45 labels: it now returns NULL (thanks again to Brian Anacker).
50 o dist.nodes() is now 6 to 10 times faster.
52 o reorder(, "cladewise") is now faster. The change is not very
53 visible for small trees (n < 1000) but this can be more than
54 1000 faster for big trees (n >= 1e4).
56 o The attribute "order" of the objects of class "phylo" is now
57 strongly recommended, though not mandatory. Most functions in
58 ape should return a tree with this attribute correctly set.
60 o dbd() is now vectorized on both arguments 'x' (number of species
61 in clade) and 't' (clade age) to make likelihood calculations
66 CHANGES IN APE VERSION 3.0-5
71 o ace() should better catch errors when SEs cannot be computed.
76 o write.dna(format = "fasta") now conforms more closely to the
77 FASTA standard thanks to François Michonneau.
79 o print.DNAbin() does not print base compositions if there are more
80 than one million nucleotides.
84 CHANGES IN APE VERSION 3.0-4
89 o read.dna() failed to read Phylip files if the first line used
90 tabulations instead of white spaces.
92 o read.dna() failed to read Phylip or Clustal files with less than
93 10 nucleotides. (See other changes in this function below.)
97 o read.dna() now requires at least one space (or tab) between the
98 taxa names and the sequences (whatever the length of taxa
99 names). write.dna() now follows the same rule.
101 o The option 'seq.names' of read.dna has been removed.
103 o The files ape-defunct.R and ape-defunct.Rd, which have not been
104 modified for almost two years, have been removed.
106 o The C code of bionj() has been reworked: it is more stable (by
107 avoiding passing character strings), slightly faster (by about
108 20%), and numerically more accurate.
110 o The C code of fastme.*() has been slightly modified and should
111 be more stable by avoiding passing character strings (the
112 results are identical to the previous versions).
114 o The file src/newick.c has been removed.
118 CHANGES IN APE VERSION 3.0-3
123 o birthdeath() now catches errors and warnings much better so that
124 a result is returned in most cases.
129 o Because of problems with character string manipulation in C, the
130 examples in ?bionj and in ?fastme have been disallowed. In the
131 meantime, these functions might be unstable. This will be solved
132 for the next release.
136 CHANGES IN APE VERSION 3.0-2
141 o The new function alex (alignment explorator) zooms in a DNA
142 alignment and opens the result in a new window.
147 o compute.brtime() did not completely randomized the order of the
150 o write.nexus() did not work correctly with rooted trees (thanks
151 to Matt Johnson for the fix).
153 o mltt.plot(, backward = FALSE) did not set the x-axis correctly.
155 o A bug was introduced in prop.clades() with ape 3.0. The help page
156 has been clarified relative to the use of the option 'rooted'.
158 o mantel.test() printed a useless warning message.
160 o plot.phylo(, direction = "downward") ignored 'y.lim'.
162 o is.monophyletic() did not work correctly if 'tips' was not stored
165 o prop.part() could make R crash if the first tree had many
168 o njs(), bionjs(), and mvrs() now return an error if 'fs < 1'.
170 o SDM() did not work correctly. The code has also been generally
176 o The DESCRIPTION file has been updated.
178 o The option 'original.data' of write.nexus() has been removed.
180 o The files bionjs.c, mvr.c, mvrs.c, njs.c, triangMtd.c, and
181 triangMtds.c have been improved which should fix some bugs in
182 the corresponding functions.
184 o dist.gene() now coerces input data frame as matrix resulting in
185 much faster calculations (thanks to a suggestion by Markus
190 CHANGES IN APE VERSION 3.0-1
195 o dist.dna() has two new models: "indel" and "indelblock".
197 o bind.tree() now accepts 'position' > 0 when the trees have no
198 banch length permitting to create a node in 'x' when grafting
199 'y' (see ?bind.tree for details).
204 o cophyloplot( , rotate = TRUE) made R hanged after a few clicks.
205 Also the tree is no more plotted twice.
207 o read.GenBank() has been updated to work with EFetch 2.0.
209 o unroot() on trees in "pruningwise" order did not respect this
214 CHANGES IN APE VERSION 3.0
219 o The three functions dyule, dbd, and dbdTime calculate the
220 density probability (i.e., the distribution of the number of
221 species) for the Yule, the constant and the time-dependent
222 birth-beath models, respectively. These probabilities can be
223 conditional on no extinction and/or on a log-scale.
225 o plot.phylo() has a new option 'rotate.tree' to rotate unrooted,
226 fan, or radial trees around the center of the plot.
228 o boot.phylo() and prop.clades() have a new option rooted =
229 FALSE. Note that the behaviour of prop.part() is unchanged.
231 o edgelabels() has a new option 'date' to place labels on edges of
232 chronograms using the time scale (suggestion by Rob Lanfear).
237 o In chronopl(), the code setting the initial dates failed in
238 complicated settings (several dates known within intervals).
239 This has been generally improved and should result in faster
240 and more efficient convergence even in simple settings.
242 o mantel.test() sometimes returned P-values > 1 with the default
245 o extract.clade() sometimes shuffled some tip labels (thanks to
246 Ludovic Mallet and Mahendra Mariadassou for the fix).
248 o clustal() should now find by default the executable under Windows.
253 o The code of yule() has been simplified and is now much faster for
256 o The code of mantel.test() has been adjusted to be consistent
257 with common permutation tests.
259 o The C code of base.freq() has been improved and is now nearly 8
262 o The option 'original.data' of write.nexus() is now deprecated and
263 will be removed in a future release.
265 o The code of is.ultrametric() has been improved and is now 3 times
268 o The code of vcv.phylo() has been improved and is now 10 or 30
269 times faster for 100 or 1000 tips, respectively. Consequently,
270 fitting models with PGLS will be faster overall.
274 CHANGES IN APE VERSION 2.8
279 o Twelve new functions have been written by Andrei-Alin Popescu:
280 additive, ultrametric, is.compatible, arecompatible, mvr, mvrs,
281 njs, bionjs, SDM, treePop, triangMtd, triangMtd*.
283 o A new class "bitsplits" has been created by Andrei-Alin Popescu
284 to code splits (aka, bipartition).
286 o There is a new generic function as.bitsplits with a method to
287 convert from the class "prop.part" to the class "bitsplits".
289 o The new function ltt.coplot plots on the same scales a tree and
290 the derived LTT plot.
292 o ltt.plot() has two new options: backward and tol. It can now
293 handle non-ultrametic trees and its internal coding has been
294 improved. The coordinates of the plot can now be computed with
295 the new function ltt.plot.coords.
300 o prop.part() crashed if some trees had some multichotomies.
304 CHANGES IN APE VERSION 2.7-3
309 o The new function compute.brtime computes and sets branching times.
311 o mantel.test() has a new argument 'alternative' which is
312 "two-sided" by default. Previously, this test was one-tailed
313 with no possibility to change.
315 o ace() can now do REML estimation with continuous characters,
316 giving better estimates of the variance of the Brownian motion
322 o Branch lengths were wrongly updated with bind.tree(, where = <tip>,
323 position = 0). (Thanks to Liam Revell for digging this bug out.)
325 o Simulation of OU process with rTraitCont() did not work correctly.
326 This now uses formula from Gillespie (1996) reduced to a BM
327 process when alpha = 0 to avoid division by zero. The option
328 'linear' has been removed.
330 o Cross-validation in chronopl() did not work when 'age.max' was
333 o consensus(, p = 0.5) could return an incorrect tree if some
334 incompatible splits occur in 50% of the trees (especially with
335 small number of trees).
337 o c() with "multiPhylo" did not work correctly (thanks to Klaus
338 Schliep for the fix).
340 o root() failed in some cases with an outgroup made of several tips.
341 The help page has been clarified a bit.
345 CHANGES IN APE VERSION 2.7-2
350 o There is a new class "evonet" to code evolutionary networks, with
351 a constructor function evonet(), a print() and a plot() methods,
352 and four conversion methods to the classes "phylo", "networx",
353 "network", and "igraph".
355 o The new function rTraitMult does multivariate traits simulation
356 with user-defined models.
358 o plot.phylo() has a new option 'plot = TRUE'. If FALSE, the tree
359 is not plotted but the graphical device is set and the
360 coordinates are saved as usual.
362 o diversity.contrast.test() gains a fourth version of the test with
363 method = "logratio"; the literature citations have been clarified.
365 o add.scale.bar() has two new options, 'lwd' and 'lcol', to modify
366 the aspect of the bar.
368 o boot.phylo() now displays a progress bar by default (can be off
371 o There is a new predict() method for compar.gee().
376 o bionj() made R crash if distances were too large. It now returns
377 an error if at least one distance is greater than 100.
379 o drop.tip() returned a wrong tree if 'tip' was of zero length.
381 o read.nexus.data() failed with URLs.
383 o boot.phylo() returned overestimated support values in the
384 presence of identical or nearly identical sequences.
389 o The data bird.families, bird.orders, cynipids, and woodmouse are
390 now provided as .rda files.
394 CHANGES IN APE VERSION 2.7-1

