6 o read.dna() failed to read interleaved files if the first line
7 uses tabulations instead of white spaces.
11 o The files ape-defunct.R and ape-defunct.Rd, which have not been
12 modified for almost two years, have been removed.
14 o The C code of bionj() has been reworked: it is more stable (by
15 avoiding passing character strings), slightly faster (by about
16 20%), and more accurate numerically.
18 o The C code of fastme.*() has been slightly modified and should
19 be more stable by avoiding passing character strings (the
20 results are identical to the previous versions).
22 o The file src/newick.c has been removed.
26 CHANGES IN APE VERSION 3.0-3
31 o birthdeath() now catches errors and warnings much better so that
32 a result is returned in most cases.
37 o Because of problems with character string manipulation in C, the
38 examples in ?bionj and in ?fastme have been disallowed. In the
39 meantime, these functions might be unstable. This will be solved
44 CHANGES IN APE VERSION 3.0-2
49 o The new function alex (alignment explorator) zooms in a DNA
50 alignment and opens the result in a new window.
55 o compute.brtime() did not completely randomized the order of the

59 to Matt Johnson for the fix).
61 o mltt.plot(, backward = FALSE) did not set the x-axis correctly.
63 o A bug was introduced in prop.clades() with ape 3.0. The help page
64 has been clarified relative to the use of the option 'rooted'.
66 o mantel.test() printed a useless warning message.
68 o plot.phylo(, direction = "downward") ignored 'y.lim'.
70 o is.monophyletic() did not work correctly if 'tips' was not stored
73 o prop.part() could make R crash if the first tree had many
76 o njs(), bionjs(), and mvrs() now return an error if 'fs < 1'.
78 o SDM() did not work correctly. The code has also been generally
84 o The DESCRIPTION file has been updated.
86 o The option 'original.data' of write.nexus() has been removed.
88 o The files bionjs.c, mvr.c, mvrs.c, njs.c, triangMtd.c, and

90 the corresponding functions.
92 o dist.gene() now coerces input data frame as matrix resulting in
93 much faster calculations (thanks to a suggestion by Markus
98 CHANGES IN APE VERSION 3.0-1
103 o dist.dna() has two new models: "indel" and "indelblock".
105 o bind.tree() now accepts 'position' > 0 when the trees have no
106 banch length permitting to create a node in 'x' when grafting
107 'y' (see ?bind.tree for details).

128 density probability (i.e., the distribution of the number of
129 species) for the Yule, the constant and the time-dependent
130 birth-beath models, respectively. These probabilities can be
131 conditional on no extinction and/or on a log-scale.
133 o plot.phylo() has a new option 'rotate.tree' to rotate unrooted,
134 fan, or radial trees around the center of the plot.
136 o boot.phylo() and prop.clades() have a new option rooted =
137 FALSE. Note that the behaviour of prop.part() is unchanged.
139 o edgelabels() has a new option 'date' to place labels on edges of
140 chronograms using the time scale (suggestion by Rob Lanfear).
145 o In chronopl(), the code setting the initial dates failed in
146 complicated settings (several dates known within intervals).
147 This has been generally improved and should result in faster
148 and more efficient convergence even in simple settings.
150 o mantel.test() sometimes returned P-values > 1 with the default
153 o extract.clade() sometimes shuffled some tip labels (thanks to
154 Ludovic Mallet and Mahendra Mariadassou for the fix).

176 o The code of vcv.phylo() has been improved and is now 10 or 30
177 times faster for 100 or 1000 tips, respectively. Consequently,
178 fitting models with PGLS will be faster overall.
182 CHANGES IN APE VERSION 2.8
187 o Twelve new functions have been written by Andrei-Alin Popescu:
188 additive, ultrametric, is.compatible, arecompatible, mvr, mvrs,
189 njs, bionjs, SDM, treePop, triangMtd, triangMtd*.

195 convert from the class "prop.part" to the class "bitsplits".
197 o The new function ltt.coplot plots on the same scales a tree and
198 the derived LTT plot.
200 o ltt.plot() has two new options: backward and tol. It can now
201 handle non-ultrametic trees and its internal coding has been
202 improved. The coordinates of the plot can now be computed with
203 the new function ltt.plot.coords.
208 o prop.part() crashed if some trees had some multichotomies.
212 CHANGES IN APE VERSION 2.7-3
217 o The new function compute.brtime computes and sets branching times.
219 o mantel.test() has a new argument 'alternative' which is
220 "two-sided" by default. Previously, this test was one-tailed
221 with no possibility to change.
223 o ace() can now do REML estimation with continuous characters,
224 giving better estimates of the variance of the Brownian motion
230 o Branch lengths were wrongly updated with bind.tree(, where = <tip>,
231 position = 0). (Thanks to Liam Revell for digging this bug out.)
233 o Simulation of OU process with rTraitCont() did not work correctly.
234 This now uses formula from Gillespie (1996) reduced to a BM
235 process when alpha = 0 to avoid division by zero. The option
236 'linear' has been removed.
238 o Cross-validation in chronopl() did not work when 'age.max' was
241 o consensus(, p = 0.5) could return an incorrect tree if some
242 incompatible splits occur in 50% of the trees (especially with
243 small number of trees).
245 o c() with "multiPhylo" did not work correctly (thanks to Klaus
246 Schliep for the fix).
248 o root() failed in some cases with an outgroup made of several tips.
249 The help page has been clarified a bit.

259 a constructor function evonet(), a print() and a plot() methods,
260 and four conversion methods to the classes "phylo", "networx",
261 "network", and "igraph".
263 o The new function rTraitMult does multivariate traits simulation
264 with user-defined models.
266 o plot.phylo() has a new option 'plot = TRUE'. If FALSE, the tree
267 is not plotted but the graphical device is set and the
268 coordinates are saved as usual.
270 o diversity.contrast.test() gains a fourth version of the test with
271 method = "logratio"; the literature citations have been clarified.
273 o add.scale.bar() has two new options, 'lwd' and 'lcol', to modify
274 the aspect of the bar.
276 o boot.phylo() now displays a progress bar by default (can be off
279 o There is a new predict() method for compar.gee().
284 o bionj() made R crash if distances were too large. It now returns
285 an error if at least one distance is greater than 100.
287 o drop.tip() returned a wrong tree if 'tip' was of zero length.
289 o read.nexus.data() failed with URLs.
291 o boot.phylo() returned overestimated support values in the
292 presence of identical or nearly identical sequences.

334 left-) clicks (an error was returned previously).
336 o read.nexus() should be robust to commands inserted in the TREES
341 CHANGES IN APE VERSION 2.7
346 o There is a new image() method for "DNAbin" objects: it plots DNA
347 alignments in a flexible and efficient way.
349 o Two new functions as.network.phylo and as.igraph.phylo convert
350 trees of class "phylo" into these respective network classes
351 defined in the packages of the same names.

