1 CHANGES IN APE VERSION 2.6-2
6 o Two new functions, pic.ortho and varCompPhylip, implements the
7 orthonormal contrasts of Felsenstein (2008, Am Nat, 171:713). The

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

75 o compar.gee() has been improved with the new option 'corStruct' as an
76 alternative to 'phy' to specify the correlation structure, and
77 calculation of the QIC (Pan 2001, Biometrics). The display of the

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

190 'interactive' option to make the operation on a plotted tree.
192 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
193 association links; they are recycled like 'col' (which wasn't before).
198 o rTraitDisc() did not use its 'freq' argument correctly (it was
199 multiplied with the rate matrix column-wise instead of row-wise).
201 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
202 with NA values. Nothing is drawn now like with 'text' or 'pch'.
203 The same bug occurred with the 'pie' option.
205 o A bug was fixed in compar.ou() and the help page was clarified.
207 o bind.tree() has been rewritten fixing several bugs and making it
210 o plot.phylo(type = "p") sometimes failed to colour correctly the

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

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

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

324 default is still to return the proportions.
329 o seg.sites() did not handle ambiguous nucleotides correctly: they
332 o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
333 the tree: the argument is now ignored.

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

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

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

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

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

694 (thanks to Yan Wong for the fix).
696 o drop.tip() failed with some trees (fixed by Yan Wong).
698 o seg.sites() failed with a list.

751 o The argument 'family' of compar.gee() can now be a function
752 as well as a character string.
754 o read.tree() and read.nexus() now return an unnamed list if
757 o read.nexus() now returns a modified object of class "multiPhylo"
758 when there is a TRANSLATE block in the NEXUS file: the individual

760 attribute. The new methods '$' and '[[' set these elements
761 correctly when extracting trees.
765 CHANGES IN APE VERSION 2.1-1
770 o The new function rmtree generates lists of random trees.
772 o rcoal() now generates a genuine coalescent tree by default

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

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

897 calculations of the transition probabilities for models HKY and
900 o A small bug was fixed in as.matrix.DNAbin (thanks to James

