30 o drop.tip(), extract.clade(), root(), and bind.tree() now have an
31 'interactive' option to make the operation on a plotted tree.
33 o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
34 association links; they are recycled like 'col' (which wasn't before).
39 o rTraitDisc() did not use its 'freq' argument correctly (it was
40 multiplied with the rate matrix column-wise instead of row-wise).
42 o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
43 with NA values. Nothing is drawn now like with 'text' or 'pch'.
44 The same bug occurred with the 'pie' option.
46 o A bug was fixed in compar.ou() and the help page was clarified.
48 o bind.tree() has been rewritten fixing several bugs and making it
51 o plot.phylo(type = "p") sometimes failed to colour correctly the
52 vertical lines representing the nodes.
54 o plot.phylo(direction = "l", x.lim = 30) failed to plot the branches
55 in the correct direction though the tip labels were displayed
61 o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
62 the sequences are correctly stored (in a list for c, in a matrix
63 for the two other functions).
67 CHANGES IN APE VERSION 2.5
72 o The new function parafit by Pierre Legendre tests for the
73 coevolution between hosts and parasites. It has a companion

77 o The new function lmorigin by Pierre Legendre performs multiple
78 regression through the origin with testing by permutation.
80 o The new functions rTraitCont and rTraitDisc simulate continuous and
81 discrete traits under a wide range of evolutionary models.

94 o The branch length score replaces the geodesic distance in dist.topo.
96 o Three new data sets are included: the gopher-lice data (gopher.D),
97 SO2 air pollution in 41 US cities (lmorigin.ex1, from Sokal &
98 Rohlf 1995), and some host-parasite specificity data
99 (lmorigin.ex2, from Legendre & Desdevises 2009).
104 o add.scale.bar() drew the bar outside the plotting region with the
105 default options with unrooted or radial trees.
107 o dist.topo() made R stuck when the trees had different sizes (thanks

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

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

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

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

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

268 corrected with respect to this change.
270 o drop.tip() has a new option 'rooted' to force (or not) a tree
271 to be treated as (un)rooted.
276 o dist.gene() failed on most occasions with the default
277 pairwise.deletion = FALSE.

333 o phymltest() has been updated to work with PhyML 3.0.1.
338 o drop.tip() shuffled tip labels in some cases.

383 specifying model="N".
388 o chronopl() did not work with CV = TRUE.
390 o read.nexus() did not work correctly in some situations (trees on
391 multiple lines with different numbers of lines and/or with
392 comments inserted within the trees).

395 the number of lineages with non-binary trees.
400 o ape has now a namespace.
402 o drop.tip() has been improved: it should be much faster and work
403 better in some cases (e.g., see the example in ?zoom).
407 CHANGES IN APE VERSION 2.2-2
412 o dist.gene() has been substantially improved and gains an option
415 o cbind.DNAbin() has a new option 'fill.with.gaps' and is now
421 o prop.part() failed with a single tree with the default option
422 'check.labels = TRUE'.
424 o summary.DNAbin() failed to display correctly the summary of
425 sequence lengths with lists of sequences of 10,000 bases or more
426 (because summary.default uses 4 significant digits by default).
428 o read.nexus() failed to read a file with a single tree with line
429 breaks in the Newick string.
431 o del.gaps() returned a list of empty sequences when there were no

438 'append', whereas the option 'path2exec' has been removed.
440 o rbind.DNAbin() and cbind.DNAbin() now accept a single matrix
441 which is returned unchanged (instead of an error).
443 o The data sets bird.orders and bird.families are now stored as
444 Newick strings; i.e., the command data(bird.orders) calls
449 CHANGES IN APE VERSION 2.2-1
454 o The new function makeLabel() helps to modify labels of trees,
455 lists of trees, or DNA sequences, with several utilities to
456 truncate and/or make them unique, substituting some
457 characters, and so on.
459 o The new function del.gaps() removes insertion gaps ("-") in a
460 set of DNA sequences.

