323 'check.labels = TRUE'.
325 o summary.DNAbin() failed to display correctly the summary of
326 sequence lengths with lists of sequences of 10,000 bases or more
327 (because summary.default uses 4 significant digits by default).

330 breaks in the Newick string.
332 o del.gaps() returned a list of empty sequences when there were no

481 o mltt.plot() failed to display the legend with an unnamed
484 o nodelabels() with pies now correcly uses the argument
485 'cex' to draw symbols of different sizes (which has
486 worked already for thermometers).

553 as its main argument.
555 o plot.correlogram() and plot.correlogramList() have been
556 improved, and gain several options (see the help page for
557 details). A legend is now plotted by default.
562 o dist.dna() returned some incorrect values with `model = "JC69"'
563 and `pairwise.deletion = TRUE'. This affected only the
564 distances involving sequences with missing values. (Thanks
565 to Bruno Toupance for digging this bug out.)
567 o write.tree() failed with some trees: this is fixed by removing
568 the `multi.line' option (trees are now always printed on a
571 o read.nexus() did not correctly detect trees with multiple root
572 edges (see OTHER CHANGES).
577 o The code of mlphylo() has been almost entirely rewritten, and

646 limited number of labelled topologies could be generated.
650 CHANGES IN APE VERSION 2.0-1
655 o The three new functions bionj, fastme.ols, and fastme.bal
656 perform phylogeny estimation by the BIONJ and fastME methods in

669 easily DNA sequences stored in a list into a matrix while
670 keeping the names and the class.
675 o chronopl() failed when some branch lengths were equal to zero:
676 an error message is now returned.
678 o di2multi() failed when there was a series of consecutive edges
683 CHANGES IN APE VERSION 1.10-2
688 o plot.phylo() can now plot circular trees: the option is type =
689 "fan" or type = "f" (to avoid the ambiguity with type = "c").
691 o prop.part() has a new option `check.labels = FALSE' which allows
692 to considerably speed-up the calculations of bipartitions. As a
693 consequence, calculations of bootstrap values with boot.phylo()
694 should be much faster.
699 o read.GenBank() did not return correctly the list of species as
700 from ape 1.10: this is fixed in this version

763 and BH87 models with `pairwise.deletion = TRUE'.
768 o DNA sequences are now internally stored in a binary format. See
769 the document "A Bit-Level Coding Scheme for Nucleotides" for the
770 details. Most functions analyzing DNA functions have been
771 modified accordingly and are now much faster (dist.dna is now
772 ca. 60 times faster).
776 CHANGES IN APE VERSION 1.9-4
781 o A bug was fixed in edgelabels().
783 o as.phylo.hclust() did not work correctly when the object of

791 initial tree were greater than one: an error message is now
794 o mlphylo() failed in most cases when estimating the proportion of
795 invariants: this is fixed.
799 CHANGES IN APE VERSION 1.9-3
804 o The new function edgelabels adds labels on the edge of the tree
805 in the same way than nodelabels or tiplabels.
810 o multi2di() did not handle correctly branch lengths with the
811 default option `random = TRUE': this is now fixed.
813 o A bug was fixed in nuc.div() when using pairwise deletions.
815 o A bug occurred in the analysis of bipartitions with large
816 numbers of large trees, with consequences on prop.part,
817 prop.clades, and boot.phylo.

846 o cophenetic.phylo() failed with multichotomous trees: this is
852 o read.dna() now returns the sequences in a matrix if they are
853 aligned (interleaved or sequential format). Sequences in FASTA
854 format are still returned in a list.
856 o The option `full' of cophenetic.phylo() has been removed because
857 it could not be used from the generic.
862 o rotate() has been removed; this function did not work correctly
867 CHANGES IN APE VERSION 1.9-1
872 o Trees with a single tip were not read correctly in R as the

875 o unroot() did not set correctly the number of nodes of the
876 unrooted tree in most cases.
878 o read.GenBank() failed when fetching very long sequences,
879 particularly of the BX-series.