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

998 o Five new `method' functions have been introduced to manipulate
999 DNA sequences in binary format (see below).
1001 o Three new functions have been introduced to convert between the
1002 new binary and the character formats.
1004 o The new function as.alignment converts DNA sequences stored as
1005 single characters into the class "alignment" used by the package
1008 o read.dna() and read.GenBank() have a new argument `as.character'
1009 controlling whether the sequences are returned in binary format
1015 o root() failed when the tree had node labels: this is fixed.
1017 o plot.phylo() did not correctly set the limits on the y-axis with
1018 the default setting: this is fixed.
1020 o dist.dna() returned a wrong result for the LogDet, paralinear,
1021 and BH87 models with `pairwise.deletion = TRUE'.
1026 o DNA sequences are now internally stored in a binary format. See
1027 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1028 details. Most functions analyzing DNA functions have been
1029 modified accordingly and are now much faster (dist.dna is now
1030 ca. 60 times faster).
1034 CHANGES IN APE VERSION 1.9-4
1039 o A bug was fixed in edgelabels().
1041 o as.phylo.hclust() did not work correctly when the object of
1042 class "hclust" has its labels set to NULL: the returned tree has
1043 now its tip labels set to "1", "2", ...
1045 o consensus could fail if some tip labels are a subset of others
1046 (e.g., "a" and "a_1"): this is now fixed.
1048 o mlphylo() failed in most cases if some branch lengths of the
1049 initial tree were greater than one: an error message is now
1052 o mlphylo() failed in most cases when estimating the proportion of
1053 invariants: this is fixed.
1057 CHANGES IN APE VERSION 1.9-3
1062 o The new function edgelabels adds labels on the edge of the tree
1063 in the same way than nodelabels or tiplabels.
1068 o multi2di() did not handle correctly branch lengths with the
1069 default option `random = TRUE': this is now fixed.
1071 o A bug was fixed in nuc.div() when using pairwise deletions.
1073 o A bug occurred in the analysis of bipartitions with large
1074 numbers of large trees, with consequences on prop.part,
1075 prop.clades, and boot.phylo.
1077 o The calculation of the Billera-Holmes-Vogtmann distance in
1078 dist.topo was wrong: this has been fixed.
1082 CHANGES IN APE VERSION 1.9-2
1087 o The new function ladderize reorganizes the internal structure of
1088 a tree to plot them left- or right-ladderized.
1090 o The new function dist.nodes computes the patristic distances
1091 between all nodes, internal and terminal, of a tree. It replaces
1092 the option `full = TRUE' of cophenetic.phylo (see below).
1097 o A bug was fixed in old2new.phylo().
1099 o Some bugs were fixed in chronopl().
1101 o The edge colours were not correctly displayed by plot.phylo
1102 (thank you to Li-San Wang for the fix).
1104 o cophenetic.phylo() failed with multichotomous trees: this is
1110 o read.dna() now returns the sequences in a matrix if they are
1111 aligned (interleaved or sequential format). Sequences in FASTA
1112 format are still returned in a list.
1114 o The option `full' of cophenetic.phylo() has been removed because
1115 it could not be used from the generic.
1118 DEPRECATED & DEFUNCT
1120 o rotate() has been removed; this function did not work correctly
1125 CHANGES IN APE VERSION 1.9-1
1130 o Trees with a single tip were not read correctly in R as the
1131 element `Nnode' was not set: this is fixed.
1133 o unroot() did not set correctly the number of nodes of the
1134 unrooted tree in most cases.
1136 o read.GenBank() failed when fetching very long sequences,
1137 particularly of the BX-series.
1139 o A bug was introduced in read.tree() with ape 1.9: it has been
1144 CHANGES IN APE VERSION 1.9
1149 o There are two new print `methods' for trees of class "phylo" and
1150 lists of trees of class "multi.tree", so that they are now
1151 displayed in a compact and informative way.
1153 o There are two new functions, old2new.phylo and new2old.phylo,
1154 for converting between the old and new coding of the class
1157 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1158 LogDet ("logdet"), and paralinear ("paralin").
1160 o compute.brlen() has been extended: several methods are now
1161 available to compute branch lengths.
1163 o write.dna() can now handle matrices as well as lists.
1168 o cophenetic.phylo() sometimes returned a wrong result with
1169 multichotomous trees: this is fixed.
1171 o rotate() failed when a single tip was specified: the tree is now
1174 o ace() did not return the correct index matrix with custom
1175 models: this is fixed.
1177 o multi2di() did not work correctly when resolving multichotomies
1178 randomly: the topology was always the same, only the arrangement
1179 of clades was randomized: this is fixed. This function now
1180 accepts trees with no branch lengths.
1182 o The output of diversi.gof() was blurred by useless prints when a
1183 user distribution was specified. This has been corrected, and
1184 the help page of this function has been expanded.
1189 o The internal structure of the class "phylo" has been changed:
1190 see the document "Definition of Formats for Coding Phylogenetic
