227 'interactive' option to make the operation on a plotted tree.
229 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
230 association links; they are recycled like 'col' (which wasn't before).
235 o rTraitDisc() did not use its 'freq' argument correctly (it was
236 multiplied with the rate matrix column-wise instead of row-wise).

257 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
258 the sequences are correctly stored (in a list for c, in a matrix
259 for the two other functions).
263 CHANGES IN APE VERSION 2.5
268 o The new function parafit by Pierre Legendre tests for the

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

332 o read.nexus() shuffled tip labels when the trees have no branch
333 lengths and there is a TRANSLATE block.
335 o read.nexus() does not try to translate node labels if there is a
336 translation table in the NEXUS file. See ?read.nexus for a
337 clarification on this behaviour.

382 been modified (as well as their widths and types) following some
383 users' request; this is only for dichotomous nodes.
385 o The argument 'adj' in [node][tip][edge]labels() now works when
386 using 'pie' or 'thermo'.
388 o A more informative message error is now returned by dist.dna() when

467 to be treated as (un)rooted.
472 o dist.gene() failed on most occasions with the default

618 'check.labels = TRUE'.
620 o summary.DNAbin() failed to display correctly the summary of
621 sequence lengths with lists of sequences of 10,000 bases or more

791 o read.tree() and read.nexus() now return an unnamed list if
794 o read.nexus() now returns a modified object of class "multiPhylo"
795 when there is a TRANSLATE block in the NEXUS file: the individual

852 details). A legend is now plotted by default.
857 o dist.dna() returned some incorrect values with `model = "JC69"'
858 and `pairwise.deletion = TRUE'. This affected only the
859 distances involving sequences with missing values. (Thanks
860 to Bruno Toupance for digging this bug out.)
862 o write.tree() failed with some trees: this is fixed by removing
863 the `multi.line' option (trees are now always printed on a
866 o read.nexus() did not correctly detect trees with multiple root
867 edges (see OTHER CHANGES).

964 easily DNA sequences stored in a list into a matrix while
965 keeping the names and the class.
970 o chronopl() failed when some branch lengths were equal to zero:
971 an error message is now returned.
973 o di2multi() failed when there was a series of consecutive edges
978 CHANGES IN APE VERSION 1.10-2
983 o plot.phylo() can now plot circular trees: the option is type =
984 "fan" or type = "f" (to avoid the ambiguity with type = "c").
986 o prop.part() has a new option `check.labels = FALSE' which allows
987 to considerably speed-up the calculations of bipartitions. As a
988 consequence, calculations of bootstrap values with boot.phylo()
989 should be much faster.
994 o read.GenBank() did not return correctly the list of species as
995 from ape 1.10: this is fixed in this version
997 o Applying as.phylo() on a tree of class "phylo" failed: the
998 object is now returned unchanged.
1002 CHANGES IN APE VERSION 1.10-1
1007 o The three new functions Ntip, Nnode, and Nedge return, for a
1008 given tree, the number of tips, nodes, or edges, respectively.
1013 o read.nexus() did not set correctly the class of the returned
1014 object when reading multiple trees.
1016 o mllt.plot() failed with objects of class c("multi.tree",
1019 o unroot() did not work correctly in most cases.
1021 o reorder.phylo() made R freeze in some occasions.
1023 o Plotting a tree in pruningwise order failed.
1025 o When plotting an unrooted tree, the tip labels where not all
1026 correctly positioned if the option `cex' was used.
1030 CHANGES IN APE VERSION 1.10
1035 o Five new `method' functions have been introduced to manipulate
1036 DNA sequences in binary format (see below).
1038 o Three new functions have been introduced to convert between the
1039 new binary and the character formats.
1041 o The new function as.alignment converts DNA sequences stored as
1042 single characters into the class "alignment" used by the package
1045 o read.dna() and read.GenBank() have a new argument `as.character'
1046 controlling whether the sequences are returned in binary format
1052 o root() failed when the tree had node labels: this is fixed.
1054 o plot.phylo() did not correctly set the limits on the y-axis with
1055 the default setting: this is fixed.
1057 o dist.dna() returned a wrong result for the LogDet, paralinear,
1058 and BH87 models with `pairwise.deletion = TRUE'.
1063 o DNA sequences are now internally stored in a binary format. See
1064 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1065 details. Most functions analyzing DNA functions have been
1066 modified accordingly and are now much faster (dist.dna is now
1067 ca. 60 times faster).
1071 CHANGES IN APE VERSION 1.9-4
1076 o A bug was fixed in edgelabels().
1078 o as.phylo.hclust() did not work correctly when the object of
1079 class "hclust" has its labels set to NULL: the returned tree has
1080 now its tip labels set to "1", "2", ...
