11 o write.dna(format = "fasta") now conforms more closely to the
12 FASTA standard thanks to François Michonneau.
14 o print.DNAbin() does not print base compositions if there are more
15 than one million nucleotides.
19 CHANGES IN APE VERSION 3.0-4
24 o read.dna() failed to read Phylip files if the first line used
25 tabulations instead of white spaces.
27 o read.dna() failed to read Phylip or Clustal files with less than
28 10 nucleotides. (See other changes in this function below.)
32 o read.dna() now requires at least one space (or tab) between the
33 taxa names and the sequences (whatever the length of taxa
34 names). write.dna() now follows the same rule.
36 o The option 'seq.names' of read.dna has been removed.
38 o The files ape-defunct.R and ape-defunct.Rd, which have not been
39 modified for almost two years, have been removed.
41 o The C code of bionj() has been reworked: it is more stable (by
42 avoiding passing character strings), slightly faster (by about
43 20%), and numerically more accurate.
45 o The C code of fastme.*() has been slightly modified and should
46 be more stable by avoiding passing character strings (the
47 results are identical to the previous versions).
49 o The file src/newick.c has been removed.
53 CHANGES IN APE VERSION 3.0-3
58 o birthdeath() now catches errors and warnings much better so that
59 a result is returned in most cases.
64 o Because of problems with character string manipulation in C, the
65 examples in ?bionj and in ?fastme have been disallowed. In the
66 meantime, these functions might be unstable. This will be solved
71 CHANGES IN APE VERSION 3.0-2
76 o The new function alex (alignment explorator) zooms in a DNA
77 alignment and opens the result in a new window.
82 o compute.brtime() did not completely randomized the order of the
85 o write.nexus() did not work correctly with rooted trees (thanks
86 to Matt Johnson for the fix).
88 o mltt.plot(, backward = FALSE) did not set the x-axis correctly.
90 o A bug was introduced in prop.clades() with ape 3.0. The help page
91 has been clarified relative to the use of the option 'rooted'.
93 o mantel.test() printed a useless warning message.
95 o plot.phylo(, direction = "downward") ignored 'y.lim'.
97 o is.monophyletic() did not work correctly if 'tips' was not stored
100 o prop.part() could make R crash if the first tree had many
103 o njs(), bionjs(), and mvrs() now return an error if 'fs < 1'.
105 o SDM() did not work correctly. The code has also been generally
111 o The DESCRIPTION file has been updated.
113 o The option 'original.data' of write.nexus() has been removed.
115 o The files bionjs.c, mvr.c, mvrs.c, njs.c, triangMtd.c, and
116 triangMtds.c have been improved which should fix some bugs in
117 the corresponding functions.
119 o dist.gene() now coerces input data frame as matrix resulting in
120 much faster calculations (thanks to a suggestion by Markus
125 CHANGES IN APE VERSION 3.0-1
130 o dist.dna() has two new models: "indel" and "indelblock".
132 o bind.tree() now accepts 'position' > 0 when the trees have no
133 banch length permitting to create a node in 'x' when grafting
134 'y' (see ?bind.tree for details).
139 o cophyloplot( , rotate = TRUE) made R hanged after a few clicks.
140 Also the tree is no more plotted twice.
142 o read.GenBank() has been updated to work with EFetch 2.0.
144 o unroot() on trees in "pruningwise" order did not respect this
149 CHANGES IN APE VERSION 3.0
154 o The three functions dyule, dbd, and dbdTime calculate the
155 density probability (i.e., the distribution of the number of
156 species) for the Yule, the constant and the time-dependent
157 birth-beath models, respectively. These probabilities can be
158 conditional on no extinction and/or on a log-scale.
160 o plot.phylo() has a new option 'rotate.tree' to rotate unrooted,
161 fan, or radial trees around the center of the plot.
163 o boot.phylo() and prop.clades() have a new option rooted =
164 FALSE. Note that the behaviour of prop.part() is unchanged.
166 o edgelabels() has a new option 'date' to place labels on edges of
167 chronograms using the time scale (suggestion by Rob Lanfear).
172 o In chronopl(), the code setting the initial dates failed in
173 complicated settings (several dates known within intervals).
174 This has been generally improved and should result in faster
175 and more efficient convergence even in simple settings.
177 o mantel.test() sometimes returned P-values > 1 with the default
180 o extract.clade() sometimes shuffled some tip labels (thanks to
181 Ludovic Mallet and Mahendra Mariadassou for the fix).
183 o clustal() should now find by default the executable under Windows.
188 o The code of yule() has been simplified and is now much faster for
191 o The code of mantel.test() has been adjusted to be consistent
192 with common permutation tests.
194 o The C code of base.freq() has been improved and is now nearly 8
197 o The option 'original.data' of write.nexus() is now deprecated and
198 will be removed in a future release.
200 o The code of is.ultrametric() has been improved and is now 3 times
203 o The code of vcv.phylo() has been improved and is now 10 or 30
204 times faster for 100 or 1000 tips, respectively. Consequently,
205 fitting models with PGLS will be faster overall.
209 CHANGES IN APE VERSION 2.8
214 o Twelve new functions have been written by Andrei-Alin Popescu:
215 additive, ultrametric, is.compatible, arecompatible, mvr, mvrs,
216 njs, bionjs, SDM, treePop, triangMtd, triangMtd*.
218 o A new class "bitsplits" has been created by Andrei-Alin Popescu
219 to code splits (aka, bipartition).
221 o There is a new generic function as.bitsplits with a method to
222 convert from the class "prop.part" to the class "bitsplits".
224 o The new function ltt.coplot plots on the same scales a tree and
225 the derived LTT plot.
227 o ltt.plot() has two new options: backward and tol. It can now
228 handle non-ultrametic trees and its internal coding has been
229 improved. The coordinates of the plot can now be computed with
230 the new function ltt.plot.coords.
235 o prop.part() crashed if some trees had some multichotomies.
239 CHANGES IN APE VERSION 2.7-3
244 o The new function compute.brtime computes and sets branching times.
246 o mantel.test() has a new argument 'alternative' which is
247 "two-sided" by default. Previously, this test was one-tailed
248 with no possibility to change.
250 o ace() can now do REML estimation with continuous characters,
251 giving better estimates of the variance of the Brownian motion
257 o Branch lengths were wrongly updated with bind.tree(, where = <tip>,
258 position = 0). (Thanks to Liam Revell for digging this bug out.)
260 o Simulation of OU process with rTraitCont() did not work correctly.
261 This now uses formula from Gillespie (1996) reduced to a BM
262 process when alpha = 0 to avoid division by zero. The option
263 'linear' has been removed.
265 o Cross-validation in chronopl() did not work when 'age.max' was
268 o consensus(, p = 0.5) could return an incorrect tree if some
269 incompatible splits occur in 50% of the trees (especially with
270 small number of trees).
272 o c() with "multiPhylo" did not work correctly (thanks to Klaus
273 Schliep for the fix).
275 o root() failed in some cases with an outgroup made of several tips.
276 The help page has been clarified a bit.
280 CHANGES IN APE VERSION 2.7-2

286 a constructor function evonet(), a print() and a plot() methods,
287 and four conversion methods to the classes "phylo", "networx",
288 "network", and "igraph".
290 o The new function rTraitMult does multivariate traits simulation
291 with user-defined models.
293 o plot.phylo() has a new option 'plot = TRUE'. If FALSE, the tree
294 is not plotted but the graphical device is set and the
295 coordinates are saved as usual.
297 o diversity.contrast.test() gains a fourth version of the test with
298 method = "logratio"; the literature citations have been clarified.
300 o add.scale.bar() has two new options, 'lwd' and 'lcol', to modify
301 the aspect of the bar.
303 o boot.phylo() now displays a progress bar by default (can be off
306 o There is a new predict() method for compar.gee().
311 o bionj() made R crash if distances were too large. It now returns
312 an error if at least one distance is greater than 100.
314 o drop.tip() returned a wrong tree if 'tip' was of zero length.
316 o read.nexus.data() failed with URLs.
318 o boot.phylo() returned overestimated support values in the
319 presence of identical or nearly identical sequences.

