54 use continuous time algorithms.
56 o The new function drop.fossil removes the extinct species from a
59 o The new function bd.time fits a user-defined time-dependent
60 birth-death model. It is a generalization of yule.time() taking

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

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

208 o A bug was fixed in compar.ou() and the help page was clarified.
210 o bind.tree() has been rewritten fixing several bugs and making it
213 o plot.phylo(type = "p") sometimes failed to colour correctly the

217 in the correct direction though the tip labels were displayed
223 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
224 the sequences are correctly stored (in a list for c, in a matrix
225 for the two other functions).
229 CHANGES IN APE VERSION 2.5
234 o The new function parafit by Pierre Legendre tests for the
235 coevolution between hosts and parasites. It has a companion

260 Rohlf 1995), and some host-parasite specificity data
261 (lmorigin.ex2, from Legendre & Desdevises 2009).
266 o add.scale.bar() drew the bar outside the plotting region with the
267 default options with unrooted or radial trees.

289 and "corPhyl" so that it is possible to calculate the var-cov matrix
290 for "transformation models". vcv.phylo() can still be used for trees
291 of class "phylo"; its argument 'cor' has been renamed 'corr'.
296 o bind.tree() failed when 'y' had no root edge.
298 o read.nexus() shuffled tip labels when the trees have no branch
299 lengths and there is a TRANSLATE block.
301 o read.nexus() does not try to translate node labels if there is a
302 translation table in the NEXUS file. See ?read.nexus for a
303 clarification on this behaviour.

335 o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
336 the tree: the argument is now ignored.

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

432 o drop.tip() has a new option 'rooted' to force (or not) a tree
433 to be treated as (un)rooted.
438 o dist.gene() failed on most occasions with the default
439 pairwise.deletion = FALSE.

577 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
583 o prop.part() failed with a single tree with the default option
584 'check.labels = TRUE'.
586 o summary.DNAbin() failed to display correctly the summary of
587 sequence lengths with lists of sequences of 10,000 bases or more
588 (because summary.default uses 4 significant digits by default).
590 o read.nexus() failed to read a file with a single tree with line
591 breaks in the Newick string.
593 o del.gaps() returned a list of empty sequences when there were no

611 CHANGES IN APE VERSION 2.2-1
616 o The new function makeLabel() helps to modify labels of trees,
617 lists of trees, or DNA sequences, with several utilities to
618 truncate and/or make them unique, substituting some
619 characters, and so on.
621 o The new function del.gaps() removes insertion gaps ("-") in a

668 graphical exploration of large trees (cophyloplot, subtrees,
669 subtreeplot), and to return the graphical coordinates of tree

697 (thanks to Yan Wong for the fix).
699 o drop.tip() failed with some trees (fixed by Yan Wong).
701 o seg.sites() failed with a list.

754 o The argument 'family' of compar.gee() can now be a function
755 as well as a character string.
757 o read.tree() and read.nexus() now return an unnamed list if
760 o read.nexus() now returns a modified object of class "multiPhylo"
761 when there is a TRANSLATE block in the NEXUS file: the individual
762 trees have no 'tip.label' vector, but the list has a 'TipLabel'
763 attribute. The new methods '$' and '[[' set these elements
764 correctly when extracting trees.
768 CHANGES IN APE VERSION 2.1-1
773 o The new function rmtree generates lists of random trees.
775 o rcoal() now generates a genuine coalescent tree by default

814 as its main argument.
816 o plot.correlogram() and plot.correlogramList() have been
817 improved, and gain several options (see the help page for
818 details). A legend is now plotted by default.
823 o dist.dna() returned some incorrect values with `model = "JC69"'
824 and `pairwise.deletion = TRUE'. This affected only the
825 distances involving sequences with missing values. (Thanks
826 to Bruno Toupance for digging this bug out.)
828 o write.tree() failed with some trees: this is fixed by removing
829 the `multi.line' option (trees are now always printed on a
832 o read.nexus() did not correctly detect trees with multiple root
833 edges (see OTHER CHANGES).
838 o The code of mlphylo() has been almost entirely rewritten, and

885 to ignore, by default, the root edge of the tree if it exists.
890 o which.edge() failed when the index of a single terminal edge was
893 o In diversi.time(), the values returned for model C were
896 o A bug was fixed in yule() that affected the calculation of the
897 likelihood in the presence of ties in the branching times.