896 for converting between the old and new coding of the class
899 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
900 LogDet ("logdet"), and paralinear ("paralin").

916 o ace() did not return the correct index matrix with custom
917 models: this is fixed.
919 o multi2di() did not work correctly when resolving multichotomies
920 randomly: the topology was always the same, only the arrangement
921 of clades was randomized: this is fixed. This function now
922 accepts trees with no branch lengths.
924 o The output of diversi.gof() was blurred by useless prints when a
925 user distribution was specified. This has been corrected, and
926 the help page of this function has been expanded.
931 o The internal structure of the class "phylo" has been changed:
932 see the document "Definition of Formats for Coding Phylogenetic
933 Trees in R" for the details. In addition, the code of most
934 functions has been improved.
936 o Several functions have been improved by replacing some R codes
937 by C codes: pic, plot.phylo, and reorder.phylo.
939 o There is now a citation information: see citation("ape") in R.
941 o write.tree() now does not add extra 0's to branch lengths so
942 that 1.23 is printed "1.23" by default, not "1.2300000000".
944 o The syntax of bind.tree() has been simplified. This function now
945 accepts trees with no branch lengths, and handles correctly node
948 o The option `as.numeric' of mrca() has been removed.
950 o The unused options `format' and `rooted' of read.tree() have
953 o The unused option `format' of write.tree() has been removed.

1005 colours of the tips.
1007 o mlphylo() has now an option `quiet' to control the display of
1008 the progress of the analysis (the default is FALSE).
1013 o read.dna() did not read correctly sequences in sequential format
1014 with leading alignment gaps "-": this is fixed.
1016 o ace() returned a list with no class so that the generic
1017 functions (anova, logLik, ...) could not be used directly. This
1018 is fixed as ace() now returns an object of class "ace".
1020 o anova.ace() had a small bug when computing the number of degrees
1021 of freedom: this is fixed.
1023 o mlphylo() did not work when the sequences were in a matrix or
1024 a data frame: this is fixed.
1026 o rtree() did not work correctly when trying to simulate an
1027 unrooted tree with two tips: an error message is now issued.
1032 o The algorithm of rtree() has been changed: it is now about 40,
1033 100, and 130 times faster for 10, 100, and 1000 tips,
1038 CHANGES IN APE VERSION 1.8-3
1043 o There are four new `method' functions to be used with the
1044 results of ace(): logLik(), deviance(), AIC(), and anova().
1046 o The plot method of phymltest has two new arguments: `main' to
1047 change the title, and `col' to control the colour of the
1048 segments showing the AIC values.
1050 o ace() has a new argument `ip' that gives the initial values used
1051 in the ML estimation with discrete characters (see the examples
1052 in ?ace). This function now returns a matrix giving the indices
1053 of the estimated rates when analysing discrete characters.
1055 o nodelabels() and tiplabels() have a new argument `pie' to
1056 represent proportions, with any number of categories, as
1057 piecharts. The use of the option `thermo' has been improved:
1058 there is now no limitation on the number of categories.
1063 o mlphylo() did not work with more than two partitions: this is
1066 o root() failed if the proposed outgroup was already an outgroup
1067 in the tree: this is fixed.
1069 o The `col' argument in nodelabels() and tiplabels() was not
1070 correctly passed when `text' was used: this is fixed.
1072 o Two bugs were fixed in mlphylo(): parameters were not always
1073 correctly output, and the estimation failed in some cases.
1075 o plot.phylo() was stuck when given a tree with a single tip: this
1076 is fixed and a message error is now returned.
1078 o An error was corrected in the help page of gammaStat regarding
1079 the calculation of P-values.
1081 o Using gls() could crash R when the number of species in the tree
1082 and in the variables were different: this is fixed.
1086 CHANGES IN APE VERSION 1.8-2
1091 o The new function mlphylo() fits a phylogenetic tree by maximum
1092 likelihood from DNA sequences. Its companion function DNAmodel()
1093 is used to define the substitution model which may include
1094 partitioning. There are methods for logLik(), deviance(), and
1095 AIC(), and the summary() method has been extended to display in
1096 a friendly way the results of this model fitting. Currently, the
1097 functionality is limited to estimating the substitution and
1098 associated parameters and computing the likelihood.
