1 CHANGES IN APE VERSION 2.7-1
6 o A bug was introduced in read.nexus() in ape 2.7.
8 o image.DNAbin() did not colour correctly the bases if there were
9 '-' and no 'N' in the alignment.
13 CHANGES IN APE VERSION 2.7
18 o There is a new image() method for "DNAbin" objects: it plots DNA
19 alignments in a flexible and efficient way.
21 o Two new functions as.network.phylo and as.igraph.phylo convert
22 trees of class "phylo" into these respective network classes
23 defined in the packages of the same names.
25 o The three new functions clustal, muscle, and tcoffee perform
26 nucleotide sequence alignment by calling the external programs

30 richness.yule.test, and slowinskiguyer.test, implement various
31 tests of diversification shifts using sister-clade comparisons.
33 o base.freq() gains an option 'all' to count all the possible bases
34 including the ambiguous ones (defaults to FALSE).

78 Jinlong Zhang for pointing this bug out).
80 o read.dna(, "fasta") failed if sequences were not all of the same
83 o plot.phylo() did not recycle values of 'font', 'cex' and
84 'tip.color' correctly when type = "fan" or "radial".
86 o plot.phylo() ignored 'label.offset' when type = "radial", "fan", or
87 "unrooted" with lab4ut = "axial" (the placement of tip labels still
88 needs to be improved with lab4ut = "horizontal").
93 o In drop.fossil() the default tol = 0 has been raised to 1e-8.
95 o The help command ?phylo now points to the man page of read.tree()
96 where this class is described. Similarly, ?matching points to the

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

188 with the option model = "Ts" or model = "Tv", respectively.
190 o [node|tip|edge]labels() gain three options with default values to
191 control the aspect of thermometers: horiz = TRUE, width = NULL,
194 o compar.gee() has been improved with the new option 'corStruct' as an
195 alternative to 'phy' to specify the correlation structure, and
196 calculation of the QIC (Pan 2001, Biometrics). The display of the
197 results has also been improved.
199 o read.GenBank() has a new option 'gene.names' to return the name of
200 the gene (FALSE by default).
205 o extract.clade() sometimes shuffled the tip labels.
207 o plot.phylo(type = "unrooted") did not force asp = 1 (thanks to Klaus
210 o dist.dna(model = "logdet") used to divide distances by 4. The
211 documentation has been clarified on the formulae used.
216 o rTraitCont(model = "OU") has an option 'linear = TRUE' to possibly

233 text to be plotted in different fonts.
235 o There are now replacement operators for [, [[, and $ for the class
236 "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They possibly
237 check that the tip labels are the same in all trees.
239 o Objects of class "multiPhylo" can be built with c(): there are
240 methods for the classes "phylo" and "multiPhylo".
242 o The internal functions .compressTipLabel and .uncompressTipLabel are
248 o bind.tree(x, y, where, position = 0) did not work correctly if 'y'
249 was a single-edge tree and 'where' was a tip.

309 'interactive' option to make the operation on a plotted tree.
311 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
312 association links; they are recycled like 'col' (which wasn't before).
317 o rTraitDisc() did not use its 'freq' argument correctly (it was
318 multiplied with the rate matrix column-wise instead of row-wise).
320 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
321 with NA values. Nothing is drawn now like with 'text' or 'pch'.
322 The same bug occurred with the 'pie' option.
324 o A bug was fixed in compar.ou() and the help page was clarified.
326 o bind.tree() has been rewritten fixing several bugs and making it
329 o plot.phylo(type = "p") sometimes failed to colour correctly the
330 vertical lines representing the nodes.
332 o plot.phylo(direction = "l", x.lim = 30) failed to plot the branches
333 in the correct direction though the tip labels were displayed
339 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
340 the sequences are correctly stored (in a list for c, in a matrix
341 for the two other functions).
345 CHANGES IN APE VERSION 2.5
350 o The new function parafit by Pierre Legendre tests for the
351 coevolution between hosts and parasites. It has a companion

372 o The branch length score replaces the geodesic distance in dist.topo.
374 o Three new data sets are included: the gopher-lice data (gopher.D),
375 SO2 air pollution in 41 US cities (lmorigin.ex1, from Sokal &
376 Rohlf 1995), and some host-parasite specificity data
377 (lmorigin.ex2, from Legendre & Desdevises 2009).
382 o add.scale.bar() drew the bar outside the plotting region with the
383 default options with unrooted or radial trees.

405 and "corPhyl" so that it is possible to calculate the var-cov matrix
406 for "transformation models". vcv.phylo() can still be used for trees
407 of class "phylo"; its argument 'cor' has been renamed 'corr'.
412 o bind.tree() failed when 'y' had no root edge.
414 o read.nexus() shuffled tip labels when the trees have no branch
415 lengths and there is a TRANSLATE block.
417 o read.nexus() does not try to translate node labels if there is a
418 translation table in the NEXUS file. See ?read.nexus for a
419 clarification on this behaviour.
421 o plot.multiPhylo() crashed R when plotting a list of trees with
422 compressed tip labels.
424 o write.nexus() did not translate the taxa names when asked for.

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

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

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

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

813 (thanks to Yan Wong for the fix).
815 o drop.tip() failed with some trees (fixed by Yan Wong).
817 o seg.sites() failed with a list.
819 o consensus() failed in some cases. The function has been improved

850 (FALSE by default) as well as its code being improved.
852 o mltt.plot() has now an option 'log' used in the same way
853 than in plot.default().
858 o mltt.plot() failed to display the legend with an unnamed
861 o nodelabels() with pies now correcly uses the argument
862 'cex' to draw symbols of different sizes (which has
863 worked already for thermometers).