361 left-) clicks (an error was returned previously).
363 o read.nexus() should be robust to commands inserted in the TREES
368 CHANGES IN APE VERSION 2.7
373 o There is a new image() method for "DNAbin" objects: it plots DNA
374 alignments in a flexible and efficient way.
376 o Two new functions as.network.phylo and as.igraph.phylo convert
377 trees of class "phylo" into these respective network classes
378 defined in the packages of the same names.
380 o The three new functions clustal, muscle, and tcoffee perform
381 nucleotide sequence alignment by calling the external programs

415 column was redundant.
419 CHANGES IN APE VERSION 2.6-3
424 o rTraitCont() and rTraitDisc() gains a '...' argument used with
425 user-defined models (suggestion by Gene Hunt).
430 o as.hclust.phylo() now returns an error with unrooted trees.

438 o plot.phylo() did not recycle values of 'font', 'cex' and
439 'tip.color' correctly when type = "fan" or "radial".
441 o plot.phylo() ignored 'label.offset' when type = "radial", "fan", or
442 "unrooted" with lab4ut = "axial" (the placement of tip labels still
443 needs to be improved with lab4ut = "horizontal").
448 o In drop.fossil() the default tol = 0 has been raised to 1e-8.
450 o The help command ?phylo now points to the man page of read.tree()
451 where this class is described. Similarly, ?matching points to the
452 man page of as.matching().
456 CHANGES IN APE VERSION 2.6-2
461 o Two new functions, pic.ortho and varCompPhylip, implements the
462 orthonormal contrasts of Felsenstein (2008, Am Nat, 171:713). The
463 second function requires Phylip to be installed on the computer.

466 conditioned on no extinction for the taxonomic data.
471 o write.tree() failed to output correctly tree names.

524 any user-defined time-dependent speciation-extinction model. They
525 use continuous time algorithms.
527 o The new function drop.fossil removes the extinct species from a
530 o The new function bd.time fits a user-defined time-dependent
531 birth-death model. It is a generalization of yule.time() taking

546 control the aspect of thermometers: horiz = TRUE, width = NULL,
549 o compar.gee() has been improved with the new option 'corStruct' as an
550 alternative to 'phy' to specify the correlation structure, and
551 calculation of the QIC (Pan 2001, Biometrics). The display of the
552 results has also been improved.
554 o read.GenBank() has a new option 'gene.names' to return the name of
555 the gene (FALSE by default).
560 o extract.clade() sometimes shuffled the tip labels.
562 o plot.phylo(type = "unrooted") did not force asp = 1 (thanks to Klaus
565 o dist.dna(model = "logdet") used to divide distances by 4. The
566 documentation has been clarified on the formulae used.

588 text to be plotted in different fonts.
590 o There are now replacement operators for [, [[, and $ for the class
591 "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They possibly
592 check that the tip labels are the same in all trees.
594 o Objects of class "multiPhylo" can be built with c(): there are
595 methods for the classes "phylo" and "multiPhylo".
597 o The internal functions .compressTipLabel and .uncompressTipLabel are
603 o bind.tree(x, y, where, position = 0) did not work correctly if 'y'

664 'interactive' option to make the operation on a plotted tree.
666 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
667 association links; they are recycled like 'col' (which wasn't before).
672 o rTraitDisc() did not use its 'freq' argument correctly (it was
673 multiplied with the rate matrix column-wise instead of row-wise).
675 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
676 with NA values. Nothing is drawn now like with 'text' or 'pch'.
677 The same bug occurred with the 'pie' option.

688 in the correct direction though the tip labels were displayed
694 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
695 the sequences are correctly stored (in a list for c, in a matrix
696 for the two other functions).
700 CHANGES IN APE VERSION 2.5
705 o The new function parafit by Pierre Legendre tests for the
706 coevolution between hosts and parasites. It has a companion
707 function, pcoa, that does principal coordinate decomposition.
708 The latter has a biplot method.
710 o The new function lmorigin by Pierre Legendre performs multiple
711 regression through the origin with testing by permutation.
713 o The new functions rTraitCont and rTraitDisc simulate continuous and
714 discrete traits under a wide range of evolutionary models.
716 o The new function delta.plot does a delta plot following Holland et
717 al. (2002, Mol. Biol. Evol. 12:2051).
719 o The new function edges draws additional branches between any nodes
720 and/or tips on a plotted tree.
722 o The new function fancyarrows enhances arrows from graphics with
723 triangle and harpoon heads; it can be called from edges().

727 o The branch length score replaces the geodesic distance in dist.topo.
729 o Three new data sets are included: the gopher-lice data (gopher.D),
730 SO2 air pollution in 41 US cities (lmorigin.ex1, from Sokal &
731 Rohlf 1995), and some host-parasite specificity data
732 (lmorigin.ex2, from Legendre & Desdevises 2009).
737 o add.scale.bar() drew the bar outside the plotting region with the
738 default options with unrooted or radial trees.
740 o dist.topo() made R stuck when the trees had different sizes (thanks
741 to Otto Cordero for the fix).

756 o rtree() and rcoal() now accept a numeric vector for the 'br'
759 o vcv() is a new generic function with methods for the classes "phylo"
760 and "corPhyl" so that it is possible to calculate the var-cov matrix
761 for "transformation models". vcv.phylo() can still be used for trees
762 of class "phylo"; its argument 'cor' has been renamed 'corr'.
767 o bind.tree() failed when 'y' had no root edge.
769 o read.nexus() shuffled tip labels when the trees have no branch
770 lengths and there is a TRANSLATE block.
772 o read.nexus() does not try to translate node labels if there is a
773 translation table in the NEXUS file. See ?read.nexus for a
774 clarification on this behaviour.
776 o plot.multiPhylo() crashed R when plotting a list of trees with
777 compressed tip labels.
779 o write.nexus() did not translate the taxa names when asked for.
781 o plot.phylo(type = "fan") did not rotate the tip labels correctly
782 when the tree has branch lengths.