1100 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1101 tests for single effects in GEE-based comparative method. A
1102 warning message is printed if there is not enough degrees of
1108 o An error message was sometimes issued by plot.multi.tree(),
1109 though with no consequence.
1113 CHANGES IN APE VERSION 1.8-1
1118 o There is a new plot method for lists of trees (objects of class
1119 "multi.tree"): it calls plot.phylo() internally and is
1120 documented on the same help page.
1125 o A bug was fixed in the C code that analyzes bipartitions: this
1126 has impact on several functions like prop.part, prop.clades,
1127 boot.phylo, or consensus.
1129 o root() did not work correctly when the specified outgroup had
1130 more than one element: this is fixed.
1132 o dist.dna() sometimes returned a warning inappropriately: this
1135 o If the distance object given to nj() had no rownames, nj()
1136 returned a tree with no tip labels: it now returns tips labelled
1137 "1", "2", ..., corresponding to the row numbers.
1142 o nj() has been slightly changed so that tips with a zero distance
1143 are first aggregated with zero-lengthed branches; the usual NJ
1144 procedure is then performed on a distance matrix without 0's.
1148 CHANGES IN APE VERSION 1.8
1153 o The new function chronopl() estimates dates using the penalized
1154 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1156 o The new function consensus() calculates the consensus tree of a
1159 o The new function evolve.phylo() simulates the evolution of
1160 continuous characters along a phylogeny under a Brownian model.
1162 o The new plot method for objects of class "ancestral" displays a
1163 tree together with ancestral values, as returned by the above
1166 o The new function as.phylo.formula() returns a phylogeny from a
1167 set of nested taxonomic variables given as a formula.
1169 o The new function read.caic() reads trees in CAIC format.
1171 o The new function tiplabels() allows to add labels to the tips
1172 of a tree using text or plotting symbols in a flexible way.
1174 o The new function unroot() unroots a phylogeny.
1176 o multi2di() has a new option, `random', which specifies whether
1177 to resolve the multichotomies randomly (the default) or not.
1179 o prop.part() now returns an object of class "prop.part" for which
1180 there are print (to display a partition in a more friendly way)
1181 and summary (to extract the numbers) methods.
1183 o plot.phylo() has a new option, `show.tip.label', specifying
1184 whether to print the labels of the tips. The default is TRUE.
1186 o The code of nj() has been replaced by a faster C code: it is now
1187 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1190 o write.nexus() now writes whether a tree is rooted or not.
1195 o Two bugs have been fixed in root(): unrooted trees are now
1196 handled corretly, and node labels are now output normally.
1198 o A bug was fixed in phymltest(): the executable couldn't be found
1201 o Three bug have been fixed in ace(): computing the likelihood of
1202 ancestral states of discrete characters failed, custom models
1203 did not work, and the function failed with a null gradient (a
1204 warning message is now returned; this latter bug was also
1205 present in yule.cov() as well and is now fixed).
1207 o pic() hanged out when missing data were present: a message error
1210 o A small bug was fixed in dist.dna() where the gamma correction
1211 was not always correctly dispatched.
1213 o plot.phylo() plotted correctly the root edge only when the tree
1214 was plotted rightwards: this works now for all directions.
1219 o dist.taxo() has been renamed as weight.taxo().
1221 o Various error and warning messages have been improved.
1225 CHANGES IN APE VERSION 1.7
1228 o The new function ace() estimates ancestral character states for
1229 continuous characters (with ML, GLS, and contrasts methods), and
1230 discrete characters (with ML only) for any number of states.
1232 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1233 of directional evolution for continuous characters. The user
1234 specifies the node(s) of the tree where the character optimum
1237 o The new function is.rooted() tests whether a tree (of class
1240 o The new function rcoal() generates random ultrametric trees with
1241 the possibility to specify the function that generates the
1242 inter-nodes distances.