1191 Trees in R" for the details. In addition, the code of most
1192 functions has been improved.
1194 o Several functions have been improved by replacing some R codes
1195 by C codes: pic, plot.phylo, and reorder.phylo.
1197 o There is now a citation information: see citation("ape") in R.
1199 o write.tree() now does not add extra 0's to branch lengths so
1200 that 1.23 is printed "1.23" by default, not "1.2300000000".
1202 o The syntax of bind.tree() has been simplified. This function now
1203 accepts trees with no branch lengths, and handles correctly node
1206 o The option `as.numeric' of mrca() has been removed.
1208 o The unused options `format' and `rooted' of read.tree() have
1211 o The unused option `format' of write.tree() has been removed.
1213 o The use of node.depth() has been simplified.
1217 CHANGES IN APE VERSION 1.8-5
1222 o Two new functions read.nexus.data() and write.nexus.data(),
1223 contributed by Johan Nylander, allow to read and write molecular
1224 sequences in NEXUS files.
1226 o The new function reorder.phylo() reorders the internal structure
1227 of a tree of class "phylo". It is used as the generic, e.g.,
1230 o read.tree() and read.nexus() can now read trees with a single
1233 o The new data set `cynipids' supplies a set of protein sequences
1239 o The code of all.equal.phylo() has been completely rewritten
1240 (thanks to Benoît Durand) which fixes several bugs.
1242 o read.tree() and read.nexus() now checks the labels of the tree
1243 to remove or substitute any characters that are illegal in the
1244 Newick format (parentheses, etc.)
1246 o A negative P-value could be returned by mantel.test(): this is
1251 CHANGES IN APE VERSION 1.8-4
1256 o The new function sh.test() computes the Shimodaira-
1259 o The new function collapse.singles() removes the nodes with a
1260 single descendant from a tree.
1262 o plot.phylo() has a new argument `tip.color' to specify the
1263 colours of the tips.
1265 o mlphylo() has now an option `quiet' to control the display of
1266 the progress of the analysis (the default is FALSE).
1271 o read.dna() did not read correctly sequences in sequential format
1272 with leading alignment gaps "-": this is fixed.
1274 o ace() returned a list with no class so that the generic
1275 functions (anova, logLik, ...) could not be used directly. This
1276 is fixed as ace() now returns an object of class "ace".
1278 o anova.ace() had a small bug when computing the number of degrees
1279 of freedom: this is fixed.
1281 o mlphylo() did not work when the sequences were in a matrix or
1282 a data frame: this is fixed.
1284 o rtree() did not work correctly when trying to simulate an
1285 unrooted tree with two tips: an error message is now issued.
1290 o The algorithm of rtree() has been changed: it is now about 40,
1291 100, and 130 times faster for 10, 100, and 1000 tips,
1296 CHANGES IN APE VERSION 1.8-3
1301 o There are four new `method' functions to be used with the
1302 results of ace(): logLik(), deviance(), AIC(), and anova().
1304 o The plot method of phymltest has two new arguments: `main' to
1305 change the title, and `col' to control the colour of the
1306 segments showing the AIC values.
1308 o ace() has a new argument `ip' that gives the initial values used
1309 in the ML estimation with discrete characters (see the examples
1310 in ?ace). This function now returns a matrix giving the indices
1311 of the estimated rates when analysing discrete characters.
1313 o nodelabels() and tiplabels() have a new argument `pie' to
1314 represent proportions, with any number of categories, as
1315 piecharts. The use of the option `thermo' has been improved:
1316 there is now no limitation on the number of categories.
1321 o mlphylo() did not work with more than two partitions: this is
1324 o root() failed if the proposed outgroup was already an outgroup
1325 in the tree: this is fixed.
1327 o The `col' argument in nodelabels() and tiplabels() was not
1328 correctly passed when `text' was used: this is fixed.
1330 o Two bugs were fixed in mlphylo(): parameters were not always
1331 correctly output, and the estimation failed in some cases.
1333 o plot.phylo() was stuck when given a tree with a single tip: this
1334 is fixed and a message error is now returned.
1336 o An error was corrected in the help page of gammaStat regarding
1337 the calculation of P-values.
1339 o Using gls() could crash R when the number of species in the tree
1340 and in the variables were different: this is fixed.
1344 CHANGES IN APE VERSION 1.8-2
1349 o The new function mlphylo() fits a phylogenetic tree by maximum
1350 likelihood from DNA sequences. Its companion function DNAmodel()
1351 is used to define the substitution model which may include
1352 partitioning. There are methods for logLik(), deviance(), and
1353 AIC(), and the summary() method has been extended to display in
1354 a friendly way the results of this model fitting. Currently, the
1355 functionality is limited to estimating the substitution and
1356 associated parameters and computing the likelihood.
1358 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1359 tests for single effects in GEE-based comparative method. A
1360 warning message is printed if there is not enough degrees of