492 o The option 'check.labels' of consensus() and prop.part() is now
495 o write.dna() now does not truncate names to 10 characters with
500 CHANGES IN APE VERSION 2.2
505 o Four new functions have been written by Damien de Vienne for the
506 graphical exploration of large trees (cophyloplot, subtrees,
507 subtreeplot), and to return the graphical coordinates of tree

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

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

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

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

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

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

745 limited number of labelled topologies could be generated.
749 CHANGES IN APE VERSION 2.0-1
754 o The three new functions bionj, fastme.ols, and fastme.bal
755 perform phylogeny estimation by the BIONJ and fastME methods in
756 OLS and balanced versions. This is a port to R of previous

759 o The new function chronoMPL performs molecular dating with the
760 mean path lengths method of Britton et al. (2002, Mol. Phyl.
763 o The new function rotate, contributed by Christoph Heibl, swaps
764 two clades connected to the same node. It works also with
765 multichotomous nodes.
767 o The new `method' as.matrix.DNAbin() may be used to convert
768 easily DNA sequences stored in a list into a matrix while
769 keeping the names and the class.
774 o chronopl() failed when some branch lengths were equal to zero:
775 an error message is now returned.
777 o di2multi() failed when there was a series of consecutive edges
782 CHANGES IN APE VERSION 1.10-2
787 o plot.phylo() can now plot circular trees: the option is type =
788 "fan" or type = "f" (to avoid the ambiguity with type = "c").
790 o prop.part() has a new option `check.labels = FALSE' which allows
791 to considerably speed-up the calculations of bipartitions. As a
792 consequence, calculations of bootstrap values with boot.phylo()
793 should be much faster.
798 o read.GenBank() did not return correctly the list of species as
799 from ape 1.10: this is fixed in this version
801 o Applying as.phylo() on a tree of class "phylo" failed: the
802 object is now returned unchanged.

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

859 the default setting: this is fixed.
861 o dist.dna() returned a wrong result for the LogDet, paralinear,
862 and BH87 models with `pairwise.deletion = TRUE'.
867 o DNA sequences are now internally stored in a binary format. See
868 the document "A Bit-Level Coding Scheme for Nucleotides" for the
869 details. Most functions analyzing DNA functions have been
870 modified accordingly and are now much faster (dist.dna is now
871 ca. 60 times faster).
875 CHANGES IN APE VERSION 1.9-4
880 o A bug was fixed in edgelabels().
882 o as.phylo.hclust() did not work correctly when the object of
883 class "hclust" has its labels set to NULL: the returned tree has
884 now its tip labels set to "1", "2", ...
886 o consensus could fail if some tip labels are a subset of others
887 (e.g., "a" and "a_1"): this is now fixed.
889 o mlphylo() failed in most cases if some branch lengths of the
890 initial tree were greater than one: an error message is now
893 o mlphylo() failed in most cases when estimating the proportion of
894 invariants: this is fixed.
898 CHANGES IN APE VERSION 1.9-3
903 o The new function edgelabels adds labels on the edge of the tree
904 in the same way than nodelabels or tiplabels.
909 o multi2di() did not handle correctly branch lengths with the
910 default option `random = TRUE': this is now fixed.
912 o A bug was fixed in nuc.div() when using pairwise deletions.
914 o A bug occurred in the analysis of bipartitions with large
915 numbers of large trees, with consequences on prop.part,
916 prop.clades, and boot.phylo.
918 o The calculation of the Billera-Holmes-Vogtmann distance in
919 dist.topo was wrong: this has been fixed.
923 CHANGES IN APE VERSION 1.9-2