411 o plot.phylo() did not recycle values of 'font', 'cex' and
412 'tip.color' correctly when type = "fan" or "radial".
414 o plot.phylo() ignored 'label.offset' when type = "radial", "fan", or
415 "unrooted" with lab4ut = "axial" (the placement of tip labels still
416 needs to be improved with lab4ut = "horizontal").
421 o In drop.fossil() the default tol = 0 has been raised to 1e-8.
423 o The help command ?phylo now points to the man page of read.tree()
424 where this class is described. Similarly, ?matching points to the
425 man page of as.matching().

434 o Two new functions, pic.ortho and varCompPhylip, implements the
435 orthonormal contrasts of Felsenstein (2008, Am Nat, 171:713). The

519 control the aspect of thermometers: horiz = TRUE, width = NULL,
522 o compar.gee() has been improved with the new option 'corStruct' as an
523 alternative to 'phy' to specify the correlation structure, and
524 calculation of the QIC (Pan 2001, Biometrics). The display of the
525 results has also been improved.
527 o read.GenBank() has a new option 'gene.names' to return the name of
528 the gene (FALSE by default).

535 o plot.phylo(type = "unrooted") did not force asp = 1 (thanks to Klaus
538 o dist.dna(model = "logdet") used to divide distances by 4. The
539 documentation has been clarified on the formulae used.

561 text to be plotted in different fonts.
563 o There are now replacement operators for [, [[, and $ for the class
564 "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They possibly
565 check that the tip labels are the same in all trees.
567 o Objects of class "multiPhylo" can be built with c(): there are
568 methods for the classes "phylo" and "multiPhylo".
570 o The internal functions .compressTipLabel and .uncompressTipLabel are

637 'interactive' option to make the operation on a plotted tree.
639 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
640 association links; they are recycled like 'col' (which wasn't before).
645 o rTraitDisc() did not use its 'freq' argument correctly (it was
646 multiplied with the rate matrix column-wise instead of row-wise).
648 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
649 with NA values. Nothing is drawn now like with 'text' or 'pch'.

667 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
668 the sequences are correctly stored (in a list for c, in a matrix
669 for the two other functions).
673 CHANGES IN APE VERSION 2.5
678 o The new function parafit by Pierre Legendre tests for the
679 coevolution between hosts and parasites. It has a companion

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

732 o vcv() is a new generic function with methods for the classes "phylo"
733 and "corPhyl" so that it is possible to calculate the var-cov matrix
734 for "transformation models". vcv.phylo() can still be used for trees
735 of class "phylo"; its argument 'cor' has been renamed 'corr'.
740 o bind.tree() failed when 'y' had no root edge.
742 o read.nexus() shuffled tip labels when the trees have no branch
743 lengths and there is a TRANSLATE block.
745 o read.nexus() does not try to translate node labels if there is a
746 translation table in the NEXUS file. See ?read.nexus for a
747 clarification on this behaviour.
749 o plot.multiPhylo() crashed R when plotting a list of trees with
750 compressed tip labels.

788 o Trying to plot a tree with a single tip now returns NULL with a
789 warning (it returned an error previously).
791 o The way lines representing nodes are coloured in phylograms has
792 been modified (as well as their widths and types) following some
793 users' request; this is only for dichotomous nodes.
795 o The argument 'adj' in [node][tip][edge]labels() now works when
796 using 'pie' or 'thermo'.
798 o A more informative message error is now returned by dist.dna() when

853 o extract.clade() sometimes included too many edges.
855 o vcv.phylo() did not work correctly when the tree is in
858 o nj() did not handle correctly distance matrices with many 0's.
859 The code has also been significantly improved: 7, 70, 160 times
860 faster with n = 100, 500, 1000, respectively.
864 CHANGES IN APE VERSION 2.3-1
869 o The new function is.monophyletic tests the monophyly of a group.