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

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

475 o BaseProportion in src/dist_dna.c has been modified.
477 o A number of functions in src/tree_build.c have been modified.
479 o The matching representation has now only two columns as the third
480 column was redundant.
484 CHANGES IN APE VERSION 2.6-3
489 o rTraitCont() and rTraitDisc() gains a '...' argument used with
490 user-defined models (suggestion by Gene Hunt).
495 o as.hclust.phylo() now returns an error with unrooted trees.
497 o as.hclust.phylo() failed with trees with node labels (thanks to
498 Jinlong Zhang for pointing this bug out).
500 o read.dna(, "fasta") failed if sequences were not all of the same
503 o plot.phylo() did not recycle values of 'font', 'cex' and
504 'tip.color' correctly when type = "fan" or "radial".
506 o plot.phylo() ignored 'label.offset' when type = "radial", "fan", or
507 "unrooted" with lab4ut = "axial" (the placement of tip labels still
508 needs to be improved with lab4ut = "horizontal").
513 o In drop.fossil() the default tol = 0 has been raised to 1e-8.
515 o The help command ?phylo now points to the man page of read.tree()
516 where this class is described. Similarly, ?matching points to the
517 man page of as.matching().
521 CHANGES IN APE VERSION 2.6-2
526 o Two new functions, pic.ortho and varCompPhylip, implements the
527 orthonormal contrasts of Felsenstein (2008, Am Nat, 171:713). The
528 second function requires Phylip to be installed on the computer.
530 o bd.ext() has a new option conditional = TRUE to use probabilities
531 conditioned on no extinction for the taxonomic data.
536 o write.tree() failed to output correctly tree names.
538 o dist.nodes() returned duplicated column(s) with unrooted and/or
539 multichotomous trees.
541 o mcmc.popsize() terminated unexpectedly if the progress bar was
544 o prop.part(x) made R frozen if 'x' is of class "multiPhylo".
546 o Compilation under Mandriva failed (thanks to Jos Käfer for the fix).
548 o drop.tip() shuffled tip labels with subtree = TRUE or trim.internal
551 o Objects returned by as.hclust.phylo() failed when analysed with
552 cutree() or rect.hclust().
554 o write.tree() did not output correctly node labels (thanks to Naim
555 Matasci and Jeremy Beaulieu for the fix).
557 o ace(type = "discrete") has been improved thanks to Naim Marasci and
562 CHANGES IN APE VERSION 2.6-1
567 o The new function speciesTree calculates the species tree from a set
568 of gene trees. Several methods are available including maximum tree
569 and shallowest divergence tree.

576 o as.list.DNAbin() did not work correctly with vectors.
578 o as.hclust.phylo() failed with trees with node labels (thanks to
579 Filipe Vieira for the fix).
583 CHANGES IN APE VERSION 2.6
588 o The new functions rlineage and rbdtree simulate phylogenies under
589 any user-defined time-dependent speciation-extinction model. They
590 use continuous time algorithms.
592 o The new function drop.fossil removes the extinct species from a
595 o The new function bd.time fits a user-defined time-dependent
596 birth-death model. It is a generalization of yule.time() taking
597 extinction into account.
599 o The new function MPR does most parsimonious reconstruction of
602 o The new function Ftab computes the contingency table of base
603 frequencies from a pair of sequences.
605 o There is now an 'as.list' method for the class "DNAbin".
607 o dist.dna() can compute the number of transitions or transversions
608 with the option model = "Ts" or model = "Tv", respectively.
610 o [node|tip|edge]labels() gain three options with default values to
611 control the aspect of thermometers: horiz = TRUE, width = NULL,
614 o compar.gee() has been improved with the new option 'corStruct' as an
615 alternative to 'phy' to specify the correlation structure, and
616 calculation of the QIC (Pan 2001, Biometrics). The display of the
617 results has also been improved.
619 o read.GenBank() has a new option 'gene.names' to return the name of
620 the gene (FALSE by default).
625 o extract.clade() sometimes shuffled the tip labels.
627 o plot.phylo(type = "unrooted") did not force asp = 1 (thanks to Klaus
630 o dist.dna(model = "logdet") used to divide distances by 4. The
631 documentation has been clarified on the formulae used.
636 o rTraitCont(model = "OU") has an option 'linear = TRUE' to possibly
637 change the parameterisation (see ?rTraitCont for details).
639 o pic() now returns a vector with the node labels of the tree (if
642 o write.tree() and read.tree() have been substantially improved thanks
643 to contributions by Klaus Schliep.
647 CHANGES IN APE VERSION 2.5-3
652 o The new function mixedFontLabel helps to make labels with bits of
653 text to be plotted in different fonts.
655 o There are now replacement operators for [, [[, and $ for the class
656 "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They possibly
657 check that the tip labels are the same in all trees.
659 o Objects of class "multiPhylo" can be built with c(): there are
660 methods for the classes "phylo" and "multiPhylo".
662 o The internal functions .compressTipLabel and .uncompressTipLabel are
668 o bind.tree(x, y, where, position = 0) did not work correctly if 'y'
669 was a single-edge tree and 'where' was a tip.
671 o rTraitCont() did not use the square-root of branch lengths when
672 simulating a Brownian motion model.
676 CHANGES IN APE VERSION 2.5-2

