1 CHANGES IN APE VERSION 2.5-3
6 o The new function mixedFontLabel helps to make labels with bits of
7 text to be plotted in different fonts.
9 o There are now replacement operators for [, [[, and $ for the class
10 "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They check
11 that the tip labels are the same in all trees.
13 o Objects of class "multiPhylo" can be built with c(): there are
14 methods for the classes "phylo" and "multiPhylo".
16 o The internal functions .compressTipLabel and .uncompressTipLabel are
22 o bind.tree(x, y, where, position = 0) did not work correctly if 'y'

39 o read.dna() has a new option 'as.matrix' to possibly force sequences
40 in a FASTA file to be stored in a matrix (see ?read.dna for details).
45 o as.phylo.hclust() used to multiply edge lengths by 2.
47 o A minor bug was fixed in rTraitDisc().
49 o ace() sometimes failed (parameter value was NaN and the optimisation

82 o drop.tip(), extract.clade(), root(), and bind.tree() now have an
83 'interactive' option to make the operation on a plotted tree.
85 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
86 association links; they are recycled like 'col' (which wasn't before).
91 o rTraitDisc() did not use its 'freq' argument correctly (it was
92 multiplied with the rate matrix column-wise instead of row-wise).
94 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
95 with NA values. Nothing is drawn now like with 'text' or 'pch'.
96 The same bug occurred with the 'pie' option.
98 o A bug was fixed in compar.ou() and the help page was clarified.
100 o bind.tree() has been rewritten fixing several bugs and making it
103 o plot.phylo(type = "p") sometimes failed to colour correctly the
104 vertical lines representing the nodes.
106 o plot.phylo(direction = "l", x.lim = 30) failed to plot the branches
107 in the correct direction though the tip labels were displayed
113 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
114 the sequences are correctly stored (in a list for c, in a matrix
115 for the two other functions).
119 CHANGES IN APE VERSION 2.5
124 o The new function parafit by Pierre Legendre tests for the
125 coevolution between hosts and parasites. It has a companion
126 function, pcoa, that does principal coordinate decomposition.
127 The latter has a biplot method.
129 o The new function lmorigin by Pierre Legendre performs multiple
130 regression through the origin with testing by permutation.
132 o The new functions rTraitCont and rTraitDisc simulate continuous and
133 discrete traits under a wide range of evolutionary models.
135 o The new function delta.plot does a delta plot following Holland et
136 al. (2002, Mol. Biol. Evol. 12:2051).
138 o The new function edges draws additional branches between any nodes
139 and/or tips on a plotted tree.
141 o The new function fancyarrows enhances arrows from graphics with
142 triangle and harpoon heads; it can be called from edges().
144 o add.scale.bar() has a new option 'ask' to draw interactively.
146 o The branch length score replaces the geodesic distance in dist.topo.
148 o Three new data sets are included: the gopher-lice data (gopher.D),
149 SO2 air pollution in 41 US cities (lmorigin.ex1, from Sokal &
150 Rohlf 1995), and some host-parasite specificity data
151 (lmorigin.ex2, from Legendre & Desdevises 2009).
156 o add.scale.bar() drew the bar outside the plotting region with the
157 default options with unrooted or radial trees.

175 o rtree() and rcoal() now accept a numeric vector for the 'br'
178 o vcv() is a new generic function with methods for the classes "phylo"
179 and "corPhyl" so that it is possible to calculate the var-cov matrix
180 for "transformation models". vcv.phylo() can still be used for trees
181 of class "phylo"; its argument 'cor' has been renamed 'corr'.
186 o bind.tree() failed when 'y' had no root edge.
188 o read.nexus() shuffled tip labels when the trees have no branch
189 lengths and there is a TRANSLATE block.
191 o read.nexus() does not try to translate node labels if there is a
192 translation table in the NEXUS file. See ?read.nexus for a
193 clarification on this behaviour.
195 o plot.multiPhylo() crashed R when plotting a list of trees with
196 compressed tip labels.
198 o write.nexus() did not translate the taxa names when asked for.
200 o plot.phylo(type = "fan") did not rotate the tip labels correctly
201 when the tree has branch lengths.

204 negative (which resulted in an error).
206 o nj() crashed with NA/NaN in the distance matrix: an error in now
211 CHANGES IN APE VERSION 2.4
216 o base.freq() has a new option 'freq' to return the counts; the
217 default is still to return the proportions.
222 o seg.sites() did not handle ambiguous nucleotides correctly: they
225 o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
226 the tree: the argument is now ignored.

234 o Trying to plot a tree with a single tip now returns NULL with a
235 warning (it returned an error previously).
237 o The way lines representing nodes are coloured in phylograms has
238 been modified (as well as their widths and types) following some
239 users' request; this is only for dichotomous nodes.
241 o The argument 'adj' in [node][tip][edge]labels() now works when
242 using 'pie' or 'thermo'.
244 o A more informative message error is now returned by dist.dna() when
245 'model' is badly specified (partial matching of this argument is
248 o Deprecated functions are now listed in a help page: see
249 help("ape-defunct") with the quotes.

255 theta.s have been moved from ape to pegas.
257 o The functions mlphylo, DNAmodel and sh.test have been removed.

299 o extract.clade() sometimes included too many edges.
301 o vcv.phylo() did not work correctly when the tree is in
304 o nj() did not handle correctly distance matrices with many 0's.
305 The code has also been significantly improved: 7, 70, 160 times
306 faster with n = 100, 500, 1000, respectively.
310 CHANGES IN APE VERSION 2.3-1
315 o The new function is.monophyletic tests the monophyly of a group.
317 o There is now a c() method for lists of class "DNAbin".