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

989 specifying model="N".
994 o chronopl() did not work with CV = TRUE.
996 o read.nexus() did not work correctly in some situations (trees on
997 multiple lines with different numbers of lines and/or with
998 comments inserted within the trees).
1000 o ltt.plot(), ltt.lines(), and mltt.plot() did not count correctly
1001 the number of lineages with non-binary trees.
1006 o ape has now a namespace.
1008 o drop.tip() has been improved: it should be much faster and work
1009 better in some cases (e.g., see the example in ?zoom).
1013 CHANGES IN APE VERSION 2.2-2
1018 o dist.gene() has been substantially improved and gains an option
1019 'pairwise.deletion'.
1021 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
1027 o prop.part() failed with a single tree with the default option
1028 'check.labels = TRUE'.
1030 o summary.DNAbin() failed to display correctly the summary of
1031 sequence lengths with lists of sequences of 10,000 bases or more
1032 (because summary.default uses 4 significant digits by default).
1034 o read.nexus() failed to read a file with a single tree with line
1035 breaks in the Newick string.
1037 o del.gaps() returned a list of empty sequences when there were no
1043 o phymltest() has been updated for PhyML 3.0 and gains an option
1044 'append', whereas the option 'path2exec' has been removed.
1046 o rbind.DNAbin() and cbind.DNAbin() now accept a single matrix
1047 which is returned unchanged (instead of an error).
1049 o The data sets bird.orders and bird.families are now stored as
1050 Newick strings; i.e., the command data(bird.orders) calls
1055 CHANGES IN APE VERSION 2.2-1
1060 o The new function makeLabel() helps to modify labels of trees,
1061 lists of trees, or DNA sequences, with several utilities to
1062 truncate and/or make them unique, substituting some
1063 characters, and so on.
1065 o The new function del.gaps() removes insertion gaps ("-") in a
1066 set of DNA sequences.
1068 o read.dna() can now read Clustal files (*.aln).
1073 o root() failed with 'resolve.root = TRUE' when the root was
1074 already the specified root.
1076 o Several bugs were fixed in mlphylo().
1078 o collapsed.singles() did not propagate the 'Nnode' and
1079 'node.labels' elements (thanks to Elizabeth Purdom for the fix).
1081 o read.nexus() failed to remove correctly the comments within
1084 o read.nexus() failed to read a file with a single tree and no
1085 translation of tip labels.
1087 o read.nexus() failed to place correctly tip labels when reading
1088 a single tree with no edge lengths.
1090 o A bug was fixed in sh.test().
1095 o unique.multiPhylo() is faster thanks to a suggestion by Vladimir
1098 o The option 'check.labels' of consensus() and prop.part() is now
1101 o write.dna() now does not truncate names to 10 characters with
1106 CHANGES IN APE VERSION 2.2
1111 o Four new functions have been written by Damien de Vienne for the
1112 graphical exploration of large trees (cophyloplot, subtrees,
1113 subtreeplot), and to return the graphical coordinates of tree
1116 o The new functions corPagel and corBlomberg implement the Pagel's
1117 "lambda" and Blomberg et al.'s "ACDC" correlation structures.
1119 o chronopl() has been improved and gains several options: see its
1120 help page for details.
1122 o boot.phylo() has now an option 'trees' to possibly return the
1123 bootstraped trees (the default is FALSE).
1125 o prop.part() has been improved and should now be faster in all
1131 o read.dna() failed if "?" occurred in the first 10 sites of the
1134 o The x/y aspect of the plot is now respected when plotting a
1135 circular tree (type = "r" or "f").
1137 o Drawing the tip labels sometimes failed when plotting circular
1140 o zoom() failed when tip labels were used instead of their numbers
1141 (thanks to Yan Wong for the fix).
1143 o drop.tip() failed with some trees (fixed by Yan Wong).
1145 o seg.sites() failed with a list.
1147 o consensus() failed in some cases. The function has been improved
1148 as well and is faster.
1152 CHANGES IN APE VERSION 2.1-3
1157 o A bug in read.nexus() made the Windows R-GUI crash.
1159 o An error was fixed in the computation of ancestral character
1160 states by generalized least squares in ace().
1162 o di2multi() did not modify node labels correctly.
1164 o multi2di() failed if the tree had its attribute "order" set to
1169 CHANGES IN APE VERSION 2.1-2
1174 o There three new methods for the "multiPhylo" class: str, $,
1177 o root() gains the options 'node' and 'resolve.root'
1178 (FALSE by default) as well as its code being improved.
1180 o mltt.plot() has now an option 'log' used in the same way
1181 than in plot.default().
1186 o mltt.plot() failed to display the legend with an unnamed
1189 o nodelabels() with pies now correcly uses the argument
1190 'cex' to draw symbols of different sizes (which has
1191 worked already for thermometers).
1193 o read.nexus() generally failed to read very big files.
1198 o The argument 'family' of compar.gee() can now be a function
1199 as well as a character string.
1201 o read.tree() and read.nexus() now return an unnamed list if
1202 'tree.names = NULL'.
1204 o read.nexus() now returns a modified object of class "multiPhylo"
1205 when there is a TRANSLATE block in the NEXUS file: the individual
1206 trees have no 'tip.label' vector, but the list has a 'TipLabel'
1207 attribute. The new methods '$' and '[[' set these elements
1208 correctly when extracting trees.
1212 CHANGES IN APE VERSION 2.1-1
1217 o The new function rmtree generates lists of random trees.
1219 o rcoal() now generates a genuine coalescent tree by default
1220 (thanks to Vladimir Minin for the code).
1225 o nuc.div() returned an incorrect value with the default
1226 pairwise.deletion = FALSE.
1231 o The internal codes of bionj(), fastme.bal(), and fastme.ols()
1232 have been improved so that they are stabler and faster.
1234 o R packages used by ape are now loaded silently; lattice and gee
1235 are loaded only when needed.
1239 CHANGES IN APE VERSION 2.1
1244 o The new function identify.phylo identifies clades on a plotted
1245 tree using the mouse.
1247 o It is now possible to subset a list of trees (object of class
1248 "multiPhylo") with "[" while keeping its class correct.
1250 o The new function as.DNAbin.alignment converts DNA sequences
1251 stored in the "alignment" format of the package seqinr into
1252 an object of class "DNAbin".
1254 o The new function weight.taxo2 helps to build similarity matrices
1255 given two taxonomic levels (usually called by other functions).
1257 o write.tree() can now take a list of trees (class "multiPhylo")
1258 as its main argument.
1260 o plot.correlogram() and plot.correlogramList() have been
1261 improved, and gain several options (see the help page for
1262 details). A legend is now plotted by default.
1267 o dist.dna() returned some incorrect values with `model = "JC69"'
1268 and `pairwise.deletion = TRUE'. This affected only the
1269 distances involving sequences with missing values. (Thanks
1270 to Bruno Toupance for digging this bug out.)
1272 o write.tree() failed with some trees: this is fixed by removing
1273 the `multi.line' option (trees are now always printed on a
1276 o read.nexus() did not correctly detect trees with multiple root
1277 edges (see OTHER CHANGES).
1282 o The code of mlphylo() has been almost entirely rewritten, and
1283 should be much stabler. The options have been also greatly
1284 simplified (see ?mlphylo and ?DNAmodel for details).
1286 o The internal function nTips has been renamed klastorin_nTips.
1288 o The code of is.ultrametric() contained redundancies and has
1291 o The code of Moran.I() and of correlogram.formula() have been
1294 o read.tree() and read.nexus() now return an error when trying to
1295 read a tree with multiple root edges (see BUG FIXES). The
1296 correction applied in previous version did not work in all
