41 'interactive' option to make the operation on a plotted tree.
43 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
44 association links; they are recycled like 'col' (which wasn't before).
49 o rTraitDisc() did not use its 'freq' argument correctly (it was
50 multiplied with the rate matrix column-wise instead of row-wise).
52 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
53 with NA values. Nothing is drawn now like with 'text' or 'pch'.
54 The same bug occurred with the 'pie' option.
56 o A bug was fixed in compar.ou() and the help page was clarified.
58 o bind.tree() has been rewritten fixing several bugs and making it
61 o plot.phylo(type = "p") sometimes failed to colour correctly the
62 vertical lines representing the nodes.
64 o plot.phylo(direction = "l", x.lim = 30) failed to plot the branches
65 in the correct direction though the tip labels were displayed

72 the sequences are correctly stored (in a list for c, in a matrix
73 for the two other functions).
77 CHANGES IN APE VERSION 2.5
82 o The new function parafit by Pierre Legendre tests for the
83 coevolution between hosts and parasites. It has a companion

88 regression through the origin with testing by permutation.
90 o The new functions rTraitCont and rTraitDisc simulate continuous and
91 discrete traits under a wide range of evolutionary models.

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

136 o vcv() is a new generic function with methods for the classes "phylo"
137 and "corPhyl" so that it is possible to calculate the var-cov matrix
138 for "transformation models". vcv.phylo() can still be used for trees
139 of class "phylo"; its argument 'cor' has been renamed 'corr'.
144 o bind.tree() failed when 'y' had no root edge.
146 o read.nexus() shuffled tip labels when the trees have no branch
147 lengths and there is a TRANSLATE block.
149 o read.nexus() does not try to translate node labels if there is a
150 translation table in the NEXUS file. See ?read.nexus for a
151 clarification on this behaviour.
153 o plot.multiPhylo() crashed R when plotting a list of trees with
154 compressed tip labels.
156 o write.nexus() did not translate the taxa names when asked for.
158 o plot.phylo(type = "fan") did not rotate the tip labels correctly
159 when the tree has branch lengths.

164 o nj() crashed with NA/NaN in the distance matrix: an error in now
169 CHANGES IN APE VERSION 2.4
174 o base.freq() has a new option 'freq' to return the counts; the
175 default is still to return the proportions.
180 o seg.sites() did not handle ambiguous nucleotides correctly: they
183 o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
184 the tree: the argument is now ignored.

193 warning (it returned an error previously).
195 o The way lines representing nodes are coloured in phylograms has
196 been modified (as well as their widths and types) following some
197 users' request; this is only for dichotomous nodes.
199 o The argument 'adj' in [node][tip][edge]labels() now works when
200 using 'pie' or 'thermo'.
202 o A more informative message error is now returned by dist.dna() when

257 o extract.clade() sometimes included too many edges.
259 o vcv.phylo() did not work correctly when the tree is in
262 o nj() did not handle correctly distance matrices with many 0's.

264 faster with n = 100, 500, 1000, respectively.
268 CHANGES IN APE VERSION 2.3-1
273 o The new function is.monophyletic tests the monophyly of a group.

281 to be treated as (un)rooted.
286 o dist.gene() failed on most occasions with the default
287 pairwise.deletion = FALSE.

393 specifying model="N".
398 o chronopl() did not work with CV = TRUE.
400 o read.nexus() did not work correctly in some situations (trees on
401 multiple lines with different numbers of lines and/or with

405 the number of lineages with non-binary trees.
410 o ape has now a namespace.
412 o drop.tip() has been improved: it should be much faster and work
413 better in some cases (e.g., see the example in ?zoom).

422 o dist.gene() has been substantially improved and gains an option
425 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
431 o prop.part() failed with a single tree with the default option
432 'check.labels = TRUE'.
434 o summary.DNAbin() failed to display correctly the summary of
435 sequence lengths with lists of sequences of 10,000 bases or more
436 (because summary.default uses 4 significant digits by default).
438 o read.nexus() failed to read a file with a single tree with line
439 breaks in the Newick string.
441 o del.gaps() returned a list of empty sequences when there were no

453 o The data sets bird.orders and bird.families are now stored as
454 Newick strings; i.e., the command data(bird.orders) calls
459 CHANGES IN APE VERSION 2.2-1
464 o The new function makeLabel() helps to modify labels of trees,
465 lists of trees, or DNA sequences, with several utilities to
466 truncate and/or make them unique, substituting some
467 characters, and so on.
469 o The new function del.gaps() removes insertion gaps ("-") in a
470 set of DNA sequences.