320 corrected with respect to this change.
322 o drop.tip() has a new option 'rooted' to force (or not) a tree
323 to be treated as (un)rooted.
328 o dist.gene() failed on most occasions with the default
329 pairwise.deletion = FALSE.
331 o read.tree() failed to read correctly the tree name(s).
333 o boot.phylo() now treats correctly data frames.
335 o del.gaps() did not copy the rownames of a matrix.

385 o phymltest() has been updated to work with PhyML 3.0.1.
390 o drop.tip() shuffled tip labels in some cases.

429 specifying a node number or label.
431 o fastme.bal() has two new options 'spr' and 'tbr' to perform tree
432 operations of the same names.
434 o dist.dna() can now return the number of site differences by
435 specifying model="N".
440 o chronopl() did not work with CV = TRUE.
442 o read.nexus() did not work correctly in some situations (trees on
443 multiple lines with different numbers of lines and/or with
444 comments inserted within the trees).

447 the number of lineages with non-binary trees.
452 o ape has now a namespace.
454 o drop.tip() has been improved: it should be much faster and work
455 better in some cases (e.g., see the example in ?zoom).

464 o dist.gene() has been substantially improved and gains an option
467 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
473 o prop.part() failed with a single tree with the default option
474 'check.labels = TRUE'.
476 o summary.DNAbin() failed to display correctly the summary of
477 sequence lengths with lists of sequences of 10,000 bases or more
478 (because summary.default uses 4 significant digits by default).
480 o read.nexus() failed to read a file with a single tree with line
481 breaks in the Newick string.
483 o del.gaps() returned a list of empty sequences when there were no

490 'append', whereas the option 'path2exec' has been removed.
492 o rbind.DNAbin() and cbind.DNAbin() now accept a single matrix
493 which is returned unchanged (instead of an error).
495 o The data sets bird.orders and bird.families are now stored as
496 Newick strings; i.e., the command data(bird.orders) calls
501 CHANGES IN APE VERSION 2.2-1
506 o The new function makeLabel() helps to modify labels of trees,
507 lists of trees, or DNA sequences, with several utilities to
508 truncate and/or make them unique, substituting some
509 characters, and so on.
511 o The new function del.gaps() removes insertion gaps ("-") in a
512 set of DNA sequences.

544 o The option 'check.labels' of consensus() and prop.part() is now
547 o write.dna() now does not truncate names to 10 characters with
552 CHANGES IN APE VERSION 2.2
557 o Four new functions have been written by Damien de Vienne for the
558 graphical exploration of large trees (cophyloplot, subtrees,
559 subtreeplot), and to return the graphical coordinates of tree

583 o Drawing the tip labels sometimes failed when plotting circular
586 o zoom() failed when tip labels were used instead of their numbers
587 (thanks to Yan Wong for the fix).
589 o drop.tip() failed with some trees (fixed by Yan Wong).
591 o seg.sites() failed with a list.
593 o consensus() failed in some cases. The function has been improved
594 as well and is faster.
598 CHANGES IN APE VERSION 2.1-3
603 o A bug in read.nexus() made the Windows R-GUI crash.
605 o An error was fixed in the computation of ancestral character
606 states by generalized least squares in ace().

624 (FALSE by default) as well as its code being improved.
626 o mltt.plot() has now an option 'log' used in the same way
627 than in plot.default().
632 o mltt.plot() failed to display the legend with an unnamed
635 o nodelabels() with pies now correcly uses the argument
636 'cex' to draw symbols of different sizes (which has
637 worked already for thermometers).
639 o read.nexus() generally failed to read very big files.
644 o The argument 'family' of compar.gee() can now be a function
645 as well as a character string.
647 o read.tree() and read.nexus() now return an unnamed list if
650 o read.nexus() now returns a modified object of class "multiPhylo"
651 when there is a TRANSLATE block in the NEXUS file: the individual
652 trees have no 'tip.label' vector, but the list has a 'TipLabel'
653 attribute. The new methods '$' and '[[' set these elements
654 correctly when extracting trees.
658 CHANGES IN APE VERSION 2.1-1
663 o The new function rmtree generates lists of random trees.
665 o rcoal() now generates a genuine coalescent tree by default
666 (thanks to Vladimir Minin for the code).
671 o nuc.div() returned an incorrect value with the default
672 pairwise.deletion = FALSE.
677 o The internal codes of bionj(), fastme.bal(), and fastme.ols()
678 have been improved so that they are stabler and faster.
680 o R packages used by ape are now loaded silently; lattice and gee

685 CHANGES IN APE VERSION 2.1
690 o The new function identify.phylo identifies clades on a plotted
691 tree using the mouse.
693 o It is now possible to subset a list of trees (object of class

704 as its main argument.
706 o plot.correlogram() and plot.correlogramList() have been
707 improved, and gain several options (see the help page for
708 details). A legend is now plotted by default.
713 o dist.dna() returned some incorrect values with `model = "JC69"'
714 and `pairwise.deletion = TRUE'. This affected only the
715 distances involving sequences with missing values. (Thanks
716 to Bruno Toupance for digging this bug out.)
718 o write.tree() failed with some trees: this is fixed by removing
719 the `multi.line' option (trees are now always printed on a
722 o read.nexus() did not correctly detect trees with multiple root
723 edges (see OTHER CHANGES).
728 o The code of mlphylo() has been almost entirely rewritten, and

763 CHANGES IN APE VERSION 2.0-2
768 o The new function matexpo computes the exponential of a square
771 o The new function unique.multi.tree removes duplicate trees from

775 to ignore, by default, the root edge of the tree if it exists.
780 o which.edge() failed when the index of a single terminal edge was
783 o In diversi.time(), the values returned for model C were
786 o A bug was fixed in yule() that affected the calculation of the
787 likelihood in the presence of ties in the branching times.
789 o There was a bug in the C function mat_expo4x4 affecting the
790 calculations of the transition probabilities for models HKY and
793 o A small bug was fixed in as.matrix.DNAbin (thanks to James