787 o nj() crashed with NA/NaN in the distance matrix: an error in now
792 CHANGES IN APE VERSION 2.4
797 o base.freq() has a new option 'freq' to return the counts; the
798 default is still to return the proportions.
803 o seg.sites() did not handle ambiguous nucleotides correctly: they
806 o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
807 the tree: the argument is now ignored.
809 o add.scale.bar() failed when 'x' and 'y' were given (thanks to Janet
815 o Trying to plot a tree with a single tip now returns NULL with a
816 warning (it returned an error previously).
818 o The way lines representing nodes are coloured in phylograms has
819 been modified (as well as their widths and types) following some
820 users' request; this is only for dichotomous nodes.
822 o The argument 'adj' in [node][tip][edge]labels() now works when
823 using 'pie' or 'thermo'.
825 o A more informative message error is now returned by dist.dna() when

880 o extract.clade() sometimes included too many edges.
882 o vcv.phylo() did not work correctly when the tree is in
885 o nj() did not handle correctly distance matrices with many 0's.
886 The code has also been significantly improved: 7, 70, 160 times
887 faster with n = 100, 500, 1000, respectively.
891 CHANGES IN APE VERSION 2.3-1
896 o The new function is.monophyletic tests the monophyly of a group.
898 o There is now a c() method for lists of class "DNAbin".
900 o yule.cov() now fits the null model, and its help page has been

926 o drop.tip(, subtree = TRUE) sometimes shuffled tip labels.
931 o [.multiPhylo and [.DNAbin now respect the original class.
933 o Instances of the form class(phy) == "phylo" have been replaced

958 labels in a flexible way.
960 o read.tree() and write.tree() have been modified so that they can
961 handle individual tree names.
963 o plot.phylo() has a new argument 'edge.lty' that specifies the
964 types of lines used for the edges (plain, dotted, dashed, ...)
966 o phymltest() has been updated to work with PhyML 3.0.1.
971 o drop.tip() shuffled tip labels in some cases.
973 o drop.tip() did not handle node.label correctly.
975 o is.ultrametric() now checks the ordering of the edge matrix.
977 o ace() sometimes returned negative values of likelihoods of
978 ancestral states (thanks to Dan Rabosky for solving this long
984 o The data set xenarthra has been removed.
988 CHANGES IN APE VERSION 2.2-4
992 o The bug fix in read.nexus() in version 2.2-3 was wrong: this is
993 now fixed. (Thanks to Peter Wragg for the fix!)
995 o A warning message occurred for no reason with ace(method="GLS").
1000 o There is now a general help page displayed with '?ape'.
1004 CHANGES IN APE VERSION 2.2-3

1024 multiple lines with different numbers of lines and/or with
1025 comments inserted within the trees).
1027 o ltt.plot(), ltt.lines(), and mltt.plot() did not count correctly
1028 the number of lineages with non-binary trees.
1033 o ape has now a namespace.
1035 o drop.tip() has been improved: it should be much faster and work
1036 better in some cases (e.g., see the example in ?zoom).
1040 CHANGES IN APE VERSION 2.2-2
1045 o dist.gene() has been substantially improved and gains an option
1046 'pairwise.deletion'.
1048 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
1054 o prop.part() failed with a single tree with the default option
1055 'check.labels = TRUE'.
1057 o summary.DNAbin() failed to display correctly the summary of
1058 sequence lengths with lists of sequences of 10,000 bases or more
1059 (because summary.default uses 4 significant digits by default).
1061 o read.nexus() failed to read a file with a single tree with line
1062 breaks in the Newick string.
1064 o del.gaps() returned a list of empty sequences when there were no
1070 o phymltest() has been updated for PhyML 3.0 and gains an option
1071 'append', whereas the option 'path2exec' has been removed.
1073 o rbind.DNAbin() and cbind.DNAbin() now accept a single matrix
1074 which is returned unchanged (instead of an error).
1076 o The data sets bird.orders and bird.families are now stored as
1077 Newick strings; i.e., the command data(bird.orders) calls
1082 CHANGES IN APE VERSION 2.2-1
1087 o The new function makeLabel() helps to modify labels of trees,
1088 lists of trees, or DNA sequences, with several utilities to
1089 truncate and/or make them unique, substituting some
1090 characters, and so on.
1092 o The new function del.gaps() removes insertion gaps ("-") in a
1093 set of DNA sequences.
1095 o read.dna() can now read Clustal files (*.aln).
1100 o root() failed with 'resolve.root = TRUE' when the root was
1101 already the specified root.
1103 o Several bugs were fixed in mlphylo().
1105 o collapsed.singles() did not propagate the 'Nnode' and
1106 'node.labels' elements (thanks to Elizabeth Purdom for the fix).
1108 o read.nexus() failed to remove correctly the comments within
1111 o read.nexus() failed to read a file with a single tree and no

1125 o The option 'check.labels' of consensus() and prop.part() is now
1128 o write.dna() now does not truncate names to 10 characters with
1133 CHANGES IN APE VERSION 2.2
1138 o Four new functions have been written by Damien de Vienne for the
1139 graphical exploration of large trees (cophyloplot, subtrees,
1140 subtreeplot), and to return the graphical coordinates of tree
1143 o The new functions corPagel and corBlomberg implement the Pagel's
1144 "lambda" and Blomberg et al.'s "ACDC" correlation structures.
1146 o chronopl() has been improved and gains several options: see its
1147 help page for details.
1149 o boot.phylo() has now an option 'trees' to possibly return the
1150 bootstraped trees (the default is FALSE).
1152 o prop.part() has been improved and should now be faster in all
1158 o read.dna() failed if "?" occurred in the first 10 sites of the
1161 o The x/y aspect of the plot is now respected when plotting a
1162 circular tree (type = "r" or "f").
1164 o Drawing the tip labels sometimes failed when plotting circular
1167 o zoom() failed when tip labels were used instead of their numbers
1168 (thanks to Yan Wong for the fix).
1170 o drop.tip() failed with some trees (fixed by Yan Wong).
1172 o seg.sites() failed with a list.
1174 o consensus() failed in some cases. The function has been improved
1175 as well and is faster.
1179 CHANGES IN APE VERSION 2.1-3
1184 o A bug in read.nexus() made the Windows R-GUI crash.
1186 o An error was fixed in the computation of ancestral character
1187 states by generalized least squares in ace().
1189 o di2multi() did not modify node labels correctly.
1191 o multi2di() failed if the tree had its attribute "order" set to