1299 o The class c("multi.tree", "phylo") has been renamed
1305 o There is now a vignette in ape: see vignette("MoranI", "ape").
1308 DEPRECATED & DEFUNCT
1310 o as.matching() and as.phylo.matching() do not support branch
1313 o correlogram.phylo() and discrete.dist() have been removed.
1317 CHANGES IN APE VERSION 2.0-2
1322 o The new function matexpo computes the exponential of a square
1325 o The new function unique.multi.tree removes duplicate trees from
1328 o yule() has a new option `use.root.edge = FALSE' that specifies
1329 to ignore, by default, the root edge of the tree if it exists.
1334 o which.edge() failed when the index of a single terminal edge was
1337 o In diversi.time(), the values returned for model C were
1340 o A bug was fixed in yule() that affected the calculation of the
1341 likelihood in the presence of ties in the branching times.
1343 o There was a bug in the C function mat_expo4x4 affecting the
1344 calculations of the transition probabilities for models HKY and
1347 o A small bug was fixed in as.matrix.DNAbin (thanks to James
1350 o rtree() did not `shuffle' the tip labels by default, so only a
1351 limited number of labelled topologies could be generated.
1355 CHANGES IN APE VERSION 2.0-1
1360 o The three new functions bionj, fastme.ols, and fastme.bal
1361 perform phylogeny estimation by the BIONJ and fastME methods in
1362 OLS and balanced versions. This is a port to R of previous
1363 previous programs done by Vincent Lefort.
1365 o The new function chronoMPL performs molecular dating with the
1366 mean path lengths method of Britton et al. (2002, Mol. Phyl.
1369 o The new function rotate, contributed by Christoph Heibl, swaps
1370 two clades connected to the same node. It works also with
1371 multichotomous nodes.
1373 o The new `method' as.matrix.DNAbin() may be used to convert
1374 easily DNA sequences stored in a list into a matrix while
1375 keeping the names and the class.
1380 o chronopl() failed when some branch lengths were equal to zero:
1381 an error message is now returned.
1383 o di2multi() failed when there was a series of consecutive edges
1388 CHANGES IN APE VERSION 1.10-2
1393 o plot.phylo() can now plot circular trees: the option is type =
1394 "fan" or type = "f" (to avoid the ambiguity with type = "c").
1396 o prop.part() has a new option `check.labels = FALSE' which allows
1397 to considerably speed-up the calculations of bipartitions. As a
1398 consequence, calculations of bootstrap values with boot.phylo()
1399 should be much faster.
1404 o read.GenBank() did not return correctly the list of species as
1405 from ape 1.10: this is fixed in this version
1407 o Applying as.phylo() on a tree of class "phylo" failed: the
1408 object is now returned unchanged.
1412 CHANGES IN APE VERSION 1.10-1
1417 o The three new functions Ntip, Nnode, and Nedge return, for a
1418 given tree, the number of tips, nodes, or edges, respectively.
1423 o read.nexus() did not set correctly the class of the returned
1424 object when reading multiple trees.
1426 o mllt.plot() failed with objects of class c("multi.tree",
1429 o unroot() did not work correctly in most cases.
1431 o reorder.phylo() made R freeze in some occasions.
1433 o Plotting a tree in pruningwise order failed.
1435 o When plotting an unrooted tree, the tip labels where not all
1436 correctly positioned if the option `cex' was used.
1440 CHANGES IN APE VERSION 1.10
1445 o Five new `method' functions have been introduced to manipulate
1446 DNA sequences in binary format (see below).
1448 o Three new functions have been introduced to convert between the
1449 new binary and the character formats.
1451 o The new function as.alignment converts DNA sequences stored as
1452 single characters into the class "alignment" used by the package
1455 o read.dna() and read.GenBank() have a new argument `as.character'
1456 controlling whether the sequences are returned in binary format
1462 o root() failed when the tree had node labels: this is fixed.
1464 o plot.phylo() did not correctly set the limits on the y-axis with
1465 the default setting: this is fixed.
1467 o dist.dna() returned a wrong result for the LogDet, paralinear,
1468 and BH87 models with `pairwise.deletion = TRUE'.
1473 o DNA sequences are now internally stored in a binary format. See
1474 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1475 details. Most functions analyzing DNA functions have been
1476 modified accordingly and are now much faster (dist.dna is now
1477 ca. 60 times faster).
1481 CHANGES IN APE VERSION 1.9-4
1486 o A bug was fixed in edgelabels().
1488 o as.phylo.hclust() did not work correctly when the object of
1489 class "hclust" has its labels set to NULL: the returned tree has
1490 now its tip labels set to "1", "2", ...
1492 o consensus could fail if some tip labels are a subset of others
1493 (e.g., "a" and "a_1"): this is now fixed.
1495 o mlphylo() failed in most cases if some branch lengths of the
1496 initial tree were greater than one: an error message is now
1499 o mlphylo() failed in most cases when estimating the proportion of
1500 invariants: this is fixed.
1504 CHANGES IN APE VERSION 1.9-3
1509 o The new function edgelabels adds labels on the edge of the tree
1510 in the same way than nodelabels or tiplabels.
1515 o multi2di() did not handle correctly branch lengths with the
1516 default option `random = TRUE': this is now fixed.
1518 o A bug was fixed in nuc.div() when using pairwise deletions.
1520 o A bug occurred in the analysis of bipartitions with large
1521 numbers of large trees, with consequences on prop.part,
1522 prop.clades, and boot.phylo.
1524 o The calculation of the Billera-Holmes-Vogtmann distance in
1525 dist.topo was wrong: this has been fixed.
1529 CHANGES IN APE VERSION 1.9-2
1534 o The new function ladderize reorganizes the internal structure of
1535 a tree to plot them left- or right-ladderized.
1537 o The new function dist.nodes computes the patristic distances
1538 between all nodes, internal and terminal, of a tree. It replaces
1539 the option `full = TRUE' of cophenetic.phylo (see below).
1544 o A bug was fixed in old2new.phylo().
1546 o Some bugs were fixed in chronopl().
1548 o The edge colours were not correctly displayed by plot.phylo
1549 (thank you to Li-San Wang for the fix).
1551 o cophenetic.phylo() failed with multichotomous trees: this is
1557 o read.dna() now returns the sequences in a matrix if they are
1558 aligned (interleaved or sequential format). Sequences in FASTA
1559 format are still returned in a list.
1561 o The option `full' of cophenetic.phylo() has been removed because
1562 it could not be used from the generic.
1565 DEPRECATED & DEFUNCT
1567 o rotate() has been removed; this function did not work correctly
1572 CHANGES IN APE VERSION 1.9-1
1577 o Trees with a single tip were not read correctly in R as the
1578 element `Nnode' was not set: this is fixed.
1580 o unroot() did not set correctly the number of nodes of the
1581 unrooted tree in most cases.
1583 o read.GenBank() failed when fetching very long sequences,
1584 particularly of the BX-series.
1586 o A bug was introduced in read.tree() with ape 1.9: it has been
1591 CHANGES IN APE VERSION 1.9
1596 o There are two new print `methods' for trees of class "phylo" and
1597 lists of trees of class "multi.tree", so that they are now
1598 displayed in a compact and informative way.
1600 o There are two new functions, old2new.phylo and new2old.phylo,
1601 for converting between the old and new coding of the class
1604 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1605 LogDet ("logdet"), and paralinear ("paralin").
1607 o compute.brlen() has been extended: several methods are now
1608 available to compute branch lengths.
1610 o write.dna() can now handle matrices as well as lists.
1615 o cophenetic.phylo() sometimes returned a wrong result with
1616 multichotomous trees: this is fixed.