1366 o An error message was sometimes issued by plot.multi.tree(),
1367 though with no consequence.
1371 CHANGES IN APE VERSION 1.8-1
1376 o There is a new plot method for lists of trees (objects of class
1377 "multi.tree"): it calls plot.phylo() internally and is
1378 documented on the same help page.
1383 o A bug was fixed in the C code that analyzes bipartitions: this
1384 has impact on several functions like prop.part, prop.clades,
1385 boot.phylo, or consensus.
1387 o root() did not work correctly when the specified outgroup had
1388 more than one element: this is fixed.
1390 o dist.dna() sometimes returned a warning inappropriately: this
1393 o If the distance object given to nj() had no rownames, nj()
1394 returned a tree with no tip labels: it now returns tips labelled
1395 "1", "2", ..., corresponding to the row numbers.
1400 o nj() has been slightly changed so that tips with a zero distance
1401 are first aggregated with zero-lengthed branches; the usual NJ
1402 procedure is then performed on a distance matrix without 0's.
1406 CHANGES IN APE VERSION 1.8
1411 o The new function chronopl() estimates dates using the penalized
1412 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1414 o The new function consensus() calculates the consensus tree of a
1417 o The new function evolve.phylo() simulates the evolution of
1418 continuous characters along a phylogeny under a Brownian model.
1420 o The new plot method for objects of class "ancestral" displays a
1421 tree together with ancestral values, as returned by the above
1424 o The new function as.phylo.formula() returns a phylogeny from a
1425 set of nested taxonomic variables given as a formula.
1427 o The new function read.caic() reads trees in CAIC format.
1429 o The new function tiplabels() allows to add labels to the tips
1430 of a tree using text or plotting symbols in a flexible way.
1432 o The new function unroot() unroots a phylogeny.
1434 o multi2di() has a new option, `random', which specifies whether
1435 to resolve the multichotomies randomly (the default) or not.
1437 o prop.part() now returns an object of class "prop.part" for which
1438 there are print (to display a partition in a more friendly way)
1439 and summary (to extract the numbers) methods.
1441 o plot.phylo() has a new option, `show.tip.label', specifying
1442 whether to print the labels of the tips. The default is TRUE.
1444 o The code of nj() has been replaced by a faster C code: it is now
1445 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1448 o write.nexus() now writes whether a tree is rooted or not.
1453 o Two bugs have been fixed in root(): unrooted trees are now
1454 handled corretly, and node labels are now output normally.
1456 o A bug was fixed in phymltest(): the executable couldn't be found
1459 o Three bug have been fixed in ace(): computing the likelihood of
1460 ancestral states of discrete characters failed, custom models
1461 did not work, and the function failed with a null gradient (a
1462 warning message is now returned; this latter bug was also
1463 present in yule.cov() as well and is now fixed).
1465 o pic() hanged out when missing data were present: a message error
1468 o A small bug was fixed in dist.dna() where the gamma correction
1469 was not always correctly dispatched.
1471 o plot.phylo() plotted correctly the root edge only when the tree
1472 was plotted rightwards: this works now for all directions.
1477 o dist.taxo() has been renamed as weight.taxo().
1479 o dist.phylo() has been replaced by the method cophenetic.phylo().
1481 o Various error and warning messages have been improved.
1485 CHANGES IN APE VERSION 1.7
1488 o The new function ace() estimates ancestral character states for
1489 continuous characters (with ML, GLS, and contrasts methods), and
1490 discrete characters (with ML only) for any number of states.
1492 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1493 of directional evolution for continuous characters. The user
1494 specifies the node(s) of the tree where the character optimum
1497 o The new function is.rooted() tests whether a tree (of class
1500 o The new function rcoal() generates random ultrametric trees with
1501 the possibility to specify the function that generates the
1502 inter-nodes distances.
1504 o The new function mrca() gives for all pairs of tips in a tree
1505 (and optionally nodes too) the most recent common ancestor.
1507 o nodelabels() has a new option `thermo' to plot proportions (up
1508 to three classes) on the nodes of a tree.
1510 o rtree() has been improved: it can now generate rooted or
1511 unrooted trees, and the mathematical function that generates the
1512 branch lengths may be specified by the user. The tip labels may
1513 be given directly in the call to rtree. The limit cases (n = 2,
1514 3) are now handled correctly.
1516 o dist.topo() has a new argument `method' with two choices: "PH85"
1517 for Penny and Henny's method (already available before and now
1518 the default), and "BHV01" for the geometric distance by Billera
1519 et al. (2001, Adv. Appl. Math. 27:733).
1521 o write.tree() has a new option, `digits', which specifies the
1522 number of digits to be printed in the Newick tree. By default
1523 digits = 10. The numbers are now always printed in decimal form