907 limited number of labelled topologies could be generated.
911 CHANGES IN APE VERSION 2.0-1
916 o The three new functions bionj, fastme.ols, and fastme.bal
917 perform phylogeny estimation by the BIONJ and fastME methods in
918 OLS and balanced versions. This is a port to R of previous
919 previous programs done by Vincent Lefort.
921 o The new function chronoMPL performs molecular dating with the
922 mean path lengths method of Britton et al. (2002, Mol. Phyl.
925 o The new function rotate, contributed by Christoph Heibl, swaps
926 two clades connected to the same node. It works also with
927 multichotomous nodes.
929 o The new `method' as.matrix.DNAbin() may be used to convert
930 easily DNA sequences stored in a list into a matrix while
931 keeping the names and the class.
936 o chronopl() failed when some branch lengths were equal to zero:
937 an error message is now returned.
939 o di2multi() failed when there was a series of consecutive edges
944 CHANGES IN APE VERSION 1.10-2
949 o plot.phylo() can now plot circular trees: the option is type =
950 "fan" or type = "f" (to avoid the ambiguity with type = "c").
952 o prop.part() has a new option `check.labels = FALSE' which allows
953 to considerably speed-up the calculations of bipartitions. As a
954 consequence, calculations of bootstrap values with boot.phylo()
955 should be much faster.
960 o read.GenBank() did not return correctly the list of species as
961 from ape 1.10: this is fixed in this version
963 o Applying as.phylo() on a tree of class "phylo" failed: the
964 object is now returned unchanged.