1082 o consensus could fail if some tip labels are a subset of others
1083 (e.g., "a" and "a_1"): this is now fixed.
1085 o mlphylo() failed in most cases if some branch lengths of the
1086 initial tree were greater than one: an error message is now
1089 o mlphylo() failed in most cases when estimating the proportion of
1090 invariants: this is fixed.
1094 CHANGES IN APE VERSION 1.9-3
1099 o The new function edgelabels adds labels on the edge of the tree
1100 in the same way than nodelabels or tiplabels.
1105 o multi2di() did not handle correctly branch lengths with the
1106 default option `random = TRUE': this is now fixed.
1108 o A bug was fixed in nuc.div() when using pairwise deletions.
1110 o A bug occurred in the analysis of bipartitions with large
1111 numbers of large trees, with consequences on prop.part,
1112 prop.clades, and boot.phylo.
1114 o The calculation of the Billera-Holmes-Vogtmann distance in
1115 dist.topo was wrong: this has been fixed.
1119 CHANGES IN APE VERSION 1.9-2
1124 o The new function ladderize reorganizes the internal structure of
1125 a tree to plot them left- or right-ladderized.
1127 o The new function dist.nodes computes the patristic distances
1128 between all nodes, internal and terminal, of a tree. It replaces
1129 the option `full = TRUE' of cophenetic.phylo (see below).
1134 o A bug was fixed in old2new.phylo().
1136 o Some bugs were fixed in chronopl().
1138 o The edge colours were not correctly displayed by plot.phylo
1139 (thank you to Li-San Wang for the fix).
1141 o cophenetic.phylo() failed with multichotomous trees: this is
1147 o read.dna() now returns the sequences in a matrix if they are
1148 aligned (interleaved or sequential format). Sequences in FASTA
1149 format are still returned in a list.
1151 o The option `full' of cophenetic.phylo() has been removed because
1152 it could not be used from the generic.
1155 DEPRECATED & DEFUNCT
1157 o rotate() has been removed; this function did not work correctly
1162 CHANGES IN APE VERSION 1.9-1
1167 o Trees with a single tip were not read correctly in R as the
1168 element `Nnode' was not set: this is fixed.
1170 o unroot() did not set correctly the number of nodes of the
1171 unrooted tree in most cases.
1173 o read.GenBank() failed when fetching very long sequences,
1174 particularly of the BX-series.
1176 o A bug was introduced in read.tree() with ape 1.9: it has been
1181 CHANGES IN APE VERSION 1.9
1186 o There are two new print `methods' for trees of class "phylo" and
1187 lists of trees of class "multi.tree", so that they are now
1188 displayed in a compact and informative way.
1190 o There are two new functions, old2new.phylo and new2old.phylo,
1191 for converting between the old and new coding of the class
1194 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1195 LogDet ("logdet"), and paralinear ("paralin").
1197 o compute.brlen() has been extended: several methods are now
1198 available to compute branch lengths.
1200 o write.dna() can now handle matrices as well as lists.
1205 o cophenetic.phylo() sometimes returned a wrong result with
1206 multichotomous trees: this is fixed.
1208 o rotate() failed when a single tip was specified: the tree is now
1211 o ace() did not return the correct index matrix with custom
1212 models: this is fixed.
1214 o multi2di() did not work correctly when resolving multichotomies
1215 randomly: the topology was always the same, only the arrangement
1216 of clades was randomized: this is fixed. This function now
1217 accepts trees with no branch lengths.
1219 o The output of diversi.gof() was blurred by useless prints when a
1220 user distribution was specified. This has been corrected, and
1221 the help page of this function has been expanded.
1226 o The internal structure of the class "phylo" has been changed:
1227 see the document "Definition of Formats for Coding Phylogenetic
1228 Trees in R" for the details. In addition, the code of most
1229 functions has been improved.
1231 o Several functions have been improved by replacing some R codes
1232 by C codes: pic, plot.phylo, and reorder.phylo.
1234 o There is now a citation information: see citation("ape") in R.
1236 o write.tree() now does not add extra 0's to branch lengths so
1237 that 1.23 is printed "1.23" by default, not "1.2300000000".
1239 o The syntax of bind.tree() has been simplified. This function now
1240 accepts trees with no branch lengths, and handles correctly node
1243 o The option `as.numeric' of mrca() has been removed.
1245 o The unused options `format' and `rooted' of read.tree() have
1248 o The unused option `format' of write.tree() has been removed.
1250 o The use of node.depth() has been simplified.