1201 o There three new methods for the "multiPhylo" class: str, $,
1204 o root() gains the options 'node' and 'resolve.root'
1205 (FALSE by default) as well as its code being improved.
1207 o mltt.plot() has now an option 'log' used in the same way
1208 than in plot.default().
1213 o mltt.plot() failed to display the legend with an unnamed
1216 o nodelabels() with pies now correcly uses the argument
1217 'cex' to draw symbols of different sizes (which has
1218 worked already for thermometers).
1220 o read.nexus() generally failed to read very big files.
1225 o The argument 'family' of compar.gee() can now be a function
1226 as well as a character string.
1228 o read.tree() and read.nexus() now return an unnamed list if
1229 'tree.names = NULL'.
1231 o read.nexus() now returns a modified object of class "multiPhylo"
1232 when there is a TRANSLATE block in the NEXUS file: the individual
1233 trees have no 'tip.label' vector, but the list has a 'TipLabel'
1234 attribute. The new methods '$' and '[[' set these elements
1235 correctly when extracting trees.
1239 CHANGES IN APE VERSION 2.1-1
1244 o The new function rmtree generates lists of random trees.
1246 o rcoal() now generates a genuine coalescent tree by default
1247 (thanks to Vladimir Minin for the code).
1252 o nuc.div() returned an incorrect value with the default
1253 pairwise.deletion = FALSE.
1258 o The internal codes of bionj(), fastme.bal(), and fastme.ols()
1259 have been improved so that they are stabler and faster.
1261 o R packages used by ape are now loaded silently; lattice and gee
1262 are loaded only when needed.
1266 CHANGES IN APE VERSION 2.1
1271 o The new function identify.phylo identifies clades on a plotted
1272 tree using the mouse.
1274 o It is now possible to subset a list of trees (object of class
1275 "multiPhylo") with "[" while keeping its class correct.
1277 o The new function as.DNAbin.alignment converts DNA sequences
1278 stored in the "alignment" format of the package seqinr into
1279 an object of class "DNAbin".
1281 o The new function weight.taxo2 helps to build similarity matrices
1282 given two taxonomic levels (usually called by other functions).
1284 o write.tree() can now take a list of trees (class "multiPhylo")
1285 as its main argument.
1287 o plot.correlogram() and plot.correlogramList() have been
1288 improved, and gain several options (see the help page for
1289 details). A legend is now plotted by default.
1294 o dist.dna() returned some incorrect values with `model = "JC69"'
1295 and `pairwise.deletion = TRUE'. This affected only the
1296 distances involving sequences with missing values. (Thanks
1297 to Bruno Toupance for digging this bug out.)
1299 o write.tree() failed with some trees: this is fixed by removing
1300 the `multi.line' option (trees are now always printed on a
1303 o read.nexus() did not correctly detect trees with multiple root
1304 edges (see OTHER CHANGES).
1309 o The code of mlphylo() has been almost entirely rewritten, and
1310 should be much stabler. The options have been also greatly
1311 simplified (see ?mlphylo and ?DNAmodel for details).
1313 o The internal function nTips has been renamed klastorin_nTips.
1315 o The code of is.ultrametric() contained redundancies and has
1318 o The code of Moran.I() and of correlogram.formula() have been
1321 o read.tree() and read.nexus() now return an error when trying to
1322 read a tree with multiple root edges (see BUG FIXES). The
1323 correction applied in previous version did not work in all
1326 o The class c("multi.tree", "phylo") has been renamed
1332 o There is now a vignette in ape: see vignette("MoranI", "ape").
1335 DEPRECATED & DEFUNCT
1337 o as.matching() and as.phylo.matching() do not support branch
1340 o correlogram.phylo() and discrete.dist() have been removed.
1344 CHANGES IN APE VERSION 2.0-2
1349 o The new function matexpo computes the exponential of a square
1352 o The new function unique.multi.tree removes duplicate trees from
1355 o yule() has a new option `use.root.edge = FALSE' that specifies
1356 to ignore, by default, the root edge of the tree if it exists.
1361 o which.edge() failed when the index of a single terminal edge was
1364 o In diversi.time(), the values returned for model C were
1367 o A bug was fixed in yule() that affected the calculation of the
1368 likelihood in the presence of ties in the branching times.
1370 o There was a bug in the C function mat_expo4x4 affecting the
1371 calculations of the transition probabilities for models HKY and
1374 o A small bug was fixed in as.matrix.DNAbin (thanks to James
1377 o rtree() did not `shuffle' the tip labels by default, so only a
1378 limited number of labelled topologies could be generated.
1382 CHANGES IN APE VERSION 2.0-1
1387 o The three new functions bionj, fastme.ols, and fastme.bal
1388 perform phylogeny estimation by the BIONJ and fastME methods in
1389 OLS and balanced versions. This is a port to R of previous
1390 previous programs done by Vincent Lefort.
1392 o The new function chronoMPL performs molecular dating with the
1393 mean path lengths method of Britton et al. (2002, Mol. Phyl.
1396 o The new function rotate, contributed by Christoph Heibl, swaps
1397 two clades connected to the same node. It works also with
1398 multichotomous nodes.
1400 o The new `method' as.matrix.DNAbin() may be used to convert
1401 easily DNA sequences stored in a list into a matrix while
1402 keeping the names and the class.
1407 o chronopl() failed when some branch lengths were equal to zero:
1408 an error message is now returned.
1410 o di2multi() failed when there was a series of consecutive edges
1415 CHANGES IN APE VERSION 1.10-2
1420 o plot.phylo() can now plot circular trees: the option is type =
1421 "fan" or type = "f" (to avoid the ambiguity with type = "c").
1423 o prop.part() has a new option `check.labels = FALSE' which allows
1424 to considerably speed-up the calculations of bipartitions. As a
1425 consequence, calculations of bootstrap values with boot.phylo()
1426 should be much faster.
1431 o read.GenBank() did not return correctly the list of species as
1432 from ape 1.10: this is fixed in this version
1434 o Applying as.phylo() on a tree of class "phylo" failed: the
1435 object is now returned unchanged.
1439 CHANGES IN APE VERSION 1.10-1
1444 o The three new functions Ntip, Nnode, and Nedge return, for a
1445 given tree, the number of tips, nodes, or edges, respectively.
1450 o read.nexus() did not set correctly the class of the returned
1451 object when reading multiple trees.
1453 o mllt.plot() failed with objects of class c("multi.tree",
1456 o unroot() did not work correctly in most cases.
1458 o reorder.phylo() made R freeze in some occasions.
1460 o Plotting a tree in pruningwise order failed.
1462 o When plotting an unrooted tree, the tip labels where not all
1463 correctly positioned if the option `cex' was used.
1467 CHANGES IN APE VERSION 1.10
1472 o Five new `method' functions have been introduced to manipulate
1473 DNA sequences in binary format (see below).
1475 o Three new functions have been introduced to convert between the
1476 new binary and the character formats.
1478 o The new function as.alignment converts DNA sequences stored as
1479 single characters into the class "alignment" used by the package
1482 o read.dna() and read.GenBank() have a new argument `as.character'
1483 controlling whether the sequences are returned in binary format
1489 o root() failed when the tree had node labels: this is fixed.
1491 o plot.phylo() did not correctly set the limits on the y-axis with
1492 the default setting: this is fixed.
1494 o dist.dna() returned a wrong result for the LogDet, paralinear,
1495 and BH87 models with `pairwise.deletion = TRUE'.
1500 o DNA sequences are now internally stored in a binary format. See
1501 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1502 details. Most functions analyzing DNA functions have been
1503 modified accordingly and are now much faster (dist.dna is now
1504 ca. 60 times faster).
1508 CHANGES IN APE VERSION 1.9-4
1513 o A bug was fixed in edgelabels().
1515 o as.phylo.hclust() did not work correctly when the object of
1516 class "hclust" has its labels set to NULL: the returned tree has
1517 now its tip labels set to "1", "2", ...
1519 o consensus could fail if some tip labels are a subset of others
1520 (e.g., "a" and "a_1"): this is now fixed.
1522 o mlphylo() failed in most cases if some branch lengths of the
1523 initial tree were greater than one: an error message is now
1526 o mlphylo() failed in most cases when estimating the proportion of
1527 invariants: this is fixed.
1531 CHANGES IN APE VERSION 1.9-3
1536 o The new function edgelabels adds labels on the edge of the tree