996 CHANGES IN APE VERSION 1.10
1001 o Five new `method' functions have been introduced to manipulate
1002 DNA sequences in binary format (see below).
1004 o Three new functions have been introduced to convert between the
1005 new binary and the character formats.
1007 o The new function as.alignment converts DNA sequences stored as
1008 single characters into the class "alignment" used by the package
1011 o read.dna() and read.GenBank() have a new argument `as.character'
1012 controlling whether the sequences are returned in binary format
1018 o root() failed when the tree had node labels: this is fixed.
1020 o plot.phylo() did not correctly set the limits on the y-axis with
1021 the default setting: this is fixed.
1023 o dist.dna() returned a wrong result for the LogDet, paralinear,
1024 and BH87 models with `pairwise.deletion = TRUE'.
1029 o DNA sequences are now internally stored in a binary format. See
1030 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1031 details. Most functions analyzing DNA functions have been
1032 modified accordingly and are now much faster (dist.dna is now
1033 ca. 60 times faster).
1037 CHANGES IN APE VERSION 1.9-4
1042 o A bug was fixed in edgelabels().
1044 o as.phylo.hclust() did not work correctly when the object of
1045 class "hclust" has its labels set to NULL: the returned tree has
1046 now its tip labels set to "1", "2", ...
1048 o consensus could fail if some tip labels are a subset of others
1049 (e.g., "a" and "a_1"): this is now fixed.
1051 o mlphylo() failed in most cases if some branch lengths of the
1052 initial tree were greater than one: an error message is now
1055 o mlphylo() failed in most cases when estimating the proportion of
1056 invariants: this is fixed.
1060 CHANGES IN APE VERSION 1.9-3
1065 o The new function edgelabels adds labels on the edge of the tree
1066 in the same way than nodelabels or tiplabels.
1071 o multi2di() did not handle correctly branch lengths with the
1072 default option `random = TRUE': this is now fixed.
1074 o A bug was fixed in nuc.div() when using pairwise deletions.
1076 o A bug occurred in the analysis of bipartitions with large
1077 numbers of large trees, with consequences on prop.part,
1078 prop.clades, and boot.phylo.
1080 o The calculation of the Billera-Holmes-Vogtmann distance in
1081 dist.topo was wrong: this has been fixed.
1085 CHANGES IN APE VERSION 1.9-2
1090 o The new function ladderize reorganizes the internal structure of
1091 a tree to plot them left- or right-ladderized.
1093 o The new function dist.nodes computes the patristic distances
1094 between all nodes, internal and terminal, of a tree. It replaces
1095 the option `full = TRUE' of cophenetic.phylo (see below).
1100 o A bug was fixed in old2new.phylo().
1102 o Some bugs were fixed in chronopl().
1104 o The edge colours were not correctly displayed by plot.phylo
1105 (thank you to Li-San Wang for the fix).
1107 o cophenetic.phylo() failed with multichotomous trees: this is
1113 o read.dna() now returns the sequences in a matrix if they are
1114 aligned (interleaved or sequential format). Sequences in FASTA
1115 format are still returned in a list.
1117 o The option `full' of cophenetic.phylo() has been removed because
1118 it could not be used from the generic.
1121 DEPRECATED & DEFUNCT
1123 o rotate() has been removed; this function did not work correctly
1128 CHANGES IN APE VERSION 1.9-1
1133 o Trees with a single tip were not read correctly in R as the
1134 element `Nnode' was not set: this is fixed.
1136 o unroot() did not set correctly the number of nodes of the
1137 unrooted tree in most cases.
1139 o read.GenBank() failed when fetching very long sequences,
1140 particularly of the BX-series.
1142 o A bug was introduced in read.tree() with ape 1.9: it has been
1147 CHANGES IN APE VERSION 1.9
1152 o There are two new print `methods' for trees of class "phylo" and
1153 lists of trees of class "multi.tree", so that they are now
1154 displayed in a compact and informative way.
1156 o There are two new functions, old2new.phylo and new2old.phylo,
1157 for converting between the old and new coding of the class
1160 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1161 LogDet ("logdet"), and paralinear ("paralin").
1163 o compute.brlen() has been extended: several methods are now
1164 available to compute branch lengths.
1166 o write.dna() can now handle matrices as well as lists.
1171 o cophenetic.phylo() sometimes returned a wrong result with
1172 multichotomous trees: this is fixed.
1174 o rotate() failed when a single tip was specified: the tree is now
1177 o ace() did not return the correct index matrix with custom
1178 models: this is fixed.
1180 o multi2di() did not work correctly when resolving multichotomies
1181 randomly: the topology was always the same, only the arrangement
1182 of clades was randomized: this is fixed. This function now
1183 accepts trees with no branch lengths.
1185 o The output of diversi.gof() was blurred by useless prints when a
1186 user distribution was specified. This has been corrected, and
1187 the help page of this function has been expanded.
1192 o The internal structure of the class "phylo" has been changed:
1193 see the document "Definition of Formats for Coding Phylogenetic
1194 Trees in R" for the details. In addition, the code of most
1195 functions has been improved.
1197 o Several functions have been improved by replacing some R codes
1198 by C codes: pic, plot.phylo, and reorder.phylo.
1200 o There is now a citation information: see citation("ape") in R.
1202 o write.tree() now does not add extra 0's to branch lengths so
1203 that 1.23 is printed "1.23" by default, not "1.2300000000".
1205 o The syntax of bind.tree() has been simplified. This function now
1206 accepts trees with no branch lengths, and handles correctly node
1209 o The option `as.numeric' of mrca() has been removed.
1211 o The unused options `format' and `rooted' of read.tree() have
1214 o The unused option `format' of write.tree() has been removed.
1216 o The use of node.depth() has been simplified.