1618 o rotate() failed when a single tip was specified: the tree is now
1621 o ace() did not return the correct index matrix with custom
1622 models: this is fixed.
1624 o multi2di() did not work correctly when resolving multichotomies
1625 randomly: the topology was always the same, only the arrangement
1626 of clades was randomized: this is fixed. This function now
1627 accepts trees with no branch lengths.
1629 o The output of diversi.gof() was blurred by useless prints when a
1630 user distribution was specified. This has been corrected, and
1631 the help page of this function has been expanded.
1636 o The internal structure of the class "phylo" has been changed:
1637 see the document "Definition of Formats for Coding Phylogenetic
1638 Trees in R" for the details. In addition, the code of most
1639 functions has been improved.
1641 o Several functions have been improved by replacing some R codes
1642 by C codes: pic, plot.phylo, and reorder.phylo.
1644 o There is now a citation information: see citation("ape") in R.
1646 o write.tree() now does not add extra 0's to branch lengths so
1647 that 1.23 is printed "1.23" by default, not "1.2300000000".
1649 o The syntax of bind.tree() has been simplified. This function now
1650 accepts trees with no branch lengths, and handles correctly node
1653 o The option `as.numeric' of mrca() has been removed.
1655 o The unused options `format' and `rooted' of read.tree() have
1658 o The unused option `format' of write.tree() has been removed.
1660 o The use of node.depth() has been simplified.
1664 CHANGES IN APE VERSION 1.8-5
1669 o Two new functions read.nexus.data() and write.nexus.data(),
1670 contributed by Johan Nylander, allow to read and write molecular
1671 sequences in NEXUS files.
1673 o The new function reorder.phylo() reorders the internal structure
1674 of a tree of class "phylo". It is used as the generic, e.g.,
1677 o read.tree() and read.nexus() can now read trees with a single
1680 o The new data set `cynipids' supplies a set of protein sequences
1686 o The code of all.equal.phylo() has been completely rewritten
1687 (thanks to Benoît Durand) which fixes several bugs.
1689 o read.tree() and read.nexus() now checks the labels of the tree
1690 to remove or substitute any characters that are illegal in the
1691 Newick format (parentheses, etc.)
1693 o A negative P-value could be returned by mantel.test(): this is
1698 CHANGES IN APE VERSION 1.8-4
1703 o The new function sh.test() computes the Shimodaira-
1706 o The new function collapse.singles() removes the nodes with a
1707 single descendant from a tree.
1709 o plot.phylo() has a new argument `tip.color' to specify the
1710 colours of the tips.
1712 o mlphylo() has now an option `quiet' to control the display of
1713 the progress of the analysis (the default is FALSE).
1718 o read.dna() did not read correctly sequences in sequential format
1719 with leading alignment gaps "-": this is fixed.
1721 o ace() returned a list with no class so that the generic
1722 functions (anova, logLik, ...) could not be used directly. This
1723 is fixed as ace() now returns an object of class "ace".
1725 o anova.ace() had a small bug when computing the number of degrees
1726 of freedom: this is fixed.
1728 o mlphylo() did not work when the sequences were in a matrix or
1729 a data frame: this is fixed.
1731 o rtree() did not work correctly when trying to simulate an
1732 unrooted tree with two tips: an error message is now issued.
1737 o The algorithm of rtree() has been changed: it is now about 40,
1738 100, and 130 times faster for 10, 100, and 1000 tips,
1743 CHANGES IN APE VERSION 1.8-3
1748 o There are four new `method' functions to be used with the
1749 results of ace(): logLik(), deviance(), AIC(), and anova().
1751 o The plot method of phymltest has two new arguments: `main' to
1752 change the title, and `col' to control the colour of the
1753 segments showing the AIC values.
1755 o ace() has a new argument `ip' that gives the initial values used
1756 in the ML estimation with discrete characters (see the examples
1757 in ?ace). This function now returns a matrix giving the indices
1758 of the estimated rates when analysing discrete characters.
1760 o nodelabels() and tiplabels() have a new argument `pie' to
1761 represent proportions, with any number of categories, as
1762 piecharts. The use of the option `thermo' has been improved:
1763 there is now no limitation on the number of categories.
1768 o mlphylo() did not work with more than two partitions: this is
1771 o root() failed if the proposed outgroup was already an outgroup
1772 in the tree: this is fixed.
1774 o The `col' argument in nodelabels() and tiplabels() was not
1775 correctly passed when `text' was used: this is fixed.
1777 o Two bugs were fixed in mlphylo(): parameters were not always
1778 correctly output, and the estimation failed in some cases.
1780 o plot.phylo() was stuck when given a tree with a single tip: this
1781 is fixed and a message error is now returned.
1783 o An error was corrected in the help page of gammaStat regarding
1784 the calculation of P-values.
1786 o Using gls() could crash R when the number of species in the tree
1787 and in the variables were different: this is fixed.
1791 CHANGES IN APE VERSION 1.8-2
1796 o The new function mlphylo() fits a phylogenetic tree by maximum
1797 likelihood from DNA sequences. Its companion function DNAmodel()
1798 is used to define the substitution model which may include
1799 partitioning. There are methods for logLik(), deviance(), and
1800 AIC(), and the summary() method has been extended to display in
1801 a friendly way the results of this model fitting. Currently, the
1802 functionality is limited to estimating the substitution and
1803 associated parameters and computing the likelihood.
1805 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1806 tests for single effects in GEE-based comparative method. A
1807 warning message is printed if there is not enough degrees of
1813 o An error message was sometimes issued by plot.multi.tree(),
1814 though with no consequence.
1818 CHANGES IN APE VERSION 1.8-1
1823 o There is a new plot method for lists of trees (objects of class
1824 "multi.tree"): it calls plot.phylo() internally and is
1825 documented on the same help page.
1830 o A bug was fixed in the C code that analyzes bipartitions: this
1831 has impact on several functions like prop.part, prop.clades,
1832 boot.phylo, or consensus.
1834 o root() did not work correctly when the specified outgroup had
1835 more than one element: this is fixed.
1837 o dist.dna() sometimes returned a warning inappropriately: this
1840 o If the distance object given to nj() had no rownames, nj()
1841 returned a tree with no tip labels: it now returns tips labelled
1842 "1", "2", ..., corresponding to the row numbers.
1847 o nj() has been slightly changed so that tips with a zero distance
1848 are first aggregated with zero-lengthed branches; the usual NJ
1849 procedure is then performed on a distance matrix without 0's.
1853 CHANGES IN APE VERSION 1.8
1858 o The new function chronopl() estimates dates using the penalized
1859 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1861 o The new function consensus() calculates the consensus tree of a
1864 o The new function evolve.phylo() simulates the evolution of
1865 continuous characters along a phylogeny under a Brownian model.
1867 o The new plot method for objects of class "ancestral" displays a
1868 tree together with ancestral values, as returned by the above
1871 o The new function as.phylo.formula() returns a phylogeny from a
1872 set of nested taxonomic variables given as a formula.
1874 o The new function read.caic() reads trees in CAIC format.
1876 o The new function tiplabels() allows to add labels to the tips
1877 of a tree using text or plotting symbols in a flexible way.
1879 o The new function unroot() unroots a phylogeny.