510 CHANGES IN APE VERSION 2.2
515 o Four new functions have been written by Damien de Vienne for the
516 graphical exploration of large trees (cophyloplot, subtrees,
517 subtreeplot), and to return the graphical coordinates of tree

541 o Drawing the tip labels sometimes failed when plotting circular
544 o zoom() failed when tip labels were used instead of their numbers
545 (thanks to Yan Wong for the fix).
547 o drop.tip() failed with some trees (fixed by Yan Wong).
549 o seg.sites() failed with a list.
551 o consensus() failed in some cases. The function has been improved

585 than in plot.default().
590 o mltt.plot() failed to display the legend with an unnamed
593 o nodelabels() with pies now correcly uses the argument
594 'cex' to draw symbols of different sizes (which has
595 worked already for thermometers).
597 o read.nexus() generally failed to read very big files.
602 o The argument 'family' of compar.gee() can now be a function
603 as well as a character string.
605 o read.tree() and read.nexus() now return an unnamed list if
608 o read.nexus() now returns a modified object of class "multiPhylo"
609 when there is a TRANSLATE block in the NEXUS file: the individual
610 trees have no 'tip.label' vector, but the list has a 'TipLabel'
611 attribute. The new methods '$' and '[[' set these elements
612 correctly when extracting trees.
616 CHANGES IN APE VERSION 2.1-1
621 o The new function rmtree generates lists of random trees.
623 o rcoal() now generates a genuine coalescent tree by default

635 o The internal codes of bionj(), fastme.bal(), and fastme.ols()
636 have been improved so that they are stabler and faster.

662 as its main argument.
664 o plot.correlogram() and plot.correlogramList() have been
665 improved, and gain several options (see the help page for
666 details). A legend is now plotted by default.
671 o dist.dna() returned some incorrect values with `model = "JC69"'
672 and `pairwise.deletion = TRUE'. This affected only the
673 distances involving sequences with missing values. (Thanks
674 to Bruno Toupance for digging this bug out.)
676 o write.tree() failed with some trees: this is fixed by removing
677 the `multi.line' option (trees are now always printed on a
680 o read.nexus() did not correctly detect trees with multiple root
681 edges (see OTHER CHANGES).
686 o The code of mlphylo() has been almost entirely rewritten, and

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

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

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

778 easily DNA sequences stored in a list into a matrix while
779 keeping the names and the class.
784 o chronopl() failed when some branch lengths were equal to zero:
785 an error message is now returned.
787 o di2multi() failed when there was a series of consecutive edges
792 CHANGES IN APE VERSION 1.10-2
797 o plot.phylo() can now plot circular trees: the option is type =
798 "fan" or type = "f" (to avoid the ambiguity with type = "c").
800 o prop.part() has a new option `check.labels = FALSE' which allows
801 to considerably speed-up the calculations of bipartitions. As a
802 consequence, calculations of bootstrap values with boot.phylo()
803 should be much faster.
808 o read.GenBank() did not return correctly the list of species as
809 from ape 1.10: this is fixed in this version
811 o Applying as.phylo() on a tree of class "phylo" failed: the

850 DNA sequences in binary format (see below).
852 o Three new functions have been introduced to convert between the
853 new binary and the character formats.
855 o The new function as.alignment converts DNA sequences stored as
856 single characters into the class "alignment" used by the package
859 o read.dna() and read.GenBank() have a new argument `as.character'
860 controlling whether the sequences are returned in binary format
866 o root() failed when the tree had node labels: this is fixed.

869 the default setting: this is fixed.
871 o dist.dna() returned a wrong result for the LogDet, paralinear,
872 and BH87 models with `pairwise.deletion = TRUE'.
877 o DNA sequences are now internally stored in a binary format. See
878 the document "A Bit-Level Coding Scheme for Nucleotides" for the
879 details. Most functions analyzing DNA functions have been
880 modified accordingly and are now much faster (dist.dna is now
881 ca. 60 times faster).
885 CHANGES IN APE VERSION 1.9-4
890 o A bug was fixed in edgelabels().
892 o as.phylo.hclust() did not work correctly when the object of
893 class "hclust" has its labels set to NULL: the returned tree has
894 now its tip labels set to "1", "2", ...
896 o consensus could fail if some tip labels are a subset of others
897 (e.g., "a" and "a_1"): this is now fixed.
899 o mlphylo() failed in most cases if some branch lengths of the
900 initial tree were greater than one: an error message is now
903 o mlphylo() failed in most cases when estimating the proportion of
904 invariants: this is fixed.
908 CHANGES IN APE VERSION 1.9-3
913 o The new function edgelabels adds labels on the edge of the tree
914 in the same way than nodelabels or tiplabels.
919 o multi2di() did not handle correctly branch lengths with the
920 default option `random = TRUE': this is now fixed.
922 o A bug was fixed in nuc.div() when using pairwise deletions.
924 o A bug occurred in the analysis of bipartitions with large
925 numbers of large trees, with consequences on prop.part,
926 prop.clades, and boot.phylo.
928 o The calculation of the Billera-Holmes-Vogtmann distance in
929 dist.topo was wrong: this has been fixed.
933 CHANGES IN APE VERSION 1.9-2

939 a tree to plot them left- or right-ladderized.
941 o The new function dist.nodes computes the patristic distances
942 between all nodes, internal and terminal, of a tree. It replaces