1220 CHANGES IN APE VERSION 1.8-5
1225 o Two new functions read.nexus.data() and write.nexus.data(),
1226 contributed by Johan Nylander, allow to read and write molecular
1227 sequences in NEXUS files.
1229 o The new function reorder.phylo() reorders the internal structure
1230 of a tree of class "phylo". It is used as the generic, e.g.,
1233 o read.tree() and read.nexus() can now read trees with a single
1236 o The new data set `cynipids' supplies a set of protein sequences
1242 o The code of all.equal.phylo() has been completely rewritten
1243 (thanks to Benoît Durand) which fixes several bugs.
1245 o read.tree() and read.nexus() now checks the labels of the tree
1246 to remove or substitute any characters that are illegal in the
1247 Newick format (parentheses, etc.)
1249 o A negative P-value could be returned by mantel.test(): this is
1254 CHANGES IN APE VERSION 1.8-4
1259 o The new function sh.test() computes the Shimodaira-
1262 o The new function collapse.singles() removes the nodes with a
1263 single descendant from a tree.
1265 o plot.phylo() has a new argument `tip.color' to specify the
1266 colours of the tips.
1268 o mlphylo() has now an option `quiet' to control the display of
1269 the progress of the analysis (the default is FALSE).
1274 o read.dna() did not read correctly sequences in sequential format
1275 with leading alignment gaps "-": this is fixed.
1277 o ace() returned a list with no class so that the generic
1278 functions (anova, logLik, ...) could not be used directly. This
1279 is fixed as ace() now returns an object of class "ace".
1281 o anova.ace() had a small bug when computing the number of degrees
1282 of freedom: this is fixed.
1284 o mlphylo() did not work when the sequences were in a matrix or
1285 a data frame: this is fixed.
1287 o rtree() did not work correctly when trying to simulate an
1288 unrooted tree with two tips: an error message is now issued.
1293 o The algorithm of rtree() has been changed: it is now about 40,
1294 100, and 130 times faster for 10, 100, and 1000 tips,
1299 CHANGES IN APE VERSION 1.8-3
1304 o There are four new `method' functions to be used with the
1305 results of ace(): logLik(), deviance(), AIC(), and anova().
1307 o The plot method of phymltest has two new arguments: `main' to
1308 change the title, and `col' to control the colour of the
1309 segments showing the AIC values.
1311 o ace() has a new argument `ip' that gives the initial values used
1312 in the ML estimation with discrete characters (see the examples
1313 in ?ace). This function now returns a matrix giving the indices
1314 of the estimated rates when analysing discrete characters.
1316 o nodelabels() and tiplabels() have a new argument `pie' to
1317 represent proportions, with any number of categories, as
1318 piecharts. The use of the option `thermo' has been improved:
1319 there is now no limitation on the number of categories.
1324 o mlphylo() did not work with more than two partitions: this is
1327 o root() failed if the proposed outgroup was already an outgroup
1328 in the tree: this is fixed.
1330 o The `col' argument in nodelabels() and tiplabels() was not
1331 correctly passed when `text' was used: this is fixed.
1333 o Two bugs were fixed in mlphylo(): parameters were not always
1334 correctly output, and the estimation failed in some cases.
1336 o plot.phylo() was stuck when given a tree with a single tip: this
1337 is fixed and a message error is now returned.
1339 o An error was corrected in the help page of gammaStat regarding
1340 the calculation of P-values.
1342 o Using gls() could crash R when the number of species in the tree
1343 and in the variables were different: this is fixed.
1347 CHANGES IN APE VERSION 1.8-2
1352 o The new function mlphylo() fits a phylogenetic tree by maximum
1353 likelihood from DNA sequences. Its companion function DNAmodel()
1354 is used to define the substitution model which may include
1355 partitioning. There are methods for logLik(), deviance(), and
1356 AIC(), and the summary() method has been extended to display in
1357 a friendly way the results of this model fitting. Currently, the
1358 functionality is limited to estimating the substitution and
1359 associated parameters and computing the likelihood.
1361 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1362 tests for single effects in GEE-based comparative method. A
1363 warning message is printed if there is not enough degrees of
1369 o An error message was sometimes issued by plot.multi.tree(),
1370 though with no consequence.
1374 CHANGES IN APE VERSION 1.8-1
1379 o There is a new plot method for lists of trees (objects of class
1380 "multi.tree"): it calls plot.phylo() internally and is
1381 documented on the same help page.
1386 o A bug was fixed in the C code that analyzes bipartitions: this
1387 has impact on several functions like prop.part, prop.clades,
1388 boot.phylo, or consensus.
1390 o root() did not work correctly when the specified outgroup had
1391 more than one element: this is fixed.
1393 o dist.dna() sometimes returned a warning inappropriately: this
1396 o If the distance object given to nj() had no rownames, nj()
1397 returned a tree with no tip labels: it now returns tips labelled
1398 "1", "2", ..., corresponding to the row numbers.
1403 o nj() has been slightly changed so that tips with a zero distance
1404 are first aggregated with zero-lengthed branches; the usual NJ
1405 procedure is then performed on a distance matrix without 0's.
1409 CHANGES IN APE VERSION 1.8
1414 o The new function chronopl() estimates dates using the penalized
1415 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1417 o The new function consensus() calculates the consensus tree of a
1420 o The new function evolve.phylo() simulates the evolution of
1421 continuous characters along a phylogeny under a Brownian model.
1423 o The new plot method for objects of class "ancestral" displays a
1424 tree together with ancestral values, as returned by the above
1427 o The new function as.phylo.formula() returns a phylogeny from a