929 a tree to plot them left- or right-ladderized.
931 o The new function dist.nodes computes the patristic distances
932 between all nodes, internal and terminal, of a tree. It replaces
933 the option `full = TRUE' of cophenetic.phylo (see below).
938 o A bug was fixed in old2new.phylo().
940 o Some bugs were fixed in chronopl().
942 o The edge colours were not correctly displayed by plot.phylo
943 (thank you to Li-San Wang for the fix).
945 o cophenetic.phylo() failed with multichotomous trees: this is
951 o read.dna() now returns the sequences in a matrix if they are
952 aligned (interleaved or sequential format). Sequences in FASTA
953 format are still returned in a list.
955 o The option `full' of cophenetic.phylo() has been removed because
956 it could not be used from the generic.
961 o rotate() has been removed; this function did not work correctly
966 CHANGES IN APE VERSION 1.9-1
971 o Trees with a single tip were not read correctly in R as the
972 element `Nnode' was not set: this is fixed.
974 o unroot() did not set correctly the number of nodes of the
975 unrooted tree in most cases.
977 o read.GenBank() failed when fetching very long sequences,
978 particularly of the BX-series.
980 o A bug was introduced in read.tree() with ape 1.9: it has been
985 CHANGES IN APE VERSION 1.9
990 o There are two new print `methods' for trees of class "phylo" and
991 lists of trees of class "multi.tree", so that they are now
992 displayed in a compact and informative way.
994 o There are two new functions, old2new.phylo and new2old.phylo,
995 for converting between the old and new coding of the class
998 o dist.dna() has three new models: Barry and Hartigan ("BH87"),
999 LogDet ("logdet"), and paralinear ("paralin").
1001 o compute.brlen() has been extended: several methods are now
1002 available to compute branch lengths.
1004 o write.dna() can now handle matrices as well as lists.
1009 o cophenetic.phylo() sometimes returned a wrong result with
1010 multichotomous trees: this is fixed.
1012 o rotate() failed when a single tip was specified: the tree is now
1015 o ace() did not return the correct index matrix with custom
1016 models: this is fixed.
1018 o multi2di() did not work correctly when resolving multichotomies
1019 randomly: the topology was always the same, only the arrangement
1020 of clades was randomized: this is fixed. This function now
1021 accepts trees with no branch lengths.
1023 o The output of diversi.gof() was blurred by useless prints when a
1024 user distribution was specified. This has been corrected, and
1025 the help page of this function has been expanded.
1030 o The internal structure of the class "phylo" has been changed:
1031 see the document "Definition of Formats for Coding Phylogenetic
1032 Trees in R" for the details. In addition, the code of most
1033 functions has been improved.
1035 o Several functions have been improved by replacing some R codes
1036 by C codes: pic, plot.phylo, and reorder.phylo.
1038 o There is now a citation information: see citation("ape") in R.
1040 o write.tree() now does not add extra 0's to branch lengths so
1041 that 1.23 is printed "1.23" by default, not "1.2300000000".
1043 o The syntax of bind.tree() has been simplified. This function now
1044 accepts trees with no branch lengths, and handles correctly node
1047 o The option `as.numeric' of mrca() has been removed.
1049 o The unused options `format' and `rooted' of read.tree() have
1052 o The unused option `format' of write.tree() has been removed.
1054 o The use of node.depth() has been simplified.
1058 CHANGES IN APE VERSION 1.8-5
1063 o Two new functions read.nexus.data() and write.nexus.data(),
1064 contributed by Johan Nylander, allow to read and write molecular
1065 sequences in NEXUS files.
1067 o The new function reorder.phylo() reorders the internal structure
1068 of a tree of class "phylo". It is used as the generic, e.g.,
1071 o read.tree() and read.nexus() can now read trees with a single
1074 o The new data set `cynipids' supplies a set of protein sequences
1080 o The code of all.equal.phylo() has been completely rewritten
1081 (thanks to Benoît Durand) which fixes several bugs.