797 limited number of labelled topologies could be generated.
801 CHANGES IN APE VERSION 2.0-1
806 o The three new functions bionj, fastme.ols, and fastme.bal
807 perform phylogeny estimation by the BIONJ and fastME methods in
808 OLS and balanced versions. This is a port to R of previous
809 previous programs done by Vincent Lefort.
811 o The new function chronoMPL performs molecular dating with the
812 mean path lengths method of Britton et al. (2002, Mol. Phyl.
815 o The new function rotate, contributed by Christoph Heibl, swaps
816 two clades connected to the same node. It works also with
817 multichotomous nodes.
819 o The new `method' as.matrix.DNAbin() may be used to convert
820 easily DNA sequences stored in a list into a matrix while
821 keeping the names and the class.
826 o chronopl() failed when some branch lengths were equal to zero:
827 an error message is now returned.
829 o di2multi() failed when there was a series of consecutive edges
834 CHANGES IN APE VERSION 1.10-2
839 o plot.phylo() can now plot circular trees: the option is type =
840 "fan" or type = "f" (to avoid the ambiguity with type = "c").
842 o prop.part() has a new option `check.labels = FALSE' which allows
843 to considerably speed-up the calculations of bipartitions. As a
844 consequence, calculations of bootstrap values with boot.phylo()
845 should be much faster.
850 o read.GenBank() did not return correctly the list of species as
851 from ape 1.10: this is fixed in this version
853 o Applying as.phylo() on a tree of class "phylo" failed: the
854 object is now returned unchanged.