870 o The argument 'family' of compar.gee() can now be a function
871 as well as a character string.
873 o read.tree() and read.nexus() now return an unnamed list if
876 o read.nexus() now returns a modified object of class "multiPhylo"
877 when there is a TRANSLATE block in the NEXUS file: the individual
878 trees have no 'tip.label' vector, but the list has a 'TipLabel'
879 attribute. The new methods '$' and '[[' set these elements
880 correctly when extracting trees.
884 CHANGES IN APE VERSION 2.1-1
889 o The new function rmtree generates lists of random trees.

930 as its main argument.
932 o plot.correlogram() and plot.correlogramList() have been
933 improved, and gain several options (see the help page for
934 details). A legend is now plotted by default.
939 o dist.dna() returned some incorrect values with `model = "JC69"'
940 and `pairwise.deletion = TRUE'. This affected only the
941 distances involving sequences with missing values. (Thanks
942 to Bruno Toupance for digging this bug out.)
944 o write.tree() failed with some trees: this is fixed by removing
945 the `multi.line' option (trees are now always printed on a
948 o read.nexus() did not correctly detect trees with multiple root
949 edges (see OTHER CHANGES).

971 o The class c("multi.tree", "phylo") has been renamed
977 o There is now a vignette in ape: see vignette("MoranI", "ape").
982 o as.matching() and as.phylo.matching() do not support branch
985 o correlogram.phylo() and discrete.dist() have been removed.
989 CHANGES IN APE VERSION 2.0-2
994 o The new function matexpo computes the exponential of a square
997 o The new function unique.multi.tree removes duplicate trees from
1000 o yule() has a new option `use.root.edge = FALSE' that specifies
1001 to ignore, by default, the root edge of the tree if it exists.
1006 o which.edge() failed when the index of a single terminal edge was
1009 o In diversi.time(), the values returned for model C were
1012 o A bug was fixed in yule() that affected the calculation of the
1013 likelihood in the presence of ties in the branching times.
1015 o There was a bug in the C function mat_expo4x4 affecting the
1016 calculations of the transition probabilities for models HKY and
1019 o A small bug was fixed in as.matrix.DNAbin (thanks to James
1022 o rtree() did not `shuffle' the tip labels by default, so only a
1023 limited number of labelled topologies could be generated.
1027 CHANGES IN APE VERSION 2.0-1
1032 o The three new functions bionj, fastme.ols, and fastme.bal
1033 perform phylogeny estimation by the BIONJ and fastME methods in
1034 OLS and balanced versions. This is a port to R of previous
1035 previous programs done by Vincent Lefort.
1037 o The new function chronoMPL performs molecular dating with the
1038 mean path lengths method of Britton et al. (2002, Mol. Phyl.
1041 o The new function rotate, contributed by Christoph Heibl, swaps
1042 two clades connected to the same node. It works also with
1043 multichotomous nodes.
1045 o The new `method' as.matrix.DNAbin() may be used to convert
1046 easily DNA sequences stored in a list into a matrix while
1047 keeping the names and the class.
1052 o chronopl() failed when some branch lengths were equal to zero:
1053 an error message is now returned.
1055 o di2multi() failed when there was a series of consecutive edges
1060 CHANGES IN APE VERSION 1.10-2
1065 o plot.phylo() can now plot circular trees: the option is type =
1066 "fan" or type = "f" (to avoid the ambiguity with type = "c").
1068 o prop.part() has a new option `check.labels = FALSE' which allows
1069 to considerably speed-up the calculations of bipartitions. As a
1070 consequence, calculations of bootstrap values with boot.phylo()
1071 should be much faster.
1076 o read.GenBank() did not return correctly the list of species as
1077 from ape 1.10: this is fixed in this version
1079 o Applying as.phylo() on a tree of class "phylo" failed: the
1080 object is now returned unchanged.
1084 CHANGES IN APE VERSION 1.10-1
1089 o The three new functions Ntip, Nnode, and Nedge return, for a
1090 given tree, the number of tips, nodes, or edges, respectively.
1095 o read.nexus() did not set correctly the class of the returned
1096 object when reading multiple trees.
1098 o mllt.plot() failed with objects of class c("multi.tree",
1101 o unroot() did not work correctly in most cases.
1103 o reorder.phylo() made R freeze in some occasions.
1105 o Plotting a tree in pruningwise order failed.
1107 o When plotting an unrooted tree, the tip labels where not all
1108 correctly positioned if the option `cex' was used.
1112 CHANGES IN APE VERSION 1.10
1117 o Five new `method' functions have been introduced to manipulate
1118 DNA sequences in binary format (see below).
1120 o Three new functions have been introduced to convert between the
1121 new binary and the character formats.
1123 o The new function as.alignment converts DNA sequences stored as
1124 single characters into the class "alignment" used by the package
1127 o read.dna() and read.GenBank() have a new argument `as.character'
1128 controlling whether the sequences are returned in binary format
1134 o root() failed when the tree had node labels: this is fixed.
1136 o plot.phylo() did not correctly set the limits on the y-axis with
1137 the default setting: this is fixed.
1139 o dist.dna() returned a wrong result for the LogDet, paralinear,
1140 and BH87 models with `pairwise.deletion = TRUE'.
1145 o DNA sequences are now internally stored in a binary format. See
1146 the document "A Bit-Level Coding Scheme for Nucleotides" for the
1147 details. Most functions analyzing DNA functions have been
1148 modified accordingly and are now much faster (dist.dna is now
1149 ca. 60 times faster).
1153 CHANGES IN APE VERSION 1.9-4
1158 o A bug was fixed in edgelabels().
1160 o as.phylo.hclust() did not work correctly when the object of
1161 class "hclust" has its labels set to NULL: the returned tree has