1244 o The new function mrca() gives for all pairs of tips in a tree
1245 (and optionally nodes too) the most recent common ancestor.
1247 o nodelabels() has a new option `thermo' to plot proportions (up
1248 to three classes) on the nodes of a tree.
1250 o rtree() has been improved: it can now generate rooted or
1251 unrooted trees, and the mathematical function that generates the
1252 branch lengths may be specified by the user. The tip labels may
1253 be given directly in the call to rtree. The limit cases (n = 2,
1254 3) are now handled correctly.
1256 o dist.topo() has a new argument `method' with two choices: "PH85"
1257 for Penny and Henny's method (already available before and now
1258 the default), and "BHV01" for the geometric distance by Billera
1259 et al. (2001, Adv. Appl. Math. 27:733).
1261 o write.tree() has a new option, `digits', which specifies the
1262 number of digits to be printed in the Newick tree. By default
1263 digits = 10. The numbers are now always printed in decimal form
1264 (i.e., 1.0e-1 is now avoided).
1266 o dist.dna() can now compute the raw distances between pairs of
1267 DNA sequences by specifying model = "raw".
1269 o dist.phylo() has a new option `full' to possibly compute the
1270 distances among all tips and nodes of the tree. The default if
1276 o Several bugs were fixed in all.equal.phylo().
1278 o dist.dna() did not handle correctly gaps ("-") in alignments:
1279 they are now considered as missing data.
1281 o rotate() did not work if the tips were not ordered: this is
1284 o mantel.test() returned NA in some special cases: this is fixed
1285 and the function has been improved and is now faster.
1287 o A bug was fixed in diversi.gof() where the calculation of A² was
1290 o cherry() did not work correctly under some OSs (mainly Linux):
1293 o is.binary.tree() has been modified so that it works with both
1294 rooted and unrooted trees.
1296 o The documentation of theta.s() was not correct: this has been
1299 o plot.mst() did not work correctly: this is fixed.
1303 CHANGES IN APE VERSION 1.6
1308 o The new function dist.topo() computes the topological distances
1311 o The new function boot.phylo() performs a bootstrap analysis on
1312 phylogeny estimation.
1314 o The new functions prop.part() and prop.clades() analyse
1315 bipartitions from a series of trees.
1320 o read.GenBank() now uses the EFetch utility of NCBI instead of
1321 the usual Web interface: it is now much faster (e.g., 12 times
1322 faster to retrieve 8 sequences, 37 times for 60 sequences).
1327 o Several bugs were fixed in read.dna().
1329 o Several bugs were fixed in diversi.time().
1331 o is.binary.tree() did not work correctly if the tree has no edge
1332 lengths: this is fixed.
1334 o drop.tip() did not correctly propagated the `node.label' of a
1335 tree: this is fixed.
1339 CHANGES IN APE VERSION 1.5
1344 o Two new functions, as.matching.phylo() and as.phylo.matching(),
1345 convert objects between the classes "phylo" and "matching". The
1346 latter implements the representation of binary trees introduced by
1347 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
1348 as.matching() has been introduced as well.
1350 o Two new functions, multi2di() and di2multi(), allow to resolve
1351 and collapse multichotomies with branches of length zero.
1353 o The new function nuc.div() computes the nucleotide diversity
1354 from a sample a DNA sequences.
1356 o dist.dna() has been completely rewritten with a much faster
1357 (particularly for large data sets) C code. Eight models are
1358 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
1359 option `method' has been renamed `model'). Computation of variance
1360 is available for all models. A gamma-correction is possible for
1361 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
1362 to remove sites with missing data on a pairwise basis. The option
1363 `GCcontent' has been removed.
1365 o read.GenBank() has a new option (species.names) which specifies
1366 whether to return the species names of the organisms in addition
1367 to the accession numbers of the sequences (this is the default
1370 o write.nexus() can now write several trees in the same NEXUS file.
1372 o drop.tip() has a new option `root.edge' that allows to specify the
1373 new root edge if internal branches are trimmed.