948 o A bug was fixed in old2new.phylo().
950 o Some bugs were fixed in chronopl().
952 o The edge colours were not correctly displayed by plot.phylo
953 (thank you to Li-San Wang for the fix).
955 o cophenetic.phylo() failed with multichotomous trees: this is
961 o read.dna() now returns the sequences in a matrix if they are
962 aligned (interleaved or sequential format). Sequences in FASTA
963 format are still returned in a list.
965 o The option `full' of cophenetic.phylo() has been removed because
966 it could not be used from the generic.
971 o rotate() has been removed; this function did not work correctly
976 CHANGES IN APE VERSION 1.9-1
981 o Trees with a single tip were not read correctly in R as the
982 element `Nnode' was not set: this is fixed.
984 o unroot() did not set correctly the number of nodes of the
985 unrooted tree in most cases.
987 o read.GenBank() failed when fetching very long sequences,
988 particularly of the BX-series.
990 o A bug was introduced in read.tree() with ape 1.9: it has been
995 CHANGES IN APE VERSION 1.9
1000 o There are two new print `methods' for trees of class "phylo" and
1001 lists of trees of class "multi.tree", so that they are now
1002 displayed in a compact and informative way.
1004 o There are two new functions, old2new.phylo and new2old.phylo,
1005 for converting between the old and new coding of the class
1008 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
1009 LogDet ("logdet"), and paralinear ("paralin").
1011 o compute.brlen() has been extended: several methods are now
1012 available to compute branch lengths.
1014 o write.dna() can now handle matrices as well as lists.
1019 o cophenetic.phylo() sometimes returned a wrong result with
1020 multichotomous trees: this is fixed.
1022 o rotate() failed when a single tip was specified: the tree is now
1025 o ace() did not return the correct index matrix with custom
1026 models: this is fixed.
1028 o multi2di() did not work correctly when resolving multichotomies
1029 randomly: the topology was always the same, only the arrangement
1030 of clades was randomized: this is fixed. This function now
1031 accepts trees with no branch lengths.
1033 o The output of diversi.gof() was blurred by useless prints when a
1034 user distribution was specified. This has been corrected, and
1035 the help page of this function has been expanded.
1040 o The internal structure of the class "phylo" has been changed:
1041 see the document "Definition of Formats for Coding Phylogenetic
1042 Trees in R" for the details. In addition, the code of most
1043 functions has been improved.
1045 o Several functions have been improved by replacing some R codes
1046 by C codes: pic, plot.phylo, and reorder.phylo.
1048 o There is now a citation information: see citation("ape") in R.
1050 o write.tree() now does not add extra 0's to branch lengths so
1051 that 1.23 is printed "1.23" by default, not "1.2300000000".
1053 o The syntax of bind.tree() has been simplified. This function now
1054 accepts trees with no branch lengths, and handles correctly node
1057 o The option `as.numeric' of mrca() has been removed.
1059 o The unused options `format' and `rooted' of read.tree() have
1062 o The unused option `format' of write.tree() has been removed.
1064 o The use of node.depth() has been simplified.
1068 CHANGES IN APE VERSION 1.8-5
1073 o Two new functions read.nexus.data() and write.nexus.data(),
1074 contributed by Johan Nylander, allow to read and write molecular
1075 sequences in NEXUS files.
1077 o The new function reorder.phylo() reorders the internal structure
1078 of a tree of class "phylo". It is used as the generic, e.g.,
1081 o read.tree() and read.nexus() can now read trees with a single
1084 o The new data set `cynipids' supplies a set of protein sequences
1090 o The code of all.equal.phylo() has been completely rewritten
1091 (thanks to Benoît Durand) which fixes several bugs.
1093 o read.tree() and read.nexus() now checks the labels of the tree
1094 to remove or substitute any characters that are illegal in the
1095 Newick format (parentheses, etc.)
1097 o A negative P-value could be returned by mantel.test(): this is
1102 CHANGES IN APE VERSION 1.8-4
1107 o The new function sh.test() computes the Shimodaira-
1110 o The new function collapse.singles() removes the nodes with a
1111 single descendant from a tree.
1113 o plot.phylo() has a new argument `tip.color' to specify the
1114 colours of the tips.
1116 o mlphylo() has now an option `quiet' to control the display of
1117 the progress of the analysis (the default is FALSE).
1122 o read.dna() did not read correctly sequences in sequential format
1123 with leading alignment gaps "-": this is fixed.
1125 o ace() returned a list with no class so that the generic
1126 functions (anova, logLik, ...) could not be used directly. This
1127 is fixed as ace() now returns an object of class "ace".
1129 o anova.ace() had a small bug when computing the number of degrees
1130 of freedom: this is fixed.
1132 o mlphylo() did not work when the sequences were in a matrix or
1133 a data frame: this is fixed.
1135 o rtree() did not work correctly when trying to simulate an
1136 unrooted tree with two tips: an error message is now issued.
1141 o The algorithm of rtree() has been changed: it is now about 40,
1142 100, and 130 times faster for 10, 100, and 1000 tips,
1147 CHANGES IN APE VERSION 1.8-3
1152 o There are four new `method' functions to be used with the
1153 results of ace(): logLik(), deviance(), AIC(), and anova().
1155 o The plot method of phymltest has two new arguments: `main' to
1156 change the title, and `col' to control the colour of the
1157 segments showing the AIC values.