1162 now its tip labels set to "1", "2", ...
1164 o consensus could fail if some tip labels are a subset of others
1165 (e.g., "a" and "a_1"): this is now fixed.
1167 o mlphylo() failed in most cases if some branch lengths of the
1168 initial tree were greater than one: an error message is now
1171 o mlphylo() failed in most cases when estimating the proportion of
1172 invariants: this is fixed.
1176 CHANGES IN APE VERSION 1.9-3
1181 o The new function edgelabels adds labels on the edge of the tree
1182 in the same way than nodelabels or tiplabels.
1187 o multi2di() did not handle correctly branch lengths with the
1188 default option `random = TRUE': this is now fixed.
1190 o A bug was fixed in nuc.div() when using pairwise deletions.
1192 o A bug occurred in the analysis of bipartitions with large
1193 numbers of large trees, with consequences on prop.part,
1194 prop.clades, and boot.phylo.
1196 o The calculation of the Billera-Holmes-Vogtmann distance in
1197 dist.topo was wrong: this has been fixed.
1201 CHANGES IN APE VERSION 1.9-2
1206 o The new function ladderize reorganizes the internal structure of
1207 a tree to plot them left- or right-ladderized.
1209 o The new function dist.nodes computes the patristic distances
1210 between all nodes, internal and terminal, of a tree. It replaces
1211 the option `full = TRUE' of cophenetic.phylo (see below).
1216 o A bug was fixed in old2new.phylo().
1218 o Some bugs were fixed in chronopl().
1220 o The edge colours were not correctly displayed by plot.phylo
1221 (thank you to Li-San Wang for the fix).
1223 o cophenetic.phylo() failed with multichotomous trees: this is
1229 o read.dna() now returns the sequences in a matrix if they are
1230 aligned (interleaved or sequential format). Sequences in FASTA
1231 format are still returned in a list.
1233 o The option `full' of cophenetic.phylo() has been removed because
1234 it could not be used from the generic.
1237 DEPRECATED & DEFUNCT
1239 o rotate() has been removed; this function did not work correctly
1244 CHANGES IN APE VERSION 1.9-1
1249 o Trees with a single tip were not read correctly in R as the
1250 element `Nnode' was not set: this is fixed.
1252 o unroot() did not set correctly the number of nodes of the
1253 unrooted tree in most cases.
1255 o read.GenBank() failed when fetching very long sequences,
1256 particularly of the BX-series.
1258 o A bug was introduced in read.tree() with ape 1.9: it has been
1263 CHANGES IN APE VERSION 1.9
1268 o There are two new print `methods' for trees of class "phylo" and
1269 lists of trees of class "multi.tree", so that they are now
1270 displayed in a compact and informative way.
1272 o There are two new functions, old2new.phylo and new2old.phylo,
1273 for converting between the old and new coding of the class
1276 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1277 LogDet ("logdet"), and paralinear ("paralin").
1279 o compute.brlen() has been extended: several methods are now
1280 available to compute branch lengths.
1282 o write.dna() can now handle matrices as well as lists.
1287 o cophenetic.phylo() sometimes returned a wrong result with
1288 multichotomous trees: this is fixed.
1290 o rotate() failed when a single tip was specified: the tree is now
1293 o ace() did not return the correct index matrix with custom
1294 models: this is fixed.
1296 o multi2di() did not work correctly when resolving multichotomies
1297 randomly: the topology was always the same, only the arrangement
1298 of clades was randomized: this is fixed. This function now
1299 accepts trees with no branch lengths.
1301 o The output of diversi.gof() was blurred by useless prints when a
1302 user distribution was specified. This has been corrected, and
1303 the help page of this function has been expanded.
1308 o The internal structure of the class "phylo" has been changed:
1309 see the document "Definition of Formats for Coding Phylogenetic
1310 Trees in R" for the details. In addition, the code of most
1311 functions has been improved.
1313 o Several functions have been improved by replacing some R codes
1314 by C codes: pic, plot.phylo, and reorder.phylo.
1316 o There is now a citation information: see citation("ape") in R.
1318 o write.tree() now does not add extra 0's to branch lengths so
1319 that 1.23 is printed "1.23" by default, not "1.2300000000".
1321 o The syntax of bind.tree() has been simplified. This function now
1322 accepts trees with no branch lengths, and handles correctly node
1325 o The option `as.numeric' of mrca() has been removed.
1327 o The unused options `format' and `rooted' of read.tree() have
1330 o The unused option `format' of write.tree() has been removed.
1332 o The use of node.depth() has been simplified.
1336 CHANGES IN APE VERSION 1.8-5
1341 o Two new functions read.nexus.data() and write.nexus.data(),
1342 contributed by Johan Nylander, allow to read and write molecular
1343 sequences in NEXUS files.
1345 o The new function reorder.phylo() reorders the internal structure
1346 of a tree of class "phylo". It is used as the generic, e.g.,
1349 o read.tree() and read.nexus() can now read trees with a single
1352 o The new data set `cynipids' supplies a set of protein sequences
1358 o The code of all.equal.phylo() has been completely rewritten
1359 (thanks to Benoît Durand) which fixes several bugs.
1361 o read.tree() and read.nexus() now checks the labels of the tree
1362 to remove or substitute any characters that are illegal in the
1363 Newick format (parentheses, etc.)
1365 o A negative P-value could be returned by mantel.test(): this is
1370 CHANGES IN APE VERSION 1.8-4
1375 o The new function sh.test() computes the Shimodaira-
1378 o The new function collapse.singles() removes the nodes with a
1379 single descendant from a tree.
1381 o plot.phylo() has a new argument `tip.color' to specify the
1382 colours of the tips.
1384 o mlphylo() has now an option `quiet' to control the display of