728 o drop.tip(), extract.clade(), root(), and bind.tree() now have an
729 'interactive' option to make the operation on a plotted tree.
731 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
732 association links; they are recycled like 'col' (which wasn't before).
737 o rTraitDisc() did not use its 'freq' argument correctly (it was
738 multiplied with the rate matrix column-wise instead of row-wise).
740 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
741 with NA values. Nothing is drawn now like with 'text' or 'pch'.
742 The same bug occurred with the 'pie' option.
744 o A bug was fixed in compar.ou() and the help page was clarified.
746 o bind.tree() has been rewritten fixing several bugs and making it
749 o plot.phylo(type = "p") sometimes failed to colour correctly the
750 vertical lines representing the nodes.
752 o plot.phylo(direction = "l", x.lim = 30) failed to plot the branches
753 in the correct direction though the tip labels were displayed
759 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
760 the sequences are correctly stored (in a list for c, in a matrix
761 for the two other functions).
765 CHANGES IN APE VERSION 2.5
770 o The new function parafit by Pierre Legendre tests for the
771 coevolution between hosts and parasites. It has a companion
772 function, pcoa, that does principal coordinate decomposition.
773 The latter has a biplot method.
775 o The new function lmorigin by Pierre Legendre performs multiple
776 regression through the origin with testing by permutation.
778 o The new functions rTraitCont and rTraitDisc simulate continuous and
779 discrete traits under a wide range of evolutionary models.
781 o The new function delta.plot does a delta plot following Holland et
782 al. (2002, Mol. Biol. Evol. 12:2051).
784 o The new function edges draws additional branches between any nodes
785 and/or tips on a plotted tree.
787 o The new function fancyarrows enhances arrows from graphics with
788 triangle and harpoon heads; it can be called from edges().
790 o add.scale.bar() has a new option 'ask' to draw interactively.
792 o The branch length score replaces the geodesic distance in dist.topo.
794 o Three new data sets are included: the gopher-lice data (gopher.D),
795 SO2 air pollution in 41 US cities (lmorigin.ex1, from Sokal &
796 Rohlf 1995), and some host-parasite specificity data
797 (lmorigin.ex2, from Legendre & Desdevises 2009).
802 o add.scale.bar() drew the bar outside the plotting region with the
803 default options with unrooted or radial trees.
805 o dist.topo() made R stuck when the trees had different sizes (thanks
806 to Otto Cordero for the fix).
811 o The geodesic distance has been replaced by the branch length score
816 CHANGES IN APE VERSION 2.4-1
821 o rtree() and rcoal() now accept a numeric vector for the 'br'
824 o vcv() is a new generic function with methods for the classes "phylo"
825 and "corPhyl" so that it is possible to calculate the var-cov matrix
826 for "transformation models". vcv.phylo() can still be used for trees
827 of class "phylo"; its argument 'cor' has been renamed 'corr'.
832 o bind.tree() failed when 'y' had no root edge.
834 o read.nexus() shuffled tip labels when the trees have no branch
835 lengths and there is a TRANSLATE block.
837 o read.nexus() does not try to translate node labels if there is a
838 translation table in the NEXUS file. See ?read.nexus for a
839 clarification on this behaviour.
841 o plot.multiPhylo() crashed R when plotting a list of trees with
842 compressed tip labels.
844 o write.nexus() did not translate the taxa names when asked for.
846 o plot.phylo(type = "fan") did not rotate the tip labels correctly
847 when the tree has branch lengths.
849 o ace(type = "continuous", method = "ML") now avoids sigma² being
850 negative (which resulted in an error).
852 o nj() crashed with NA/NaN in the distance matrix: an error in now
857 CHANGES IN APE VERSION 2.4
862 o base.freq() has a new option 'freq' to return the counts; the
863 default is still to return the proportions.
868 o seg.sites() did not handle ambiguous nucleotides correctly: they
871 o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
872 the tree: the argument is now ignored.
874 o add.scale.bar() failed when 'x' and 'y' were given (thanks to Janet
880 o Trying to plot a tree with a single tip now returns NULL with a
881 warning (it returned an error previously).
883 o The way lines representing nodes are coloured in phylograms has
884 been modified (as well as their widths and types) following some
885 users' request; this is only for dichotomous nodes.
887 o The argument 'adj' in [node][tip][edge]labels() now works when
888 using 'pie' or 'thermo'.
890 o A more informative message error is now returned by dist.dna() when
891 'model' is badly specified (partial matching of this argument is
894 o Deprecated functions are now listed in a help page: see
895 help("ape-defunct") with the quotes.
900 o The functions heterozygosity, nuc.div, theta.h, theta.k and
901 theta.s have been moved from ape to pegas.
903 o The functions mlphylo, DNAmodel and sh.test have been removed.
907 CHANGES IN APE VERSION 2.3-3

928 o root() shuffled node labels with 'resolve.root = TRUE'.
932 CHANGES IN APE VERSION 2.3-2
937 o all.equal.phylo() did not compare unrooted trees correctly.
939 o dist.topo(... method = "PH85") did not treat unrooted trees
940 correctly (thanks to Tim Wallstrom for the fix).

945 o extract.clade() sometimes included too many edges.
947 o vcv.phylo() did not work correctly when the tree is in
950 o nj() did not handle correctly distance matrices with many 0's.

969 to be treated as (un)rooted.
974 o dist.gene() failed on most occasions with the default
975 pairwise.deletion = FALSE.

986 the fix. With other improvements, this function is now about 6
989 o write.tree() failed with objects of class "multiPhylo".
991 o drop.tip(, subtree = TRUE) sometimes shuffled tip labels.
996 o [.multiPhylo and [.DNAbin now respect the original class.

1053 CHANGES IN APE VERSION 2.2-4
1057 o The bug fix in read.nexus() in version 2.2-3 was wrong: this is
1058 now fixed. (Thanks to Peter Wragg for the fix!)
1060 o A warning message occurred for no reason with ace(method="GLS").
1065 o There is now a general help page displayed with '?ape'.

1093 the number of lineages with non-binary trees.
1098 o ape has now a namespace.
1100 o drop.tip() has been improved: it should be much faster and work
1101 better in some cases (e.g., see the example in ?zoom).
1105 CHANGES IN APE VERSION 2.2-2
1110 o dist.gene() has been substantially improved and gains an option
1111 'pairwise.deletion'.
1113 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
1119 o prop.part() failed with a single tree with the default option
1120 'check.labels = TRUE'.
1122 o summary.DNAbin() failed to display correctly the summary of
1123 sequence lengths with lists of sequences of 10,000 bases or more
1124 (because summary.default uses 4 significant digits by default).
1126 o read.nexus() failed to read a file with a single tree with line
1127 breaks in the Newick string.
1129 o del.gaps() returned a list of empty sequences when there were no
1135 o phymltest() has been updated for PhyML 3.0 and gains an option
1136 'append', whereas the option 'path2exec' has been removed.
1138 o rbind.DNAbin() and cbind.DNAbin() now accept a single matrix
1139 which is returned unchanged (instead of an error).
1141 o The data sets bird.orders and bird.families are now stored as
1142 Newick strings; i.e., the command data(bird.orders) calls
1147 CHANGES IN APE VERSION 2.2-1
1152 o The new function makeLabel() helps to modify labels of trees,
1153 lists of trees, or DNA sequences, with several utilities to
1154 truncate and/or make them unique, substituting some
1155 characters, and so on.
1157 o The new function del.gaps() removes insertion gaps ("-") in a
1158 set of DNA sequences.
1160 o read.dna() can now read Clustal files (*.aln).

1166 already the specified root.
1168 o Several bugs were fixed in mlphylo().
1170 o collapsed.singles() did not propagate the 'Nnode' and
1171 'node.labels' elements (thanks to Elizabeth Purdom for the fix).