1159 o ace() has a new argument `ip' that gives the initial values used
1160 in the ML estimation with discrete characters (see the examples
1161 in ?ace). This function now returns a matrix giving the indices
1162 of the estimated rates when analysing discrete characters.
1164 o nodelabels() and tiplabels() have a new argument `pie' to
1165 represent proportions, with any number of categories, as
1166 piecharts. The use of the option `thermo' has been improved:
1167 there is now no limitation on the number of categories.
1172 o mlphylo() did not work with more than two partitions: this is
1175 o root() failed if the proposed outgroup was already an outgroup
1176 in the tree: this is fixed.
1178 o The `col' argument in nodelabels() and tiplabels() was not
1179 correctly passed when `text' was used: this is fixed.
1181 o Two bugs were fixed in mlphylo(): parameters were not always
1182 correctly output, and the estimation failed in some cases.
1184 o plot.phylo() was stuck when given a tree with a single tip: this
1185 is fixed and a message error is now returned.
1187 o An error was corrected in the help page of gammaStat regarding
1188 the calculation of P-values.
1190 o Using gls() could crash R when the number of species in the tree
1191 and in the variables were different: this is fixed.
1195 CHANGES IN APE VERSION 1.8-2
1200 o The new function mlphylo() fits a phylogenetic tree by maximum
1201 likelihood from DNA sequences. Its companion function DNAmodel()
1202 is used to define the substitution model which may include
1203 partitioning. There are methods for logLik(), deviance(), and
1204 AIC(), and the summary() method has been extended to display in
1205 a friendly way the results of this model fitting. Currently, the
1206 functionality is limited to estimating the substitution and
1207 associated parameters and computing the likelihood.
1209 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1210 tests for single effects in GEE-based comparative method. A
1211 warning message is printed if there is not enough degrees of
1217 o An error message was sometimes issued by plot.multi.tree(),
1218 though with no consequence.
1222 CHANGES IN APE VERSION 1.8-1
1227 o There is a new plot method for lists of trees (objects of class
1228 "multi.tree"): it calls plot.phylo() internally and is
1229 documented on the same help page.
1234 o A bug was fixed in the C code that analyzes bipartitions: this
1235 has impact on several functions like prop.part, prop.clades,
1236 boot.phylo, or consensus.
1238 o root() did not work correctly when the specified outgroup had
1239 more than one element: this is fixed.
1241 o dist.dna() sometimes returned a warning inappropriately: this
1244 o If the distance object given to nj() had no rownames, nj()
1245 returned a tree with no tip labels: it now returns tips labelled
1246 "1", "2", ..., corresponding to the row numbers.
1251 o nj() has been slightly changed so that tips with a zero distance
1252 are first aggregated with zero-lengthed branches; the usual NJ
1253 procedure is then performed on a distance matrix without 0's.
1257 CHANGES IN APE VERSION 1.8
1262 o The new function chronopl() estimates dates using the penalized
1263 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1265 o The new function consensus() calculates the consensus tree of a
1268 o The new function evolve.phylo() simulates the evolution of
1269 continuous characters along a phylogeny under a Brownian model.
1271 o The new plot method for objects of class "ancestral" displays a
1272 tree together with ancestral values, as returned by the above
1275 o The new function as.phylo.formula() returns a phylogeny from a
1276 set of nested taxonomic variables given as a formula.
1278 o The new function read.caic() reads trees in CAIC format.
1280 o The new function tiplabels() allows to add labels to the tips
1281 of a tree using text or plotting symbols in a flexible way.
1283 o The new function unroot() unroots a phylogeny.
1285 o multi2di() has a new option, `random', which specifies whether
1286 to resolve the multichotomies randomly (the default) or not.
1288 o prop.part() now returns an object of class "prop.part" for which
1289 there are print (to display a partition in a more friendly way)
1290 and summary (to extract the numbers) methods.
1292 o plot.phylo() has a new option, `show.tip.label', specifying
1293 whether to print the labels of the tips. The default is TRUE.
1295 o The code of nj() has been replaced by a faster C code: it is now
1296 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1299 o write.nexus() now writes whether a tree is rooted or not.
1304 o Two bugs have been fixed in root(): unrooted trees are now
1305 handled corretly, and node labels are now output normally.
1307 o A bug was fixed in phymltest(): the executable couldn't be found
1310 o Three bug have been fixed in ace(): computing the likelihood of
1311 ancestral states of discrete characters failed, custom models
1312 did not work, and the function failed with a null gradient (a
1313 warning message is now returned; this latter bug was also
1314 present in yule.cov() as well and is now fixed).
1316 o pic() hanged out when missing data were present: a message error
1319 o A small bug was fixed in dist.dna() where the gamma correction
1320 was not always correctly dispatched.
1322 o plot.phylo() plotted correctly the root edge only when the tree
1323 was plotted rightwards: this works now for all directions.
1328 o dist.taxo() has been renamed as weight.taxo().
1330 o dist.phylo() has been replaced by the method cophenetic.phylo().
1332 o Various error and warning messages have been improved.
1336 CHANGES IN APE VERSION 1.7