1385 the progress of the analysis (the default is FALSE).
1390 o read.dna() did not read correctly sequences in sequential format
1391 with leading alignment gaps "-": this is fixed.
1393 o ace() returned a list with no class so that the generic
1394 functions (anova, logLik, ...) could not be used directly. This
1395 is fixed as ace() now returns an object of class "ace".
1397 o anova.ace() had a small bug when computing the number of degrees
1398 of freedom: this is fixed.
1400 o mlphylo() did not work when the sequences were in a matrix or
1401 a data frame: this is fixed.
1403 o rtree() did not work correctly when trying to simulate an
1404 unrooted tree with two tips: an error message is now issued.
1409 o The algorithm of rtree() has been changed: it is now about 40,
1410 100, and 130 times faster for 10, 100, and 1000 tips,
1415 CHANGES IN APE VERSION 1.8-3
1420 o There are four new `method' functions to be used with the
1421 results of ace(): logLik(), deviance(), AIC(), and anova().
1423 o The plot method of phymltest has two new arguments: `main' to
1424 change the title, and `col' to control the colour of the
1425 segments showing the AIC values.
1427 o ace() has a new argument `ip' that gives the initial values used
1428 in the ML estimation with discrete characters (see the examples
1429 in ?ace). This function now returns a matrix giving the indices
1430 of the estimated rates when analysing discrete characters.
1432 o nodelabels() and tiplabels() have a new argument `pie' to
1433 represent proportions, with any number of categories, as
1434 piecharts. The use of the option `thermo' has been improved:
1435 there is now no limitation on the number of categories.
1440 o mlphylo() did not work with more than two partitions: this is
1443 o root() failed if the proposed outgroup was already an outgroup
1444 in the tree: this is fixed.
1446 o The `col' argument in nodelabels() and tiplabels() was not
1447 correctly passed when `text' was used: this is fixed.
1449 o Two bugs were fixed in mlphylo(): parameters were not always
1450 correctly output, and the estimation failed in some cases.
1452 o plot.phylo() was stuck when given a tree with a single tip: this
1453 is fixed and a message error is now returned.
1455 o An error was corrected in the help page of gammaStat regarding
1456 the calculation of P-values.
1458 o Using gls() could crash R when the number of species in the tree
1459 and in the variables were different: this is fixed.
1463 CHANGES IN APE VERSION 1.8-2
1468 o The new function mlphylo() fits a phylogenetic tree by maximum
1469 likelihood from DNA sequences. Its companion function DNAmodel()
1470 is used to define the substitution model which may include
1471 partitioning. There are methods for logLik(), deviance(), and
1472 AIC(), and the summary() method has been extended to display in
1473 a friendly way the results of this model fitting. Currently, the
1474 functionality is limited to estimating the substitution and
1475 associated parameters and computing the likelihood.
1477 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1478 tests for single effects in GEE-based comparative method. A
1479 warning message is printed if there is not enough degrees of
1485 o An error message was sometimes issued by plot.multi.tree(),
1486 though with no consequence.
1490 CHANGES IN APE VERSION 1.8-1
1495 o There is a new plot method for lists of trees (objects of class
1496 "multi.tree"): it calls plot.phylo() internally and is
1497 documented on the same help page.
1502 o A bug was fixed in the C code that analyzes bipartitions: this
1503 has impact on several functions like prop.part, prop.clades,
1504 boot.phylo, or consensus.
1506 o root() did not work correctly when the specified outgroup had
1507 more than one element: this is fixed.
1509 o dist.dna() sometimes returned a warning inappropriately: this
1512 o If the distance object given to nj() had no rownames, nj()
1513 returned a tree with no tip labels: it now returns tips labelled
1514 "1", "2", ..., corresponding to the row numbers.
1519 o nj() has been slightly changed so that tips with a zero distance
1520 are first aggregated with zero-lengthed branches; the usual NJ
1521 procedure is then performed on a distance matrix without 0's.
1525 CHANGES IN APE VERSION 1.8
1530 o The new function chronopl() estimates dates using the penalized
1531 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1533 o The new function consensus() calculates the consensus tree of a
1536 o The new function evolve.phylo() simulates the evolution of
1537 continuous characters along a phylogeny under a Brownian model.
1539 o The new plot method for objects of class "ancestral" displays a
1540 tree together with ancestral values, as returned by the above
1543 o The new function as.phylo.formula() returns a phylogeny from a
1544 set of nested taxonomic variables given as a formula.
1546 o The new function read.caic() reads trees in CAIC format.
1548 o The new function tiplabels() allows to add labels to the tips
1549 of a tree using text or plotting symbols in a flexible way.
1551 o The new function unroot() unroots a phylogeny.
1553 o multi2di() has a new option, `random', which specifies whether
1554 to resolve the multichotomies randomly (the default) or not.
1556 o prop.part() now returns an object of class "prop.part" for which
1557 there are print (to display a partition in a more friendly way)
1558 and summary (to extract the numbers) methods.
1560 o plot.phylo() has a new option, `show.tip.label', specifying
1561 whether to print the labels of the tips. The default is TRUE.
1563 o The code of nj() has been replaced by a faster C code: it is now
1564 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1567 o write.nexus() now writes whether a tree is rooted or not.
1572 o Two bugs have been fixed in root(): unrooted trees are now