892 DNA sequences in binary format (see below).
894 o Three new functions have been introduced to convert between the
895 new binary and the character formats.
897 o The new function as.alignment converts DNA sequences stored as
898 single characters into the class "alignment" used by the package
901 o read.dna() and read.GenBank() have a new argument `as.character'
902 controlling whether the sequences are returned in binary format
908 o root() failed when the tree had node labels: this is fixed.
910 o plot.phylo() did not correctly set the limits on the y-axis with
911 the default setting: this is fixed.
913 o dist.dna() returned a wrong result for the LogDet, paralinear,
914 and BH87 models with `pairwise.deletion = TRUE'.
919 o DNA sequences are now internally stored in a binary format. See
920 the document "A Bit-Level Coding Scheme for Nucleotides" for the
921 details. Most functions analyzing DNA functions have been
922 modified accordingly and are now much faster (dist.dna is now
923 ca. 60 times faster).
927 CHANGES IN APE VERSION 1.9-4
932 o A bug was fixed in edgelabels().
934 o as.phylo.hclust() did not work correctly when the object of
935 class "hclust" has its labels set to NULL: the returned tree has
936 now its tip labels set to "1", "2", ...
938 o consensus could fail if some tip labels are a subset of others
939 (e.g., "a" and "a_1"): this is now fixed.
941 o mlphylo() failed in most cases if some branch lengths of the
942 initial tree were greater than one: an error message is now
945 o mlphylo() failed in most cases when estimating the proportion of
946 invariants: this is fixed.
950 CHANGES IN APE VERSION 1.9-3
955 o The new function edgelabels adds labels on the edge of the tree
956 in the same way than nodelabels or tiplabels.
961 o multi2di() did not handle correctly branch lengths with the
962 default option `random = TRUE': this is now fixed.
964 o A bug was fixed in nuc.div() when using pairwise deletions.
966 o A bug occurred in the analysis of bipartitions with large
967 numbers of large trees, with consequences on prop.part,
968 prop.clades, and boot.phylo.
970 o The calculation of the Billera-Holmes-Vogtmann distance in
971 dist.topo was wrong: this has been fixed.
975 CHANGES IN APE VERSION 1.9-2
980 o The new function ladderize reorganizes the internal structure of
981 a tree to plot them left- or right-ladderized.
983 o The new function dist.nodes computes the patristic distances
984 between all nodes, internal and terminal, of a tree. It replaces
985 the option `full = TRUE' of cophenetic.phylo (see below).
990 o A bug was fixed in old2new.phylo().
992 o Some bugs were fixed in chronopl().
994 o The edge colours were not correctly displayed by plot.phylo
995 (thank you to Li-San Wang for the fix).
997 o cophenetic.phylo() failed with multichotomous trees: this is
1003 o read.dna() now returns the sequences in a matrix if they are
1004 aligned (interleaved or sequential format). Sequences in FASTA
1005 format are still returned in a list.
1007 o The option `full' of cophenetic.phylo() has been removed because
1008 it could not be used from the generic.
1011 DEPRECATED & DEFUNCT
1013 o rotate() has been removed; this function did not work correctly
1018 CHANGES IN APE VERSION 1.9-1
1023 o Trees with a single tip were not read correctly in R as the
1024 element `Nnode' was not set: this is fixed.
1026 o unroot() did not set correctly the number of nodes of the
1027 unrooted tree in most cases.
1029 o read.GenBank() failed when fetching very long sequences,
1030 particularly of the BX-series.
1032 o A bug was introduced in read.tree() with ape 1.9: it has been
1037 CHANGES IN APE VERSION 1.9
1042 o There are two new print `methods' for trees of class "phylo" and
1043 lists of trees of class "multi.tree", so that they are now
1044 displayed in a compact and informative way.
1046 o There are two new functions, old2new.phylo and new2old.phylo,
1047 for converting between the old and new coding of the class
1050 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1051 LogDet ("logdet"), and paralinear ("paralin").
1053 o compute.brlen() has been extended: several methods are now
1054 available to compute branch lengths.
1056 o write.dna() can now handle matrices as well as lists.
1061 o cophenetic.phylo() sometimes returned a wrong result with
1062 multichotomous trees: this is fixed.
1064 o rotate() failed when a single tip was specified: the tree is now
1067 o ace() did not return the correct index matrix with custom
1068 models: this is fixed.
1070 o multi2di() did not work correctly when resolving multichotomies
1071 randomly: the topology was always the same, only the arrangement
1072 of clades was randomized: this is fixed. This function now
1073 accepts trees with no branch lengths.
1075 o The output of diversi.gof() was blurred by useless prints when a
1076 user distribution was specified. This has been corrected, and
1077 the help page of this function has been expanded.
1082 o The internal structure of the class "phylo" has been changed:
1083 see the document "Definition of Formats for Coding Phylogenetic
1084 Trees in R" for the details. In addition, the code of most
1085 functions has been improved.
1087 o Several functions have been improved by replacing some R codes
1088 by C codes: pic, plot.phylo, and reorder.phylo.
1090 o There is now a citation information: see citation("ape") in R.
1092 o write.tree() now does not add extra 0's to branch lengths so
1093 that 1.23 is printed "1.23" by default, not "1.2300000000".
1095 o The syntax of bind.tree() has been simplified. This function now
1096 accepts trees with no branch lengths, and handles correctly node
1099 o The option `as.numeric' of mrca() has been removed.
1101 o The unused options `format' and `rooted' of read.tree() have
1104 o The unused option `format' of write.tree() has been removed.
1106 o The use of node.depth() has been simplified.
1110 CHANGES IN APE VERSION 1.8-5
1115 o Two new functions read.nexus.data() and write.nexus.data(),
1116 contributed by Johan Nylander, allow to read and write molecular
1117 sequences in NEXUS files.
1119 o The new function reorder.phylo() reorders the internal structure
1120 of a tree of class "phylo". It is used as the generic, e.g.,
1123 o read.tree() and read.nexus() can now read trees with a single
1126 o The new data set `cynipids' supplies a set of protein sequences
1132 o The code of all.equal.phylo() has been completely rewritten
1133 (thanks to Benoît Durand) which fixes several bugs.
1135 o read.tree() and read.nexus() now checks the labels of the tree
1136 to remove or substitute any characters that are illegal in the
1137 Newick format (parentheses, etc.)
1139 o A negative P-value could be returned by mantel.test(): this is
1144 CHANGES IN APE VERSION 1.8-4
1149 o The new function sh.test() computes the Shimodaira-
1152 o The new function collapse.singles() removes the nodes with a
1153 single descendant from a tree.
1155 o plot.phylo() has a new argument `tip.color' to specify the
1156 colours of the tips.
1158 o mlphylo() has now an option `quiet' to control the display of
1159 the progress of the analysis (the default is FALSE).
1164 o read.dna() did not read correctly sequences in sequential format
1165 with leading alignment gaps "-": this is fixed.