1524 (i.e., 1.0e-1 is now avoided).
1526 o dist.dna() can now compute the raw distances between pairs of
1527 DNA sequences by specifying model = "raw".
1529 o dist.phylo() has a new option `full' to possibly compute the
1530 distances among all tips and nodes of the tree. The default if
1536 o Several bugs were fixed in all.equal.phylo().
1538 o dist.dna() did not handle correctly gaps ("-") in alignments:
1539 they are now considered as missing data.
1541 o rotate() did not work if the tips were not ordered: this is
1544 o mantel.test() returned NA in some special cases: this is fixed
1545 and the function has been improved and is now faster.
1547 o A bug was fixed in diversi.gof() where the calculation of A² was
1550 o cherry() did not work correctly under some OSs (mainly Linux):
1553 o is.binary.tree() has been modified so that it works with both
1554 rooted and unrooted trees.
1556 o The documentation of theta.s() was not correct: this has been
1559 o plot.mst() did not work correctly: this is fixed.
1563 CHANGES IN APE VERSION 1.6
1568 o The new function dist.topo() computes the topological distances
1571 o The new function boot.phylo() performs a bootstrap analysis on
1572 phylogeny estimation.
1574 o The new functions prop.part() and prop.clades() analyse
1575 bipartitions from a series of trees.
1580 o read.GenBank() now uses the EFetch utility of NCBI instead of
1581 the usual Web interface: it is now much faster (e.g., 12 times
1582 faster to retrieve 8 sequences, 37 times for 60 sequences).
1587 o Several bugs were fixed in read.dna().
1589 o Several bugs were fixed in diversi.time().
1591 o is.binary.tree() did not work correctly if the tree has no edge
1592 lengths: this is fixed.
1594 o drop.tip() did not correctly propagated the `node.label' of a
1595 tree: this is fixed.
1599 CHANGES IN APE VERSION 1.5
1604 o Two new functions, as.matching.phylo() and as.phylo.matching(),
1605 convert objects between the classes "phylo" and "matching". The
1606 latter implements the representation of binary trees introduced by
1607 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
1608 as.matching() has been introduced as well.
1610 o Two new functions, multi2di() and di2multi(), allow to resolve
1611 and collapse multichotomies with branches of length zero.
1613 o The new function nuc.div() computes the nucleotide diversity
1614 from a sample a DNA sequences.
1616 o dist.dna() has been completely rewritten with a much faster
1617 (particularly for large data sets) C code. Eight models are
1618 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
1619 option `method' has been renamed `model'). Computation of variance
1620 is available for all models. A gamma-correction is possible for
1621 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
1622 to remove sites with missing data on a pairwise basis. The option
1623 `GCcontent' has been removed.
1625 o read.GenBank() has a new option (species.names) which specifies
1626 whether to return the species names of the organisms in addition
1627 to the accession numbers of the sequences (this is the default
1630 o write.nexus() can now write several trees in the same NEXUS file.
1632 o drop.tip() has a new option `root.edge' that allows to specify the
1633 new root edge if internal branches are trimmed.
1638 o as.phylo.hclust() failed if some labels had parentheses: this
1641 o Several bugs were fixed in all.equal.phylo(). This function now
1642 returns the logical TRUE if the trees are identical but with
1643 different representations (a report was printed previously).
1645 o read.GenBank() did not correctly handle ambiguous base codes:
1651 o birthdeath() now returns an object of class "birthdeath" for
1652 which there is a print method.
1656 CHANGES IN APE VERSION 1.4
1661 o The new function nj() performs phylogeny estimation with the
1662 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
1665 o The new function which.edge() identifies the edges of a tree
1666 that belong to a group specified as a set of tips.
1668 o The new function as.phylo.phylog() converts an object of class
1669 "phylog" (from the package ade4) into an object of class
1672 o The new function axisPhylo() draws axes on the side of a
1675 o The new function howmanytrees() calculates the number of trees
1676 in different cases and giving a number of tips.
1678 o write.tree() has a new option `multi.line' (TRUE by default) to
1679 write a Newick tree on several lines rather than on a single
1682 o The functionalities of zoom() have been extended. Several
1683 subtrees can be visualized at the same time, and they are marked
1684 on the main tree with colors. The context of the subtrees can be
1685 marked with the option `subtree' (see below).
1687 o drop.tip() has a new option `subtree' (FALSE by default) which
1688 specifies whether to output in the tree how many tips have been
1691 o The arguments of add.scale.bar() have been redefined and have
1692 now default values (see ?add.scale.bar for details). This
1693 function now works even if the plotted tree has no edge length.
1695 o plot.phylo() can now plot radial trees, but this does not take
1696 edge lengths into account.
1698 o In plot.phylo() with `type = "phylogram"', if the values of