1573 handled corretly, and node labels are now output normally.
1575 o A bug was fixed in phymltest(): the executable couldn't be found
1578 o Three bug have been fixed in ace(): computing the likelihood of
1579 ancestral states of discrete characters failed, custom models
1580 did not work, and the function failed with a null gradient (a
1581 warning message is now returned; this latter bug was also
1582 present in yule.cov() as well and is now fixed).
1584 o pic() hanged out when missing data were present: a message error
1587 o A small bug was fixed in dist.dna() where the gamma correction
1588 was not always correctly dispatched.
1590 o plot.phylo() plotted correctly the root edge only when the tree
1591 was plotted rightwards: this works now for all directions.
1596 o dist.taxo() has been renamed as weight.taxo().
1598 o dist.phylo() has been replaced by the method cophenetic.phylo().
1600 o Various error and warning messages have been improved.
1604 CHANGES IN APE VERSION 1.7
1607 o The new function ace() estimates ancestral character states for
1608 continuous characters (with ML, GLS, and contrasts methods), and
1609 discrete characters (with ML only) for any number of states.
1611 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1612 of directional evolution for continuous characters. The user
1613 specifies the node(s) of the tree where the character optimum
1616 o The new function is.rooted() tests whether a tree (of class
1619 o The new function rcoal() generates random ultrametric trees with
1620 the possibility to specify the function that generates the
1621 inter-nodes distances.
1623 o The new function mrca() gives for all pairs of tips in a tree
1624 (and optionally nodes too) the most recent common ancestor.
1626 o nodelabels() has a new option `thermo' to plot proportions (up
1627 to three classes) on the nodes of a tree.
1629 o rtree() has been improved: it can now generate rooted or
1630 unrooted trees, and the mathematical function that generates the
1631 branch lengths may be specified by the user. The tip labels may
1632 be given directly in the call to rtree. The limit cases (n = 2,
1633 3) are now handled correctly.
1635 o dist.topo() has a new argument `method' with two choices: "PH85"
1636 for Penny and Henny's method (already available before and now
1637 the default), and "BHV01" for the geometric distance by Billera
1638 et al. (2001, Adv. Appl. Math. 27:733).
1640 o write.tree() has a new option, `digits', which specifies the
1641 number of digits to be printed in the Newick tree. By default
1642 digits = 10. The numbers are now always printed in decimal form
1643 (i.e., 1.0e-1 is now avoided).
1645 o dist.dna() can now compute the raw distances between pairs of
1646 DNA sequences by specifying model = "raw".
1648 o dist.phylo() has a new option `full' to possibly compute the
1649 distances among all tips and nodes of the tree. The default if
1655 o Several bugs were fixed in all.equal.phylo().
1657 o dist.dna() did not handle correctly gaps ("-") in alignments:
1658 they are now considered as missing data.
1660 o rotate() did not work if the tips were not ordered: this is
1663 o mantel.test() returned NA in some special cases: this is fixed
1664 and the function has been improved and is now faster.
1666 o A bug was fixed in diversi.gof() where the calculation of A² was
1669 o cherry() did not work correctly under some OSs (mainly Linux):
1672 o is.binary.tree() has been modified so that it works with both
1673 rooted and unrooted trees.
1675 o The documentation of theta.s() was not correct: this has been
1678 o plot.mst() did not work correctly: this is fixed.
1682 CHANGES IN APE VERSION 1.6
1687 o The new function dist.topo() computes the topological distances
1690 o The new function boot.phylo() performs a bootstrap analysis on
1691 phylogeny estimation.
1693 o The new functions prop.part() and prop.clades() analyse
1694 bipartitions from a series of trees.
1699 o read.GenBank() now uses the EFetch utility of NCBI instead of
1700 the usual Web interface: it is now much faster (e.g., 12 times
1701 faster to retrieve 8 sequences, 37 times for 60 sequences).
1706 o Several bugs were fixed in read.dna().
1708 o Several bugs were fixed in diversi.time().
1710 o is.binary.tree() did not work correctly if the tree has no edge
1711 lengths: this is fixed.
1713 o drop.tip() did not correctly propagated the `node.label' of a
1714 tree: this is fixed.
1718 CHANGES IN APE VERSION 1.5
1723 o Two new functions, as.matching.phylo() and as.phylo.matching(),
1724 convert objects between the classes "phylo" and "matching". The
1725 latter implements the representation of binary trees introduced by
1726 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
1727 as.matching() has been introduced as well.
1729 o Two new functions, multi2di() and di2multi(), allow to resolve
1730 and collapse multichotomies with branches of length zero.
1732 o The new function nuc.div() computes the nucleotide diversity
1733 from a sample a DNA sequences.
1735 o dist.dna() has been completely rewritten with a much faster
1736 (particularly for large data sets) C code. Eight models are
1737 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
1738 option `method' has been renamed `model'). Computation of variance
1739 is available for all models. A gamma-correction is possible for
1740 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
1741 to remove sites with missing data on a pairwise basis. The option
1742 `GCcontent' has been removed.
1744 o read.GenBank() has a new option (species.names) which specifies
1745 whether to return the species names of the organisms in addition
1746 to the accession numbers of the sequences (this is the default
1749 o write.nexus() can now write several trees in the same NEXUS file.
1751 o drop.tip() has a new option `root.edge' that allows to specify the
1752 new root edge if internal branches are trimmed.