1881 o multi2di() has a new option, `random', which specifies whether
1882 to resolve the multichotomies randomly (the default) or not.
1884 o prop.part() now returns an object of class "prop.part" for which
1885 there are print (to display a partition in a more friendly way)
1886 and summary (to extract the numbers) methods.
1888 o plot.phylo() has a new option, `show.tip.label', specifying
1889 whether to print the labels of the tips. The default is TRUE.
1891 o The code of nj() has been replaced by a faster C code: it is now
1892 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1895 o write.nexus() now writes whether a tree is rooted or not.
1900 o Two bugs have been fixed in root(): unrooted trees are now
1901 handled corretly, and node labels are now output normally.
1903 o A bug was fixed in phymltest(): the executable couldn't be found
1906 o Three bug have been fixed in ace(): computing the likelihood of
1907 ancestral states of discrete characters failed, custom models
1908 did not work, and the function failed with a null gradient (a
1909 warning message is now returned; this latter bug was also
1910 present in yule.cov() as well and is now fixed).
1912 o pic() hanged out when missing data were present: a message error
1915 o A small bug was fixed in dist.dna() where the gamma correction
1916 was not always correctly dispatched.
1918 o plot.phylo() plotted correctly the root edge only when the tree
1919 was plotted rightwards: this works now for all directions.
1924 o dist.taxo() has been renamed as weight.taxo().
1926 o dist.phylo() has been replaced by the method cophenetic.phylo().
1928 o Various error and warning messages have been improved.
1932 CHANGES IN APE VERSION 1.7
1935 o The new function ace() estimates ancestral character states for
1936 continuous characters (with ML, GLS, and contrasts methods), and
1937 discrete characters (with ML only) for any number of states.
1939 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1940 of directional evolution for continuous characters. The user
1941 specifies the node(s) of the tree where the character optimum
1944 o The new function is.rooted() tests whether a tree (of class
1947 o The new function rcoal() generates random ultrametric trees with
1948 the possibility to specify the function that generates the
1949 inter-nodes distances.
1951 o The new function mrca() gives for all pairs of tips in a tree
1952 (and optionally nodes too) the most recent common ancestor.
1954 o nodelabels() has a new option `thermo' to plot proportions (up
1955 to three classes) on the nodes of a tree.
1957 o rtree() has been improved: it can now generate rooted or
1958 unrooted trees, and the mathematical function that generates the
1959 branch lengths may be specified by the user. The tip labels may
1960 be given directly in the call to rtree. The limit cases (n = 2,
1961 3) are now handled correctly.
1963 o dist.topo() has a new argument `method' with two choices: "PH85"
1964 for Penny and Henny's method (already available before and now
1965 the default), and "BHV01" for the geometric distance by Billera
1966 et al. (2001, Adv. Appl. Math. 27:733).
1968 o write.tree() has a new option, `digits', which specifies the
1969 number of digits to be printed in the Newick tree. By default
1970 digits = 10. The numbers are now always printed in decimal form
1971 (i.e., 1.0e-1 is now avoided).
1973 o dist.dna() can now compute the raw distances between pairs of
1974 DNA sequences by specifying model = "raw".
1976 o dist.phylo() has a new option `full' to possibly compute the
1977 distances among all tips and nodes of the tree. The default if
1983 o Several bugs were fixed in all.equal.phylo().
1985 o dist.dna() did not handle correctly gaps ("-") in alignments:
1986 they are now considered as missing data.
1988 o rotate() did not work if the tips were not ordered: this is
1991 o mantel.test() returned NA in some special cases: this is fixed
1992 and the function has been improved and is now faster.
1994 o A bug was fixed in diversi.gof() where the calculation of A² was
1997 o cherry() did not work correctly under some OSs (mainly Linux):
2000 o is.binary.tree() has been modified so that it works with both
2001 rooted and unrooted trees.
2003 o The documentation of theta.s() was not correct: this has been
2006 o plot.mst() did not work correctly: this is fixed.
2010 CHANGES IN APE VERSION 1.6
2015 o The new function dist.topo() computes the topological distances
2018 o The new function boot.phylo() performs a bootstrap analysis on
2019 phylogeny estimation.
2021 o The new functions prop.part() and prop.clades() analyse
2022 bipartitions from a series of trees.
2027 o read.GenBank() now uses the EFetch utility of NCBI instead of
2028 the usual Web interface: it is now much faster (e.g., 12 times
2029 faster to retrieve 8 sequences, 37 times for 60 sequences).
2034 o Several bugs were fixed in read.dna().
2036 o Several bugs were fixed in diversi.time().
2038 o is.binary.tree() did not work correctly if the tree has no edge
2039 lengths: this is fixed.
2041 o drop.tip() did not correctly propagated the `node.label' of a
2042 tree: this is fixed.
2046 CHANGES IN APE VERSION 1.5
2051 o Two new functions, as.matching.phylo() and as.phylo.matching(),
2052 convert objects between the classes "phylo" and "matching". The
2053 latter implements the representation of binary trees introduced by
2054 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
2055 as.matching() has been introduced as well.
2057 o Two new functions, multi2di() and di2multi(), allow to resolve
2058 and collapse multichotomies with branches of length zero.
2060 o The new function nuc.div() computes the nucleotide diversity
2061 from a sample a DNA sequences.
2063 o dist.dna() has been completely rewritten with a much faster
2064 (particularly for large data sets) C code. Eight models are
2065 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
2066 option `method' has been renamed `model'). Computation of variance
2067 is available for all models. A gamma-correction is possible for
2068 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
2069 to remove sites with missing data on a pairwise basis. The option
2070 `GCcontent' has been removed.
2072 o read.GenBank() has a new option (species.names) which specifies
2073 whether to return the species names of the organisms in addition
2074 to the accession numbers of the sequences (this is the default
2077 o write.nexus() can now write several trees in the same NEXUS file.
2079 o drop.tip() has a new option `root.edge' that allows to specify the
2080 new root edge if internal branches are trimmed.
2085 o as.phylo.hclust() failed if some labels had parentheses: this
2088 o Several bugs were fixed in all.equal.phylo(). This function now
2089 returns the logical TRUE if the trees are identical but with
2090 different representations (a report was printed previously).
2092 o read.GenBank() did not correctly handle ambiguous base codes:
2098 o birthdeath() now returns an object of class "birthdeath" for
2099 which there is a print method.
2103 CHANGES IN APE VERSION 1.4
2108 o The new function nj() performs phylogeny estimation with the
2109 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
2112 o The new function which.edge() identifies the edges of a tree
2113 that belong to a group specified as a set of tips.
2115 o The new function as.phylo.phylog() converts an object of class
2116 "phylog" (from the package ade4) into an object of class
2119 o The new function axisPhylo() draws axes on the side of a
2122 o The new function howmanytrees() calculates the number of trees
2123 in different cases and giving a number of tips.
2125 o write.tree() has a new option `multi.line' (TRUE by default) to
2126 write a Newick tree on several lines rather than on a single
2129 o The functionalities of zoom() have been extended. Several