1167 o ace() returned a list with no class so that the generic
1168 functions (anova, logLik, ...) could not be used directly. This
1169 is fixed as ace() now returns an object of class "ace".
1171 o anova.ace() had a small bug when computing the number of degrees
1172 of freedom: this is fixed.
1174 o mlphylo() did not work when the sequences were in a matrix or
1175 a data frame: this is fixed.
1177 o rtree() did not work correctly when trying to simulate an
1178 unrooted tree with two tips: an error message is now issued.
1183 o The algorithm of rtree() has been changed: it is now about 40,
1184 100, and 130 times faster for 10, 100, and 1000 tips,
1189 CHANGES IN APE VERSION 1.8-3
1194 o There are four new `method' functions to be used with the
1195 results of ace(): logLik(), deviance(), AIC(), and anova().
1197 o The plot method of phymltest has two new arguments: `main' to
1198 change the title, and `col' to control the colour of the
1199 segments showing the AIC values.
1201 o ace() has a new argument `ip' that gives the initial values used
1202 in the ML estimation with discrete characters (see the examples
1203 in ?ace). This function now returns a matrix giving the indices
1204 of the estimated rates when analysing discrete characters.
1206 o nodelabels() and tiplabels() have a new argument `pie' to
1207 represent proportions, with any number of categories, as
1208 piecharts. The use of the option `thermo' has been improved:
1209 there is now no limitation on the number of categories.
1214 o mlphylo() did not work with more than two partitions: this is
1217 o root() failed if the proposed outgroup was already an outgroup
1218 in the tree: this is fixed.
1220 o The `col' argument in nodelabels() and tiplabels() was not
1221 correctly passed when `text' was used: this is fixed.
1223 o Two bugs were fixed in mlphylo(): parameters were not always
1224 correctly output, and the estimation failed in some cases.
1226 o plot.phylo() was stuck when given a tree with a single tip: this
1227 is fixed and a message error is now returned.
1229 o An error was corrected in the help page of gammaStat regarding
1230 the calculation of P-values.
1232 o Using gls() could crash R when the number of species in the tree
1233 and in the variables were different: this is fixed.
1237 CHANGES IN APE VERSION 1.8-2
1242 o The new function mlphylo() fits a phylogenetic tree by maximum
1243 likelihood from DNA sequences. Its companion function DNAmodel()
1244 is used to define the substitution model which may include
1245 partitioning. There are methods for logLik(), deviance(), and
1246 AIC(), and the summary() method has been extended to display in
1247 a friendly way the results of this model fitting. Currently, the
1248 functionality is limited to estimating the substitution and
1249 associated parameters and computing the likelihood.
1251 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1252 tests for single effects in GEE-based comparative method. A
1253 warning message is printed if there is not enough degrees of
1259 o An error message was sometimes issued by plot.multi.tree(),
1260 though with no consequence.
1264 CHANGES IN APE VERSION 1.8-1
1269 o There is a new plot method for lists of trees (objects of class
1270 "multi.tree"): it calls plot.phylo() internally and is
1271 documented on the same help page.
1276 o A bug was fixed in the C code that analyzes bipartitions: this
1277 has impact on several functions like prop.part, prop.clades,
1278 boot.phylo, or consensus.
1280 o root() did not work correctly when the specified outgroup had
1281 more than one element: this is fixed.
1283 o dist.dna() sometimes returned a warning inappropriately: this
1286 o If the distance object given to nj() had no rownames, nj()
1287 returned a tree with no tip labels: it now returns tips labelled
1288 "1", "2", ..., corresponding to the row numbers.
1293 o nj() has been slightly changed so that tips with a zero distance
1294 are first aggregated with zero-lengthed branches; the usual NJ
1295 procedure is then performed on a distance matrix without 0's.
1299 CHANGES IN APE VERSION 1.8
1304 o The new function chronopl() estimates dates using the penalized
1305 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1307 o The new function consensus() calculates the consensus tree of a
1310 o The new function evolve.phylo() simulates the evolution of
1311 continuous characters along a phylogeny under a Brownian model.
1313 o The new plot method for objects of class "ancestral" displays a
1314 tree together with ancestral values, as returned by the above
1317 o The new function as.phylo.formula() returns a phylogeny from a
1318 set of nested taxonomic variables given as a formula.
1320 o The new function read.caic() reads trees in CAIC format.
1322 o The new function tiplabels() allows to add labels to the tips
1323 of a tree using text or plotting symbols in a flexible way.
1325 o The new function unroot() unroots a phylogeny.
1327 o multi2di() has a new option, `random', which specifies whether
1328 to resolve the multichotomies randomly (the default) or not.
1330 o prop.part() now returns an object of class "prop.part" for which
1331 there are print (to display a partition in a more friendly way)
1332 and summary (to extract the numbers) methods.
1334 o plot.phylo() has a new option, `show.tip.label', specifying
1335 whether to print the labels of the tips. The default is TRUE.
1337 o The code of nj() has been replaced by a faster C code: it is now
1338 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1341 o write.nexus() now writes whether a tree is rooted or not.
1346 o Two bugs have been fixed in root(): unrooted trees are now
1347 handled corretly, and node labels are now output normally.
1349 o A bug was fixed in phymltest(): the executable couldn't be found
1352 o Three bug have been fixed in ace(): computing the likelihood of
1353 ancestral states of discrete characters failed, custom models
1354 did not work, and the function failed with a null gradient (a
1355 warning message is now returned; this latter bug was also
1356 present in yule.cov() as well and is now fixed).
1358 o pic() hanged out when missing data were present: a message error
1361 o A small bug was fixed in dist.dna() where the gamma correction
1362 was not always correctly dispatched.
1364 o plot.phylo() plotted correctly the root edge only when the tree
1365 was plotted rightwards: this works now for all directions.
1370 o dist.taxo() has been renamed as weight.taxo().
1372 o dist.phylo() has been replaced by the method cophenetic.phylo().
1374 o Various error and warning messages have been improved.
1378 CHANGES IN APE VERSION 1.7
1381 o The new function ace() estimates ancestral character states for
1382 continuous characters (with ML, GLS, and contrasts methods), and
1383 discrete characters (with ML only) for any number of states.
1385 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1386 of directional evolution for continuous characters. The user
1387 specifies the node(s) of the tree where the character optimum
1390 o The new function is.rooted() tests whether a tree (of class
1393 o The new function rcoal() generates random ultrametric trees with
1394 the possibility to specify the function that generates the
1395 inter-nodes distances.
1397 o The new function mrca() gives for all pairs of tips in a tree