1757 o as.phylo.hclust() failed if some labels had parentheses: this
1760 o Several bugs were fixed in all.equal.phylo(). This function now
1761 returns the logical TRUE if the trees are identical but with
1762 different representations (a report was printed previously).
1764 o read.GenBank() did not correctly handle ambiguous base codes:
1770 o birthdeath() now returns an object of class "birthdeath" for
1771 which there is a print method.
1775 CHANGES IN APE VERSION 1.4
1780 o The new function nj() performs phylogeny estimation with the
1781 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
1784 o The new function which.edge() identifies the edges of a tree
1785 that belong to a group specified as a set of tips.
1787 o The new function as.phylo.phylog() converts an object of class
1788 "phylog" (from the package ade4) into an object of class
1791 o The new function axisPhylo() draws axes on the side of a
1794 o The new function howmanytrees() calculates the number of trees
1795 in different cases and giving a number of tips.
1797 o write.tree() has a new option `multi.line' (TRUE by default) to
1798 write a Newick tree on several lines rather than on a single
1801 o The functionalities of zoom() have been extended. Several
1802 subtrees can be visualized at the same time, and they are marked
1803 on the main tree with colors. The context of the subtrees can be
1804 marked with the option `subtree' (see below).
1806 o drop.tip() has a new option `subtree' (FALSE by default) which
1807 specifies whether to output in the tree how many tips have been
1810 o The arguments of add.scale.bar() have been redefined and have
1811 now default values (see ?add.scale.bar for details). This
1812 function now works even if the plotted tree has no edge length.
1814 o plot.phylo() can now plot radial trees, but this does not take
1815 edge lengths into account.
1817 o In plot.phylo() with `type = "phylogram"', if the values of
1818 `edge.color' and `edge.width' are identical for sister-branches,
1819 they are propagated to the vertical line that link them.
1824 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
1825 crashing. This is fixed.
1827 o In plot.phylo(), the options `edge.color' and `edge.width' are
1828 now properly recycled; their default values are now "black" and
1831 o A bug has been fixed in write.nexus().
1836 o The function node.depth.edgelength() has been removed and
1837 replaced by a C code.
1841 CHANGES IN APE VERSION 1.3-1
1846 o The new function nodelabels() allows to add labels to the nodes
1847 of a tree using text or plotting symbols in a flexible way.
1849 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
1850 numeric values specifying the lower and upper limits on the x-
1851 and y-axes. This allows to leave some space on any side of the
1852 tree. If a single value is given, this is taken as the upper
1857 CHANGES IN APE VERSION 1.3
1862 o The new function phymltest() calls the software PHYML and fits
1863 28 models of DNA sequence evolution. There are a print method to
1864 display likelihood and AIC values, a summary method to compute
1865 the hierarchical likelihood ratio tests, and a plot method to
1866 display graphically the AIC values of each model.
1868 o The new function yule.cov() fits the Yule model with covariates,
1869 a model where the speciation rate is affected by several species
1870 traits through a generalized linear model. The parameters are
1871 estimated by maximum likelihood.
1873 o Three new functions, corBrownian(), corGrafen(), and
1874 corMartins(), compute the expected correlation structures among
1875 species given a phylogeny under different models of evolution.
1876 These can be used for GLS comparative phylogenetic methods (see
1877 the examples). There are coef() and corMatrix() methods and an
1878 Initialize.corPhyl() function associated.
1880 o The new function compar.cheverud() implements Cheverud et al.'s
1881 (1985; Evolution 39:1335) phylogenetic comparative method.
1883 o The new function varcomp() estimates variance components; it has
1886 o Two new functions, panel.superpose.correlogram() and
1887 plot.correlogramList(), allow to plot several phylogenetic
1890 o The new function node.leafnumber() computes the number of leaves
1891 of a subtree defined by a particular node.
1893 o The new function node.sons() gets all tags of son nodes from a
1896 o The new function compute.brlen() computes the branch lengths of
1897 a tree according to a specified method.
1899 o plot.phylo() has three new options: "cex" controls the size of
1900 the (tip and node) labels (thus it is no more needed to change
1901 the global graphical parameter), "direction" which allows to
1902 plot the tree rightwards, leftwards, upwards, or downwards, and
1903 "y.lim" which sets the upper limit on the y-axis.
1908 o Some functions which try to match tip labels and names of
1909 additional data (e.g. vector) are likely to fail if there are
1910 typing or syntax errors. If both series of names do not perfectly
1911 match, they are ignored and a warning message is now issued.
1912 These functions are bd.ext, compar.gee, pic. Their help pages
1913 have been clarified on this point.
1917 CHANGES IN APE VERSION 1.2-7
1922 o The new function root() reroots a phylogenetic tree with respect
1923 to a specified outgroup.
1925 o The new function rotate() rotates an internal branch of a tree.
1927 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
1928 trees) controls the display of the tip labels in unrooted trees.
1929 This display has been greatly improved: the tip labels are now not
1930 expected to overlap with the tree (particularly if lab4ut =
1931 "axial"). In all cases, combining appropriate values of "lab4ut"
1932 and the font size (via "par(cex = )") should result in readable
1933 unrooted trees. See ?plot.phylo for some examples.
1935 o In drop.tip(), the argument `tip' can now be numeric or character.