1083 o read.tree() and read.nexus() now checks the labels of the tree
1084 to remove or substitute any characters that are illegal in the
1085 Newick format (parentheses, etc.)
1087 o A negative P-value could be returned by mantel.test(): this is
1092 CHANGES IN APE VERSION 1.8-4
1097 o The new function sh.test() computes the Shimodaira-
1100 o The new function collapse.singles() removes the nodes with a
1101 single descendant from a tree.
1103 o plot.phylo() has a new argument `tip.color' to specify the
1104 colours of the tips.
1106 o mlphylo() has now an option `quiet' to control the display of
1107 the progress of the analysis (the default is FALSE).
1112 o read.dna() did not read correctly sequences in sequential format
1113 with leading alignment gaps "-": this is fixed.
1115 o ace() returned a list with no class so that the generic
1116 functions (anova, logLik, ...) could not be used directly. This
1117 is fixed as ace() now returns an object of class "ace".
1119 o anova.ace() had a small bug when computing the number of degrees
1120 of freedom: this is fixed.
1122 o mlphylo() did not work when the sequences were in a matrix or
1123 a data frame: this is fixed.
1125 o rtree() did not work correctly when trying to simulate an
1126 unrooted tree with two tips: an error message is now issued.
1131 o The algorithm of rtree() has been changed: it is now about 40,
1132 100, and 130 times faster for 10, 100, and 1000 tips,
1137 CHANGES IN APE VERSION 1.8-3
1142 o There are four new `method' functions to be used with the
1143 results of ace(): logLik(), deviance(), AIC(), and anova().
1145 o The plot method of phymltest has two new arguments: `main' to
1146 change the title, and `col' to control the colour of the
1147 segments showing the AIC values.
1149 o ace() has a new argument `ip' that gives the initial values used
1150 in the ML estimation with discrete characters (see the examples
1151 in ?ace). This function now returns a matrix giving the indices
1152 of the estimated rates when analysing discrete characters.
1154 o nodelabels() and tiplabels() have a new argument `pie' to
1155 represent proportions, with any number of categories, as
1156 piecharts. The use of the option `thermo' has been improved:
1157 there is now no limitation on the number of categories.
1162 o mlphylo() did not work with more than two partitions: this is
1165 o root() failed if the proposed outgroup was already an outgroup
1166 in the tree: this is fixed.
1168 o The `col' argument in nodelabels() and tiplabels() was not
1169 correctly passed when `text' was used: this is fixed.
1171 o Two bugs were fixed in mlphylo(): parameters were not always
1172 correctly output, and the estimation failed in some cases.
1174 o plot.phylo() was stuck when given a tree with a single tip: this
1175 is fixed and a message error is now returned.
1177 o An error was corrected in the help page of gammaStat regarding
1178 the calculation of P-values.
1180 o Using gls() could crash R when the number of species in the tree
1181 and in the variables were different: this is fixed.
1185 CHANGES IN APE VERSION 1.8-2
1190 o The new function mlphylo() fits a phylogenetic tree by maximum
1191 likelihood from DNA sequences. Its companion function DNAmodel()
1192 is used to define the substitution model which may include
1193 partitioning. There are methods for logLik(), deviance(), and
1194 AIC(), and the summary() method has been extended to display in
1195 a friendly way the results of this model fitting. Currently, the
1196 functionality is limited to estimating the substitution and
1197 associated parameters and computing the likelihood.
1199 o The new function drop1.compar.gee (used as, e.g., drop1(m))
1200 tests for single effects in GEE-based comparative method. A
1201 warning message is printed if there is not enough degrees of
1207 o An error message was sometimes issued by plot.multi.tree(),
1208 though with no consequence.
1212 CHANGES IN APE VERSION 1.8-1
1217 o There is a new plot method for lists of trees (objects of class
1218 "multi.tree"): it calls plot.phylo() internally and is
1219 documented on the same help page.