1254 CHANGES IN APE VERSION 1.8-5
1259 o Two new functions read.nexus.data() and write.nexus.data(),
1260 contributed by Johan Nylander, allow to read and write molecular
1261 sequences in NEXUS files.
1263 o The new function reorder.phylo() reorders the internal structure
1264 of a tree of class "phylo". It is used as the generic, e.g.,
1267 o read.tree() and read.nexus() can now read trees with a single
1270 o The new data set `cynipids' supplies a set of protein sequences
1276 o The code of all.equal.phylo() has been completely rewritten
1277 (thanks to Benoît Durand) which fixes several bugs.
1279 o read.tree() and read.nexus() now checks the labels of the tree
1280 to remove or substitute any characters that are illegal in the
1281 Newick format (parentheses, etc.)
1283 o A negative P-value could be returned by mantel.test(): this is
1288 CHANGES IN APE VERSION 1.8-4
1293 o The new function sh.test() computes the Shimodaira-
1296 o The new function collapse.singles() removes the nodes with a
1297 single descendant from a tree.
1299 o plot.phylo() has a new argument `tip.color' to specify the
1300 colours of the tips.
1302 o mlphylo() has now an option `quiet' to control the display of
1303 the progress of the analysis (the default is FALSE).
1308 o read.dna() did not read correctly sequences in sequential format
1309 with leading alignment gaps "-": this is fixed.
1311 o ace() returned a list with no class so that the generic
1312 functions (anova, logLik, ...) could not be used directly. This
1313 is fixed as ace() now returns an object of class "ace".
1315 o anova.ace() had a small bug when computing the number of degrees
1316 of freedom: this is fixed.
1318 o mlphylo() did not work when the sequences were in a matrix or
1319 a data frame: this is fixed.
1321 o rtree() did not work correctly when trying to simulate an
1322 unrooted tree with two tips: an error message is now issued.
1327 o The algorithm of rtree() has been changed: it is now about 40,
1328 100, and 130 times faster for 10, 100, and 1000 tips,
1333 CHANGES IN APE VERSION 1.8-3
1338 o There are four new `method' functions to be used with the
1339 results of ace(): logLik(), deviance(), AIC(), and anova().
1341 o The plot method of phymltest has two new arguments: `main' to
1342 change the title, and `col' to control the colour of the
1343 segments showing the AIC values.
1345 o ace() has a new argument `ip' that gives the initial values used
1346 in the ML estimation with discrete characters (see the examples
1347 in ?ace). This function now returns a matrix giving the indices
1348 of the estimated rates when analysing discrete characters.
1350 o nodelabels() and tiplabels() have a new argument `pie' to
1351 represent proportions, with any number of categories, as
1352 piecharts. The use of the option `thermo' has been improved:
1353 there is now no limitation on the number of categories.
1358 o mlphylo() did not work with more than two partitions: this is
1361 o root() failed if the proposed outgroup was already an outgroup
1362 in the tree: this is fixed.
1364 o The `col' argument in nodelabels() and tiplabels() was not
1365 correctly passed when `text' was used: this is fixed.
1367 o Two bugs were fixed in mlphylo(): parameters were not always
1368 correctly output, and the estimation failed in some cases.
1370 o plot.phylo() was stuck when given a tree with a single tip: this
1371 is fixed and a message error is now returned.
1373 o An error was corrected in the help page of gammaStat regarding
1374 the calculation of P-values.
1376 o Using gls() could crash R when the number of species in the tree
1377 and in the variables were different: this is fixed.
1381 CHANGES IN APE VERSION 1.8-2
1386 o The new function mlphylo() fits a phylogenetic tree by maximum
1387 likelihood from DNA sequences. Its companion function DNAmodel()
1388 is used to define the substitution model which may include
1389 partitioning. There are methods for logLik(), deviance(), and
1390 AIC(), and the summary() method has been extended to display in
1391 a friendly way the results of this model fitting. Currently, the
1392 functionality is limited to estimating the substitution and
1393 associated parameters and computing the likelihood.
1395 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1396 tests for single effects in GEE-based comparative method. A
1397 warning message is printed if there is not enough degrees of
1403 o An error message was sometimes issued by plot.multi.tree(),
1404 though with no consequence.
1408 CHANGES IN APE VERSION 1.8-1
1413 o There is a new plot method for lists of trees (objects of class
1414 "multi.tree"): it calls plot.phylo() internally and is
1415 documented on the same help page.
1420 o A bug was fixed in the C code that analyzes bipartitions: this
1421 has impact on several functions like prop.part, prop.clades,
1422 boot.phylo, or consensus.
1424 o root() did not work correctly when the specified outgroup had
1425 more than one element: this is fixed.