1537 in the same way than nodelabels or tiplabels.
1542 o multi2di() did not handle correctly branch lengths with the
1543 default option `random = TRUE': this is now fixed.
1545 o A bug was fixed in nuc.div() when using pairwise deletions.
1547 o A bug occurred in the analysis of bipartitions with large
1548 numbers of large trees, with consequences on prop.part,
1549 prop.clades, and boot.phylo.
1551 o The calculation of the Billera-Holmes-Vogtmann distance in
1552 dist.topo was wrong: this has been fixed.
1556 CHANGES IN APE VERSION 1.9-2
1561 o The new function ladderize reorganizes the internal structure of
1562 a tree to plot them left- or right-ladderized.
1564 o The new function dist.nodes computes the patristic distances
1565 between all nodes, internal and terminal, of a tree. It replaces
1566 the option `full = TRUE' of cophenetic.phylo (see below).
1571 o A bug was fixed in old2new.phylo().
1573 o Some bugs were fixed in chronopl().
1575 o The edge colours were not correctly displayed by plot.phylo
1576 (thank you to Li-San Wang for the fix).
1578 o cophenetic.phylo() failed with multichotomous trees: this is
1584 o read.dna() now returns the sequences in a matrix if they are
1585 aligned (interleaved or sequential format). Sequences in FASTA
1586 format are still returned in a list.
1588 o The option `full' of cophenetic.phylo() has been removed because
1589 it could not be used from the generic.
1592 DEPRECATED & DEFUNCT
1594 o rotate() has been removed; this function did not work correctly
1599 CHANGES IN APE VERSION 1.9-1
1604 o Trees with a single tip were not read correctly in R as the
1605 element `Nnode' was not set: this is fixed.
1607 o unroot() did not set correctly the number of nodes of the
1608 unrooted tree in most cases.
1610 o read.GenBank() failed when fetching very long sequences,
1611 particularly of the BX-series.
1613 o A bug was introduced in read.tree() with ape 1.9: it has been
1618 CHANGES IN APE VERSION 1.9
1623 o There are two new print `methods' for trees of class "phylo" and
1624 lists of trees of class "multi.tree", so that they are now
1625 displayed in a compact and informative way.
1627 o There are two new functions, old2new.phylo and new2old.phylo,
1628 for converting between the old and new coding of the class
1631 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1632 LogDet ("logdet"), and paralinear ("paralin").
1634 o compute.brlen() has been extended: several methods are now
1635 available to compute branch lengths.
1637 o write.dna() can now handle matrices as well as lists.
1642 o cophenetic.phylo() sometimes returned a wrong result with
1643 multichotomous trees: this is fixed.
1645 o rotate() failed when a single tip was specified: the tree is now
1648 o ace() did not return the correct index matrix with custom
1649 models: this is fixed.
1651 o multi2di() did not work correctly when resolving multichotomies
1652 randomly: the topology was always the same, only the arrangement
1653 of clades was randomized: this is fixed. This function now
1654 accepts trees with no branch lengths.
1656 o The output of diversi.gof() was blurred by useless prints when a
1657 user distribution was specified. This has been corrected, and
1658 the help page of this function has been expanded.
1663 o The internal structure of the class "phylo" has been changed:
1664 see the document "Definition of Formats for Coding Phylogenetic
1665 Trees in R" for the details. In addition, the code of most
1666 functions has been improved.
1668 o Several functions have been improved by replacing some R codes
1669 by C codes: pic, plot.phylo, and reorder.phylo.
1671 o There is now a citation information: see citation("ape") in R.
1673 o write.tree() now does not add extra 0's to branch lengths so
1674 that 1.23 is printed "1.23" by default, not "1.2300000000".
1676 o The syntax of bind.tree() has been simplified. This function now
1677 accepts trees with no branch lengths, and handles correctly node
1680 o The option `as.numeric' of mrca() has been removed.
1682 o The unused options `format' and `rooted' of read.tree() have
1685 o The unused option `format' of write.tree() has been removed.
1687 o The use of node.depth() has been simplified.
1691 CHANGES IN APE VERSION 1.8-5
1696 o Two new functions read.nexus.data() and write.nexus.data(),
1697 contributed by Johan Nylander, allow to read and write molecular
1698 sequences in NEXUS files.
1700 o The new function reorder.phylo() reorders the internal structure
1701 of a tree of class "phylo". It is used as the generic, e.g.,
1704 o read.tree() and read.nexus() can now read trees with a single
1707 o The new data set `cynipids' supplies a set of protein sequences
1713 o The code of all.equal.phylo() has been completely rewritten
1714 (thanks to Benoît Durand) which fixes several bugs.
1716 o read.tree() and read.nexus() now checks the labels of the tree
1717 to remove or substitute any characters that are illegal in the
1718 Newick format (parentheses, etc.)
1720 o A negative P-value could be returned by mantel.test(): this is
1725 CHANGES IN APE VERSION 1.8-4
1730 o The new function sh.test() computes the Shimodaira-
1733 o The new function collapse.singles() removes the nodes with a
1734 single descendant from a tree.
1736 o plot.phylo() has a new argument `tip.color' to specify the
1737 colours of the tips.
1739 o mlphylo() has now an option `quiet' to control the display of
1740 the progress of the analysis (the default is FALSE).
1745 o read.dna() did not read correctly sequences in sequential format
1746 with leading alignment gaps "-": this is fixed.
1748 o ace() returned a list with no class so that the generic
1749 functions (anova, logLik, ...) could not be used directly. This
1750 is fixed as ace() now returns an object of class "ace".
1752 o anova.ace() had a small bug when computing the number of degrees
1753 of freedom: this is fixed.
1755 o mlphylo() did not work when the sequences were in a matrix or
1756 a data frame: this is fixed.
1758 o rtree() did not work correctly when trying to simulate an
1759 unrooted tree with two tips: an error message is now issued.
1764 o The algorithm of rtree() has been changed: it is now about 40,
1765 100, and 130 times faster for 10, 100, and 1000 tips,
1770 CHANGES IN APE VERSION 1.8-3
1775 o There are four new `method' functions to be used with the
1776 results of ace(): logLik(), deviance(), AIC(), and anova().
1778 o The plot method of phymltest has two new arguments: `main' to
1779 change the title, and `col' to control the colour of the
1780 segments showing the AIC values.
1782 o ace() has a new argument `ip' that gives the initial values used
1783 in the ML estimation with discrete characters (see the examples
1784 in ?ace). This function now returns a matrix giving the indices
1785 of the estimated rates when analysing discrete characters.
1787 o nodelabels() and tiplabels() have a new argument `pie' to
1788 represent proportions, with any number of categories, as
1789 piecharts. The use of the option `thermo' has been improved:
1790 there is now no limitation on the number of categories.
1795 o mlphylo() did not work with more than two partitions: this is
1798 o root() failed if the proposed outgroup was already an outgroup
1799 in the tree: this is fixed.
1801 o The `col' argument in nodelabels() and tiplabels() was not
1802 correctly passed when `text' was used: this is fixed.
1804 o Two bugs were fixed in mlphylo(): parameters were not always
1805 correctly output, and the estimation failed in some cases.
1807 o plot.phylo() was stuck when given a tree with a single tip: this
1808 is fixed and a message error is now returned.
1810 o An error was corrected in the help page of gammaStat regarding
1811 the calculation of P-values.
1813 o Using gls() could crash R when the number of species in the tree
1814 and in the variables were different: this is fixed.
1818 CHANGES IN APE VERSION 1.8-2
1823 o The new function mlphylo() fits a phylogenetic tree by maximum
1824 likelihood from DNA sequences. Its companion function DNAmodel()
1825 is used to define the substitution model which may include
1826 partitioning. There are methods for logLik(), deviance(), and
1827 AIC(), and the summary() method has been extended to display in
1828 a friendly way the results of this model fitting. Currently, the
1829 functionality is limited to estimating the substitution and
1830 associated parameters and computing the likelihood.
1832 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1833 tests for single effects in GEE-based comparative method. A
1834 warning message is printed if there is not enough degrees of
1840 o An error message was sometimes issued by plot.multi.tree(),
1841 though with no consequence.