1428 set of nested taxonomic variables given as a formula.
1430 o The new function read.caic() reads trees in CAIC format.
1432 o The new function tiplabels() allows to add labels to the tips
1433 of a tree using text or plotting symbols in a flexible way.
1435 o The new function unroot() unroots a phylogeny.
1437 o multi2di() has a new option, `random', which specifies whether
1438 to resolve the multichotomies randomly (the default) or not.
1440 o prop.part() now returns an object of class "prop.part" for which
1441 there are print (to display a partition in a more friendly way)
1442 and summary (to extract the numbers) methods.
1444 o plot.phylo() has a new option, `show.tip.label', specifying
1445 whether to print the labels of the tips. The default is TRUE.
1447 o The code of nj() has been replaced by a faster C code: it is now
1448 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1451 o write.nexus() now writes whether a tree is rooted or not.
1456 o Two bugs have been fixed in root(): unrooted trees are now
1457 handled corretly, and node labels are now output normally.
1459 o A bug was fixed in phymltest(): the executable couldn't be found
1462 o Three bug have been fixed in ace(): computing the likelihood of
1463 ancestral states of discrete characters failed, custom models
1464 did not work, and the function failed with a null gradient (a
1465 warning message is now returned; this latter bug was also
1466 present in yule.cov() as well and is now fixed).
1468 o pic() hanged out when missing data were present: a message error
1471 o A small bug was fixed in dist.dna() where the gamma correction
1472 was not always correctly dispatched.
1474 o plot.phylo() plotted correctly the root edge only when the tree
1475 was plotted rightwards: this works now for all directions.
1480 o dist.taxo() has been renamed as weight.taxo().
1482 o dist.phylo() has been replaced by the method cophenetic.phylo().
1484 o Various error and warning messages have been improved.
1488 CHANGES IN APE VERSION 1.7
1491 o The new function ace() estimates ancestral character states for
1492 continuous characters (with ML, GLS, and contrasts methods), and
1493 discrete characters (with ML only) for any number of states.
1495 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1496 of directional evolution for continuous characters. The user
1497 specifies the node(s) of the tree where the character optimum
1500 o The new function is.rooted() tests whether a tree (of class
1503 o The new function rcoal() generates random ultrametric trees with
1504 the possibility to specify the function that generates the
1505 inter-nodes distances.
1507 o The new function mrca() gives for all pairs of tips in a tree
1508 (and optionally nodes too) the most recent common ancestor.
1510 o nodelabels() has a new option `thermo' to plot proportions (up
1511 to three classes) on the nodes of a tree.
1513 o rtree() has been improved: it can now generate rooted or
1514 unrooted trees, and the mathematical function that generates the
1515 branch lengths may be specified by the user. The tip labels may
1516 be given directly in the call to rtree. The limit cases (n = 2,
1517 3) are now handled correctly.
1519 o dist.topo() has a new argument `method' with two choices: "PH85"
1520 for Penny and Henny's method (already available before and now
1521 the default), and "BHV01" for the geometric distance by Billera
1522 et al. (2001, Adv. Appl. Math. 27:733).
1524 o write.tree() has a new option, `digits', which specifies the
1525 number of digits to be printed in the Newick tree. By default
1526 digits = 10. The numbers are now always printed in decimal form
1527 (i.e., 1.0e-1 is now avoided).
1529 o dist.dna() can now compute the raw distances between pairs of
1530 DNA sequences by specifying model = "raw".
1532 o dist.phylo() has a new option `full' to possibly compute the
1533 distances among all tips and nodes of the tree. The default if
1539 o Several bugs were fixed in all.equal.phylo().
1541 o dist.dna() did not handle correctly gaps ("-") in alignments:
1542 they are now considered as missing data.
1544 o rotate() did not work if the tips were not ordered: this is
1547 o mantel.test() returned NA in some special cases: this is fixed
1548 and the function has been improved and is now faster.
1550 o A bug was fixed in diversi.gof() where the calculation of A² was
1553 o cherry() did not work correctly under some OSs (mainly Linux):
1556 o is.binary.tree() has been modified so that it works with both
1557 rooted and unrooted trees.
1559 o The documentation of theta.s() was not correct: this has been
1562 o plot.mst() did not work correctly: this is fixed.
1566 CHANGES IN APE VERSION 1.6
1571 o The new function dist.topo() computes the topological distances
1574 o The new function boot.phylo() performs a bootstrap analysis on
1575 phylogeny estimation.
1577 o The new functions prop.part() and prop.clades() analyse
1578 bipartitions from a series of trees.
1583 o read.GenBank() now uses the EFetch utility of NCBI instead of
1584 the usual Web interface: it is now much faster (e.g., 12 times
1585 faster to retrieve 8 sequences, 37 times for 60 sequences).
1590 o Several bugs were fixed in read.dna().
1592 o Several bugs were fixed in diversi.time().
1594 o is.binary.tree() did not work correctly if the tree has no edge
1595 lengths: this is fixed.
1597 o drop.tip() did not correctly propagated the `node.label' of a
1598 tree: this is fixed.
1602 CHANGES IN APE VERSION 1.5
1607 o Two new functions, as.matching.phylo() and as.phylo.matching(),
1608 convert objects between the classes "phylo" and "matching". The
1609 latter implements the representation of binary trees introduced by
1610 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
1611 as.matching() has been introduced as well.
1613 o Two new functions, multi2di() and di2multi(), allow to resolve
1614 and collapse multichotomies with branches of length zero.
1616 o The new function nuc.div() computes the nucleotide diversity
1617 from a sample a DNA sequences.