1427 o dist.dna() sometimes returned a warning inappropriately: this
1430 o If the distance object given to nj() had no rownames, nj()
1431 returned a tree with no tip labels: it now returns tips labelled
1432 "1", "2", ..., corresponding to the row numbers.
1437 o nj() has been slightly changed so that tips with a zero distance
1438 are first aggregated with zero-lengthed branches; the usual NJ
1439 procedure is then performed on a distance matrix without 0's.
1443 CHANGES IN APE VERSION 1.8
1448 o The new function chronopl() estimates dates using the penalized
1449 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1451 o The new function consensus() calculates the consensus tree of a
1454 o The new function evolve.phylo() simulates the evolution of
1455 continuous characters along a phylogeny under a Brownian model.
1457 o The new plot method for objects of class "ancestral" displays a
1458 tree together with ancestral values, as returned by the above
1461 o The new function as.phylo.formula() returns a phylogeny from a
1462 set of nested taxonomic variables given as a formula.
1464 o The new function read.caic() reads trees in CAIC format.
1466 o The new function tiplabels() allows to add labels to the tips
1467 of a tree using text or plotting symbols in a flexible way.
1469 o The new function unroot() unroots a phylogeny.
1471 o multi2di() has a new option, `random', which specifies whether
1472 to resolve the multichotomies randomly (the default) or not.
1474 o prop.part() now returns an object of class "prop.part" for which
1475 there are print (to display a partition in a more friendly way)
1476 and summary (to extract the numbers) methods.
1478 o plot.phylo() has a new option, `show.tip.label', specifying
1479 whether to print the labels of the tips. The default is TRUE.
1481 o The code of nj() has been replaced by a faster C code: it is now
1482 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1485 o write.nexus() now writes whether a tree is rooted or not.
1490 o Two bugs have been fixed in root(): unrooted trees are now
1491 handled corretly, and node labels are now output normally.
1493 o A bug was fixed in phymltest(): the executable couldn't be found
1496 o Three bug have been fixed in ace(): computing the likelihood of
1497 ancestral states of discrete characters failed, custom models
1498 did not work, and the function failed with a null gradient (a
1499 warning message is now returned; this latter bug was also
1500 present in yule.cov() as well and is now fixed).
1502 o pic() hanged out when missing data were present: a message error
1505 o A small bug was fixed in dist.dna() where the gamma correction
1506 was not always correctly dispatched.
1508 o plot.phylo() plotted correctly the root edge only when the tree
1509 was plotted rightwards: this works now for all directions.
1514 o dist.taxo() has been renamed as weight.taxo().
1516 o dist.phylo() has been replaced by the method cophenetic.phylo().
1518 o Various error and warning messages have been improved.
1522 CHANGES IN APE VERSION 1.7
1525 o The new function ace() estimates ancestral character states for
1526 continuous characters (with ML, GLS, and contrasts methods), and
1527 discrete characters (with ML only) for any number of states.
1529 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1530 of directional evolution for continuous characters. The user
1531 specifies the node(s) of the tree where the character optimum
1534 o The new function is.rooted() tests whether a tree (of class
1537 o The new function rcoal() generates random ultrametric trees with
1538 the possibility to specify the function that generates the
1539 inter-nodes distances.
1541 o The new function mrca() gives for all pairs of tips in a tree
1542 (and optionally nodes too) the most recent common ancestor.
1544 o nodelabels() has a new option `thermo' to plot proportions (up
1545 to three classes) on the nodes of a tree.
1547 o rtree() has been improved: it can now generate rooted or
1548 unrooted trees, and the mathematical function that generates the
1549 branch lengths may be specified by the user. The tip labels may
1550 be given directly in the call to rtree. The limit cases (n = 2,
1551 3) are now handled correctly.
1553 o dist.topo() has a new argument `method' with two choices: "PH85"
1554 for Penny and Henny's method (already available before and now
1555 the default), and "BHV01" for the geometric distance by Billera
1556 et al. (2001, Adv. Appl. Math. 27:733).
1558 o write.tree() has a new option, `digits', which specifies the
1559 number of digits to be printed in the Newick tree. By default
1560 digits = 10. The numbers are now always printed in decimal form
1561 (i.e., 1.0e-1 is now avoided).
1563 o dist.dna() can now compute the raw distances between pairs of
1564 DNA sequences by specifying model = "raw".
1566 o dist.phylo() has a new option `full' to possibly compute the
1567 distances among all tips and nodes of the tree. The default if
1573 o Several bugs were fixed in all.equal.phylo().
1575 o dist.dna() did not handle correctly gaps ("-") in alignments:
1576 they are now considered as missing data.