1398 (and optionally nodes too) the most recent common ancestor.
1400 o nodelabels() has a new option `thermo' to plot proportions (up
1401 to three classes) on the nodes of a tree.
1403 o rtree() has been improved: it can now generate rooted or
1404 unrooted trees, and the mathematical function that generates the
1405 branch lengths may be specified by the user. The tip labels may
1406 be given directly in the call to rtree. The limit cases (n = 2,
1407 3) are now handled correctly.
1409 o dist.topo() has a new argument `method' with two choices: "PH85"
1410 for Penny and Henny's method (already available before and now
1411 the default), and "BHV01" for the geometric distance by Billera
1412 et al. (2001, Adv. Appl. Math. 27:733).
1414 o write.tree() has a new option, `digits', which specifies the
1415 number of digits to be printed in the Newick tree. By default
1416 digits = 10. The numbers are now always printed in decimal form
1417 (i.e., 1.0e-1 is now avoided).
1419 o dist.dna() can now compute the raw distances between pairs of
1420 DNA sequences by specifying model = "raw".
1422 o dist.phylo() has a new option `full' to possibly compute the
1423 distances among all tips and nodes of the tree. The default if
1429 o Several bugs were fixed in all.equal.phylo().
1431 o dist.dna() did not handle correctly gaps ("-") in alignments:
1432 they are now considered as missing data.
1434 o rotate() did not work if the tips were not ordered: this is
1437 o mantel.test() returned NA in some special cases: this is fixed
1438 and the function has been improved and is now faster.
1440 o A bug was fixed in diversi.gof() where the calculation of A² was
1443 o cherry() did not work correctly under some OSs (mainly Linux):
1446 o is.binary.tree() has been modified so that it works with both
1447 rooted and unrooted trees.
1449 o The documentation of theta.s() was not correct: this has been
1452 o plot.mst() did not work correctly: this is fixed.
1456 CHANGES IN APE VERSION 1.6
1461 o The new function dist.topo() computes the topological distances
1464 o The new function boot.phylo() performs a bootstrap analysis on
1465 phylogeny estimation.
1467 o The new functions prop.part() and prop.clades() analyse
1468 bipartitions from a series of trees.
1473 o read.GenBank() now uses the EFetch utility of NCBI instead of
1474 the usual Web interface: it is now much faster (e.g., 12 times
1475 faster to retrieve 8 sequences, 37 times for 60 sequences).
1480 o Several bugs were fixed in read.dna().
1482 o Several bugs were fixed in diversi.time().
1484 o is.binary.tree() did not work correctly if the tree has no edge
1485 lengths: this is fixed.
1487 o drop.tip() did not correctly propagated the `node.label' of a
1488 tree: this is fixed.
1492 CHANGES IN APE VERSION 1.5
1497 o Two new functions, as.matching.phylo() and as.phylo.matching(),
1498 convert objects between the classes "phylo" and "matching". The
1499 latter implements the representation of binary trees introduced by
1500 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
1501 as.matching() has been introduced as well.
1503 o Two new functions, multi2di() and di2multi(), allow to resolve
1504 and collapse multichotomies with branches of length zero.
1506 o The new function nuc.div() computes the nucleotide diversity
1507 from a sample a DNA sequences.
1509 o dist.dna() has been completely rewritten with a much faster
1510 (particularly for large data sets) C code. Eight models are
1511 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
1512 option `method' has been renamed `model'). Computation of variance
1513 is available for all models. A gamma-correction is possible for
1514 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
1515 to remove sites with missing data on a pairwise basis. The option
1516 `GCcontent' has been removed.
1518 o read.GenBank() has a new option (species.names) which specifies
1519 whether to return the species names of the organisms in addition
1520 to the accession numbers of the sequences (this is the default
1523 o write.nexus() can now write several trees in the same NEXUS file.
1525 o drop.tip() has a new option `root.edge' that allows to specify the
1526 new root edge if internal branches are trimmed.
1531 o as.phylo.hclust() failed if some labels had parentheses: this
1534 o Several bugs were fixed in all.equal.phylo(). This function now
1535 returns the logical TRUE if the trees are identical but with
1536 different representations (a report was printed previously).
1538 o read.GenBank() did not correctly handle ambiguous base codes:
1544 o birthdeath() now returns an object of class "birthdeath" for
1545 which there is a print method.
1549 CHANGES IN APE VERSION 1.4
1554 o The new function nj() performs phylogeny estimation with the
1555 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
1558 o The new function which.edge() identifies the edges of a tree
1559 that belong to a group specified as a set of tips.
1561 o The new function as.phylo.phylog() converts an object of class
1562 "phylog" (from the package ade4) into an object of class
1565 o The new function axisPhylo() draws axes on the side of a
1568 o The new function howmanytrees() calculates the number of trees
1569 in different cases and giving a number of tips.
1571 o write.tree() has a new option `multi.line' (TRUE by default) to
1572 write a Newick tree on several lines rather than on a single
1575 o The functionalities of zoom() have been extended. Several
1576 subtrees can be visualized at the same time, and they are marked
1577 on the main tree with colors. The context of the subtrees can be
1578 marked with the option `subtree' (see below).
1580 o drop.tip() has a new option `subtree' (FALSE by default) which
1581 specifies whether to output in the tree how many tips have been
1584 o The arguments of add.scale.bar() have been redefined and have
1585 now default values (see ?add.scale.bar for details). This
1586 function now works even if the plotted tree has no edge length.
1588 o plot.phylo() can now plot radial trees, but this does not take
1589 edge lengths into account.
1591 o In plot.phylo() with `type = "phylogram"', if the values of
1592 `edge.color' and `edge.width' are identical for sister-branches,
1593 they are propagated to the vertical line that link them.
1598 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
1599 crashing. This is fixed.
1601 o In plot.phylo(), the options `edge.color' and `edge.width' are
1602 now properly recycled; their default values are now "black" and
1605 o A bug has been fixed in write.nexus().
1610 o The function node.depth.edgelength() has been removed and
1611 replaced by a C code.
1615 CHANGES IN APE VERSION 1.3-1
1620 o The new function nodelabels() allows to add labels to the nodes
1621 of a tree using text or plotting symbols in a flexible way.
1623 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
1624 numeric values specifying the lower and upper limits on the x-
1625 and y-axes. This allows to leave some space on any side of the
1626 tree. If a single value is given, this is taken as the upper
1631 CHANGES IN APE VERSION 1.3
1636 o The new function phymltest() calls the software PHYML and fits
1637 28 models of DNA sequence evolution. There are a print method to
1638 display likelihood and AIC values, a summary method to compute