1339 o The new function ace() estimates ancestral character states for
1340 continuous characters (with ML, GLS, and contrasts methods), and
1341 discrete characters (with ML only) for any number of states.
1343 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1344 of directional evolution for continuous characters. The user
1345 specifies the node(s) of the tree where the character optimum
1348 o The new function is.rooted() tests whether a tree (of class
1351 o The new function rcoal() generates random ultrametric trees with
1352 the possibility to specify the function that generates the
1353 inter-nodes distances.
1355 o The new function mrca() gives for all pairs of tips in a tree
1356 (and optionally nodes too) the most recent common ancestor.
1358 o nodelabels() has a new option `thermo' to plot proportions (up
1359 to three classes) on the nodes of a tree.
1361 o rtree() has been improved: it can now generate rooted or
1362 unrooted trees, and the mathematical function that generates the
1363 branch lengths may be specified by the user. The tip labels may
1364 be given directly in the call to rtree. The limit cases (n = 2,
1365 3) are now handled correctly.
1367 o dist.topo() has a new argument `method' with two choices: "PH85"
1368 for Penny and Henny's method (already available before and now
1369 the default), and "BHV01" for the geometric distance by Billera
1370 et al. (2001, Adv. Appl. Math. 27:733).
1372 o write.tree() has a new option, `digits', which specifies the
1373 number of digits to be printed in the Newick tree. By default
1374 digits = 10. The numbers are now always printed in decimal form
1375 (i.e., 1.0e-1 is now avoided).
1377 o dist.dna() can now compute the raw distances between pairs of
1378 DNA sequences by specifying model = "raw".
1380 o dist.phylo() has a new option `full' to possibly compute the
1381 distances among all tips and nodes of the tree. The default if
1387 o Several bugs were fixed in all.equal.phylo().
1389 o dist.dna() did not handle correctly gaps ("-") in alignments:
1390 they are now considered as missing data.
1392 o rotate() did not work if the tips were not ordered: this is
1395 o mantel.test() returned NA in some special cases: this is fixed
1396 and the function has been improved and is now faster.
1398 o A bug was fixed in diversi.gof() where the calculation of A² was
1401 o cherry() did not work correctly under some OSs (mainly Linux):
1404 o is.binary.tree() has been modified so that it works with both
1405 rooted and unrooted trees.
1407 o The documentation of theta.s() was not correct: this has been
1410 o plot.mst() did not work correctly: this is fixed.
1414 CHANGES IN APE VERSION 1.6
1419 o The new function dist.topo() computes the topological distances
1422 o The new function boot.phylo() performs a bootstrap analysis on
1423 phylogeny estimation.
1425 o The new functions prop.part() and prop.clades() analyse
1426 bipartitions from a series of trees.
1431 o read.GenBank() now uses the EFetch utility of NCBI instead of
1432 the usual Web interface: it is now much faster (e.g., 12 times
1433 faster to retrieve 8 sequences, 37 times for 60 sequences).
1438 o Several bugs were fixed in read.dna().
1440 o Several bugs were fixed in diversi.time().
1442 o is.binary.tree() did not work correctly if the tree has no edge
1443 lengths: this is fixed.
1445 o drop.tip() did not correctly propagated the `node.label' of a
1446 tree: this is fixed.
1450 CHANGES IN APE VERSION 1.5
1455 o Two new functions, as.matching.phylo() and as.phylo.matching(),
1456 convert objects between the classes "phylo" and "matching". The
1457 latter implements the representation of binary trees introduced by
1458 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
1459 as.matching() has been introduced as well.
1461 o Two new functions, multi2di() and di2multi(), allow to resolve
1462 and collapse multichotomies with branches of length zero.
1464 o The new function nuc.div() computes the nucleotide diversity
1465 from a sample a DNA sequences.
1467 o dist.dna() has been completely rewritten with a much faster
1468 (particularly for large data sets) C code. Eight models are
1469 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
1470 option `method' has been renamed `model'). Computation of variance
1471 is available for all models. A gamma-correction is possible for
1472 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
1473 to remove sites with missing data on a pairwise basis. The option
1474 `GCcontent' has been removed.
1476 o read.GenBank() has a new option (species.names) which specifies
1477 whether to return the species names of the organisms in addition
1478 to the accession numbers of the sequences (this is the default
1481 o write.nexus() can now write several trees in the same NEXUS file.
1483 o drop.tip() has a new option `root.edge' that allows to specify the
1484 new root edge if internal branches are trimmed.
1489 o as.phylo.hclust() failed if some labels had parentheses: this
1492 o Several bugs were fixed in all.equal.phylo(). This function now
1493 returns the logical TRUE if the trees are identical but with
1494 different representations (a report was printed previously).
1496 o read.GenBank() did not correctly handle ambiguous base codes:
1502 o birthdeath() now returns an object of class "birthdeath" for
1503 which there is a print method.
1507 CHANGES IN APE VERSION 1.4
1512 o The new function nj() performs phylogeny estimation with the
1513 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
1516 o The new function which.edge() identifies the edges of a tree
1517 that belong to a group specified as a set of tips.