1270 (FALSE by default) as well as its code being improved.
1272 o mltt.plot() has now an option 'log' used in the same way
1273 than in plot.default().
1278 o mltt.plot() failed to display the legend with an unnamed
1281 o nodelabels() with pies now correcly uses the argument
1282 'cex' to draw symbols of different sizes (which has
1283 worked already for thermometers).
1285 o read.nexus() generally failed to read very big files.
1290 o The argument 'family' of compar.gee() can now be a function
1291 as well as a character string.
1293 o read.tree() and read.nexus() now return an unnamed list if
1294 'tree.names = NULL'.
1296 o read.nexus() now returns a modified object of class "multiPhylo"
1297 when there is a TRANSLATE block in the NEXUS file: the individual
1298 trees have no 'tip.label' vector, but the list has a 'TipLabel'
1299 attribute. The new methods '$' and '[[' set these elements
1300 correctly when extracting trees.
1304 CHANGES IN APE VERSION 2.1-1
1309 o The new function rmtree generates lists of random trees.
1311 o rcoal() now generates a genuine coalescent tree by default

1342 o The new function as.DNAbin.alignment converts DNA sequences
1343 stored in the "alignment" format of the package seqinr into
1344 an object of class "DNAbin".
1346 o The new function weight.taxo2 helps to build similarity matrices
1347 given two taxonomic levels (usually called by other functions).

1350 as its main argument.
1352 o plot.correlogram() and plot.correlogramList() have been
1353 improved, and gain several options (see the help page for
1354 details). A legend is now plotted by default.
1359 o dist.dna() returned some incorrect values with `model = "JC69"'
1360 and `pairwise.deletion = TRUE'. This affected only the
1361 distances involving sequences with missing values. (Thanks
1362 to Bruno Toupance for digging this bug out.)
1364 o write.tree() failed with some trees: this is fixed by removing
1365 the `multi.line' option (trees are now always printed on a
1368 o read.nexus() did not correctly detect trees with multiple root
1369 edges (see OTHER CHANGES).
1374 o The code of mlphylo() has been almost entirely rewritten, and
1375 should be much stabler. The options have been also greatly
1376 simplified (see ?mlphylo and ?DNAmodel for details).
1378 o The internal function nTips has been renamed klastorin_nTips.
1380 o The code of is.ultrametric() contained redundancies and has
1383 o The code of Moran.I() and of correlogram.formula() have been
1386 o read.tree() and read.nexus() now return an error when trying to

1417 o The new function unique.multi.tree removes duplicate trees from
1420 o yule() has a new option `use.root.edge = FALSE' that specifies
1421 to ignore, by default, the root edge of the tree if it exists.
1426 o which.edge() failed when the index of a single terminal edge was
1429 o In diversi.time(), the values returned for model C were
1432 o A bug was fixed in yule() that affected the calculation of the
1433 likelihood in the presence of ties in the branching times.
1435 o There was a bug in the C function mat_expo4x4 affecting the
1436 calculations of the transition probabilities for models HKY and
1439 o A small bug was fixed in as.matrix.DNAbin (thanks to James
1442 o rtree() did not `shuffle' the tip labels by default, so only a
1443 limited number of labelled topologies could be generated.
1447 CHANGES IN APE VERSION 2.0-1
1452 o The three new functions bionj, fastme.ols, and fastme.bal
1453 perform phylogeny estimation by the BIONJ and fastME methods in
1454 OLS and balanced versions. This is a port to R of previous
1455 previous programs done by Vincent Lefort.
1457 o The new function chronoMPL performs molecular dating with the
1458 mean path lengths method of Britton et al. (2002, Mol. Phyl.
1461 o The new function rotate, contributed by Christoph Heibl, swaps
1462 two clades connected to the same node. It works also with
1463 multichotomous nodes.
1465 o The new `method' as.matrix.DNAbin() may be used to convert
1466 easily DNA sequences stored in a list into a matrix while
1467 keeping the names and the class.
1472 o chronopl() failed when some branch lengths were equal to zero:
1473 an error message is now returned.
1475 o di2multi() failed when there was a series of consecutive edges
1480 CHANGES IN APE VERSION 1.10-2
1485 o plot.phylo() can now plot circular trees: the option is type =
1486 "fan" or type = "f" (to avoid the ambiguity with type = "c").
1488 o prop.part() has a new option `check.labels = FALSE' which allows
1489 to considerably speed-up the calculations of bipartitions. As a
1490 consequence, calculations of bootstrap values with boot.phylo()
1491 should be much faster.
1496 o read.GenBank() did not return correctly the list of species as
1497 from ape 1.10: this is fixed in this version
1499 o Applying as.phylo() on a tree of class "phylo" failed: the
1500 object is now returned unchanged.

1516 object when reading multiple trees.
1518 o mllt.plot() failed with objects of class c("multi.tree",
1521 o unroot() did not work correctly in most cases.
1523 o reorder.phylo() made R freeze in some occasions.

1528 correctly positioned if the option `cex' was used.
1532 CHANGES IN APE VERSION 1.10
1537 o Five new `method' functions have been introduced to manipulate
1538 DNA sequences in binary format (see below).
1540 o Three new functions have been introduced to convert between the
1541 new binary and the character formats.
1543 o The new function as.alignment converts DNA sequences stored as
1544 single characters into the class "alignment" used by the package
1547 o read.dna() and read.GenBank() have a new argument `as.character'
1548 controlling whether the sequences are returned in binary format
1554 o root() failed when the tree had node labels: this is fixed.
1556 o plot.phylo() did not correctly set the limits on the y-axis with
1557 the default setting: this is fixed.
1559 o dist.dna() returned a wrong result for the LogDet, paralinear,
1560 and BH87 models with `pairwise.deletion = TRUE'.
1565 o DNA sequences are now internally stored in a binary format. See
1566 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1567 details. Most functions analyzing DNA functions have been
1568 modified accordingly and are now much faster (dist.dna is now
1569 ca. 60 times faster).
1573 CHANGES IN APE VERSION 1.9-4
1578 o A bug was fixed in edgelabels().
1580 o as.phylo.hclust() did not work correctly when the object of
1581 class "hclust" has its labels set to NULL: the returned tree has
1582 now its tip labels set to "1", "2", ...
1584 o consensus could fail if some tip labels are a subset of others
1585 (e.g., "a" and "a_1"): this is now fixed.
1587 o mlphylo() failed in most cases if some branch lengths of the
1588 initial tree were greater than one: an error message is now
1591 o mlphylo() failed in most cases when estimating the proportion of
1592 invariants: this is fixed.
1596 CHANGES IN APE VERSION 1.9-3
1601 o The new function edgelabels adds labels on the edge of the tree
1602 in the same way than nodelabels or tiplabels.
1607 o multi2di() did not handle correctly branch lengths with the
1608 default option `random = TRUE': this is now fixed.
1610 o A bug was fixed in nuc.div() when using pairwise deletions.
1612 o A bug occurred in the analysis of bipartitions with large
1613 numbers of large trees, with consequences on prop.part,
1614 prop.clades, and boot.phylo.
1616 o The calculation of the Billera-Holmes-Vogtmann distance in
1617 dist.topo was wrong: this has been fixed.
1621 CHANGES IN APE VERSION 1.9-2
1626 o The new function ladderize reorganizes the internal structure of
1627 a tree to plot them left- or right-ladderized.
1629 o The new function dist.nodes computes the patristic distances
1630 between all nodes, internal and terminal, of a tree. It replaces
1631 the option `full = TRUE' of cophenetic.phylo (see below).
1636 o A bug was fixed in old2new.phylo().
1638 o Some bugs were fixed in chronopl().
1640 o The edge colours were not correctly displayed by plot.phylo
1641 (thank you to Li-San Wang for the fix).
1643 o cophenetic.phylo() failed with multichotomous trees: this is
1649 o read.dna() now returns the sequences in a matrix if they are
1650 aligned (interleaved or sequential format). Sequences in FASTA
1651 format are still returned in a list.
1653 o The option `full' of cophenetic.phylo() has been removed because
1654 it could not be used from the generic.
1657 DEPRECATED & DEFUNCT
1659 o rotate() has been removed; this function did not work correctly
1664 CHANGES IN APE VERSION 1.9-1
1669 o Trees with a single tip were not read correctly in R as the
1670 element `Nnode' was not set: this is fixed.
1672 o unroot() did not set correctly the number of nodes of the
1673 unrooted tree in most cases.
1675 o read.GenBank() failed when fetching very long sequences,
1676 particularly of the BX-series.
1678 o A bug was introduced in read.tree() with ape 1.9: it has been
1683 CHANGES IN APE VERSION 1.9
1688 o There are two new print `methods' for trees of class "phylo" and
1689 lists of trees of class "multi.tree", so that they are now
1690 displayed in a compact and informative way.
1692 o There are two new functions, old2new.phylo and new2old.phylo,
1693 for converting between the old and new coding of the class
1696 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1697 LogDet ("logdet"), and paralinear ("paralin").