1639 the hierarchical likelihood ratio tests, and a plot method to
1640 display graphically the AIC values of each model.
1642 o The new function yule.cov() fits the Yule model with covariates,
1643 a model where the speciation rate is affected by several species
1644 traits through a generalized linear model. The parameters are
1645 estimated by maximum likelihood.
1647 o Three new functions, corBrownian(), corGrafen(), and
1648 corMartins(), compute the expected correlation structures among
1649 species given a phylogeny under different models of evolution.
1650 These can be used for GLS comparative phylogenetic methods (see
1651 the examples). There are coef() and corMatrix() methods and an
1652 Initialize.corPhyl() function associated.
1654 o The new function compar.cheverud() implements Cheverud et al.'s
1655 (1985; Evolution 39:1335) phylogenetic comparative method.
1657 o The new function varcomp() estimates variance components; it has
1660 o Two new functions, panel.superpose.correlogram() and
1661 plot.correlogramList(), allow to plot several phylogenetic
1664 o The new function node.leafnumber() computes the number of leaves
1665 of a subtree defined by a particular node.
1667 o The new function node.sons() gets all tags of son nodes from a
1670 o The new function compute.brlen() computes the branch lengths of
1671 a tree according to a specified method.
1673 o plot.phylo() has three new options: "cex" controls the size of
1674 the (tip and node) labels (thus it is no more needed to change
1675 the global graphical parameter), "direction" which allows to
1676 plot the tree rightwards, leftwards, upwards, or downwards, and
1677 "y.lim" which sets the upper limit on the y-axis.
1682 o Some functions which try to match tip labels and names of
1683 additional data (e.g. vector) are likely to fail if there are
1684 typing or syntax errors. If both series of names do not perfectly
1685 match, they are ignored and a warning message is now issued.
1686 These functions are bd.ext, compar.gee, pic. Their help pages
1687 have been clarified on this point.
1691 CHANGES IN APE VERSION 1.2-7
1696 o The new function root() reroots a phylogenetic tree with respect
1697 to a specified outgroup.
1699 o The new function rotate() rotates an internal branch of a tree.
1701 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
1702 trees) controls the display of the tip labels in unrooted trees.
1703 This display has been greatly improved: the tip labels are now not
1704 expected to overlap with the tree (particularly if lab4ut =
1705 "axial"). In all cases, combining appropriate values of "lab4ut"
1706 and the font size (via "par(cex = )") should result in readable
1707 unrooted trees. See ?plot.phylo for some examples.
1709 o In drop.tip(), the argument `tip' can now be numeric or character.
1714 o drop.tip() did not work correctly with trees with no branch
1715 lengths: this is fixed.
1717 o A bug in plot.phylo(..., type = "unrooted") made some trees being
1718 plotted with some line crossings: this is now fixed.
1722 CHANGES IN APE VERSION 1.2-6
1727 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
1728 correlogram.phylo, dist.taxo, plot.correlogram) have been added
1729 to implement comparative methods with an autocorrelation approach.
1731 o A new data set describing some life history traits of Carnivores
1737 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
1742 o When plotting a tree with plot.phylo(), the new default of the
1743 option `label.offset' is now 0, so the labels are always visible.
1747 CHANGES IN APE VERSION 1.2-5
1752 o The new function bd.ext() fits a birth-death model with combined
1753 phylogenetic and taxonomic data, and estimates the corresponding
1754 speciation and extinction rates.
1759 o The package gee is no more required by ape but only suggested
1760 since only the function compar.gee() calls gee.
1764 CHANGES IN APE VERSION 1.2-4
1769 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
1770 and lines.popsize) implementing a new approach for inferring the
1771 demographic history from genealogies using a reversible jump
1772 MCMC have been introduced.
1774 o The unit of time in the skyline plot and in the new plots can
1775 now be chosen to be actual years, rather than substitutions.
1779 CHANGES IN APE VERSION 1.2-3
1784 o The new function rtree() generates a random binary tree with or
1785 without branch lengths.
1787 o Two new functions for drawing lineages-through-time (LTT) plots
1788 are provided: ltt.lines() adds a LTT curve to an existing plot,
1789 and mltt.plot() does a multiple LTT plot giving several trees as
1790 arguments (see `?ltt.plot' for details).
1795 o Some taxon names made R crashing when calling as.phylo.hclust():
1798 o dist.dna() returned an error with two identical DNA sequences
1799 (only using the Jukes-Cantor method returned 0): this is fixed.
1804 o The function dist.phylo() has been re-written using a different
1805 algorithm: it is now about four times faster.
1807 o The code of branching.times() has been improved: it is now about
1812 CHANGES IN APE VERSION 1.2-2
1817 o The new function seg.sites() finds the segregating sites in a
1818 sample of DNA sequences.
1823 o A bug introduced in read.tree() and in read.nexus() with version
1826 o A few errors were corrected and a few examples were added in the
1831 CHANGES IN APE VERSION 1.2-1
1836 o plot.phylo() can now draw the edge of the root of a tree if it
1837 has one (see the new option `root.edge', its default is FALSE).
1842 o A bug was fixed in read.nexus(): files with semicolons inside
1843 comment blocks were not read correctly.
1845 o The behaviour of read.tree() and read.nexus() was corrected so
1846 that tree files with badly represented root edges (e.g., with
1847 an extra pair of parentheses, see the help pages for details)
1848 are now correctly represented in the object of class "phylo";
1849 a warning message is now issued.
1853 CHANGES IN APE VERSION 1.2
1858 o plot.phylo() has been completely re-written and offers several
1859 new functionalities. Three types of trees can now be drawn:
1860 phylogram (as previously), cladogram, and unrooted tree; in
1861 all three types the branch lengths can be drawn using the edge
1862 lengths of the phylogeny or not (e.g., if the latter is absent).
1863 The vertical position of the nodes can be adjusted with two
1864 choices (see option `node.pos'). The code has been re-structured,
1865 and two new functions (potentially useful for developpers) are
1866 documented separately: node.depth.edgelength() and node.depth();
1867 see the respective help pages for details.
1869 o The new function zoom() allows to explore very large trees by
1870 focusing on a small portion of it.
1872 o The new function yule() fits by maximum likelihood the Yule model
1873 (birth-only process) to a phylogenetic tree.
1875 o Support for writing DNA sequences in FASTA format has been
1876 introduced in write.dna() (support for reading sequences in
1877 this format was introduced in read.dna() in version 1.1-2).
1878 The function has been completely re-written, fixing some bugs
1879 (see below); the default behaviour is no more to display the
1880 sequences on the standard output. Several options have been
1881 introduced to control the sequence printing in a flexible