1619 o dist.dna() has been completely rewritten with a much faster
1620 (particularly for large data sets) C code. Eight models are
1621 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
1622 option `method' has been renamed `model'). Computation of variance
1623 is available for all models. A gamma-correction is possible for
1624 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
1625 to remove sites with missing data on a pairwise basis. The option
1626 `GCcontent' has been removed.
1628 o read.GenBank() has a new option (species.names) which specifies
1629 whether to return the species names of the organisms in addition
1630 to the accession numbers of the sequences (this is the default
1633 o write.nexus() can now write several trees in the same NEXUS file.
1635 o drop.tip() has a new option `root.edge' that allows to specify the
1636 new root edge if internal branches are trimmed.
1641 o as.phylo.hclust() failed if some labels had parentheses: this
1644 o Several bugs were fixed in all.equal.phylo(). This function now
1645 returns the logical TRUE if the trees are identical but with
1646 different representations (a report was printed previously).
1648 o read.GenBank() did not correctly handle ambiguous base codes:
1654 o birthdeath() now returns an object of class "birthdeath" for
1655 which there is a print method.
1659 CHANGES IN APE VERSION 1.4
1664 o The new function nj() performs phylogeny estimation with the
1665 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
1668 o The new function which.edge() identifies the edges of a tree
1669 that belong to a group specified as a set of tips.
1671 o The new function as.phylo.phylog() converts an object of class
1672 "phylog" (from the package ade4) into an object of class
1675 o The new function axisPhylo() draws axes on the side of a
1678 o The new function howmanytrees() calculates the number of trees
1679 in different cases and giving a number of tips.
1681 o write.tree() has a new option `multi.line' (TRUE by default) to
1682 write a Newick tree on several lines rather than on a single
1685 o The functionalities of zoom() have been extended. Several
1686 subtrees can be visualized at the same time, and they are marked
1687 on the main tree with colors. The context of the subtrees can be
1688 marked with the option `subtree' (see below).
1690 o drop.tip() has a new option `subtree' (FALSE by default) which
1691 specifies whether to output in the tree how many tips have been
1694 o The arguments of add.scale.bar() have been redefined and have
1695 now default values (see ?add.scale.bar for details). This
1696 function now works even if the plotted tree has no edge length.
1698 o plot.phylo() can now plot radial trees, but this does not take
1699 edge lengths into account.
1701 o In plot.phylo() with `type = "phylogram"', if the values of
1702 `edge.color' and `edge.width' are identical for sister-branches,
1703 they are propagated to the vertical line that link them.
1708 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
1709 crashing. This is fixed.
1711 o In plot.phylo(), the options `edge.color' and `edge.width' are
1712 now properly recycled; their default values are now "black" and
1715 o A bug has been fixed in write.nexus().
1720 o The function node.depth.edgelength() has been removed and
1721 replaced by a C code.
1725 CHANGES IN APE VERSION 1.3-1
1730 o The new function nodelabels() allows to add labels to the nodes
1731 of a tree using text or plotting symbols in a flexible way.
1733 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
1734 numeric values specifying the lower and upper limits on the x-
1735 and y-axes. This allows to leave some space on any side of the
1736 tree. If a single value is given, this is taken as the upper
1741 CHANGES IN APE VERSION 1.3
1746 o The new function phymltest() calls the software PHYML and fits
1747 28 models of DNA sequence evolution. There are a print method to
1748 display likelihood and AIC values, a summary method to compute
1749 the hierarchical likelihood ratio tests, and a plot method to
1750 display graphically the AIC values of each model.
1752 o The new function yule.cov() fits the Yule model with covariates,
1753 a model where the speciation rate is affected by several species
1754 traits through a generalized linear model. The parameters are
1755 estimated by maximum likelihood.
1757 o Three new functions, corBrownian(), corGrafen(), and
1758 corMartins(), compute the expected correlation structures among
1759 species given a phylogeny under different models of evolution.
1760 These can be used for GLS comparative phylogenetic methods (see
1761 the examples). There are coef() and corMatrix() methods and an
1762 Initialize.corPhyl() function associated.
1764 o The new function compar.cheverud() implements Cheverud et al.'s
1765 (1985; Evolution 39:1335) phylogenetic comparative method.
1767 o The new function varcomp() estimates variance components; it has
1770 o Two new functions, panel.superpose.correlogram() and
1771 plot.correlogramList(), allow to plot several phylogenetic
1774 o The new function node.leafnumber() computes the number of leaves
1775 of a subtree defined by a particular node.
1777 o The new function node.sons() gets all tags of son nodes from a
1780 o The new function compute.brlen() computes the branch lengths of
1781 a tree according to a specified method.
1783 o plot.phylo() has three new options: "cex" controls the size of
1784 the (tip and node) labels (thus it is no more needed to change
1785 the global graphical parameter), "direction" which allows to
1786 plot the tree rightwards, leftwards, upwards, or downwards, and
1787 "y.lim" which sets the upper limit on the y-axis.
1792 o Some functions which try to match tip labels and names of
1793 additional data (e.g. vector) are likely to fail if there are
1794 typing or syntax errors. If both series of names do not perfectly
1795 match, they are ignored and a warning message is now issued.
1796 These functions are bd.ext, compar.gee, pic. Their help pages
1797 have been clarified on this point.