1378 o as.phylo.hclust() failed if some labels had parentheses: this
1381 o Several bugs were fixed in all.equal.phylo(). This function now
1382 returns the logical TRUE if the trees are identical but with
1383 different representations (a report was printed previously).
1385 o read.GenBank() did not correctly handle ambiguous base codes:
1391 o birthdeath() now returns an object of class "birthdeath" for
1392 which there is a print method.
1396 CHANGES IN APE VERSION 1.4
1401 o The new function nj() performs phylogeny estimation with the
1402 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
1405 o The new function which.edge() identifies the edges of a tree
1406 that belong to a group specified as a set of tips.
1408 o The new function as.phylo.phylog() converts an object of class
1409 "phylog" (from the package ade4) into an object of class
1412 o The new function axisPhylo() draws axes on the side of a
1415 o The new function howmanytrees() calculates the number of trees
1416 in different cases and giving a number of tips.
1418 o write.tree() has a new option `multi.line' (TRUE by default) to
1419 write a Newick tree on several lines rather than on a single
1422 o The functionalities of zoom() have been extended. Several
1423 subtrees can be visualized at the same time, and they are marked
1424 on the main tree with colors. The context of the subtrees can be
1425 marked with the option `subtree' (see below).
1427 o drop.tip() has a new option `subtree' (FALSE by default) which
1428 specifies whether to output in the tree how many tips have been
1431 o The arguments of add.scale.bar() have been redefined and have
1432 now default values (see ?add.scale.bar for details). This
1433 function now works even if the plotted tree has no edge length.
1435 o plot.phylo() can now plot radial trees, but this does not take
1436 edge lengths into account.
1438 o In plot.phylo() with `type = "phylogram"', if the values of
1439 `edge.color' and `edge.width' are identical for sister-branches,
1440 they are propagated to the vertical line that link them.
1445 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
1446 crashing. This is fixed.
1448 o In plot.phylo(), the options `edge.color' and `edge.width' are
1449 now properly recycled; their default values are now "black" and
1452 o A bug has been fixed in write.nexus().
1457 o The function node.depth.edgelength() has been removed and
1458 replaced by a C code.
1462 CHANGES IN APE VERSION 1.3-1
1467 o The new function nodelabels() allows to add labels to the nodes
1468 of a tree using text or plotting symbols in a flexible way.
1470 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
1471 numeric values specifying the lower and upper limits on the x-
1472 and y-axes. This allows to leave some space on any side of the
1473 tree. If a single value is given, this is taken as the upper
1478 CHANGES IN APE VERSION 1.3
1483 o The new function phymltest() calls the software PHYML and fits
1484 28 models of DNA sequence evolution. There are a print method to
1485 display likelihood and AIC values, a summary method to compute
1486 the hierarchical likelihood ratio tests, and a plot method to
1487 display graphically the AIC values of each model.
1489 o The new function yule.cov() fits the Yule model with covariates,
1490 a model where the speciation rate is affected by several species
1491 traits through a generalized linear model. The parameters are
1492 estimated by maximum likelihood.
1494 o Three new functions, corBrownian(), corGrafen(), and
1495 corMartins(), compute the expected correlation structures among
1496 species given a phylogeny under different models of evolution.
1497 These can be used for GLS comparative phylogenetic methods (see
1498 the examples). There are coef() and corMatrix() methods and an
1499 Initialize.corPhyl() function associated.
1501 o The new function compar.cheverud() implements Cheverud et al.'s
1502 (1985; Evolution 39:1335) phylogenetic comparative method.
1504 o The new function varcomp() estimates variance components; it has
1507 o Two new functions, panel.superpose.correlogram() and
1508 plot.correlogramList(), allow to plot several phylogenetic
1511 o The new function node.leafnumber() computes the number of leaves
1512 of a subtree defined by a particular node.
1514 o The new function node.sons() gets all tags of son nodes from a
1517 o The new function compute.brlen() computes the branch lengths of
1518 a tree according to a specified method.