1519 o The new function as.phylo.phylog() converts an object of class
1520 "phylog" (from the package ade4) into an object of class
1523 o The new function axisPhylo() draws axes on the side of a
1526 o The new function howmanytrees() calculates the number of trees
1527 in different cases and giving a number of tips.
1529 o write.tree() has a new option `multi.line' (TRUE by default) to
1530 write a Newick tree on several lines rather than on a single
1533 o The functionalities of zoom() have been extended. Several
1534 subtrees can be visualized at the same time, and they are marked
1535 on the main tree with colors. The context of the subtrees can be
1536 marked with the option `subtree' (see below).
1538 o drop.tip() has a new option `subtree' (FALSE by default) which
1539 specifies whether to output in the tree how many tips have been
1542 o The arguments of add.scale.bar() have been redefined and have
1543 now default values (see ?add.scale.bar for details). This
1544 function now works even if the plotted tree has no edge length.
1546 o plot.phylo() can now plot radial trees, but this does not take
1547 edge lengths into account.
1549 o In plot.phylo() with `type = "phylogram"', if the values of
1550 `edge.color' and `edge.width' are identical for sister-branches,
1551 they are propagated to the vertical line that link them.
1556 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
1557 crashing. This is fixed.
1559 o In plot.phylo(), the options `edge.color' and `edge.width' are
1560 now properly recycled; their default values are now "black" and
1563 o A bug has been fixed in write.nexus().
1568 o The function node.depth.edgelength() has been removed and
1569 replaced by a C code.
1573 CHANGES IN APE VERSION 1.3-1
1578 o The new function nodelabels() allows to add labels to the nodes
1579 of a tree using text or plotting symbols in a flexible way.
1581 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
1582 numeric values specifying the lower and upper limits on the x-
1583 and y-axes. This allows to leave some space on any side of the
1584 tree. If a single value is given, this is taken as the upper
1589 CHANGES IN APE VERSION 1.3
1594 o The new function phymltest() calls the software PHYML and fits
1595 28 models of DNA sequence evolution. There are a print method to
1596 display likelihood and AIC values, a summary method to compute
1597 the hierarchical likelihood ratio tests, and a plot method to
1598 display graphically the AIC values of each model.
1600 o The new function yule.cov() fits the Yule model with covariates,
1601 a model where the speciation rate is affected by several species
1602 traits through a generalized linear model. The parameters are
1603 estimated by maximum likelihood.
1605 o Three new functions, corBrownian(), corGrafen(), and
1606 corMartins(), compute the expected correlation structures among
1607 species given a phylogeny under different models of evolution.
1608 These can be used for GLS comparative phylogenetic methods (see
1609 the examples). There are coef() and corMatrix() methods and an
1610 Initialize.corPhyl() function associated.
1612 o The new function compar.cheverud() implements Cheverud et al.'s
1613 (1985; Evolution 39:1335) phylogenetic comparative method.
1615 o The new function varcomp() estimates variance components; it has
1618 o Two new functions, panel.superpose.correlogram() and
1619 plot.correlogramList(), allow to plot several phylogenetic
1622 o The new function node.leafnumber() computes the number of leaves
1623 of a subtree defined by a particular node.
1625 o The new function node.sons() gets all tags of son nodes from a
1628 o The new function compute.brlen() computes the branch lengths of
1629 a tree according to a specified method.
1631 o plot.phylo() has three new options: "cex" controls the size of
1632 the (tip and node) labels (thus it is no more needed to change
1633 the global graphical parameter), "direction" which allows to
1634 plot the tree rightwards, leftwards, upwards, or downwards, and
1635 "y.lim" which sets the upper limit on the y-axis.
1640 o Some functions which try to match tip labels and names of
1641 additional data (e.g. vector) are likely to fail if there are
1642 typing or syntax errors. If both series of names do not perfectly
1643 match, they are ignored and a warning message is now issued.
1644 These functions are bd.ext, compar.gee, pic. Their help pages
1645 have been clarified on this point.
1649 CHANGES IN APE VERSION 1.2-7
1654 o The new function root() reroots a phylogenetic tree with respect
1655 to a specified outgroup.
1657 o The new function rotate() rotates an internal branch of a tree.
1659 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
1660 trees) controls the display of the tip labels in unrooted trees.
1661 This display has been greatly improved: the tip labels are now not
1662 expected to overlap with the tree (particularly if lab4ut =
1663 "axial"). In all cases, combining appropriate values of "lab4ut"
1664 and the font size (via "par(cex = )") should result in readable
1665 unrooted trees. See ?plot.phylo for some examples.
1667 o In drop.tip(), the argument `tip' can now be numeric or character.
1672 o drop.tip() did not work correctly with trees with no branch
1673 lengths: this is fixed.
1675 o A bug in plot.phylo(..., type = "unrooted") made some trees being
1676 plotted with some line crossings: this is now fixed.
1680 CHANGES IN APE VERSION 1.2-6
1685 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
1686 correlogram.phylo, dist.taxo, plot.correlogram) have been added
1687 to implement comparative methods with an autocorrelation approach.