1578 o rotate() did not work if the tips were not ordered: this is
1581 o mantel.test() returned NA in some special cases: this is fixed
1582 and the function has been improved and is now faster.
1584 o A bug was fixed in diversi.gof() where the calculation of A² was
1587 o cherry() did not work correctly under some OSs (mainly Linux):
1590 o is.binary.tree() has been modified so that it works with both
1591 rooted and unrooted trees.
1593 o The documentation of theta.s() was not correct: this has been
1596 o plot.mst() did not work correctly: this is fixed.
1600 CHANGES IN APE VERSION 1.6
1605 o The new function dist.topo() computes the topological distances
1608 o The new function boot.phylo() performs a bootstrap analysis on
1609 phylogeny estimation.
1611 o The new functions prop.part() and prop.clades() analyse
1612 bipartitions from a series of trees.
1617 o read.GenBank() now uses the EFetch utility of NCBI instead of
1618 the usual Web interface: it is now much faster (e.g., 12 times
1619 faster to retrieve 8 sequences, 37 times for 60 sequences).
1624 o Several bugs were fixed in read.dna().
1626 o Several bugs were fixed in diversi.time().
1628 o is.binary.tree() did not work correctly if the tree has no edge
1629 lengths: this is fixed.
1631 o drop.tip() did not correctly propagated the `node.label' of a
1632 tree: this is fixed.
1636 CHANGES IN APE VERSION 1.5
1641 o Two new functions, as.matching.phylo() and as.phylo.matching(),
1642 convert objects between the classes "phylo" and "matching". The
1643 latter implements the representation of binary trees introduced by
1644 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
1645 as.matching() has been introduced as well.
1647 o Two new functions, multi2di() and di2multi(), allow to resolve
1648 and collapse multichotomies with branches of length zero.
1650 o The new function nuc.div() computes the nucleotide diversity
1651 from a sample a DNA sequences.
1653 o dist.dna() has been completely rewritten with a much faster
1654 (particularly for large data sets) C code. Eight models are
1655 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
1656 option `method' has been renamed `model'). Computation of variance
1657 is available for all models. A gamma-correction is possible for
1658 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
1659 to remove sites with missing data on a pairwise basis. The option
1660 `GCcontent' has been removed.
1662 o read.GenBank() has a new option (species.names) which specifies
1663 whether to return the species names of the organisms in addition
1664 to the accession numbers of the sequences (this is the default
1667 o write.nexus() can now write several trees in the same NEXUS file.
1669 o drop.tip() has a new option `root.edge' that allows to specify the
1670 new root edge if internal branches are trimmed.
1675 o as.phylo.hclust() failed if some labels had parentheses: this
1678 o Several bugs were fixed in all.equal.phylo(). This function now
1679 returns the logical TRUE if the trees are identical but with
1680 different representations (a report was printed previously).
1682 o read.GenBank() did not correctly handle ambiguous base codes:
1688 o birthdeath() now returns an object of class "birthdeath" for
1689 which there is a print method.
1693 CHANGES IN APE VERSION 1.4
1698 o The new function nj() performs phylogeny estimation with the
1699 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
1702 o The new function which.edge() identifies the edges of a tree
1703 that belong to a group specified as a set of tips.
1705 o The new function as.phylo.phylog() converts an object of class
1706 "phylog" (from the package ade4) into an object of class
1709 o The new function axisPhylo() draws axes on the side of a
1712 o The new function howmanytrees() calculates the number of trees
1713 in different cases and giving a number of tips.
1715 o write.tree() has a new option `multi.line' (TRUE by default) to
1716 write a Newick tree on several lines rather than on a single
1719 o The functionalities of zoom() have been extended. Several
1720 subtrees can be visualized at the same time, and they are marked
1721 on the main tree with colors. The context of the subtrees can be
1722 marked with the option `subtree' (see below).
1724 o drop.tip() has a new option `subtree' (FALSE by default) which
1725 specifies whether to output in the tree how many tips have been
1728 o The arguments of add.scale.bar() have been redefined and have
1729 now default values (see ?add.scale.bar for details). This
1730 function now works even if the plotted tree has no edge length.
1732 o plot.phylo() can now plot radial trees, but this does not take
1733 edge lengths into account.
1735 o In plot.phylo() with `type = "phylogram"', if the values of
1736 `edge.color' and `edge.width' are identical for sister-branches,
1737 they are propagated to the vertical line that link them.
1742 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
1743 crashing. This is fixed.
1745 o In plot.phylo(), the options `edge.color' and `edge.width' are
1746 now properly recycled; their default values are now "black" and
1749 o A bug has been fixed in write.nexus().
1754 o The function node.depth.edgelength() has been removed and
1755 replaced by a C code.