1699 `edge.color' and `edge.width' are identical for sister-branches,
1700 they are propagated to the vertical line that link them.
1705 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
1706 crashing. This is fixed.
1708 o In plot.phylo(), the options `edge.color' and `edge.width' are
1709 now properly recycled; their default values are now "black" and
1712 o A bug has been fixed in write.nexus().
1717 o The function node.depth.edgelength() has been removed and
1718 replaced by a C code.
1722 CHANGES IN APE VERSION 1.3-1
1727 o The new function nodelabels() allows to add labels to the nodes
1728 of a tree using text or plotting symbols in a flexible way.
1730 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
1731 numeric values specifying the lower and upper limits on the x-
1732 and y-axes. This allows to leave some space on any side of the
1733 tree. If a single value is given, this is taken as the upper
1738 CHANGES IN APE VERSION 1.3
1743 o The new function phymltest() calls the software PHYML and fits
1744 28 models of DNA sequence evolution. There are a print method to
1745 display likelihood and AIC values, a summary method to compute
1746 the hierarchical likelihood ratio tests, and a plot method to
1747 display graphically the AIC values of each model.
1749 o The new function yule.cov() fits the Yule model with covariates,
1750 a model where the speciation rate is affected by several species
1751 traits through a generalized linear model. The parameters are
1752 estimated by maximum likelihood.
1754 o Three new functions, corBrownian(), corGrafen(), and
1755 corMartins(), compute the expected correlation structures among
1756 species given a phylogeny under different models of evolution.
1757 These can be used for GLS comparative phylogenetic methods (see
1758 the examples). There are coef() and corMatrix() methods and an
1759 Initialize.corPhyl() function associated.
1761 o The new function compar.cheverud() implements Cheverud et al.'s
1762 (1985; Evolution 39:1335) phylogenetic comparative method.
1764 o The new function varcomp() estimates variance components; it has
1767 o Two new functions, panel.superpose.correlogram() and
1768 plot.correlogramList(), allow to plot several phylogenetic
1771 o The new function node.leafnumber() computes the number of leaves
1772 of a subtree defined by a particular node.
1774 o The new function node.sons() gets all tags of son nodes from a
1777 o The new function compute.brlen() computes the branch lengths of
1778 a tree according to a specified method.
1780 o plot.phylo() has three new options: "cex" controls the size of
1781 the (tip and node) labels (thus it is no more needed to change
1782 the global graphical parameter), "direction" which allows to
1783 plot the tree rightwards, leftwards, upwards, or downwards, and
1784 "y.lim" which sets the upper limit on the y-axis.
1789 o Some functions which try to match tip labels and names of
1790 additional data (e.g. vector) are likely to fail if there are
1791 typing or syntax errors. If both series of names do not perfectly
1792 match, they are ignored and a warning message is now issued.
1793 These functions are bd.ext, compar.gee, pic. Their help pages
1794 have been clarified on this point.
1798 CHANGES IN APE VERSION 1.2-7
1803 o The new function root() reroots a phylogenetic tree with respect
1804 to a specified outgroup.
1806 o The new function rotate() rotates an internal branch of a tree.
1808 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
1809 trees) controls the display of the tip labels in unrooted trees.
1810 This display has been greatly improved: the tip labels are now not
1811 expected to overlap with the tree (particularly if lab4ut =
1812 "axial"). In all cases, combining appropriate values of "lab4ut"
1813 and the font size (via "par(cex = )") should result in readable
1814 unrooted trees. See ?plot.phylo for some examples.
1816 o In drop.tip(), the argument `tip' can now be numeric or character.
1821 o drop.tip() did not work correctly with trees with no branch
1822 lengths: this is fixed.
1824 o A bug in plot.phylo(..., type = "unrooted") made some trees being
1825 plotted with some line crossings: this is now fixed.
1829 CHANGES IN APE VERSION 1.2-6
1834 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
1835 correlogram.phylo, dist.taxo, plot.correlogram) have been added
1836 to implement comparative methods with an autocorrelation approach.
1838 o A new data set describing some life history traits of Carnivores
1844 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
1849 o When plotting a tree with plot.phylo(), the new default of the
1850 option `label.offset' is now 0, so the labels are always visible.
1854 CHANGES IN APE VERSION 1.2-5
1859 o The new function bd.ext() fits a birth-death model with combined
1860 phylogenetic and taxonomic data, and estimates the corresponding
1861 speciation and extinction rates.
1866 o The package gee is no more required by ape but only suggested
1867 since only the function compar.gee() calls gee.
1871 CHANGES IN APE VERSION 1.2-4
1876 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
1877 and lines.popsize) implementing a new approach for inferring the
1878 demographic history from genealogies using a reversible jump
1879 MCMC have been introduced.