1520 o plot.phylo() has three new options: "cex" controls the size of
1521 the (tip and node) labels (thus it is no more needed to change
1522 the global graphical parameter), "direction" which allows to
1523 plot the tree rightwards, leftwards, upwards, or downwards, and
1524 "y.lim" which sets the upper limit on the y-axis.
1529 o Some functions which try to match tip labels and names of
1530 additional data (e.g. vector) are likely to fail if there are
1531 typing or syntax errors. If both series of names do not perfectly
1532 match, they are ignored and a warning message is now issued.
1533 These functions are bd.ext, compar.gee, pic. Their help pages
1534 have been clarified on this point.
1538 CHANGES IN APE VERSION 1.2-7
1543 o The new function root() reroots a phylogenetic tree with respect
1544 to a specified outgroup.
1546 o The new function rotate() rotates an internal branch of a tree.
1548 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
1549 trees) controls the display of the tip labels in unrooted trees.
1550 This display has been greatly improved: the tip labels are now not
1551 expected to overlap with the tree (particularly if lab4ut =
1552 "axial"). In all cases, combining appropriate values of "lab4ut"
1553 and the font size (via "par(cex = )") should result in readable
1554 unrooted trees. See ?plot.phylo for some examples.
1556 o In drop.tip(), the argument `tip' can now be numeric or character.
1561 o drop.tip() did not work correctly with trees with no branch
1562 lengths: this is fixed.
1564 o A bug in plot.phylo(..., type = "unrooted") made some trees being
1565 plotted with some line crossings: this is now fixed.
1569 CHANGES IN APE VERSION 1.2-6
1574 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
1575 correlogram.phylo, dist.taxo, plot.correlogram) have been added
1576 to implement comparative methods with an autocorrelation approach.
1578 o A new data set describing some life history traits of Carnivores
1584 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
1589 o When plotting a tree with plot.phylo(), the new default of the
1590 option `label.offset' is now 0, so the labels are always visible.
1594 CHANGES IN APE VERSION 1.2-5
1599 o The new function bd.ext() fits a birth-death model with combined
1600 phylogenetic and taxonomic data, and estimates the corresponding
1601 speciation and extinction rates.
1606 o The package gee is no more required by ape but only suggested
1607 since only the function compar.gee() calls gee.
1611 CHANGES IN APE VERSION 1.2-4
1616 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
1617 and lines.popsize) implementing a new approach for inferring the
1618 demographic history from genealogies using a reversible jump
1619 MCMC have been introduced.
1621 o The unit of time in the skyline plot and in the new plots can
1622 now be chosen to be actual years, rather than substitutions.
1626 CHANGES IN APE VERSION 1.2-3
1631 o The new function rtree() generates a random binary tree with or
1632 without branch lengths.
1634 o Two new functions for drawing lineages-through-time (LTT) plots
1635 are provided: ltt.lines() adds a LTT curve to an existing plot,
1636 and mltt.plot() does a multiple LTT plot giving several trees as
1637 arguments (see `?ltt.plot' for details).
1642 o Some taxon names made R crashing when calling as.phylo.hclust():
1645 o dist.dna() returned an error with two identical DNA sequences
1646 (only using the Jukes-Cantor method returned 0): this is fixed.
1651 o The function dist.phylo() has been re-written using a different
1652 algorithm: it is now about four times faster.
1654 o The code of branching.times() has been improved: it is now about
1659 CHANGES IN APE VERSION 1.2-2
1664 o The new function seg.sites() finds the segregating sites in a
1665 sample of DNA sequences.
1670 o A bug introduced in read.tree() and in read.nexus() with version
1673 o A few errors were corrected and a few examples were added in the
1678 CHANGES IN APE VERSION 1.2-1
1683 o plot.phylo() can now draw the edge of the root of a tree if it
1684 has one (see the new option `root.edge', its default is FALSE).
1689 o A bug was fixed in read.nexus(): files with semicolons inside
1690 comment blocks were not read correctly.
1692 o The behaviour of read.tree() and read.nexus() was corrected so
1693 that tree files with badly represented root edges (e.g., with
1694 an extra pair of parentheses, see the help pages for details)
1695 are now correctly represented in the object of class "phylo";
1696 a warning message is now issued.