1806 o The new function root() reroots a phylogenetic tree with respect
1807 to a specified outgroup.
1809 o The new function rotate() rotates an internal branch of a tree.
1811 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
1812 trees) controls the display of the tip labels in unrooted trees.
1813 This display has been greatly improved: the tip labels are now not
1814 expected to overlap with the tree (particularly if lab4ut =
1815 "axial"). In all cases, combining appropriate values of "lab4ut"
1816 and the font size (via "par(cex = )") should result in readable
1817 unrooted trees. See ?plot.phylo for some examples.
1819 o In drop.tip(), the argument `tip' can now be numeric or character.
1824 o drop.tip() did not work correctly with trees with no branch
1825 lengths: this is fixed.
1827 o A bug in plot.phylo(..., type = "unrooted") made some trees being
1828 plotted with some line crossings: this is now fixed.
1832 CHANGES IN APE VERSION 1.2-6
1837 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
1838 correlogram.phylo, dist.taxo, plot.correlogram) have been added
1839 to implement comparative methods with an autocorrelation approach.
1841 o A new data set describing some life history traits of Carnivores
1847 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
1852 o When plotting a tree with plot.phylo(), the new default of the
1853 option `label.offset' is now 0, so the labels are always visible.
1857 CHANGES IN APE VERSION 1.2-5
1862 o The new function bd.ext() fits a birth-death model with combined
1863 phylogenetic and taxonomic data, and estimates the corresponding
1864 speciation and extinction rates.
1869 o The package gee is no more required by ape but only suggested
1870 since only the function compar.gee() calls gee.
1874 CHANGES IN APE VERSION 1.2-4
1879 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
1880 and lines.popsize) implementing a new approach for inferring the
1881 demographic history from genealogies using a reversible jump
1882 MCMC have been introduced.
1884 o The unit of time in the skyline plot and in the new plots can
1885 now be chosen to be actual years, rather than substitutions.
1889 CHANGES IN APE VERSION 1.2-3
1894 o The new function rtree() generates a random binary tree with or
1895 without branch lengths.
1897 o Two new functions for drawing lineages-through-time (LTT) plots
1898 are provided: ltt.lines() adds a LTT curve to an existing plot,
1899 and mltt.plot() does a multiple LTT plot giving several trees as
1900 arguments (see `?ltt.plot' for details).
1905 o Some taxon names made R crashing when calling as.phylo.hclust():
1908 o dist.dna() returned an error with two identical DNA sequences
1909 (only using the Jukes-Cantor method returned 0): this is fixed.
1914 o The function dist.phylo() has been re-written using a different
1915 algorithm: it is now about four times faster.
1917 o The code of branching.times() has been improved: it is now about
1922 CHANGES IN APE VERSION 1.2-2
1927 o The new function seg.sites() finds the segregating sites in a
1928 sample of DNA sequences.
1933 o A bug introduced in read.tree() and in read.nexus() with version
1936 o A few errors were corrected and a few examples were added in the
1941 CHANGES IN APE VERSION 1.2-1
1946 o plot.phylo() can now draw the edge of the root of a tree if it
1947 has one (see the new option `root.edge', its default is FALSE).
1952 o A bug was fixed in read.nexus(): files with semicolons inside
1953 comment blocks were not read correctly.
1955 o The behaviour of read.tree() and read.nexus() was corrected so
1956 that tree files with badly represented root edges (e.g., with
1957 an extra pair of parentheses, see the help pages for details)
1958 are now correctly represented in the object of class "phylo";
1959 a warning message is now issued.
1963 CHANGES IN APE VERSION 1.2
1968 o plot.phylo() has been completely re-written and offers several
1969 new functionalities. Three types of trees can now be drawn:
1970 phylogram (as previously), cladogram, and unrooted tree; in
1971 all three types the branch lengths can be drawn using the edge
1972 lengths of the phylogeny or not (e.g., if the latter is absent).
1973 The vertical position of the nodes can be adjusted with two
1974 choices (see option `node.pos'). The code has been re-structured,
1975 and two new functions (potentially useful for developpers) are
1976 documented separately: node.depth.edgelength() and node.depth();
1977 see the respective help pages for details.
1979 o The new function zoom() allows to explore very large trees by
1980 focusing on a small portion of it.
1982 o The new function yule() fits by maximum likelihood the Yule model
1983 (birth-only process) to a phylogenetic tree.
1985 o Support for writing DNA sequences in FASTA format has been
1986 introduced in write.dna() (support for reading sequences in
1987 this format was introduced in read.dna() in version 1.1-2).
1988 The function has been completely re-written, fixing some bugs
1989 (see below); the default behaviour is no more to display the
1990 sequences on the standard output. Several options have been
1991 introduced to control the sequence printing in a flexible
1992 way. The help page has been extended.
1994 o A new data set is included: a supertree of bats in NEXUS format.
1999 o In theta.s(), the default of the option `variance' has
2000 been changed to `FALSE' (as was indicated in the help page).
2002 o Several bugs were fixed in the code of all.equal.phylo().
2004 o Several bugs were fixed in write.dna(), particularly this
2005 function did not work with `format = "interleaved"'.
2007 o Various errors were corrected in the help pages.
2012 o The argument names of as.hclust.phylo() have been changed
2013 from "(phy)" to "(x, ...)" to conform to the definition of
2014 the corresponding generic function.
2016 o gamma.stat() has been renamed gammaStat() to avoid confusion
2017 since gamma() is a generic function.
2021 CHANGES IN APE VERSION 1.1-3
2026 o base.freq() previously did not return a value of 0 for
2027 bases absent in the data (e.g., a vector of length 3 was
2028 returned if one base was absent). This is now fixed (a
2029 vector of length 4 is always returned).
2031 o Several bugs were fixed in read.nexus(), including that this