1845 CHANGES IN APE VERSION 1.8-1
1850 o There is a new plot method for lists of trees (objects of class
1851 "multi.tree"): it calls plot.phylo() internally and is
1852 documented on the same help page.
1857 o A bug was fixed in the C code that analyzes bipartitions: this
1858 has impact on several functions like prop.part, prop.clades,
1859 boot.phylo, or consensus.
1861 o root() did not work correctly when the specified outgroup had
1862 more than one element: this is fixed.
1864 o dist.dna() sometimes returned a warning inappropriately: this
1867 o If the distance object given to nj() had no rownames, nj()
1868 returned a tree with no tip labels: it now returns tips labelled
1869 "1", "2", ..., corresponding to the row numbers.
1874 o nj() has been slightly changed so that tips with a zero distance
1875 are first aggregated with zero-lengthed branches; the usual NJ
1876 procedure is then performed on a distance matrix without 0's.
1880 CHANGES IN APE VERSION 1.8
1885 o The new function chronopl() estimates dates using the penalized
1886 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1888 o The new function consensus() calculates the consensus tree of a
1891 o The new function evolve.phylo() simulates the evolution of
1892 continuous characters along a phylogeny under a Brownian model.
1894 o The new plot method for objects of class "ancestral" displays a
1895 tree together with ancestral values, as returned by the above
1898 o The new function as.phylo.formula() returns a phylogeny from a
1899 set of nested taxonomic variables given as a formula.
1901 o The new function read.caic() reads trees in CAIC format.
1903 o The new function tiplabels() allows to add labels to the tips
1904 of a tree using text or plotting symbols in a flexible way.
1906 o The new function unroot() unroots a phylogeny.
1908 o multi2di() has a new option, `random', which specifies whether
1909 to resolve the multichotomies randomly (the default) or not.
1911 o prop.part() now returns an object of class "prop.part" for which
1912 there are print (to display a partition in a more friendly way)
1913 and summary (to extract the numbers) methods.
1915 o plot.phylo() has a new option, `show.tip.label', specifying
1916 whether to print the labels of the tips. The default is TRUE.
1918 o The code of nj() has been replaced by a faster C code: it is now
1919 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1922 o write.nexus() now writes whether a tree is rooted or not.
1927 o Two bugs have been fixed in root(): unrooted trees are now
1928 handled corretly, and node labels are now output normally.
1930 o A bug was fixed in phymltest(): the executable couldn't be found
1933 o Three bug have been fixed in ace(): computing the likelihood of
1934 ancestral states of discrete characters failed, custom models
1935 did not work, and the function failed with a null gradient (a
1936 warning message is now returned; this latter bug was also
1937 present in yule.cov() as well and is now fixed).
1939 o pic() hanged out when missing data were present: a message error
1942 o A small bug was fixed in dist.dna() where the gamma correction
1943 was not always correctly dispatched.
1945 o plot.phylo() plotted correctly the root edge only when the tree
1946 was plotted rightwards: this works now for all directions.
1951 o dist.taxo() has been renamed as weight.taxo().
1953 o dist.phylo() has been replaced by the method cophenetic.phylo().
1955 o Various error and warning messages have been improved.
1959 CHANGES IN APE VERSION 1.7
1962 o The new function ace() estimates ancestral character states for
1963 continuous characters (with ML, GLS, and contrasts methods), and
1964 discrete characters (with ML only) for any number of states.
1966 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1967 of directional evolution for continuous characters. The user
1968 specifies the node(s) of the tree where the character optimum
1971 o The new function is.rooted() tests whether a tree (of class
1974 o The new function rcoal() generates random ultrametric trees with
1975 the possibility to specify the function that generates the
1976 inter-nodes distances.
1978 o The new function mrca() gives for all pairs of tips in a tree
1979 (and optionally nodes too) the most recent common ancestor.
1981 o nodelabels() has a new option `thermo' to plot proportions (up
1982 to three classes) on the nodes of a tree.
1984 o rtree() has been improved: it can now generate rooted or
1985 unrooted trees, and the mathematical function that generates the
1986 branch lengths may be specified by the user. The tip labels may
1987 be given directly in the call to rtree. The limit cases (n = 2,
1988 3) are now handled correctly.
1990 o dist.topo() has a new argument `method' with two choices: "PH85"
1991 for Penny and Henny's method (already available before and now
1992 the default), and "BHV01" for the geometric distance by Billera
1993 et al. (2001, Adv. Appl. Math. 27:733).
1995 o write.tree() has a new option, `digits', which specifies the
1996 number of digits to be printed in the Newick tree. By default
1997 digits = 10. The numbers are now always printed in decimal form
1998 (i.e., 1.0e-1 is now avoided).
2000 o dist.dna() can now compute the raw distances between pairs of
2001 DNA sequences by specifying model = "raw".
2003 o dist.phylo() has a new option `full' to possibly compute the
2004 distances among all tips and nodes of the tree. The default if
2010 o Several bugs were fixed in all.equal.phylo().
2012 o dist.dna() did not handle correctly gaps ("-") in alignments:
2013 they are now considered as missing data.
2015 o rotate() did not work if the tips were not ordered: this is
2018 o mantel.test() returned NA in some special cases: this is fixed
2019 and the function has been improved and is now faster.
2021 o A bug was fixed in diversi.gof() where the calculation of A² was
2024 o cherry() did not work correctly under some OSs (mainly Linux):
2027 o is.binary.tree() has been modified so that it works with both
2028 rooted and unrooted trees.
2030 o The documentation of theta.s() was not correct: this has been
2033 o plot.mst() did not work correctly: this is fixed.
2037 CHANGES IN APE VERSION 1.6
2042 o The new function dist.topo() computes the topological distances
2045 o The new function boot.phylo() performs a bootstrap analysis on
2046 phylogeny estimation.
2048 o The new functions prop.part() and prop.clades() analyse
2049 bipartitions from a series of trees.
2054 o read.GenBank() now uses the EFetch utility of NCBI instead of
2055 the usual Web interface: it is now much faster (e.g., 12 times
2056 faster to retrieve 8 sequences, 37 times for 60 sequences).
2061 o Several bugs were fixed in read.dna().
2063 o Several bugs were fixed in diversi.time().
2065 o is.binary.tree() did not work correctly if the tree has no edge
2066 lengths: this is fixed.
2068 o drop.tip() did not correctly propagated the `node.label' of a
2069 tree: this is fixed.
2073 CHANGES IN APE VERSION 1.5
2078 o Two new functions, as.matching.phylo() and as.phylo.matching(),
2079 convert objects between the classes "phylo" and "matching". The
2080 latter implements the representation of binary trees introduced by
2081 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
2082 as.matching() has been introduced as well.
2084 o Two new functions, multi2di() and di2multi(), allow to resolve
2085 and collapse multichotomies with branches of length zero.
2087 o The new function nuc.div() computes the nucleotide diversity
2088 from a sample a DNA sequences.
2090 o dist.dna() has been completely rewritten with a much faster
2091 (particularly for large data sets) C code. Eight models are
2092 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
2093 option `method' has been renamed `model'). Computation of variance
2094 is available for all models. A gamma-correction is possible for
2095 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
2096 to remove sites with missing data on a pairwise basis. The option
2097 `GCcontent' has been removed.
2099 o read.GenBank() has a new option (species.names) which specifies
2100 whether to return the species names of the organisms in addition
2101 to the accession numbers of the sequences (this is the default
2104 o write.nexus() can now write several trees in the same NEXUS file.
2106 o drop.tip() has a new option `root.edge' that allows to specify the
2107 new root edge if internal branches are trimmed.
2112 o as.phylo.hclust() failed if some labels had parentheses: this
2115 o Several bugs were fixed in all.equal.phylo(). This function now
2116 returns the logical TRUE if the trees are identical but with
2117 different representations (a report was printed previously).