1940 o drop.tip() did not work correctly with trees with no branch
1941 lengths: this is fixed.
1943 o A bug in plot.phylo(..., type = "unrooted") made some trees being
1944 plotted with some line crossings: this is now fixed.
1948 CHANGES IN APE VERSION 1.2-6
1953 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
1954 correlogram.phylo, dist.taxo, plot.correlogram) have been added
1955 to implement comparative methods with an autocorrelation approach.
1957 o A new data set describing some life history traits of Carnivores
1963 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
1968 o When plotting a tree with plot.phylo(), the new default of the
1969 option `label.offset' is now 0, so the labels are always visible.
1973 CHANGES IN APE VERSION 1.2-5
1978 o The new function bd.ext() fits a birth-death model with combined
1979 phylogenetic and taxonomic data, and estimates the corresponding
1980 speciation and extinction rates.
1985 o The package gee is no more required by ape but only suggested
1986 since only the function compar.gee() calls gee.
1990 CHANGES IN APE VERSION 1.2-4
1995 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
1996 and lines.popsize) implementing a new approach for inferring the
1997 demographic history from genealogies using a reversible jump
1998 MCMC have been introduced.
2000 o The unit of time in the skyline plot and in the new plots can
2001 now be chosen to be actual years, rather than substitutions.
2005 CHANGES IN APE VERSION 1.2-3
2010 o The new function rtree() generates a random binary tree with or
2011 without branch lengths.
2013 o Two new functions for drawing lineages-through-time (LTT) plots
2014 are provided: ltt.lines() adds a LTT curve to an existing plot,
2015 and mltt.plot() does a multiple LTT plot giving several trees as
2016 arguments (see `?ltt.plot' for details).
2021 o Some taxon names made R crashing when calling as.phylo.hclust():
2024 o dist.dna() returned an error with two identical DNA sequences
2025 (only using the Jukes-Cantor method returned 0): this is fixed.
2030 o The function dist.phylo() has been re-written using a different
2031 algorithm: it is now about four times faster.
2033 o The code of branching.times() has been improved: it is now about
2038 CHANGES IN APE VERSION 1.2-2
2043 o The new function seg.sites() finds the segregating sites in a
2044 sample of DNA sequences.
2049 o A bug introduced in read.tree() and in read.nexus() with version
2052 o A few errors were corrected and a few examples were added in the
2057 CHANGES IN APE VERSION 1.2-1
2062 o plot.phylo() can now draw the edge of the root of a tree if it
2063 has one (see the new option `root.edge', its default is FALSE).
2068 o A bug was fixed in read.nexus(): files with semicolons inside
2069 comment blocks were not read correctly.
2071 o The behaviour of read.tree() and read.nexus() was corrected so
2072 that tree files with badly represented root edges (e.g., with
2073 an extra pair of parentheses, see the help pages for details)
2074 are now correctly represented in the object of class "phylo";
2075 a warning message is now issued.
2079 CHANGES IN APE VERSION 1.2
2084 o plot.phylo() has been completely re-written and offers several
2085 new functionalities. Three types of trees can now be drawn:
2086 phylogram (as previously), cladogram, and unrooted tree; in
2087 all three types the branch lengths can be drawn using the edge
2088 lengths of the phylogeny or not (e.g., if the latter is absent).
2089 The vertical position of the nodes can be adjusted with two
2090 choices (see option `node.pos'). The code has been re-structured,
2091 and two new functions (potentially useful for developpers) are
2092 documented separately: node.depth.edgelength() and node.depth();
2093 see the respective help pages for details.
2095 o The new function zoom() allows to explore very large trees by
2096 focusing on a small portion of it.
2098 o The new function yule() fits by maximum likelihood the Yule model
2099 (birth-only process) to a phylogenetic tree.
2101 o Support for writing DNA sequences in FASTA format has been
2102 introduced in write.dna() (support for reading sequences in
2103 this format was introduced in read.dna() in version 1.1-2).
2104 The function has been completely re-written, fixing some bugs
2105 (see below); the default behaviour is no more to display the
2106 sequences on the standard output. Several options have been
2107 introduced to control the sequence printing in a flexible
2108 way. The help page has been extended.
2110 o A new data set is included: a supertree of bats in NEXUS format.
2115 o In theta.s(), the default of the option `variance' has
2116 been changed to `FALSE' (as was indicated in the help page).
2118 o Several bugs were fixed in the code of all.equal.phylo().
2120 o Several bugs were fixed in write.dna(), particularly this
2121 function did not work with `format = "interleaved"'.
2123 o Various errors were corrected in the help pages.
2128 o The argument names of as.hclust.phylo() have been changed
2129 from "(phy)" to "(x, ...)" to conform to the definition of
2130 the corresponding generic function.
2132 o gamma.stat() has been renamed gammaStat() to avoid confusion
2133 since gamma() is a generic function.
2137 CHANGES IN APE VERSION 1.1-3
2142 o base.freq() previously did not return a value of 0 for
2143 bases absent in the data (e.g., a vector of length 3 was
2144 returned if one base was absent). This is now fixed (a
2145 vector of length 4 is always returned).
2147 o Several bugs were fixed in read.nexus(), including that this
2148 function did not work in this absence of a "TRANSLATE"
2149 command in the NEXUS file, and that the commands were
2154 CHANGES IN APE VERSION 1.1-2
2159 o The Tamura and Nei (1993) model of DNA distance is now implemented
2160 in dist.dna(): five models are now available in this function.
2162 o A new data set is included: a set of 15 sequences of the