2032 function did not work in this absence of a "TRANSLATE"
2033 command in the NEXUS file, and that the commands were
2038 CHANGES IN APE VERSION 1.1-2
2043 o The Tamura and Nei (1993) model of DNA distance is now implemented
2044 in dist.dna(): five models are now available in this function.
2046 o A new data set is included: a set of 15 sequences of the
2047 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2053 o A bug in read.nexus() was fixed.
2055 o read.dna() previously did not work correctly in most cases.
2056 The function has been completely re-written and its help page
2057 has been considerably extended (see ?read.dna for details).
2058 Underscores (_) in taxon names are no more replaced with
2059 spaces (this behaviour was undocumented).
2061 o A bug was fixed in write.dna().
2065 CHANGES IN APE VERSION 1.1-1
2070 o A bug in read.tree() introduced in APE 1.1 was fixed.
2072 o A bug in compar.gee() resulted in an error when trying to fit
2073 a model with `family = "binomial"'. This is now fixed.
2077 CHANGES IN APE VERSION 1.1
2082 o The Klastorin (1982) method as suggested by Misawa and Tajima
2083 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2084 on the basis of phylogenetic trees has been implemented (see
2085 the function klastorin()).
2087 o Functions have been added to convert APE's "phylo" objects in
2088 "hclust" cluster objects and vice versa (see the help page of
2089 as.phylo for details).
2091 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2092 are introduced for the estimation of absolute evolutionary rates
2093 (ratogram) and dated clock-like trees (chronogram) from
2094 phylogenetic trees using the non-parametric rate smoothing approach
2095 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2097 o A summary method is now provided printing a summary information on a
2098 phylogenetic tree with, for instance, `summary(tree)'.
2100 o The behaviour of read.tree() was changed so that all spaces and
2101 tabulations in tree files are now ignored. Consequently, spaces in tip
2102 labels are no more allowed. Another side effect is that read.nexus()
2103 now does not replace the underscores (_) in tip labels with spaces
2104 (this behaviour was undocumented).
2106 o The function plot.phylo() has a new option (`underscore') which
2107 specifies whether the underscores in tip labels should be written on
2108 the plot as such or replaced with spaces (the default).
2110 o The function birthdeath() now computes 95% confidence intervals of
2111 the estimated parameters using profile likelihood.
2113 o Three new data sets are included: a gene tree estimated from 36
2114 landplant rbcL sequences, a gene tree estimated from 32 opsin
2115 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2120 o A bug was fixed in dist.gene() where nothing was returned.
2122 o A bug in plot.mst() was fixed.
2124 o A bug in vcv.phylo() resulted in false correlations when the
2125 option `cor = TRUE' was used (now fixed).
2129 CHANGES IN APE VERSION 1.0
2134 o Two new functions, read.dna() and write.dna(), read/write in a file
2135 DNA sequences in interleaved or in sequential format.
2137 o Two new functions, read.nexus() and write.nexus(), read/write trees
2140 o The new function bind.tree() allows to bind two trees together,
2141 possibly handling root edges to give internal branches.
2143 o The new function drop.tip() removes the tips in a phylogenetic tree,
2144 and trims (or not) the corresponding internal branches.
2146 o The new function is.ultrametric() tests if a tree is ultrametric.
2148 o The function plot.phylo() has more functionalities such as drawing the
2149 branches with different colours and/or different widths, showing the
2150 node labels, controling the position and font of the labels, rotating
2151 the labels, and controling the space around the plot.
2153 o The function read.tree() can now read trees with no branch length,
2154 such as "(a,b),c);". Consequently, the element `edge.length' in
2155 objects of class "phylo" is now optional.
2157 o The function write.tree() has a new default behaviour: if the default
2158 for the option `file' is used (i.e. file = ""), then a variable of
2159 mode character containing the tree in Newick format is returned which
2160 can thus be assigned (e.g., tree <- write.tree(phy)).
2162 o The function read.tree() has a new argument `text' which allows
2163 to read the tree in a variable of mode character.
2165 o A new data set is included: the phylogenetic relationships among
2166 the orders of birds from Sibley and Ahlquist (1990).
2170 CHANGES IN APE VERSION 0.2-1
2175 o Several bugs were fixed in the help pages.
2179 CHANGES IN APE VERSION 0.2
2184 o The function write.tree() writes phylogenetic trees (objects of class
2185 "phylo") in an ASCII file using the Newick parenthetic format.
2187 o The function birthdeath() fits a birth-death model to branching times
2188 by maximum likelihood, and estimates the corresponding speciation and
2191 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2194 o The function is.binary.tree() tests whether a phylogeny is binary.
2196 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2197 as well as some methods are introduced.
2199 o Several functions, including some generics and methods, for computing
2200 skyline plot estimates (classic and generalized) of effective
2201 population size through time are introduced and replace the function
2202 skyline.plot() in version 0.1.
2204 o Two data sets are now included: the phylogenetic relationships among
2205 the families of birds from Sibley and Ahlquist (1990), and an
2206 estimated clock-like phylogeny of HIV sequences sampled in the
2207 Democratic Republic of Congo.
2210 DEPRECATED & DEFUNCT
2212 o The function skyline.plot() in ape 0.1 has been deprecated and
2213 replaced by more elaborate functions (see above).
2218 o Two important bugs were fixed in plot.phylo(): phylogenies with
2219 multichotomies not at the root or not with only terminal branches,
2220 and phylogenies with a single node (i.e. only terminal branches)
2221 did not plot. These trees should be plotted correctly now.
2223 o Several bugs were fixed in diversi.time() in the computation of
2226 o Various errors were corrected in the help pages.