2119 o read.GenBank() did not correctly handle ambiguous base codes:
2125 o birthdeath() now returns an object of class "birthdeath" for
2126 which there is a print method.
2130 CHANGES IN APE VERSION 1.4
2135 o The new function nj() performs phylogeny estimation with the
2136 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
2139 o The new function which.edge() identifies the edges of a tree
2140 that belong to a group specified as a set of tips.
2142 o The new function as.phylo.phylog() converts an object of class
2143 "phylog" (from the package ade4) into an object of class
2146 o The new function axisPhylo() draws axes on the side of a
2149 o The new function howmanytrees() calculates the number of trees
2150 in different cases and giving a number of tips.
2152 o write.tree() has a new option `multi.line' (TRUE by default) to
2153 write a Newick tree on several lines rather than on a single
2156 o The functionalities of zoom() have been extended. Several
2157 subtrees can be visualized at the same time, and they are marked
2158 on the main tree with colors. The context of the subtrees can be
2159 marked with the option `subtree' (see below).
2161 o drop.tip() has a new option `subtree' (FALSE by default) which
2162 specifies whether to output in the tree how many tips have been
2165 o The arguments of add.scale.bar() have been redefined and have
2166 now default values (see ?add.scale.bar for details). This
2167 function now works even if the plotted tree has no edge length.
2169 o plot.phylo() can now plot radial trees, but this does not take
2170 edge lengths into account.
2172 o In plot.phylo() with `type = "phylogram"', if the values of
2173 `edge.color' and `edge.width' are identical for sister-branches,
2174 they are propagated to the vertical line that link them.
2179 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
2180 crashing. This is fixed.
2182 o In plot.phylo(), the options `edge.color' and `edge.width' are
2183 now properly recycled; their default values are now "black" and
2186 o A bug has been fixed in write.nexus().
2191 o The function node.depth.edgelength() has been removed and
2192 replaced by a C code.
2196 CHANGES IN APE VERSION 1.3-1
2201 o The new function nodelabels() allows to add labels to the nodes
2202 of a tree using text or plotting symbols in a flexible way.
2204 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
2205 numeric values specifying the lower and upper limits on the x-
2206 and y-axes. This allows to leave some space on any side of the
2207 tree. If a single value is given, this is taken as the upper
2212 CHANGES IN APE VERSION 1.3
2217 o The new function phymltest() calls the software PHYML and fits
2218 28 models of DNA sequence evolution. There are a print method to
2219 display likelihood and AIC values, a summary method to compute
2220 the hierarchical likelihood ratio tests, and a plot method to
2221 display graphically the AIC values of each model.
2223 o The new function yule.cov() fits the Yule model with covariates,
2224 a model where the speciation rate is affected by several species
2225 traits through a generalized linear model. The parameters are
2226 estimated by maximum likelihood.
2228 o Three new functions, corBrownian(), corGrafen(), and
2229 corMartins(), compute the expected correlation structures among
2230 species given a phylogeny under different models of evolution.
2231 These can be used for GLS comparative phylogenetic methods (see
2232 the examples). There are coef() and corMatrix() methods and an
2233 Initialize.corPhyl() function associated.
2235 o The new function compar.cheverud() implements Cheverud et al.'s
2236 (1985; Evolution 39:1335) phylogenetic comparative method.
2238 o The new function varcomp() estimates variance components; it has
2241 o Two new functions, panel.superpose.correlogram() and
2242 plot.correlogramList(), allow to plot several phylogenetic
2245 o The new function node.leafnumber() computes the number of leaves
2246 of a subtree defined by a particular node.
2248 o The new function node.sons() gets all tags of son nodes from a
2251 o The new function compute.brlen() computes the branch lengths of
2252 a tree according to a specified method.
2254 o plot.phylo() has three new options: "cex" controls the size of
2255 the (tip and node) labels (thus it is no more needed to change
2256 the global graphical parameter), "direction" which allows to
2257 plot the tree rightwards, leftwards, upwards, or downwards, and
2258 "y.lim" which sets the upper limit on the y-axis.
2263 o Some functions which try to match tip labels and names of
2264 additional data (e.g. vector) are likely to fail if there are
2265 typing or syntax errors. If both series of names do not perfectly
2266 match, they are ignored and a warning message is now issued.
2267 These functions are bd.ext, compar.gee, pic. Their help pages
2268 have been clarified on this point.
2272 CHANGES IN APE VERSION 1.2-7
2277 o The new function root() reroots a phylogenetic tree with respect
2278 to a specified outgroup.
2280 o The new function rotate() rotates an internal branch of a tree.
2282 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
2283 trees) controls the display of the tip labels in unrooted trees.
2284 This display has been greatly improved: the tip labels are now not
2285 expected to overlap with the tree (particularly if lab4ut =
2286 "axial"). In all cases, combining appropriate values of "lab4ut"
2287 and the font size (via "par(cex = )") should result in readable
2288 unrooted trees. See ?plot.phylo for some examples.
2290 o In drop.tip(), the argument `tip' can now be numeric or character.
2295 o drop.tip() did not work correctly with trees with no branch
2296 lengths: this is fixed.
2298 o A bug in plot.phylo(..., type = "unrooted") made some trees being
2299 plotted with some line crossings: this is now fixed.
2303 CHANGES IN APE VERSION 1.2-6
2308 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
2309 correlogram.phylo, dist.taxo, plot.correlogram) have been added
2310 to implement comparative methods with an autocorrelation approach.
2312 o A new data set describing some life history traits of Carnivores
2318 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
2323 o When plotting a tree with plot.phylo(), the new default of the
2324 option `label.offset' is now 0, so the labels are always visible.
2328 CHANGES IN APE VERSION 1.2-5
2333 o The new function bd.ext() fits a birth-death model with combined
2334 phylogenetic and taxonomic data, and estimates the corresponding
2335 speciation and extinction rates.
2340 o The package gee is no more required by ape but only suggested
2341 since only the function compar.gee() calls gee.
2345 CHANGES IN APE VERSION 1.2-4
2350 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
2351 and lines.popsize) implementing a new approach for inferring the
2352 demographic history from genealogies using a reversible jump
2353 MCMC have been introduced.
2355 o The unit of time in the skyline plot and in the new plots can
2356 now be chosen to be actual years, rather than substitutions.
2360 CHANGES IN APE VERSION 1.2-3
2365 o The new function rtree() generates a random binary tree with or
2366 without branch lengths.
2368 o Two new functions for drawing lineages-through-time (LTT) plots
2369 are provided: ltt.lines() adds a LTT curve to an existing plot,
2370 and mltt.plot() does a multiple LTT plot giving several trees as
2371 arguments (see `?ltt.plot' for details).
2376 o Some taxon names made R crashing when calling as.phylo.hclust():
2379 o dist.dna() returned an error with two identical DNA sequences
2380 (only using the Jukes-Cantor method returned 0): this is fixed.
2385 o The function dist.phylo() has been re-written using a different
2386 algorithm: it is now about four times faster.
2388 o The code of branching.times() has been improved: it is now about
2393 CHANGES IN APE VERSION 1.2-2
2398 o The new function seg.sites() finds the segregating sites in a
2399 sample of DNA sequences.
2404 o A bug introduced in read.tree() and in read.nexus() with version
2407 o A few errors were corrected and a few examples were added in the
2412 CHANGES IN APE VERSION 1.2-1
2417 o plot.phylo() can now draw the edge of the root of a tree if it
2418 has one (see the new option `root.edge', its default is FALSE).
2423 o A bug was fixed in read.nexus(): files with semicolons inside
2424 comment blocks were not read correctly.
2426 o The behaviour of read.tree() and read.nexus() was corrected so
2427 that tree files with badly represented root edges (e.g., with
2428 an extra pair of parentheses, see the help pages for details)
2429 are now correctly represented in the object of class "phylo";
2430 a warning message is now issued.