1759 CHANGES IN APE VERSION 1.3-1
1764 o The new function nodelabels() allows to add labels to the nodes
1765 of a tree using text or plotting symbols in a flexible way.
1767 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
1768 numeric values specifying the lower and upper limits on the x-
1769 and y-axes. This allows to leave some space on any side of the
1770 tree. If a single value is given, this is taken as the upper
1775 CHANGES IN APE VERSION 1.3
1780 o The new function phymltest() calls the software PHYML and fits
1781 28 models of DNA sequence evolution. There are a print method to
1782 display likelihood and AIC values, a summary method to compute
1783 the hierarchical likelihood ratio tests, and a plot method to
1784 display graphically the AIC values of each model.
1786 o The new function yule.cov() fits the Yule model with covariates,
1787 a model where the speciation rate is affected by several species
1788 traits through a generalized linear model. The parameters are
1789 estimated by maximum likelihood.
1791 o Three new functions, corBrownian(), corGrafen(), and
1792 corMartins(), compute the expected correlation structures among
1793 species given a phylogeny under different models of evolution.
1794 These can be used for GLS comparative phylogenetic methods (see
1795 the examples). There are coef() and corMatrix() methods and an
1796 Initialize.corPhyl() function associated.
1798 o The new function compar.cheverud() implements Cheverud et al.'s
1799 (1985; Evolution 39:1335) phylogenetic comparative method.
1801 o The new function varcomp() estimates variance components; it has
1804 o Two new functions, panel.superpose.correlogram() and
1805 plot.correlogramList(), allow to plot several phylogenetic
1808 o The new function node.leafnumber() computes the number of leaves
1809 of a subtree defined by a particular node.
1811 o The new function node.sons() gets all tags of son nodes from a
1814 o The new function compute.brlen() computes the branch lengths of
1815 a tree according to a specified method.
1817 o plot.phylo() has three new options: "cex" controls the size of
1818 the (tip and node) labels (thus it is no more needed to change
1819 the global graphical parameter), "direction" which allows to
1820 plot the tree rightwards, leftwards, upwards, or downwards, and
1821 "y.lim" which sets the upper limit on the y-axis.
1826 o Some functions which try to match tip labels and names of
1827 additional data (e.g. vector) are likely to fail if there are
1828 typing or syntax errors. If both series of names do not perfectly
1829 match, they are ignored and a warning message is now issued.
1830 These functions are bd.ext, compar.gee, pic. Their help pages
1831 have been clarified on this point.
1835 CHANGES IN APE VERSION 1.2-7
1840 o The new function root() reroots a phylogenetic tree with respect
1841 to a specified outgroup.
1843 o The new function rotate() rotates an internal branch of a tree.
1845 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
1846 trees) controls the display of the tip labels in unrooted trees.
1847 This display has been greatly improved: the tip labels are now not
1848 expected to overlap with the tree (particularly if lab4ut =
1849 "axial"). In all cases, combining appropriate values of "lab4ut"
1850 and the font size (via "par(cex = )") should result in readable
1851 unrooted trees. See ?plot.phylo for some examples.
1853 o In drop.tip(), the argument `tip' can now be numeric or character.
1858 o drop.tip() did not work correctly with trees with no branch
1859 lengths: this is fixed.
1861 o A bug in plot.phylo(..., type = "unrooted") made some trees being
1862 plotted with some line crossings: this is now fixed.
1866 CHANGES IN APE VERSION 1.2-6
1871 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
1872 correlogram.phylo, dist.taxo, plot.correlogram) have been added
1873 to implement comparative methods with an autocorrelation approach.
1875 o A new data set describing some life history traits of Carnivores
1881 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
1886 o When plotting a tree with plot.phylo(), the new default of the
1887 option `label.offset' is now 0, so the labels are always visible.
1891 CHANGES IN APE VERSION 1.2-5
1896 o The new function bd.ext() fits a birth-death model with combined
1897 phylogenetic and taxonomic data, and estimates the corresponding
1898 speciation and extinction rates.
1903 o The package gee is no more required by ape but only suggested
1904 since only the function compar.gee() calls gee.
1908 CHANGES IN APE VERSION 1.2-4
1913 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
1914 and lines.popsize) implementing a new approach for inferring the
1915 demographic history from genealogies using a reversible jump
1916 MCMC have been introduced.
1918 o The unit of time in the skyline plot and in the new plots can
1919 now be chosen to be actual years, rather than substitutions.
1923 CHANGES IN APE VERSION 1.2-3
1928 o The new function rtree() generates a random binary tree with or
1929 without branch lengths.