1881 o The unit of time in the skyline plot and in the new plots can
1882 now be chosen to be actual years, rather than substitutions.
1886 CHANGES IN APE VERSION 1.2-3
1891 o The new function rtree() generates a random binary tree with or
1892 without branch lengths.
1894 o Two new functions for drawing lineages-through-time (LTT) plots
1895 are provided: ltt.lines() adds a LTT curve to an existing plot,
1896 and mltt.plot() does a multiple LTT plot giving several trees as
1897 arguments (see `?ltt.plot' for details).
1902 o Some taxon names made R crashing when calling as.phylo.hclust():
1905 o dist.dna() returned an error with two identical DNA sequences
1906 (only using the Jukes-Cantor method returned 0): this is fixed.
1911 o The function dist.phylo() has been re-written using a different
1912 algorithm: it is now about four times faster.
1914 o The code of branching.times() has been improved: it is now about
1919 CHANGES IN APE VERSION 1.2-2
1924 o The new function seg.sites() finds the segregating sites in a
1925 sample of DNA sequences.
1930 o A bug introduced in read.tree() and in read.nexus() with version
1933 o A few errors were corrected and a few examples were added in the
1938 CHANGES IN APE VERSION 1.2-1
1943 o plot.phylo() can now draw the edge of the root of a tree if it
1944 has one (see the new option `root.edge', its default is FALSE).
1949 o A bug was fixed in read.nexus(): files with semicolons inside
1950 comment blocks were not read correctly.
1952 o The behaviour of read.tree() and read.nexus() was corrected so
1953 that tree files with badly represented root edges (e.g., with
1954 an extra pair of parentheses, see the help pages for details)
1955 are now correctly represented in the object of class "phylo";
1956 a warning message is now issued.
1960 CHANGES IN APE VERSION 1.2
1965 o plot.phylo() has been completely re-written and offers several
1966 new functionalities. Three types of trees can now be drawn:
1967 phylogram (as previously), cladogram, and unrooted tree; in
1968 all three types the branch lengths can be drawn using the edge
1969 lengths of the phylogeny or not (e.g., if the latter is absent).
1970 The vertical position of the nodes can be adjusted with two
1971 choices (see option `node.pos'). The code has been re-structured,
1972 and two new functions (potentially useful for developpers) are
1973 documented separately: node.depth.edgelength() and node.depth();
1974 see the respective help pages for details.
1976 o The new function zoom() allows to explore very large trees by
1977 focusing on a small portion of it.
1979 o The new function yule() fits by maximum likelihood the Yule model
1980 (birth-only process) to a phylogenetic tree.
1982 o Support for writing DNA sequences in FASTA format has been
1983 introduced in write.dna() (support for reading sequences in
1984 this format was introduced in read.dna() in version 1.1-2).
1985 The function has been completely re-written, fixing some bugs
1986 (see below); the default behaviour is no more to display the
1987 sequences on the standard output. Several options have been
1988 introduced to control the sequence printing in a flexible
1989 way. The help page has been extended.
1991 o A new data set is included: a supertree of bats in NEXUS format.
1996 o In theta.s(), the default of the option `variance' has
1997 been changed to `FALSE' (as was indicated in the help page).
1999 o Several bugs were fixed in the code of all.equal.phylo().
2001 o Several bugs were fixed in write.dna(), particularly this
2002 function did not work with `format = "interleaved"'.
2004 o Various errors were corrected in the help pages.
2009 o The argument names of as.hclust.phylo() have been changed
2010 from "(phy)" to "(x, ...)" to conform to the definition of
2011 the corresponding generic function.
2013 o gamma.stat() has been renamed gammaStat() to avoid confusion
2014 since gamma() is a generic function.
2018 CHANGES IN APE VERSION 1.1-3
2023 o base.freq() previously did not return a value of 0 for
2024 bases absent in the data (e.g., a vector of length 3 was
2025 returned if one base was absent). This is now fixed (a
2026 vector of length 4 is always returned).
2028 o Several bugs were fixed in read.nexus(), including that this
2029 function did not work in this absence of a "TRANSLATE"
2030 command in the NEXUS file, and that the commands were
2035 CHANGES IN APE VERSION 1.1-2
2040 o The Tamura and Nei (1993) model of DNA distance is now implemented
2041 in dist.dna(): five models are now available in this function.
2043 o A new data set is included: a set of 15 sequences of the
2044 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2050 o A bug in read.nexus() was fixed.
2052 o read.dna() previously did not work correctly in most cases.
2053 The function has been completely re-written and its help page
2054 has been considerably extended (see ?read.dna for details).
2055 Underscores (_) in taxon names are no more replaced with
2056 spaces (this behaviour was undocumented).
2058 o A bug was fixed in write.dna().
2062 CHANGES IN APE VERSION 1.1-1
2067 o A bug in read.tree() introduced in APE 1.1 was fixed.
2069 o A bug in compar.gee() resulted in an error when trying to fit
2070 a model with `family = "binomial"'. This is now fixed.