1224 o A bug was fixed in the C code that analyzes bipartitions: this
1225 has impact on several functions like prop.part, prop.clades,
1226 boot.phylo, or consensus.
1228 o root() did not work correctly when the specified outgroup had
1229 more than one element: this is fixed.
1231 o dist.dna() sometimes returned a warning inappropriately: this
1234 o If the distance object given to nj() had no rownames, nj()
1235 returned a tree with no tip labels: it now returns tips labelled
1236 "1", "2", ..., corresponding to the row numbers.
1241 o nj() has been slightly changed so that tips with a zero distance
1242 are first aggregated with zero-lengthed branches; the usual NJ
1243 procedure is then performed on a distance matrix without 0's.
1247 CHANGES IN APE VERSION 1.8
1252 o The new function chronopl() estimates dates using the penalized
1253 likelihood method by Sanderson (2002; Mol. Biol. Evol., 19:101).
1255 o The new function consensus() calculates the consensus tree of a
1258 o The new function evolve.phylo() simulates the evolution of
1259 continuous characters along a phylogeny under a Brownian model.
1261 o The new plot method for objects of class "ancestral" displays a
1262 tree together with ancestral values, as returned by the above
1265 o The new function as.phylo.formula() returns a phylogeny from a
1266 set of nested taxonomic variables given as a formula.
1268 o The new function read.caic() reads trees in CAIC format.
1270 o The new function tiplabels() allows to add labels to the tips
1271 of a tree using text or plotting symbols in a flexible way.
1273 o The new function unroot() unroots a phylogeny.
1275 o multi2di() has a new option, `random', which specifies whether
1276 to resolve the multichotomies randomly (the default) or not.
1278 o prop.part() now returns an object of class "prop.part" for which
1279 there are print (to display a partition in a more friendly way)
1280 and summary (to extract the numbers) methods.
1282 o plot.phylo() has a new option, `show.tip.label', specifying
1283 whether to print the labels of the tips. The default is TRUE.
1285 o The code of nj() has been replaced by a faster C code: it is now
1286 about 10, 25, and 40 times faster for 50, 100, and 200 taxa,
1289 o write.nexus() now writes whether a tree is rooted or not.
1294 o Two bugs have been fixed in root(): unrooted trees are now
1295 handled corretly, and node labels are now output normally.
1297 o A bug was fixed in phymltest(): the executable couldn't be found
1300 o Three bug have been fixed in ace(): computing the likelihood of
1301 ancestral states of discrete characters failed, custom models
1302 did not work, and the function failed with a null gradient (a
1303 warning message is now returned; this latter bug was also
1304 present in yule.cov() as well and is now fixed).
1306 o pic() hanged out when missing data were present: a message error
1309 o A small bug was fixed in dist.dna() where the gamma correction
1310 was not always correctly dispatched.
1312 o plot.phylo() plotted correctly the root edge only when the tree
1313 was plotted rightwards: this works now for all directions.
1318 o dist.taxo() has been renamed as weight.taxo().
1320 o dist.phylo() has been replaced by the method cophenetic.phylo().
1322 o Various error and warning messages have been improved.
1326 CHANGES IN APE VERSION 1.7
1329 o The new function ace() estimates ancestral character states for
1330 continuous characters (with ML, GLS, and contrasts methods), and
1331 discrete characters (with ML only) for any number of states.
1333 o The new function compar.ou() fits the Ornstein-Uhlenbeck model
1334 of directional evolution for continuous characters. The user
1335 specifies the node(s) of the tree where the character optimum
1338 o The new function is.rooted() tests whether a tree (of class
1341 o The new function rcoal() generates random ultrametric trees with
1342 the possibility to specify the function that generates the
1343 inter-nodes distances.
1345 o The new function mrca() gives for all pairs of tips in a tree
1346 (and optionally nodes too) the most recent common ancestor.
1348 o nodelabels() has a new option `thermo' to plot proportions (up