1931 o Two new functions for drawing lineages-through-time (LTT) plots
1932 are provided: ltt.lines() adds a LTT curve to an existing plot,
1933 and mltt.plot() does a multiple LTT plot giving several trees as
1934 arguments (see `?ltt.plot' for details).
1939 o Some taxon names made R crashing when calling as.phylo.hclust():
1942 o dist.dna() returned an error with two identical DNA sequences
1943 (only using the Jukes-Cantor method returned 0): this is fixed.
1948 o The function dist.phylo() has been re-written using a different
1949 algorithm: it is now about four times faster.
1951 o The code of branching.times() has been improved: it is now about
1956 CHANGES IN APE VERSION 1.2-2
1961 o The new function seg.sites() finds the segregating sites in a
1962 sample of DNA sequences.
1967 o A bug introduced in read.tree() and in read.nexus() with version
1970 o A few errors were corrected and a few examples were added in the
1975 CHANGES IN APE VERSION 1.2-1
1980 o plot.phylo() can now draw the edge of the root of a tree if it
1981 has one (see the new option `root.edge', its default is FALSE).
1986 o A bug was fixed in read.nexus(): files with semicolons inside
1987 comment blocks were not read correctly.
1989 o The behaviour of read.tree() and read.nexus() was corrected so
1990 that tree files with badly represented root edges (e.g., with
1991 an extra pair of parentheses, see the help pages for details)
1992 are now correctly represented in the object of class "phylo";
1993 a warning message is now issued.
1997 CHANGES IN APE VERSION 1.2
2002 o plot.phylo() has been completely re-written and offers several
2003 new functionalities. Three types of trees can now be drawn:
2004 phylogram (as previously), cladogram, and unrooted tree; in
2005 all three types the branch lengths can be drawn using the edge
2006 lengths of the phylogeny or not (e.g., if the latter is absent).
2007 The vertical position of the nodes can be adjusted with two
2008 choices (see option `node.pos'). The code has been re-structured,
2009 and two new functions (potentially useful for developpers) are
2010 documented separately: node.depth.edgelength() and node.depth();
2011 see the respective help pages for details.
2013 o The new function zoom() allows to explore very large trees by
2014 focusing on a small portion of it.
2016 o The new function yule() fits by maximum likelihood the Yule model
2017 (birth-only process) to a phylogenetic tree.
2019 o Support for writing DNA sequences in FASTA format has been
2020 introduced in write.dna() (support for reading sequences in
2021 this format was introduced in read.dna() in version 1.1-2).
2022 The function has been completely re-written, fixing some bugs
2023 (see below); the default behaviour is no more to display the
2024 sequences on the standard output. Several options have been
2025 introduced to control the sequence printing in a flexible
2026 way. The help page has been extended.
2028 o A new data set is included: a supertree of bats in NEXUS format.
2033 o In theta.s(), the default of the option `variance' has
2034 been changed to `FALSE' (as was indicated in the help page).
2036 o Several bugs were fixed in the code of all.equal.phylo().
2038 o Several bugs were fixed in write.dna(), particularly this
2039 function did not work with `format = "interleaved"'.
2041 o Various errors were corrected in the help pages.
2046 o The argument names of as.hclust.phylo() have been changed
2047 from "(phy)" to "(x, ...)" to conform to the definition of
2048 the corresponding generic function.
2050 o gamma.stat() has been renamed gammaStat() to avoid confusion
2051 since gamma() is a generic function.
2055 CHANGES IN APE VERSION 1.1-3
2060 o base.freq() previously did not return a value of 0 for
2061 bases absent in the data (e.g., a vector of length 3 was
2062 returned if one base was absent). This is now fixed (a
2063 vector of length 4 is always returned).
2065 o Several bugs were fixed in read.nexus(), including that this
2066 function did not work in this absence of a "TRANSLATE"
2067 command in the NEXUS file, and that the commands were
2072 CHANGES IN APE VERSION 1.1-2
2077 o The Tamura and Nei (1993) model of DNA distance is now implemented
2078 in dist.dna(): five models are now available in this function.
2080 o A new data set is included: a set of 15 sequences of the
2081 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2087 o A bug in read.nexus() was fixed.
2089 o read.dna() previously did not work correctly in most cases.
2090 The function has been completely re-written and its help page
2091 has been considerably extended (see ?read.dna for details).
2092 Underscores (_) in taxon names are no more replaced with
2093 spaces (this behaviour was undocumented).
2095 o A bug was fixed in write.dna().
2099 CHANGES IN APE VERSION 1.1-1
2104 o A bug in read.tree() introduced in APE 1.1 was fixed.
2106 o A bug in compar.gee() resulted in an error when trying to fit
2107 a model with `family = "binomial"'. This is now fixed.