2130 subtrees can be visualized at the same time, and they are marked
2131 on the main tree with colors. The context of the subtrees can be
2132 marked with the option `subtree' (see below).
2134 o drop.tip() has a new option `subtree' (FALSE by default) which
2135 specifies whether to output in the tree how many tips have been
2138 o The arguments of add.scale.bar() have been redefined and have
2139 now default values (see ?add.scale.bar for details). This
2140 function now works even if the plotted tree has no edge length.
2142 o plot.phylo() can now plot radial trees, but this does not take
2143 edge lengths into account.
2145 o In plot.phylo() with `type = "phylogram"', if the values of
2146 `edge.color' and `edge.width' are identical for sister-branches,
2147 they are propagated to the vertical line that link them.
2152 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
2153 crashing. This is fixed.
2155 o In plot.phylo(), the options `edge.color' and `edge.width' are
2156 now properly recycled; their default values are now "black" and
2159 o A bug has been fixed in write.nexus().
2164 o The function node.depth.edgelength() has been removed and
2165 replaced by a C code.
2169 CHANGES IN APE VERSION 1.3-1
2174 o The new function nodelabels() allows to add labels to the nodes
2175 of a tree using text or plotting symbols in a flexible way.
2177 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
2178 numeric values specifying the lower and upper limits on the x-
2179 and y-axes. This allows to leave some space on any side of the
2180 tree. If a single value is given, this is taken as the upper
2185 CHANGES IN APE VERSION 1.3
2190 o The new function phymltest() calls the software PHYML and fits
2191 28 models of DNA sequence evolution. There are a print method to
2192 display likelihood and AIC values, a summary method to compute
2193 the hierarchical likelihood ratio tests, and a plot method to
2194 display graphically the AIC values of each model.
2196 o The new function yule.cov() fits the Yule model with covariates,
2197 a model where the speciation rate is affected by several species
2198 traits through a generalized linear model. The parameters are
2199 estimated by maximum likelihood.
2201 o Three new functions, corBrownian(), corGrafen(), and
2202 corMartins(), compute the expected correlation structures among
2203 species given a phylogeny under different models of evolution.
2204 These can be used for GLS comparative phylogenetic methods (see
2205 the examples). There are coef() and corMatrix() methods and an
2206 Initialize.corPhyl() function associated.
2208 o The new function compar.cheverud() implements Cheverud et al.'s
2209 (1985; Evolution 39:1335) phylogenetic comparative method.
2211 o The new function varcomp() estimates variance components; it has
2214 o Two new functions, panel.superpose.correlogram() and
2215 plot.correlogramList(), allow to plot several phylogenetic
2218 o The new function node.leafnumber() computes the number of leaves
2219 of a subtree defined by a particular node.
2221 o The new function node.sons() gets all tags of son nodes from a
2224 o The new function compute.brlen() computes the branch lengths of
2225 a tree according to a specified method.
2227 o plot.phylo() has three new options: "cex" controls the size of
2228 the (tip and node) labels (thus it is no more needed to change
2229 the global graphical parameter), "direction" which allows to
2230 plot the tree rightwards, leftwards, upwards, or downwards, and
2231 "y.lim" which sets the upper limit on the y-axis.
2236 o Some functions which try to match tip labels and names of
2237 additional data (e.g. vector) are likely to fail if there are
2238 typing or syntax errors. If both series of names do not perfectly
2239 match, they are ignored and a warning message is now issued.
2240 These functions are bd.ext, compar.gee, pic. Their help pages
2241 have been clarified on this point.
2245 CHANGES IN APE VERSION 1.2-7
2250 o The new function root() reroots a phylogenetic tree with respect
2251 to a specified outgroup.
2253 o The new function rotate() rotates an internal branch of a tree.
2255 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
2256 trees) controls the display of the tip labels in unrooted trees.
2257 This display has been greatly improved: the tip labels are now not
2258 expected to overlap with the tree (particularly if lab4ut =
2259 "axial"). In all cases, combining appropriate values of "lab4ut"
2260 and the font size (via "par(cex = )") should result in readable
2261 unrooted trees. See ?plot.phylo for some examples.
2263 o In drop.tip(), the argument `tip' can now be numeric or character.
2268 o drop.tip() did not work correctly with trees with no branch
2269 lengths: this is fixed.
2271 o A bug in plot.phylo(..., type = "unrooted") made some trees being
2272 plotted with some line crossings: this is now fixed.
2276 CHANGES IN APE VERSION 1.2-6
2281 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
2282 correlogram.phylo, dist.taxo, plot.correlogram) have been added
2283 to implement comparative methods with an autocorrelation approach.
2285 o A new data set describing some life history traits of Carnivores
2291 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
2296 o When plotting a tree with plot.phylo(), the new default of the
2297 option `label.offset' is now 0, so the labels are always visible.
2301 CHANGES IN APE VERSION 1.2-5
2306 o The new function bd.ext() fits a birth-death model with combined
2307 phylogenetic and taxonomic data, and estimates the corresponding
2308 speciation and extinction rates.
2313 o The package gee is no more required by ape but only suggested
2314 since only the function compar.gee() calls gee.
2318 CHANGES IN APE VERSION 1.2-4
2323 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
2324 and lines.popsize) implementing a new approach for inferring the
2325 demographic history from genealogies using a reversible jump
2326 MCMC have been introduced.
2328 o The unit of time in the skyline plot and in the new plots can
2329 now be chosen to be actual years, rather than substitutions.
2333 CHANGES IN APE VERSION 1.2-3
2338 o The new function rtree() generates a random binary tree with or
2339 without branch lengths.
2341 o Two new functions for drawing lineages-through-time (LTT) plots
2342 are provided: ltt.lines() adds a LTT curve to an existing plot,
2343 and mltt.plot() does a multiple LTT plot giving several trees as
2344 arguments (see `?ltt.plot' for details).
2349 o Some taxon names made R crashing when calling as.phylo.hclust():
2352 o dist.dna() returned an error with two identical DNA sequences
2353 (only using the Jukes-Cantor method returned 0): this is fixed.
2358 o The function dist.phylo() has been re-written using a different
2359 algorithm: it is now about four times faster.
2361 o The code of branching.times() has been improved: it is now about
2366 CHANGES IN APE VERSION 1.2-2
2371 o The new function seg.sites() finds the segregating sites in a
2372 sample of DNA sequences.
2377 o A bug introduced in read.tree() and in read.nexus() with version
2380 o A few errors were corrected and a few examples were added in the
2385 CHANGES IN APE VERSION 1.2-1
2390 o plot.phylo() can now draw the edge of the root of a tree if it
2391 has one (see the new option `root.edge', its default is FALSE).
2396 o A bug was fixed in read.nexus(): files with semicolons inside
2397 comment blocks were not read correctly.
2399 o The behaviour of read.tree() and read.nexus() was corrected so
2400 that tree files with badly represented root edges (e.g., with
2401 an extra pair of parentheses, see the help pages for details)
2402 are now correctly represented in the object of class "phylo";
2403 a warning message is now issued.
2407 CHANGES IN APE VERSION 1.2
2412 o plot.phylo() has been completely re-written and offers several