1689 o A new data set describing some life history traits of Carnivores
1695 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
1700 o When plotting a tree with plot.phylo(), the new default of the
1701 option `label.offset' is now 0, so the labels are always visible.
1705 CHANGES IN APE VERSION 1.2-5
1710 o The new function bd.ext() fits a birth-death model with combined
1711 phylogenetic and taxonomic data, and estimates the corresponding
1712 speciation and extinction rates.
1717 o The package gee is no more required by ape but only suggested
1718 since only the function compar.gee() calls gee.
1722 CHANGES IN APE VERSION 1.2-4
1727 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
1728 and lines.popsize) implementing a new approach for inferring the
1729 demographic history from genealogies using a reversible jump
1730 MCMC have been introduced.
1732 o The unit of time in the skyline plot and in the new plots can
1733 now be chosen to be actual years, rather than substitutions.
1737 CHANGES IN APE VERSION 1.2-3
1742 o The new function rtree() generates a random binary tree with or
1743 without branch lengths.
1745 o Two new functions for drawing lineages-through-time (LTT) plots
1746 are provided: ltt.lines() adds a LTT curve to an existing plot,
1747 and mltt.plot() does a multiple LTT plot giving several trees as
1748 arguments (see `?ltt.plot' for details).
1753 o Some taxon names made R crashing when calling as.phylo.hclust():
1756 o dist.dna() returned an error with two identical DNA sequences
1757 (only using the Jukes-Cantor method returned 0): this is fixed.
1762 o The function dist.phylo() has been re-written using a different
1763 algorithm: it is now about four times faster.
1765 o The code of branching.times() has been improved: it is now about
1770 CHANGES IN APE VERSION 1.2-2
1775 o The new function seg.sites() finds the segregating sites in a
1776 sample of DNA sequences.
1781 o A bug introduced in read.tree() and in read.nexus() with version
1784 o A few errors were corrected and a few examples were added in the
1789 CHANGES IN APE VERSION 1.2-1
1794 o plot.phylo() can now draw the edge of the root of a tree if it
1795 has one (see the new option `root.edge', its default is FALSE).
1800 o A bug was fixed in read.nexus(): files with semicolons inside
1801 comment blocks were not read correctly.
1803 o The behaviour of read.tree() and read.nexus() was corrected so
1804 that tree files with badly represented root edges (e.g., with
1805 an extra pair of parentheses, see the help pages for details)
1806 are now correctly represented in the object of class "phylo";
1807 a warning message is now issued.
1811 CHANGES IN APE VERSION 1.2
1816 o plot.phylo() has been completely re-written and offers several
1817 new functionalities. Three types of trees can now be drawn:
1818 phylogram (as previously), cladogram, and unrooted tree; in
1819 all three types the branch lengths can be drawn using the edge
1820 lengths of the phylogeny or not (e.g., if the latter is absent).
1821 The vertical position of the nodes can be adjusted with two
1822 choices (see option `node.pos'). The code has been re-structured,
1823 and two new functions (potentially useful for developpers) are
1824 documented separately: node.depth.edgelength() and node.depth();
1825 see the respective help pages for details.
1827 o The new function zoom() allows to explore very large trees by
1828 focusing on a small portion of it.
1830 o The new function yule() fits by maximum likelihood the Yule model
1831 (birth-only process) to a phylogenetic tree.
1833 o Support for writing DNA sequences in FASTA format has been
1834 introduced in write.dna() (support for reading sequences in
1835 this format was introduced in read.dna() in version 1.1-2).
1836 The function has been completely re-written, fixing some bugs
1837 (see below); the default behaviour is no more to display the
1838 sequences on the standard output. Several options have been
1839 introduced to control the sequence printing in a flexible
1840 way. The help page has been extended.
1842 o A new data set is included: a supertree of bats in NEXUS format.
1847 o In theta.s(), the default of the option `variance' has
1848 been changed to `FALSE' (as was indicated in the help page).
1850 o Several bugs were fixed in the code of all.equal.phylo().
1852 o Several bugs were fixed in write.dna(), particularly this
1853 function did not work with `format = "interleaved"'.
1855 o Various errors were corrected in the help pages.
1860 o The argument names of as.hclust.phylo() have been changed
1861 from "(phy)" to "(x, ...)" to conform to the definition of
1862 the corresponding generic function.
1864 o gamma.stat() has been renamed gammaStat() to avoid confusion
1865 since gamma() is a generic function.
1869 CHANGES IN APE VERSION 1.1-3
1874 o base.freq() previously did not return a value of 0 for
1875 bases absent in the data (e.g., a vector of length 3 was
1876 returned if one base was absent). This is now fixed (a
1877 vector of length 4 is always returned).
1879 o Several bugs were fixed in read.nexus(), including that this
1880 function did not work in this absence of a "TRANSLATE"
1881 command in the NEXUS file, and that the commands were
1886 CHANGES IN APE VERSION 1.1-2
1891 o The Tamura and Nei (1993) model of DNA distance is now implemented
1892 in dist.dna(): five models are now available in this function.
1894 o A new data set is included: a set of 15 sequences of the
1895 cytochrome b mitochondrial gene of the woodmouse (Apodemus
1901 o A bug in read.nexus() was fixed.
1903 o read.dna() previously did not work correctly in most cases.
1904 The function has been completely re-written and its help page