1713 o ace() did not return the correct index matrix with custom
1714 models: this is fixed.
1716 o multi2di() did not work correctly when resolving multichotomies
1717 randomly: the topology was always the same, only the arrangement
1718 of clades was randomized: this is fixed. This function now
1719 accepts trees with no branch lengths.
1721 o The output of diversi.gof() was blurred by useless prints when a
1722 user distribution was specified. This has been corrected, and
1723 the help page of this function has been expanded.
1728 o The internal structure of the class "phylo" has been changed:
1729 see the document "Definition of Formats for Coding Phylogenetic
1730 Trees in R" for the details. In addition, the code of most
1731 functions has been improved.
1733 o Several functions have been improved by replacing some R codes
1734 by C codes: pic, plot.phylo, and reorder.phylo.
1736 o There is now a citation information: see citation("ape") in R.
1738 o write.tree() now does not add extra 0's to branch lengths so
1739 that 1.23 is printed "1.23" by default, not "1.2300000000".
1741 o The syntax of bind.tree() has been simplified. This function now
1742 accepts trees with no branch lengths, and handles correctly node
1745 o The option `as.numeric' of mrca() has been removed.
1747 o The unused options `format' and `rooted' of read.tree() have
1750 o The unused option `format' of write.tree() has been removed.
1752 o The use of node.depth() has been simplified.
1756 CHANGES IN APE VERSION 1.8-5
1761 o Two new functions read.nexus.data() and write.nexus.data(),