2434 CHANGES IN APE VERSION 1.2
2439 o plot.phylo() has been completely re-written and offers several
2440 new functionalities. Three types of trees can now be drawn:
2441 phylogram (as previously), cladogram, and unrooted tree; in
2442 all three types the branch lengths can be drawn using the edge
2443 lengths of the phylogeny or not (e.g., if the latter is absent).
2444 The vertical position of the nodes can be adjusted with two
2445 choices (see option `node.pos'). The code has been re-structured,
2446 and two new functions (potentially useful for developpers) are
2447 documented separately: node.depth.edgelength() and node.depth();
2448 see the respective help pages for details.
2450 o The new function zoom() allows to explore very large trees by
2451 focusing on a small portion of it.
2453 o The new function yule() fits by maximum likelihood the Yule model
2454 (birth-only process) to a phylogenetic tree.
2456 o Support for writing DNA sequences in FASTA format has been
2457 introduced in write.dna() (support for reading sequences in
2458 this format was introduced in read.dna() in version 1.1-2).
2459 The function has been completely re-written, fixing some bugs
2460 (see below); the default behaviour is no more to display the
2461 sequences on the standard output. Several options have been
2462 introduced to control the sequence printing in a flexible
2463 way. The help page has been extended.
2465 o A new data set is included: a supertree of bats in NEXUS format.
2470 o In theta.s(), the default of the option `variance' has
2471 been changed to `FALSE' (as was indicated in the help page).
2473 o Several bugs were fixed in the code of all.equal.phylo().
2475 o Several bugs were fixed in write.dna(), particularly this
2476 function did not work with `format = "interleaved"'.
2478 o Various errors were corrected in the help pages.
2483 o The argument names of as.hclust.phylo() have been changed
2484 from "(phy)" to "(x, ...)" to conform to the definition of
2485 the corresponding generic function.
2487 o gamma.stat() has been renamed gammaStat() to avoid confusion
2488 since gamma() is a generic function.
2492 CHANGES IN APE VERSION 1.1-3
2497 o base.freq() previously did not return a value of 0 for
2498 bases absent in the data (e.g., a vector of length 3 was
2499 returned if one base was absent). This is now fixed (a
2500 vector of length 4 is always returned).
2502 o Several bugs were fixed in read.nexus(), including that this
2503 function did not work in this absence of a "TRANSLATE"
2504 command in the NEXUS file, and that the commands were
2509 CHANGES IN APE VERSION 1.1-2
2514 o The Tamura and Nei (1993) model of DNA distance is now implemented
2515 in dist.dna(): five models are now available in this function.
2517 o A new data set is included: a set of 15 sequences of the
2518 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2524 o A bug in read.nexus() was fixed.
2526 o read.dna() previously did not work correctly in most cases.
2527 The function has been completely re-written and its help page
2528 has been considerably extended (see ?read.dna for details).
2529 Underscores (_) in taxon names are no more replaced with
2530 spaces (this behaviour was undocumented).
2532 o A bug was fixed in write.dna().
2536 CHANGES IN APE VERSION 1.1-1
2541 o A bug in read.tree() introduced in APE 1.1 was fixed.
2543 o A bug in compar.gee() resulted in an error when trying to fit
2544 a model with `family = "binomial"'. This is now fixed.
2548 CHANGES IN APE VERSION 1.1
2553 o The Klastorin (1982) method as suggested by Misawa and Tajima
2554 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2555 on the basis of phylogenetic trees has been implemented (see
2556 the function klastorin()).
2558 o Functions have been added to convert APE's "phylo" objects in
2559 "hclust" cluster objects and vice versa (see the help page of
2560 as.phylo for details).
2562 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2563 are introduced for the estimation of absolute evolutionary rates
2564 (ratogram) and dated clock-like trees (chronogram) from
2565 phylogenetic trees using the non-parametric rate smoothing approach
2566 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2568 o A summary method is now provided printing a summary information on a
2569 phylogenetic tree with, for instance, `summary(tree)'.
2571 o The behaviour of read.tree() was changed so that all spaces and
2572 tabulations in tree files are now ignored. Consequently, spaces in tip
2573 labels are no more allowed. Another side effect is that read.nexus()
2574 now does not replace the underscores (_) in tip labels with spaces
2575 (this behaviour was undocumented).
2577 o The function plot.phylo() has a new option (`underscore') which
2578 specifies whether the underscores in tip labels should be written on
2579 the plot as such or replaced with spaces (the default).
2581 o The function birthdeath() now computes 95% confidence intervals of
2582 the estimated parameters using profile likelihood.
2584 o Three new data sets are included: a gene tree estimated from 36
2585 landplant rbcL sequences, a gene tree estimated from 32 opsin
2586 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2591 o A bug was fixed in dist.gene() where nothing was returned.
2593 o A bug in plot.mst() was fixed.
2595 o A bug in vcv.phylo() resulted in false correlations when the
2596 option `cor = TRUE' was used (now fixed).
2600 CHANGES IN APE VERSION 1.0
2605 o Two new functions, read.dna() and write.dna(), read/write in a file
2606 DNA sequences in interleaved or in sequential format.
2608 o Two new functions, read.nexus() and write.nexus(), read/write trees
2611 o The new function bind.tree() allows to bind two trees together,
2612 possibly handling root edges to give internal branches.
2614 o The new function drop.tip() removes the tips in a phylogenetic tree,
2615 and trims (or not) the corresponding internal branches.
2617 o The new function is.ultrametric() tests if a tree is ultrametric.
2619 o The function plot.phylo() has more functionalities such as drawing the
2620 branches with different colours and/or different widths, showing the
2621 node labels, controling the position and font of the labels, rotating
2622 the labels, and controling the space around the plot.
2624 o The function read.tree() can now read trees with no branch length,
2625 such as "(a,b),c);". Consequently, the element `edge.length' in
2626 objects of class "phylo" is now optional.
2628 o The function write.tree() has a new default behaviour: if the default
2629 for the option `file' is used (i.e. file = ""), then a variable of
2630 mode character containing the tree in Newick format is returned which
2631 can thus be assigned (e.g., tree <- write.tree(phy)).
2633 o The function read.tree() has a new argument `text' which allows
2634 to read the tree in a variable of mode character.
2636 o A new data set is included: the phylogenetic relationships among
2637 the orders of birds from Sibley and Ahlquist (1990).
2641 CHANGES IN APE VERSION 0.2-1
2646 o Several bugs were fixed in the help pages.
2650 CHANGES IN APE VERSION 0.2
2655 o The function write.tree() writes phylogenetic trees (objects of class
2656 "phylo") in an ASCII file using the Newick parenthetic format.
2658 o The function birthdeath() fits a birth-death model to branching times
2659 by maximum likelihood, and estimates the corresponding speciation and
2662 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2665 o The function is.binary.tree() tests whether a phylogeny is binary.
2667 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2668 as well as some methods are introduced.
2670 o Several functions, including some generics and methods, for computing
2671 skyline plot estimates (classic and generalized) of effective
2672 population size through time are introduced and replace the function
2673 skyline.plot() in version 0.1.
2675 o Two data sets are now included: the phylogenetic relationships among
2676 the families of birds from Sibley and Ahlquist (1990), and an
2677 estimated clock-like phylogeny of HIV sequences sampled in the
2678 Democratic Republic of Congo.
2681 DEPRECATED & DEFUNCT
2683 o The function skyline.plot() in ape 0.1 has been deprecated and
2684 replaced by more elaborate functions (see above).
2689 o Two important bugs were fixed in plot.phylo(): phylogenies with
2690 multichotomies not at the root or not with only terminal branches,
2691 and phylogenies with a single node (i.e. only terminal branches)
2692 did not plot. These trees should be plotted correctly now.
2694 o Several bugs were fixed in diversi.time() in the computation of
2697 o Various errors were corrected in the help pages.