1700 CHANGES IN APE VERSION 1.2
1705 o plot.phylo() has been completely re-written and offers several
1706 new functionalities. Three types of trees can now be drawn:
1707 phylogram (as previously), cladogram, and unrooted tree; in
1708 all three types the branch lengths can be drawn using the edge
1709 lengths of the phylogeny or not (e.g., if the latter is absent).
1710 The vertical position of the nodes can be adjusted with two
1711 choices (see option `node.pos'). The code has been re-structured,
1712 and two new functions (potentially useful for developpers) are
1713 documented separately: node.depth.edgelength() and node.depth();
1714 see the respective help pages for details.
1716 o The new function zoom() allows to explore very large trees by
1717 focusing on a small portion of it.
1719 o The new function yule() fits by maximum likelihood the Yule model
1720 (birth-only process) to a phylogenetic tree.
1722 o Support for writing DNA sequences in FASTA format has been
1723 introduced in write.dna() (support for reading sequences in
1724 this format was introduced in read.dna() in version 1.1-2).
1725 The function has been completely re-written, fixing some bugs
1726 (see below); the default behaviour is no more to display the
1727 sequences on the standard output. Several options have been
1728 introduced to control the sequence printing in a flexible
1729 way. The help page has been extended.
1731 o A new data set is included: a supertree of bats in NEXUS format.
1736 o In theta.s(), the default of the option `variance' has
1737 been changed to `FALSE' (as was indicated in the help page).
1739 o Several bugs were fixed in the code of all.equal.phylo().
1741 o Several bugs were fixed in write.dna(), particularly this
1742 function did not work with `format = "interleaved"'.
1744 o Various errors were corrected in the help pages.
1749 o The argument names of as.hclust.phylo() have been changed
1750 from "(phy)" to "(x, ...)" to conform to the definition of
1751 the corresponding generic function.
1753 o gamma.stat() has been renamed gammaStat() to avoid confusion
1754 since gamma() is a generic function.
1758 CHANGES IN APE VERSION 1.1-3
1763 o base.freq() previously did not return a value of 0 for
1764 bases absent in the data (e.g., a vector of length 3 was
1765 returned if one base was absent). This is now fixed (a
1766 vector of length 4 is always returned).
1768 o Several bugs were fixed in read.nexus(), including that this
1769 function did not work in this absence of a "TRANSLATE"
1770 command in the NEXUS file, and that the commands were
1775 CHANGES IN APE VERSION 1.1-2
1780 o The Tamura and Nei (1993) model of DNA distance is now implemented
1781 in dist.dna(): five models are now available in this function.
1783 o A new data set is included: a set of 15 sequences of the
1784 cytochrome b mitochondrial gene of the woodmouse (Apodemus
1790 o A bug in read.nexus() was fixed.
1792 o read.dna() previously did not work correctly in most cases.
1793 The function has been completely re-written and its help page
1794 has been considerably extended (see ?read.dna for details).
1795 Underscores (_) in taxon names are no more replaced with
1796 spaces (this behaviour was undocumented).
1798 o A bug was fixed in write.dna().
1802 CHANGES IN APE VERSION 1.1-1
1807 o A bug in read.tree() introduced in APE 1.1 was fixed.
1809 o A bug in compar.gee() resulted in an error when trying to fit
1810 a model with `family = "binomial"'. This is now fixed.
1814 CHANGES IN APE VERSION 1.1
1819 o The Klastorin (1982) method as suggested by Misawa and Tajima
1820 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
1821 on the basis of phylogenetic trees has been implemented (see
1822 the function klastorin()).
1824 o Functions have been added to convert APE's "phylo" objects in
1825 "hclust" cluster objects and vice versa (see the help page of
1826 as.phylo for details).
1828 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
1829 are introduced for the estimation of absolute evolutionary rates
1830 (ratogram) and dated clock-like trees (chronogram) from
1831 phylogenetic trees using the non-parametric rate smoothing approach
1832 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
1834 o A summary method is now provided printing a summary information on a
1835 phylogenetic tree with, for instance, `summary(tree)'.