2111 CHANGES IN APE VERSION 1.1
2116 o The Klastorin (1982) method as suggested by Misawa and Tajima
2117 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2118 on the basis of phylogenetic trees has been implemented (see
2119 the function klastorin()).
2121 o Functions have been added to convert APE's "phylo" objects in
2122 "hclust" cluster objects and vice versa (see the help page of
2123 as.phylo for details).
2125 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2126 are introduced for the estimation of absolute evolutionary rates
2127 (ratogram) and dated clock-like trees (chronogram) from
2128 phylogenetic trees using the non-parametric rate smoothing approach
2129 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2131 o A summary method is now provided printing a summary information on a
2132 phylogenetic tree with, for instance, `summary(tree)'.
2134 o The behaviour of read.tree() was changed so that all spaces and
2135 tabulations in tree files are now ignored. Consequently, spaces in tip
2136 labels are no more allowed. Another side effect is that read.nexus()
2137 now does not replace the underscores (_) in tip labels with spaces
2138 (this behaviour was undocumented).
2140 o The function plot.phylo() has a new option (`underscore') which
2141 specifies whether the underscores in tip labels should be written on
2142 the plot as such or replaced with spaces (the default).
2144 o The function birthdeath() now computes 95% confidence intervals of
2145 the estimated parameters using profile likelihood.
2147 o Three new data sets are included: a gene tree estimated from 36
2148 landplant rbcL sequences, a gene tree estimated from 32 opsin
2149 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2154 o A bug was fixed in dist.gene() where nothing was returned.
2156 o A bug in plot.mst() was fixed.
2158 o A bug in vcv.phylo() resulted in false correlations when the
2159 option `cor = TRUE' was used (now fixed).
2163 CHANGES IN APE VERSION 1.0
2168 o Two new functions, read.dna() and write.dna(), read/write in a file
2169 DNA sequences in interleaved or in sequential format.
2171 o Two new functions, read.nexus() and write.nexus(), read/write trees
2174 o The new function bind.tree() allows to bind two trees together,
2175 possibly handling root edges to give internal branches.
2177 o The new function drop.tip() removes the tips in a phylogenetic tree,
2178 and trims (or not) the corresponding internal branches.
2180 o The new function is.ultrametric() tests if a tree is ultrametric.
2182 o The function plot.phylo() has more functionalities such as drawing the
2183 branches with different colours and/or different widths, showing the
2184 node labels, controling the position and font of the labels, rotating
2185 the labels, and controling the space around the plot.
2187 o The function read.tree() can now read trees with no branch length,
2188 such as "(a,b),c);". Consequently, the element `edge.length' in
2189 objects of class "phylo" is now optional.
2191 o The function write.tree() has a new default behaviour: if the default
2192 for the option `file' is used (i.e. file = ""), then a variable of
2193 mode character containing the tree in Newick format is returned which
2194 can thus be assigned (e.g., tree <- write.tree(phy)).
2196 o The function read.tree() has a new argument `text' which allows
2197 to read the tree in a variable of mode character.
2199 o A new data set is included: the phylogenetic relationships among
2200 the orders of birds from Sibley and Ahlquist (1990).
2204 CHANGES IN APE VERSION 0.2-1
2209 o Several bugs were fixed in the help pages.
2213 CHANGES IN APE VERSION 0.2
2218 o The function write.tree() writes phylogenetic trees (objects of class
2219 "phylo") in an ASCII file using the Newick parenthetic format.
2221 o The function birthdeath() fits a birth-death model to branching times
2222 by maximum likelihood, and estimates the corresponding speciation and
2225 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2228 o The function is.binary.tree() tests whether a phylogeny is binary.
2230 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2231 as well as some methods are introduced.
2233 o Several functions, including some generics and methods, for computing
2234 skyline plot estimates (classic and generalized) of effective
2235 population size through time are introduced and replace the function
2236 skyline.plot() in version 0.1.
2238 o Two data sets are now included: the phylogenetic relationships among
2239 the families of birds from Sibley and Ahlquist (1990), and an
2240 estimated clock-like phylogeny of HIV sequences sampled in the
2241 Democratic Republic of Congo.
2244 DEPRECATED & DEFUNCT
2246 o The function skyline.plot() in ape 0.1 has been deprecated and
2247 replaced by more elaborate functions (see above).
2252 o Two important bugs were fixed in plot.phylo(): phylogenies with
2253 multichotomies not at the root or not with only terminal branches,
2254 and phylogenies with a single node (i.e. only terminal branches)
2255 did not plot. These trees should be plotted correctly now.
2257 o Several bugs were fixed in diversi.time() in the computation of
2260 o Various errors were corrected in the help pages.