1763 sequences in NEXUS files.
1765 o The new function reorder.phylo() reorders the internal structure
1766 of a tree of class "phylo". It is used as the generic, e.g.,
1769 o read.tree() and read.nexus() can now read trees with a single
1772 o The new data set `cynipids' supplies a set of protein sequences
1778 o The code of all.equal.phylo() has been completely rewritten
1779 (thanks to Benoît Durand) which fixes several bugs.
1781 o read.tree() and read.nexus() now checks the labels of the tree
1782 to remove or substitute any characters that are illegal in the
1783 Newick format (parentheses, etc.)
1785 o A negative P-value could be returned by mantel.test(): this is
1790 CHANGES IN APE VERSION 1.8-4
1795 o The new function sh.test() computes the Shimodaira-
1798 o The new function collapse.singles() removes the nodes with a
1799 single descendant from a tree.
1801 o plot.phylo() has a new argument `tip.color' to specify the
1802 colours of the tips.
1804 o mlphylo() has now an option `quiet' to control the display of
1805 the progress of the analysis (the default is FALSE).
1810 o read.dna() did not read correctly sequences in sequential format
1811 with leading alignment gaps "-": this is fixed.
1813 o ace() returned a list with no class so that the generic
1814 functions (anova, logLik, ...) could not be used directly. This
1815 is fixed as ace() now returns an object of class "ace".
1817 o anova.ace() had a small bug when computing the number of degrees
1818 of freedom: this is fixed.
1820 o mlphylo() did not work when the sequences were in a matrix or
1821 a data frame: this is fixed.
1823 o rtree() did not work correctly when trying to simulate an
1824 unrooted tree with two tips: an error message is now issued.
1829 o The algorithm of rtree() has been changed: it is now about 40,
1830 100, and 130 times faster for 10, 100, and 1000 tips,
1835 CHANGES IN APE VERSION 1.8-3
1840 o There are four new `method' functions to be used with the
1841 results of ace(): logLik(), deviance(), AIC(), and anova().
1843 o The plot method of phymltest has two new arguments: `main' to
1844 change the title, and `col' to control the colour of the
1845 segments showing the AIC values.
1847 o ace() has a new argument `ip' that gives the initial values used
1848 in the ML estimation with discrete characters (see the examples
1849 in ?ace). This function now returns a matrix giving the indices
1850 of the estimated rates when analysing discrete characters.
1852 o nodelabels() and tiplabels() have a new argument `pie' to
1853 represent proportions, with any number of categories, as
1854 piecharts. The use of the option `thermo' has been improved:
1855 there is now no limitation on the number of categories.
1860 o mlphylo() did not work with more than two partitions: this is
1863 o root() failed if the proposed outgroup was already an outgroup
1864 in the tree: this is fixed.
1866 o The `col' argument in nodelabels() and tiplabels() was not
1867 correctly passed when `text' was used: this is fixed.
1869 o Two bugs were fixed in mlphylo(): parameters were not always
1870 correctly output, and the estimation failed in some cases.
1872 o plot.phylo() was stuck when given a tree with a single tip: this
1873 is fixed and a message error is now returned.
1875 o An error was corrected in the help page of gammaStat regarding
1876 the calculation of P-values.
1878 o Using gls() could crash R when the number of species in the tree
1879 and in the variables were different: this is fixed.
1883 CHANGES IN APE VERSION 1.8-2
1888 o The new function mlphylo() fits a phylogenetic tree by maximum
1889 likelihood from DNA sequences. Its companion function DNAmodel()
1890 is used to define the substitution model which may include
1891 partitioning. There are methods for logLik(), deviance(), and
1892 AIC(), and the summary() method has been extended to display in
1893 a friendly way the results of this model fitting. Currently, the
1894 functionality is limited to estimating the substitution and
1895 associated parameters and computing the likelihood.
1897 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1898 tests for single effects in GEE-based comparative method. A
1899 warning message is printed if there is not enough degrees of
1905 o An error message was sometimes issued by plot.multi.tree(),
1906 though with no consequence.
1910 CHANGES IN APE VERSION 1.8-1
1915 o There is a new plot method for lists of trees (objects of class
1916 "multi.tree"): it calls plot.phylo() internally and is
1917 documented on the same help page.
1922 o A bug was fixed in the C code that analyzes bipartitions: this
1923 has impact on several functions like prop.part, prop.clades,
1924 boot.phylo, or consensus.
1926 o root() did not work correctly when the specified outgroup had
1927 more than one element: this is fixed.
1929 o dist.dna() sometimes returned a warning inappropriately: this
1932 o If the distance object given to nj() had no rownames, nj()
1933 returned a tree with no tip labels: it now returns tips labelled
1934 "1", "2", ..., corresponding to the row numbers.
1939 o nj() has been slightly changed so that tips with a zero distance
1940 are first aggregated with zero-lengthed branches; the usual NJ
1941 procedure is then performed on a distance matrix without 0's.
1945 CHANGES IN APE VERSION 1.8
1950 o The new function chronopl() estimates dates using the penalized
1951 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1953 o The new function consensus() calculates the consensus tree of a
1956 o The new function evolve.phylo() simulates the evolution of
1957 continuous characters along a phylogeny under a Brownian model.
1959 o The new plot method for objects of class "ancestral" displays a
1960 tree together with ancestral values, as returned by the above
1963 o The new function as.phylo.formula() returns a phylogeny from a
1964 set of nested taxonomic variables given as a formula.
1966 o The new function read.caic() reads trees in CAIC format.
1968 o The new function tiplabels() allows to add labels to the tips
1969 of a tree using text or plotting symbols in a flexible way.
1971 o The new function unroot() unroots a phylogeny.
1973 o multi2di() has a new option, `random', which specifies whether
1974 to resolve the multichotomies randomly (the default) or not.
1976 o prop.part() now returns an object of class "prop.part" for which
1977 there are print (to display a partition in a more friendly way)
1978 and summary (to extract the numbers) methods.
1980 o plot.phylo() has a new option, `show.tip.label', specifying
1981 whether to print the labels of the tips. The default is TRUE.
1983 o The code of nj() has been replaced by a faster C code: it is now
1984 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1987 o write.nexus() now writes whether a tree is rooted or not.
1992 o Two bugs have been fixed in root(): unrooted trees are now
1993 handled corretly, and node labels are now output normally.
1995 o A bug was fixed in phymltest(): the executable couldn't be found
1998 o Three bugs have been fixed in ace(): computing the likelihood of
1999 ancestral states of discrete characters failed, custom models
2000 did not work, and the function failed with a null gradient (a
2001 warning message is now returned; this latter bug was also
2002 present in yule.cov() as well and is now fixed).
2004 o pic() hanged out when missing data were present: an error is now
2007 o A small bug was fixed in dist.dna() where the gamma correction
2008 was not always correctly dispatched.
2010 o plot.phylo() plotted correctly the root edge only when the tree
2011 was plotted rightwards: this works now for all directions.
2016 o dist.taxo() has been renamed as weight.taxo().
2018 o dist.phylo() has been replaced by the method cophenetic.phylo().
2020 o Various error and warning messages have been improved.
2024 CHANGES IN APE VERSION 1.7
2027 o The new function ace() estimates ancestral character states for
2028 continuous characters (with ML, GLS, and contrasts methods), and
2029 discrete characters (with ML only) for any number of states.
2031 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
2032 of directional evolution for continuous characters. The user
2033 specifies the node(s) of the tree where the character optimum
2036 o The new function is.rooted() tests whether a tree (of class
2039 o The new function rcoal() generates random ultrametric trees with
2040 the possibility to specify the function that generates the
2041 inter-nodes distances.
2043 o The new function mrca() gives for all pairs of tips in a tree
2044 (and optionally nodes too) the most recent common ancestor.
2046 o nodelabels() has a new option `thermo' to plot proportions (up
2047 to three classes) on the nodes of a tree.
2049 o rtree() has been improved: it can now generate rooted or
2050 unrooted trees, and the mathematical function that generates the
2051 branch lengths may be specified by the user. The tip labels may
2052 be given directly in the call to rtree. The limit cases (n = 2,
2053 3) are now handled correctly.
2055 o dist.topo() has a new argument `method' with two choices: "PH85"
2056 for Penny and Henny's method (already available before and now
2057 the default), and "BHV01" for the geometric distance by Billera
2058 et al. (2001, Adv. Appl. Math. 27:733).
2060 o write.tree() has a new option, `digits', which specifies the
2061 number of digits to be printed in the Newick tree. By default
2062 digits = 10. The numbers are now always printed in decimal form
2063 (i.e., 1.0e-1 is now avoided).
2065 o dist.dna() can now compute the raw distances between pairs of
2066 DNA sequences by specifying model = "raw".
2068 o dist.phylo() has a new option `full' to possibly compute the
2069 distances among all tips and nodes of the tree. The default is
2075 o Several bugs were fixed in all.equal.phylo().
2077 o dist.dna() did not handle correctly gaps ("-") in alignments:
2078 they are now considered as missing data.
2080 o rotate() did not work if the tips were not ordered: this is
2083 o mantel.test() returned NA in some special cases: this is fixed
2084 and the function has been improved and is now faster.