2163 cytochrome b mitochondrial gene of the woodmouse (Apodemus
2169 o A bug in read.nexus() was fixed.
2171 o read.dna() previously did not work correctly in most cases.
2172 The function has been completely re-written and its help page
2173 has been considerably extended (see ?read.dna for details).
2174 Underscores (_) in taxon names are no more replaced with
2175 spaces (this behaviour was undocumented).
2177 o A bug was fixed in write.dna().
2181 CHANGES IN APE VERSION 1.1-1
2186 o A bug in read.tree() introduced in APE 1.1 was fixed.
2188 o A bug in compar.gee() resulted in an error when trying to fit
2189 a model with `family = "binomial"'. This is now fixed.
2193 CHANGES IN APE VERSION 1.1
2198 o The Klastorin (1982) method as suggested by Misawa and Tajima
2199 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
2200 on the basis of phylogenetic trees has been implemented (see
2201 the function klastorin()).
2203 o Functions have been added to convert APE's "phylo" objects in
2204 "hclust" cluster objects and vice versa (see the help page of
2205 as.phylo for details).
2207 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
2208 are introduced for the estimation of absolute evolutionary rates
2209 (ratogram) and dated clock-like trees (chronogram) from
2210 phylogenetic trees using the non-parametric rate smoothing approach
2211 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
2213 o A summary method is now provided printing a summary information on a
2214 phylogenetic tree with, for instance, `summary(tree)'.
2216 o The behaviour of read.tree() was changed so that all spaces and
2217 tabulations in tree files are now ignored. Consequently, spaces in tip
2218 labels are no more allowed. Another side effect is that read.nexus()
2219 now does not replace the underscores (_) in tip labels with spaces
2220 (this behaviour was undocumented).
2222 o The function plot.phylo() has a new option (`underscore') which
2223 specifies whether the underscores in tip labels should be written on
2224 the plot as such or replaced with spaces (the default).
2226 o The function birthdeath() now computes 95% confidence intervals of
2227 the estimated parameters using profile likelihood.
2229 o Three new data sets are included: a gene tree estimated from 36
2230 landplant rbcL sequences, a gene tree estimated from 32 opsin
2231 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
2236 o A bug was fixed in dist.gene() where nothing was returned.
2238 o A bug in plot.mst() was fixed.
2240 o A bug in vcv.phylo() resulted in false correlations when the
2241 option `cor = TRUE' was used (now fixed).
2245 CHANGES IN APE VERSION 1.0
2250 o Two new functions, read.dna() and write.dna(), read/write in a file
2251 DNA sequences in interleaved or in sequential format.
2253 o Two new functions, read.nexus() and write.nexus(), read/write trees
2256 o The new function bind.tree() allows to bind two trees together,
2257 possibly handling root edges to give internal branches.
2259 o The new function drop.tip() removes the tips in a phylogenetic tree,
2260 and trims (or not) the corresponding internal branches.
2262 o The new function is.ultrametric() tests if a tree is ultrametric.
2264 o The function plot.phylo() has more functionalities such as drawing the
2265 branches with different colours and/or different widths, showing the
2266 node labels, controling the position and font of the labels, rotating
2267 the labels, and controling the space around the plot.
2269 o The function read.tree() can now read trees with no branch length,
2270 such as "(a,b),c);". Consequently, the element `edge.length' in
2271 objects of class "phylo" is now optional.
2273 o The function write.tree() has a new default behaviour: if the default
2274 for the option `file' is used (i.e. file = ""), then a variable of
2275 mode character containing the tree in Newick format is returned which
2276 can thus be assigned (e.g., tree <- write.tree(phy)).
2278 o The function read.tree() has a new argument `text' which allows
2279 to read the tree in a variable of mode character.
2281 o A new data set is included: the phylogenetic relationships among
2282 the orders of birds from Sibley and Ahlquist (1990).
2286 CHANGES IN APE VERSION 0.2-1
2291 o Several bugs were fixed in the help pages.
2295 CHANGES IN APE VERSION 0.2
2300 o The function write.tree() writes phylogenetic trees (objects of class
2301 "phylo") in an ASCII file using the Newick parenthetic format.
2303 o The function birthdeath() fits a birth-death model to branching times
2304 by maximum likelihood, and estimates the corresponding speciation and
2307 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2310 o The function is.binary.tree() tests whether a phylogeny is binary.
2312 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2313 as well as some methods are introduced.
2315 o Several functions, including some generics and methods, for computing
2316 skyline plot estimates (classic and generalized) of effective
2317 population size through time are introduced and replace the function
2318 skyline.plot() in version 0.1.
2320 o Two data sets are now included: the phylogenetic relationships among
2321 the families of birds from Sibley and Ahlquist (1990), and an
2322 estimated clock-like phylogeny of HIV sequences sampled in the
2323 Democratic Republic of Congo.
2326 DEPRECATED & DEFUNCT
2328 o The function skyline.plot() in ape 0.1 has been deprecated and
2329 replaced by more elaborate functions (see above).
2334 o Two important bugs were fixed in plot.phylo(): phylogenies with
2335 multichotomies not at the root or not with only terminal branches,
2336 and phylogenies with a single node (i.e. only terminal branches)
2337 did not plot. These trees should be plotted correctly now.
2339 o Several bugs were fixed in diversi.time() in the computation of
2342 o Various errors were corrected in the help pages.