2074 CHANGES IN APE VERSION 1.1
2079 o The Klastorin (1982) method as suggested by Misawa and Tajima
2080 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2081 on the basis of phylogenetic trees has been implemented (see
2082 the function klastorin()).
2084 o Functions have been added to convert APE's "phylo" objects in
2085 "hclust" cluster objects and vice versa (see the help page of
2086 as.phylo for details).
2088 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2089 are introduced for the estimation of absolute evolutionary rates
2090 (ratogram) and dated clock-like trees (chronogram) from
2091 phylogenetic trees using the non-parametric rate smoothing approach
2092 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2094 o A summary method is now provided printing a summary information on a
2095 phylogenetic tree with, for instance, `summary(tree)'.
2097 o The behaviour of read.tree() was changed so that all spaces and
2098 tabulations in tree files are now ignored. Consequently, spaces in tip
2099 labels are no more allowed. Another side effect is that read.nexus()
2100 now does not replace the underscores (_) in tip labels with spaces
2101 (this behaviour was undocumented).
2103 o The function plot.phylo() has a new option (`underscore') which
2104 specifies whether the underscores in tip labels should be written on
2105 the plot as such or replaced with spaces (the default).
2107 o The function birthdeath() now computes 95% confidence intervals of
2108 the estimated parameters using profile likelihood.
2110 o Three new data sets are included: a gene tree estimated from 36
2111 landplant rbcL sequences, a gene tree estimated from 32 opsin
2112 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2117 o A bug was fixed in dist.gene() where nothing was returned.
2119 o A bug in plot.mst() was fixed.
2121 o A bug in vcv.phylo() resulted in false correlations when the
2122 option `cor = TRUE' was used (now fixed).
2126 CHANGES IN APE VERSION 1.0
2131 o Two new functions, read.dna() and write.dna(), read/write in a file
2132 DNA sequences in interleaved or in sequential format.
2134 o Two new functions, read.nexus() and write.nexus(), read/write trees
2137 o The new function bind.tree() allows to bind two trees together,
2138 possibly handling root edges to give internal branches.
2140 o The new function drop.tip() removes the tips in a phylogenetic tree,
2141 and trims (or not) the corresponding internal branches.
2143 o The new function is.ultrametric() tests if a tree is ultrametric.
2145 o The function plot.phylo() has more functionalities such as drawing the
2146 branches with different colours and/or different widths, showing the
2147 node labels, controling the position and font of the labels, rotating
2148 the labels, and controling the space around the plot.
2150 o The function read.tree() can now read trees with no branch length,
2151 such as "(a,b),c);". Consequently, the element `edge.length' in
2152 objects of class "phylo" is now optional.
2154 o The function write.tree() has a new default behaviour: if the default
2155 for the option `file' is used (i.e. file = ""), then a variable of
2156 mode character containing the tree in Newick format is returned which
2157 can thus be assigned (e.g., tree <- write.tree(phy)).
2159 o The function read.tree() has a new argument `text' which allows
2160 to read the tree in a variable of mode character.
2162 o A new data set is included: the phylogenetic relationships among
2163 the orders of birds from Sibley and Ahlquist (1990).
2167 CHANGES IN APE VERSION 0.2-1
2172 o Several bugs were fixed in the help pages.
2176 CHANGES IN APE VERSION 0.2
2181 o The function write.tree() writes phylogenetic trees (objects of class
2182 "phylo") in an ASCII file using the Newick parenthetic format.
2184 o The function birthdeath() fits a birth-death model to branching times
2185 by maximum likelihood, and estimates the corresponding speciation and
2188 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2191 o The function is.binary.tree() tests whether a phylogeny is binary.
2193 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2194 as well as some methods are introduced.
2196 o Several functions, including some generics and methods, for computing
2197 skyline plot estimates (classic and generalized) of effective
2198 population size through time are introduced and replace the function
2199 skyline.plot() in version 0.1.
2201 o Two data sets are now included: the phylogenetic relationships among
2202 the families of birds from Sibley and Ahlquist (1990), and an
2203 estimated clock-like phylogeny of HIV sequences sampled in the
2204 Democratic Republic of Congo.
2207 DEPRECATED & DEFUNCT
2209 o The function skyline.plot() in ape 0.1 has been deprecated and
2210 replaced by more elaborate functions (see above).
2215 o Two important bugs were fixed in plot.phylo(): phylogenies with
2216 multichotomies not at the root or not with only terminal branches,
2217 and phylogenies with a single node (i.e. only terminal branches)
2218 did not plot. These trees should be plotted correctly now.
2220 o Several bugs were fixed in diversi.time() in the computation of
2223 o Various errors were corrected in the help pages.