1905 has been considerably extended (see ?read.dna for details).
1906 Underscores (_) in taxon names are no more replaced with
1907 spaces (this behaviour was undocumented).
1909 o A bug was fixed in write.dna().
1913 CHANGES IN APE VERSION 1.1-1
1918 o A bug in read.tree() introduced in APE 1.1 was fixed.
1920 o A bug in compar.gee() resulted in an error when trying to fit
1921 a model with `family = "binomial"'. This is now fixed.
1925 CHANGES IN APE VERSION 1.1
1930 o The Klastorin (1982) method as suggested by Misawa and Tajima
1931 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
1932 on the basis of phylogenetic trees has been implemented (see
1933 the function klastorin()).
1935 o Functions have been added to convert APE's "phylo" objects in
1936 "hclust" cluster objects and vice versa (see the help page of
1937 as.phylo for details).
1939 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
1940 are introduced for the estimation of absolute evolutionary rates
1941 (ratogram) and dated clock-like trees (chronogram) from
1942 phylogenetic trees using the non-parametric rate smoothing approach
1943 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
1945 o A summary method is now provided printing a summary information on a
1946 phylogenetic tree with, for instance, `summary(tree)'.
1948 o The behaviour of read.tree() was changed so that all spaces and
1949 tabulations in tree files are now ignored. Consequently, spaces in tip
1950 labels are no more allowed. Another side effect is that read.nexus()
1951 now does not replace the underscores (_) in tip labels with spaces
1952 (this behaviour was undocumented).
1954 o The function plot.phylo() has a new option (`underscore') which
1955 specifies whether the underscores in tip labels should be written on
1956 the plot as such or replaced with spaces (the default).
1958 o The function birthdeath() now computes 95% confidence intervals of
1959 the estimated parameters using profile likelihood.
1961 o Three new data sets are included: a gene tree estimated from 36
1962 landplant rbcL sequences, a gene tree estimated from 32 opsin
1963 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
1968 o A bug was fixed in dist.gene() where nothing was returned.
1970 o A bug in plot.mst() was fixed.
1972 o A bug in vcv.phylo() resulted in false correlations when the
1973 option `cor = TRUE' was used (now fixed).
1977 CHANGES IN APE VERSION 1.0
1982 o Two new functions, read.dna() and write.dna(), read/write in a file
1983 DNA sequences in interleaved or in sequential format.
1985 o Two new functions, read.nexus() and write.nexus(), read/write trees
1988 o The new function bind.tree() allows to bind two trees together,
1989 possibly handling root edges to give internal branches.
1991 o The new function drop.tip() removes the tips in a phylogenetic tree,
1992 and trims (or not) the corresponding internal branches.
1994 o The new function is.ultrametric() tests if a tree is ultrametric.
1996 o The function plot.phylo() has more functionalities such as drawing the
1997 branches with different colours and/or different widths, showing the
1998 node labels, controling the position and font of the labels, rotating
1999 the labels, and controling the space around the plot.
2001 o The function read.tree() can now read trees with no branch length,
2002 such as "(a,b),c);". Consequently, the element `edge.length' in
2003 objects of class "phylo" is now optional.
2005 o The function write.tree() has a new default behaviour: if the default
2006 for the option `file' is used (i.e. file = ""), then a variable of
2007 mode character containing the tree in Newick format is returned which
2008 can thus be assigned (e.g., tree <- write.tree(phy)).
2010 o The function read.tree() has a new argument `text' which allows
2011 to read the tree in a variable of mode character.
2013 o A new data set is included: the phylogenetic relationships among
2014 the orders of birds from Sibley and Ahlquist (1990).
2018 CHANGES IN APE VERSION 0.2-1
2023 o Several bugs were fixed in the help pages.
2027 CHANGES IN APE VERSION 0.2
2032 o The function write.tree() writes phylogenetic trees (objects of class
2033 "phylo") in an ASCII file using the Newick parenthetic format.
2035 o The function birthdeath() fits a birth-death model to branching times
2036 by maximum likelihood, and estimates the corresponding speciation and
2039 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2042 o The function is.binary.tree() tests whether a phylogeny is binary.
2044 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2045 as well as some methods are introduced.
2047 o Several functions, including some generics and methods, for computing
2048 skyline plot estimates (classic and generalized) of effective
2049 population size through time are introduced and replace the function
2050 skyline.plot() in version 0.1.
2052 o Two data sets are now included: the phylogenetic relationships among
2053 the families of birds from Sibley and Ahlquist (1990), and an
2054 estimated clock-like phylogeny of HIV sequences sampled in the
2055 Democratic Republic of Congo.
2058 DEPRECATED & DEFUNCT
2060 o The function skyline.plot() in ape 0.1 has been deprecated and
2061 replaced by more elaborate functions (see above).
2066 o Two important bugs were fixed in plot.phylo(): phylogenies with
2067 multichotomies not at the root or not with only terminal branches,
2068 and phylogenies with a single node (i.e. only terminal branches)
2069 did not plot. These trees should be plotted correctly now.
2071 o Several bugs were fixed in diversi.time() in the computation of
2074 o Various errors were corrected in the help pages.