2086 o A bug was fixed in diversi.gof() where the calculation of A² was
2089 o cherry() did not work correctly under some OSs (mainly Linux):
2092 o is.binary.tree() has been modified so that it works with both
2093 rooted and unrooted trees.
2095 o The documentation of theta.s() was not correct: this has been
2098 o plot.mst() did not work correctly: this is fixed.
2102 CHANGES IN APE VERSION 1.6
2107 o The new function dist.topo() computes the topological distances
2110 o The new function boot.phylo() performs a bootstrap analysis on
2111 phylogeny estimation.
2113 o The new functions prop.part() and prop.clades() analyse
2114 bipartitions from a series of trees.
2119 o read.GenBank() now uses the EFetch utility of NCBI instead of
2120 the usual Web interface: it is now much faster (e.g., 12 times
2121 faster to retrieve 8 sequences, 37 times for 60 sequences).
2126 o Several bugs were fixed in read.dna().
2128 o Several bugs were fixed in diversi.time().
2130 o is.binary.tree() did not work correctly if the tree has no edge
2131 lengths: this is fixed.
2133 o drop.tip() did not correctly propagated the `node.label' of a
2134 tree: this is fixed.
2138 CHANGES IN APE VERSION 1.5
2143 o Two new functions, as.matching.phylo() and as.phylo.matching(),
2144 convert objects between the classes "phylo" and "matching". The
2145 latter implements the representation of binary trees introduced by
2146 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
2147 as.matching() has been introduced as well.
2149 o Two new functions, multi2di() and di2multi(), allow to resolve
2150 and collapse multichotomies with branches of length zero.
2152 o The new function nuc.div() computes the nucleotide diversity
2153 from a sample a DNA sequences.
2155 o dist.dna() has been completely rewritten with a much faster
2156 (particularly for large data sets) C code. Eight models are
2157 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
2158 option `method' has been renamed `model'). Computation of variance
2159 is available for all models. A gamma-correction is possible for
2160 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
2161 to remove sites with missing data on a pairwise basis. The option
2162 `GCcontent' has been removed.
2164 o read.GenBank() has a new option (species.names) which specifies
2165 whether to return the species names of the organisms in addition
2166 to the accession numbers of the sequences (this is the default
2169 o write.nexus() can now write several trees in the same NEXUS file.
2171 o drop.tip() has a new option `root.edge' that allows to specify the
2172 new root edge if internal branches are trimmed.
2177 o as.phylo.hclust() failed if some labels had parentheses: this
2180 o Several bugs were fixed in all.equal.phylo(). This function now
2181 returns the logical TRUE if the trees are identical but with
2182 different representations (a report was printed previously).
2184 o read.GenBank() did not correctly handle ambiguous base codes:
2190 o birthdeath() now returns an object of class "birthdeath" for
2191 which there is a print method.
2195 CHANGES IN APE VERSION 1.4
2200 o The new function nj() performs phylogeny estimation with the
2201 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
2204 o The new function which.edge() identifies the edges of a tree
2205 that belong to a group specified as a set of tips.
2207 o The new function as.phylo.phylog() converts an object of class
2208 "phylog" (from the package ade4) into an object of class
2211 o The new function axisPhylo() draws axes on the side of a
2214 o The new function howmanytrees() calculates the number of trees
2215 in different cases and giving a number of tips.
2217 o write.tree() has a new option `multi.line' (TRUE by default) to
2218 write a Newick tree on several lines rather than on a single
2221 o The functionalities of zoom() have been extended. Several
2222 subtrees can be visualized at the same time, and they are marked
2223 on the main tree with colors. The context of the subtrees can be
2224 marked with the option `subtree' (see below).
2226 o drop.tip() has a new option `subtree' (FALSE by default) which
2227 specifies whether to output in the tree how many tips have been
2230 o The arguments of add.scale.bar() have been redefined and have
2231 now default values (see ?add.scale.bar for details). This
2232 function now works even if the plotted tree has no edge length.
2234 o plot.phylo() can now plot radial trees, but this does not take
2235 edge lengths into account.
2237 o In plot.phylo() with `type = "phylogram"', if the values of
2238 `edge.color' and `edge.width' are identical for sister-branches,
2239 they are propagated to the vertical line that link them.
2244 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
2245 crashing. This is fixed.
2247 o In plot.phylo(), the options `edge.color' and `edge.width' are
2248 now properly recycled; their default values are now "black" and
2251 o A bug has been fixed in write.nexus().
2256 o The function node.depth.edgelength() has been removed and
2257 replaced by a C code.
2261 CHANGES IN APE VERSION 1.3-1
2266 o The new function nodelabels() allows to add labels to the nodes
2267 of a tree using text or plotting symbols in a flexible way.
2269 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
2270 numeric values specifying the lower and upper limits on the x-
2271 and y-axes. This allows to leave some space on any side of the
2272 tree. If a single value is given, this is taken as the upper
2277 CHANGES IN APE VERSION 1.3
2282 o The new function phymltest() calls the software PHYML and fits
2283 28 models of DNA sequence evolution. There are a print method to
2284 display likelihood and AIC values, a summary method to compute
2285 the hierarchical likelihood ratio tests, and a plot method to
2286 display graphically the AIC values of each model.
2288 o The new function yule.cov() fits the Yule model with covariates,
2289 a model where the speciation rate is affected by several species
2290 traits through a generalized linear model. The parameters are
2291 estimated by maximum likelihood.
2293 o Three new functions, corBrownian(), corGrafen(), and
2294 corMartins(), compute the expected correlation structures among
2295 species given a phylogeny under different models of evolution.
2296 These can be used for GLS comparative phylogenetic methods (see
2297 the examples). There are coef() and corMatrix() methods and an
2298 Initialize.corPhyl() function associated.
2300 o The new function compar.cheverud() implements Cheverud et al.'s
2301 (1985; Evolution 39:1335) phylogenetic comparative method.
2303 o The new function varcomp() estimates variance components; it has
2306 o Two new functions, panel.superpose.correlogram() and
2307 plot.correlogramList(), allow to plot several phylogenetic
2310 o The new function node.leafnumber() computes the number of leaves
2311 of a subtree defined by a particular node.
2313 o The new function node.sons() gets all tags of son nodes from a
2316 o The new function compute.brlen() computes the branch lengths of
2317 a tree according to a specified method.
2319 o plot.phylo() has three new options: "cex" controls the size of
2320 the (tip and node) labels (thus it is no more needed to change
2321 the global graphical parameter), "direction" which allows to
2322 plot the tree rightwards, leftwards, upwards, or downwards, and
2323 "y.lim" which sets the upper limit on the y-axis.
2328 o Some functions which try to match tip labels and names of
2329 additional data (e.g. vector) are likely to fail if there are
2330 typing or syntax errors. If both series of names do not perfectly
2331 match, they are ignored and a warning message is now issued.
2332 These functions are bd.ext, compar.gee, pic. Their help pages
2333 have been clarified on this point.
2337 CHANGES IN APE VERSION 1.2-7
2342 o The new function root() reroots a phylogenetic tree with respect
2343 to a specified outgroup.
2345 o The new function rotate() rotates an internal branch of a tree.
2347 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
2348 trees) controls the display of the tip labels in unrooted trees.
2349 This display has been greatly improved: the tip labels are now not
2350 expected to overlap with the tree (particularly if lab4ut =
2351 "axial"). In all cases, combining appropriate values of "lab4ut"
2352 and the font size (via "par(cex = )") should result in readable
2353 unrooted trees. See ?plot.phylo for some examples.
2355 o In drop.tip(), the argument `tip' can now be numeric or character.
2360 o drop.tip() did not work correctly with trees with no branch
2361 lengths: this is fixed.
2363 o A bug in plot.phylo(..., type = "unrooted") made some trees being
2364 plotted with some line crossings: this is now fixed.
2368 CHANGES IN APE VERSION 1.2-6
2373 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
2374 correlogram.phylo, dist.taxo, plot.correlogram) have been added
2375 to implement comparative methods with an autocorrelation approach.
2377 o A new data set describing some life history traits of Carnivores
2383 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
2388 o When plotting a tree with plot.phylo(), the new default of the
2389 option `label.offset' is now 0, so the labels are always visible.
2393 CHANGES IN APE VERSION 1.2-5
2398 o The new function bd.ext() fits a birth-death model with combined
2399 phylogenetic and taxonomic data, and estimates the corresponding
2400 speciation and extinction rates.
2405 o The package gee is no more required by ape but only suggested
2406 since only the function compar.gee() calls gee.
2410 CHANGES IN APE VERSION 1.2-4
2415 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
2416 and lines.popsize) implementing a new approach for inferring the
2417 demographic history from genealogies using a reversible jump
2418 MCMC have been introduced.
2420 o The unit of time in the skyline plot and in the new plots can
2421 now be chosen to be actual years, rather than substitutions.
2425 CHANGES IN APE VERSION 1.2-3
2430 o The new function rtree() generates a random binary tree with or
2431 without branch lengths.
2433 o Two new functions for drawing lineages-through-time (LTT) plots