1837 o The behaviour of read.tree() was changed so that all spaces and
1838 tabulations in tree files are now ignored. Consequently, spaces in tip
1839 labels are no more allowed. Another side effect is that read.nexus()
1840 now does not replace the underscores (_) in tip labels with spaces
1841 (this behaviour was undocumented).
1843 o The function plot.phylo() has a new option (`underscore') which
1844 specifies whether the underscores in tip labels should be written on
1845 the plot as such or replaced with spaces (the default).
1847 o The function birthdeath() now computes 95% confidence intervals of
1848 the estimated parameters using profile likelihood.
1850 o Three new data sets are included: a gene tree estimated from 36
1851 landplant rbcL sequences, a gene tree estimated from 32 opsin
1852 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
1857 o A bug was fixed in dist.gene() where nothing was returned.
1859 o A bug in plot.mst() was fixed.
1861 o A bug in vcv.phylo() resulted in false correlations when the
1862 option `cor = TRUE' was used (now fixed).
1866 CHANGES IN APE VERSION 1.0
1871 o Two new functions, read.dna() and write.dna(), read/write in a file
1872 DNA sequences in interleaved or in sequential format.
1874 o Two new functions, read.nexus() and write.nexus(), read/write trees
1877 o The new function bind.tree() allows to bind two trees together,
1878 possibly handling root edges to give internal branches.
1880 o The new function drop.tip() removes the tips in a phylogenetic tree,
1881 and trims (or not) the corresponding internal branches.
1883 o The new function is.ultrametric() tests if a tree is ultrametric.
1885 o The function plot.phylo() has more functionalities such as drawing the
1886 branches with different colours and/or different widths, showing the
1887 node labels, controling the position and font of the labels, rotating
1888 the labels, and controling the space around the plot.
1890 o The function read.tree() can now read trees with no branch length,
1891 such as "(a,b),c);". Consequently, the element `edge.length' in
1892 objects of class "phylo" is now optional.
1894 o The function write.tree() has a new default behaviour: if the default
1895 for the option `file' is used (i.e. file = ""), then a variable of
1896 mode character containing the tree in Newick format is returned which
1897 can thus be assigned (e.g., tree <- write.tree(phy)).
1899 o The function read.tree() has a new argument `text' which allows
1900 to read the tree in a variable of mode character.
1902 o A new data set is included: the phylogenetic relationships among
1903 the orders of birds from Sibley and Ahlquist (1990).
1907 CHANGES IN APE VERSION 0.2-1
1912 o Several bugs were fixed in the help pages.
1916 CHANGES IN APE VERSION 0.2
1921 o The function write.tree() writes phylogenetic trees (objects of class
1922 "phylo") in an ASCII file using the Newick parenthetic format.
1924 o The function birthdeath() fits a birth-death model to branching times
1925 by maximum likelihood, and estimates the corresponding speciation and
1928 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
1931 o The function is.binary.tree() tests whether a phylogeny is binary.
1933 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
1934 as well as some methods are introduced.
1936 o Several functions, including some generics and methods, for computing
1937 skyline plot estimates (classic and generalized) of effective
1938 population size through time are introduced and replace the function
1939 skyline.plot() in version 0.1.
1941 o Two data sets are now included: the phylogenetic relationships among
1942 the families of birds from Sibley and Ahlquist (1990), and an
1943 estimated clock-like phylogeny of HIV sequences sampled in the
1944 Democratic Republic of Congo.
1947 DEPRECATED & DEFUNCT
1949 o The function skyline.plot() in ape 0.1 has been deprecated and
1950 replaced by more elaborate functions (see above).
1955 o Two important bugs were fixed in plot.phylo(): phylogenies with
1956 multichotomies not at the root or not with only terminal branches,
1957 and phylogenies with a single node (i.e. only terminal branches)
1958 did not plot. These trees should be plotted correctly now.
1960 o Several bugs were fixed in diversi.time() in the computation of
1963 o Various errors were corrected in the help pages.