2413 new functionalities. Three types of trees can now be drawn:
2414 phylogram (as previously), cladogram, and unrooted tree; in
2415 all three types the branch lengths can be drawn using the edge
2416 lengths of the phylogeny or not (e.g., if the latter is absent).
2417 The vertical position of the nodes can be adjusted with two
2418 choices (see option `node.pos'). The code has been re-structured,
2419 and two new functions (potentially useful for developpers) are
2420 documented separately: node.depth.edgelength() and node.depth();
2421 see the respective help pages for details.
2423 o The new function zoom() allows to explore very large trees by
2424 focusing on a small portion of it.
2426 o The new function yule() fits by maximum likelihood the Yule model
2427 (birth-only process) to a phylogenetic tree.
2429 o Support for writing DNA sequences in FASTA format has been
2430 introduced in write.dna() (support for reading sequences in
2431 this format was introduced in read.dna() in version 1.1-2).
2432 The function has been completely re-written, fixing some bugs
2433 (see below); the default behaviour is no more to display the
2434 sequences on the standard output. Several options have been
2435 introduced to control the sequence printing in a flexible
2436 way. The help page has been extended.
2438 o A new data set is included: a supertree of bats in NEXUS format.
2443 o In theta.s(), the default of the option `variance' has
2444 been changed to `FALSE' (as was indicated in the help page).
2446 o Several bugs were fixed in the code of all.equal.phylo().
2448 o Several bugs were fixed in write.dna(), particularly this
2449 function did not work with `format = "interleaved"'.
2451 o Various errors were corrected in the help pages.
2456 o The argument names of as.hclust.phylo() have been changed
2457 from "(phy)" to "(x, ...)" to conform to the definition of
2458 the corresponding generic function.
2460 o gamma.stat() has been renamed gammaStat() to avoid confusion
2461 since gamma() is a generic function.
2465 CHANGES IN APE VERSION 1.1-3
2470 o base.freq() previously did not return a value of 0 for
2471 bases absent in the data (e.g., a vector of length 3 was
2472 returned if one base was absent). This is now fixed (a
2473 vector of length 4 is always returned).
2475 o Several bugs were fixed in read.nexus(), including that this
2476 function did not work in this absence of a "TRANSLATE"
2477 command in the NEXUS file, and that the commands were
2482 CHANGES IN APE VERSION 1.1-2
2487 o The Tamura and Nei (1993) model of DNA distance is now implemented
2488 in dist.dna(): five models are now available in this function.
2490 o A new data set is included: a set of 15 sequences of the
2491 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2497 o A bug in read.nexus() was fixed.
2499 o read.dna() previously did not work correctly in most cases.
2500 The function has been completely re-written and its help page
2501 has been considerably extended (see ?read.dna for details).
2502 Underscores (_) in taxon names are no more replaced with
2503 spaces (this behaviour was undocumented).
2505 o A bug was fixed in write.dna().
2509 CHANGES IN APE VERSION 1.1-1
2514 o A bug in read.tree() introduced in APE 1.1 was fixed.
2516 o A bug in compar.gee() resulted in an error when trying to fit
2517 a model with `family = "binomial"'. This is now fixed.
2521 CHANGES IN APE VERSION 1.1
2526 o The Klastorin (1982) method as suggested by Misawa and Tajima
2527 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2528 on the basis of phylogenetic trees has been implemented (see
2529 the function klastorin()).
2531 o Functions have been added to convert APE's "phylo" objects in
2532 "hclust" cluster objects and vice versa (see the help page of
2533 as.phylo for details).
2535 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2536 are introduced for the estimation of absolute evolutionary rates
2537 (ratogram) and dated clock-like trees (chronogram) from
2538 phylogenetic trees using the non-parametric rate smoothing approach
2539 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2541 o A summary method is now provided printing a summary information on a
2542 phylogenetic tree with, for instance, `summary(tree)'.
2544 o The behaviour of read.tree() was changed so that all spaces and
2545 tabulations in tree files are now ignored. Consequently, spaces in tip
2546 labels are no more allowed. Another side effect is that read.nexus()
2547 now does not replace the underscores (_) in tip labels with spaces
2548 (this behaviour was undocumented).
2550 o The function plot.phylo() has a new option (`underscore') which
2551 specifies whether the underscores in tip labels should be written on
2552 the plot as such or replaced with spaces (the default).
2554 o The function birthdeath() now computes 95% confidence intervals of
2555 the estimated parameters using profile likelihood.
2557 o Three new data sets are included: a gene tree estimated from 36
2558 landplant rbcL sequences, a gene tree estimated from 32 opsin
2559 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2564 o A bug was fixed in dist.gene() where nothing was returned.
2566 o A bug in plot.mst() was fixed.
2568 o A bug in vcv.phylo() resulted in false correlations when the
2569 option `cor = TRUE' was used (now fixed).
2573 CHANGES IN APE VERSION 1.0
2578 o Two new functions, read.dna() and write.dna(), read/write in a file
2579 DNA sequences in interleaved or in sequential format.
2581 o Two new functions, read.nexus() and write.nexus(), read/write trees
2584 o The new function bind.tree() allows to bind two trees together,
2585 possibly handling root edges to give internal branches.
2587 o The new function drop.tip() removes the tips in a phylogenetic tree,
2588 and trims (or not) the corresponding internal branches.
2590 o The new function is.ultrametric() tests if a tree is ultrametric.
2592 o The function plot.phylo() has more functionalities such as drawing the
2593 branches with different colours and/or different widths, showing the
2594 node labels, controling the position and font of the labels, rotating
2595 the labels, and controling the space around the plot.
2597 o The function read.tree() can now read trees with no branch length,
2598 such as "(a,b),c);". Consequently, the element `edge.length' in
2599 objects of class "phylo" is now optional.
2601 o The function write.tree() has a new default behaviour: if the default
2602 for the option `file' is used (i.e. file = ""), then a variable of
2603 mode character containing the tree in Newick format is returned which
2604 can thus be assigned (e.g., tree <- write.tree(phy)).
2606 o The function read.tree() has a new argument `text' which allows
2607 to read the tree in a variable of mode character.
2609 o A new data set is included: the phylogenetic relationships among
2610 the orders of birds from Sibley and Ahlquist (1990).
2614 CHANGES IN APE VERSION 0.2-1
2619 o Several bugs were fixed in the help pages.
2623 CHANGES IN APE VERSION 0.2
2628 o The function write.tree() writes phylogenetic trees (objects of class
2629 "phylo") in an ASCII file using the Newick parenthetic format.
2631 o The function birthdeath() fits a birth-death model to branching times
2632 by maximum likelihood, and estimates the corresponding speciation and
2635 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2638 o The function is.binary.tree() tests whether a phylogeny is binary.
2640 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2641 as well as some methods are introduced.
2643 o Several functions, including some generics and methods, for computing
2644 skyline plot estimates (classic and generalized) of effective
2645 population size through time are introduced and replace the function
2646 skyline.plot() in version 0.1.
2648 o Two data sets are now included: the phylogenetic relationships among