2434 are provided: ltt.lines() adds a LTT curve to an existing plot,
2435 and mltt.plot() does a multiple LTT plot giving several trees as
2436 arguments (see `?ltt.plot' for details).
2441 o Some taxon names made R crashing when calling as.phylo.hclust():
2444 o dist.dna() returned an error with two identical DNA sequences
2445 (only using the Jukes-Cantor method returned 0): this is fixed.
2450 o The function dist.phylo() has been re-written using a different
2451 algorithm: it is now about four times faster.
2453 o The code of branching.times() has been improved: it is now about
2458 CHANGES IN APE VERSION 1.2-2
2463 o The new function seg.sites() finds the segregating sites in a
2464 sample of DNA sequences.
2469 o A bug introduced in read.tree() and in read.nexus() with version
2472 o A few errors were corrected and a few examples were added in the
2477 CHANGES IN APE VERSION 1.2-1
2482 o plot.phylo() can now draw the edge of the root of a tree if it
2483 has one (see the new option `root.edge', its default is FALSE).
2488 o A bug was fixed in read.nexus(): files with semicolons inside
2489 comment blocks were not read correctly.
2491 o The behaviour of read.tree() and read.nexus() was corrected so
2492 that tree files with badly represented root edges (e.g., with
2493 an extra pair of parentheses, see the help pages for details)
2494 are now correctly represented in the object of class "phylo";
2495 a warning message is now issued.
2499 CHANGES IN APE VERSION 1.2
2504 o plot.phylo() has been completely re-written and offers several
2505 new functionalities. Three types of trees can now be drawn:
2506 phylogram (as previously), cladogram, and unrooted tree; in
2507 all three types the branch lengths can be drawn using the edge
2508 lengths of the phylogeny or not (e.g., if the latter is absent).
2509 The vertical position of the nodes can be adjusted with two
2510 choices (see option `node.pos'). The code has been re-structured,
2511 and two new functions (potentially useful for developpers) are
2512 documented separately: node.depth.edgelength() and node.depth();
2513 see the respective help pages for details.
2515 o The new function zoom() allows to explore very large trees by
2516 focusing on a small portion of it.
2518 o The new function yule() fits by maximum likelihood the Yule model
2519 (birth-only process) to a phylogenetic tree.
2521 o Support for writing DNA sequences in FASTA format has been
2522 introduced in write.dna() (support for reading sequences in
2523 this format was introduced in read.dna() in version 1.1-2).
2524 The function has been completely re-written, fixing some bugs
2525 (see below); the default behaviour is no more to display the
2526 sequences on the standard output. Several options have been
2527 introduced to control the sequence printing in a flexible
2528 way. The help page has been extended.
2530 o A new data set is included: a supertree of bats in NEXUS format.
2535 o In theta.s(), the default of the option `variance' has
2536 been changed to `FALSE' (as was indicated in the help page).
2538 o Several bugs were fixed in the code of all.equal.phylo().
2540 o Several bugs were fixed in write.dna(), particularly this
2541 function did not work with `format = "interleaved"'.
2543 o Various errors were corrected in the help pages.
2548 o The argument names of as.hclust.phylo() have been changed
2549 from "(phy)" to "(x, ...)" to conform to the definition of
2550 the corresponding generic function.
2552 o gamma.stat() has been renamed gammaStat() to avoid confusion
2553 since gamma() is a generic function.
2557 CHANGES IN APE VERSION 1.1-3
2562 o base.freq() previously did not return a value of 0 for
2563 bases absent in the data (e.g., a vector of length 3 was
2564 returned if one base was absent). This is now fixed (a
2565 vector of length 4 is always returned).
2567 o Several bugs were fixed in read.nexus(), including that this
2568 function did not work in this absence of a "TRANSLATE"
2569 command in the NEXUS file, and that the commands were
2574 CHANGES IN APE VERSION 1.1-2
2579 o The Tamura and Nei (1993) model of DNA distance is now implemented
2580 in dist.dna(): five models are now available in this function.
2582 o A new data set is included: a set of 15 sequences of the
2583 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2589 o A bug in read.nexus() was fixed.
2591 o read.dna() previously did not work correctly in most cases.
2592 The function has been completely re-written and its help page
2593 has been considerably extended (see ?read.dna for details).
2594 Underscores (_) in taxon names are no more replaced with
2595 spaces (this behaviour was undocumented).
2597 o A bug was fixed in write.dna().
2601 CHANGES IN APE VERSION 1.1-1
2606 o A bug in read.tree() introduced in APE 1.1 was fixed.
2608 o A bug in compar.gee() resulted in an error when trying to fit
2609 a model with `family = "binomial"'. This is now fixed.
2613 CHANGES IN APE VERSION 1.1
2618 o The Klastorin (1982) method as suggested by Misawa and Tajima
2619 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2620 on the basis of phylogenetic trees has been implemented (see
2621 the function klastorin()).
2623 o Functions have been added to convert APE's "phylo" objects in
2624 "hclust" cluster objects and vice versa (see the help page of
2625 as.phylo for details).
2627 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2628 are introduced for the estimation of absolute evolutionary rates
2629 (ratogram) and dated clock-like trees (chronogram) from
2630 phylogenetic trees using the non-parametric rate smoothing approach
2631 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2633 o A summary method is now provided printing a summary information on a
2634 phylogenetic tree with, for instance, `summary(tree)'.
2636 o The behaviour of read.tree() was changed so that all spaces and
2637 tabulations in tree files are now ignored. Consequently, spaces in tip
2638 labels are no more allowed. Another side effect is that read.nexus()
2639 now does not replace the underscores (_) in tip labels with spaces
2640 (this behaviour was undocumented).
2642 o The function plot.phylo() has a new option (`underscore') which
2643 specifies whether the underscores in tip labels should be written on
2644 the plot as such or replaced with spaces (the default).
2646 o The function birthdeath() now computes 95% confidence intervals of
2647 the estimated parameters using profile likelihood.
2649 o Three new data sets are included: a gene tree estimated from 36
2650 landplant rbcL sequences, a gene tree estimated from 32 opsin
2651 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2656 o A bug was fixed in dist.gene() where nothing was returned.
2658 o A bug in plot.mst() was fixed.
2660 o A bug in vcv.phylo() resulted in false correlations when the
2661 option `cor = TRUE' was used (now fixed).
2665 CHANGES IN APE VERSION 1.0
2670 o Two new functions, read.dna() and write.dna(), read/write in a file
2671 DNA sequences in interleaved or in sequential format.
2673 o Two new functions, read.nexus() and write.nexus(), read/write trees
2676 o The new function bind.tree() allows to bind two trees together,
2677 possibly handling root edges to give internal branches.
2679 o The new function drop.tip() removes the tips in a phylogenetic tree,
2680 and trims (or not) the corresponding internal branches.
2682 o The new function is.ultrametric() tests if a tree is ultrametric.
2684 o The function plot.phylo() has more functionalities such as drawing the
2685 branches with different colours and/or different widths, showing the
2686 node labels, controling the position and font of the labels, rotating
2687 the labels, and controling the space around the plot.
2689 o The function read.tree() can now read trees with no branch length,
2690 such as "(a,b),c);". Consequently, the element `edge.length' in
2691 objects of class "phylo" is now optional.
2693 o The function write.tree() has a new default behaviour: if the default
2694 for the option `file' is used (i.e. file = ""), then a variable of
2695 mode character containing the tree in Newick format is returned which
2696 can thus be assigned (e.g., tree <- write.tree(phy)).
2698 o The function read.tree() has a new argument `text' which allows
2699 to read the tree in a variable of mode character.
2701 o A new data set is included: the phylogenetic relationships among
2702 the orders of birds from Sibley and Ahlquist (1990).
2706 CHANGES IN APE VERSION 0.2-1
2711 o Several bugs were fixed in the help pages.
2715 CHANGES IN APE VERSION 0.2
2720 o The function write.tree() writes phylogenetic trees (objects of class
2721 "phylo") in an ASCII file using the Newick parenthetic format.
2723 o The function birthdeath() fits a birth-death model to branching times
2724 by maximum likelihood, and estimates the corresponding speciation and
2727 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2730 o The function is.binary.tree() tests whether a phylogeny is binary.
2732 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2733 as well as some methods are introduced.
2735 o Several functions, including some generics and methods, for computing
2736 skyline plot estimates (classic and generalized) of effective
2737 population size through time are introduced and replace the function
2738 skyline.plot() in version 0.1.
2740 o Two data sets are now included: the phylogenetic relationships among
2741 the families of birds from Sibley and Ahlquist (1990), and an
2742 estimated clock-like phylogeny of HIV sequences sampled in the
2743 Democratic Republic of Congo.
2746 DEPRECATED & DEFUNCT
2748 o The function skyline.plot() in ape 0.1 has been deprecated and
2749 replaced by more elaborate functions (see above).
2754 o Two important bugs were fixed in plot.phylo(): phylogenies with
2755 multichotomies not at the root or not with only terminal branches,
2756 and phylogenies with a single node (i.e. only terminal branches)
2757 did not plot. These trees should be plotted correctly now.
2759 o Several bugs were fixed in diversi.time() in the computation of
2762 o Various errors were corrected in the help pages.