1882 way. The help page has been extended.
1884 o A new data set is included: a supertree of bats in NEXUS format.
1889 o In theta.s(), the default of the option `variance' has
1890 been changed to `FALSE' (as was indicated in the help page).
1892 o Several bugs were fixed in the code of all.equal.phylo().
1894 o Several bugs were fixed in write.dna(), particularly this
1895 function did not work with `format = "interleaved"'.
1897 o Various errors were corrected in the help pages.
1902 o The argument names of as.hclust.phylo() have been changed
1903 from "(phy)" to "(x, ...)" to conform to the definition of
1904 the corresponding generic function.
1906 o gamma.stat() has been renamed gammaStat() to avoid confusion
1907 since gamma() is a generic function.
1911 CHANGES IN APE VERSION 1.1-3
1916 o base.freq() previously did not return a value of 0 for
1917 bases absent in the data (e.g., a vector of length 3 was
1918 returned if one base was absent). This is now fixed (a
1919 vector of length 4 is always returned).
1921 o Several bugs were fixed in read.nexus(), including that this
1922 function did not work in this absence of a "TRANSLATE"
1923 command in the NEXUS file, and that the commands were
1928 CHANGES IN APE VERSION 1.1-2
1933 o The Tamura and Nei (1993) model of DNA distance is now implemented
1934 in dist.dna(): five models are now available in this function.
1936 o A new data set is included: a set of 15 sequences of the
1937 cytochrome b mitochondrial gene of the woodmouse (Apodemus
1943 o A bug in read.nexus() was fixed.
1945 o read.dna() previously did not work correctly in most cases.
1946 The function has been completely re-written and its help page
1947 has been considerably extended (see ?read.dna for details).
1948 Underscores (_) in taxon names are no more replaced with
1949 spaces (this behaviour was undocumented).
1951 o A bug was fixed in write.dna().
1955 CHANGES IN APE VERSION 1.1-1
1960 o A bug in read.tree() introduced in APE 1.1 was fixed.
1962 o A bug in compar.gee() resulted in an error when trying to fit
1963 a model with `family = "binomial"'. This is now fixed.
1967 CHANGES IN APE VERSION 1.1
1972 o The Klastorin (1982) method as suggested by Misawa and Tajima
1973 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
1974 on the basis of phylogenetic trees has been implemented (see
1975 the function klastorin()).
1977 o Functions have been added to convert APE's "phylo" objects in
1978 "hclust" cluster objects and vice versa (see the help page of
1979 as.phylo for details).
1981 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
1982 are introduced for the estimation of absolute evolutionary rates
1983 (ratogram) and dated clock-like trees (chronogram) from
1984 phylogenetic trees using the non-parametric rate smoothing approach
1985 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
1987 o A summary method is now provided printing a summary information on a
1988 phylogenetic tree with, for instance, `summary(tree)'.
1990 o The behaviour of read.tree() was changed so that all spaces and
1991 tabulations in tree files are now ignored. Consequently, spaces in tip
1992 labels are no more allowed. Another side effect is that read.nexus()
1993 now does not replace the underscores (_) in tip labels with spaces
1994 (this behaviour was undocumented).
1996 o The function plot.phylo() has a new option (`underscore') which
1997 specifies whether the underscores in tip labels should be written on
1998 the plot as such or replaced with spaces (the default).
2000 o The function birthdeath() now computes 95% confidence intervals of
2001 the estimated parameters using profile likelihood.
2003 o Three new data sets are included: a gene tree estimated from 36
2004 landplant rbcL sequences, a gene tree estimated from 32 opsin
2005 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2010 o A bug was fixed in dist.gene() where nothing was returned.
2012 o A bug in plot.mst() was fixed.
2014 o A bug in vcv.phylo() resulted in false correlations when the
2015 option `cor = TRUE' was used (now fixed).
2019 CHANGES IN APE VERSION 1.0
2024 o Two new functions, read.dna() and write.dna(), read/write in a file
2025 DNA sequences in interleaved or in sequential format.
2027 o Two new functions, read.nexus() and write.nexus(), read/write trees
2030 o The new function bind.tree() allows to bind two trees together,
2031 possibly handling root edges to give internal branches.
2033 o The new function drop.tip() removes the tips in a phylogenetic tree,
2034 and trims (or not) the corresponding internal branches.
2036 o The new function is.ultrametric() tests if a tree is ultrametric.
2038 o The function plot.phylo() has more functionalities such as drawing the
2039 branches with different colours and/or different widths, showing the
2040 node labels, controling the position and font of the labels, rotating
2041 the labels, and controling the space around the plot.
2043 o The function read.tree() can now read trees with no branch length,
2044 such as "(a,b),c);". Consequently, the element `edge.length' in
2045 objects of class "phylo" is now optional.
2047 o The function write.tree() has a new default behaviour: if the default
2048 for the option `file' is used (i.e. file = ""), then a variable of
2049 mode character containing the tree in Newick format is returned which
2050 can thus be assigned (e.g., tree <- write.tree(phy)).
2052 o The function read.tree() has a new argument `text' which allows
2053 to read the tree in a variable of mode character.
2055 o A new data set is included: the phylogenetic relationships among
2056 the orders of birds from Sibley and Ahlquist (1990).
2060 CHANGES IN APE VERSION 0.2-1
2065 o Several bugs were fixed in the help pages.
2069 CHANGES IN APE VERSION 0.2
2074 o The function write.tree() writes phylogenetic trees (objects of class
2075 "phylo") in an ASCII file using the Newick parenthetic format.
2077 o The function birthdeath() fits a birth-death model to branching times
2078 by maximum likelihood, and estimates the corresponding speciation and
2081 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2084 o The function is.binary.tree() tests whether a phylogeny is binary.
2086 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2087 as well as some methods are introduced.
2089 o Several functions, including some generics and methods, for computing
2090 skyline plot estimates (classic and generalized) of effective
2091 population size through time are introduced and replace the function
2092 skyline.plot() in version 0.1.
2094 o Two data sets are now included: the phylogenetic relationships among
2095 the families of birds from Sibley and Ahlquist (1990), and an
2096 estimated clock-like phylogeny of HIV sequences sampled in the
2097 Democratic Republic of Congo.
2100 DEPRECATED & DEFUNCT
2102 o The function skyline.plot() in ape 0.1 has been deprecated and
2103 replaced by more elaborate functions (see above).
2108 o Two important bugs were fixed in plot.phylo(): phylogenies with
2109 multichotomies not at the root or not with only terminal branches,
2110 and phylogenies with a single node (i.e. only terminal branches)
2111 did not plot. These trees should be plotted correctly now.
2113 o Several bugs were fixed in diversi.time() in the computation of
2116 o Various errors were corrected in the help pages.