1349 to three classes) on the nodes of a tree.
1351 o rtree() has been improved: it can now generate rooted or
1352 unrooted trees, and the mathematical function that generates the
1353 branch lengths may be specified by the user. The tip labels may
1354 be given directly in the call to rtree. The limit cases (n = 2,
1355 3) are now handled correctly.
1357 o dist.topo() has a new argument `method' with two choices: "PH85"
1358 for Penny and Henny's method (already available before and now
1359 the default), and "BHV01" for the geometric distance by Billera
1360 et al. (2001, Adv. Appl. Math. 27:733).
1362 o write.tree() has a new option, `digits', which specifies the
1363 number of digits to be printed in the Newick tree. By default
1364 digits = 10. The numbers are now always printed in decimal form
1365 (i.e., 1.0e-1 is now avoided).
1367 o dist.dna() can now compute the raw distances between pairs of
1368 DNA sequences by specifying model = "raw".
1370 o dist.phylo() has a new option `full' to possibly compute the
1371 distances among all tips and nodes of the tree. The default if
1377 o Several bugs were fixed in all.equal.phylo().
1379 o dist.dna() did not handle correctly gaps ("-") in alignments:
1380 they are now considered as missing data.
1382 o rotate() did not work if the tips were not ordered: this is
1385 o mantel.test() returned NA in some special cases: this is fixed
1386 and the function has been improved and is now faster.
1388 o A bug was fixed in diversi.gof() where the calculation of A² was
1391 o cherry() did not work correctly under some OSs (mainly Linux):
1394 o is.binary.tree() has been modified so that it works with both
1395 rooted and unrooted trees.
1397 o The documentation of theta.s() was not correct: this has been
1400 o plot.mst() did not work correctly: this is fixed.
1404 CHANGES IN APE VERSION 1.6
1409 o The new function dist.topo() computes the topological distances
1412 o The new function boot.phylo() performs a bootstrap analysis on
1413 phylogeny estimation.
1415 o The new functions prop.part() and prop.clades() analyse
1416 bipartitions from a series of trees.
1421 o read.GenBank() now uses the EFetch utility of NCBI instead of
1422 the usual Web interface: it is now much faster (e.g., 12 times
1423 faster to retrieve 8 sequences, 37 times for 60 sequences).
1428 o Several bugs were fixed in read.dna().
1430 o Several bugs were fixed in diversi.time().
1432 o is.binary.tree() did not work correctly if the tree has no edge
1433 lengths: this is fixed.
1435 o drop.tip() did not correctly propagated the `node.label' of a
1436 tree: this is fixed.
1440 CHANGES IN APE VERSION 1.5
1445 o Two new functions, as.matching.phylo() and as.phylo.matching(),
1446 convert objects between the classes "phylo" and "matching". The
1447 latter implements the representation of binary trees introduced by
1448 Diaconis and Holmes (1998; PNAS 95:14600). The generic function
1449 as.matching() has been introduced as well.
1451 o Two new functions, multi2di() and di2multi(), allow to resolve
1452 and collapse multichotomies with branches of length zero.
1454 o The new function nuc.div() computes the nucleotide diversity
1455 from a sample a DNA sequences.
1457 o dist.dna() has been completely rewritten with a much faster
1458 (particularly for large data sets) C code. Eight models are
1459 available: JC69, K80, F81, K81, F84, T92, TN93, and GG95 (the
1460 option `method' has been renamed `model'). Computation of variance
1461 is available for all models. A gamma-correction is possible for
1462 JC69, K80, F81, and TN93. There is a new option, pairwise.deletion,
1463 to remove sites with missing data on a pairwise basis. The option
1464 `GCcontent' has been removed.
1466 o read.GenBank() has a new option (species.names) which specifies
1467 whether to return the species names of the organisms in addition
1468 to the accession numbers of the sequences (this is the default
1471 o write.nexus() can now write several trees in the same NEXUS file.
1473 o drop.tip() has a new option `root.edge' that allows to specify the
1474 new root edge if internal branches are trimmed.
1479 o as.phylo.hclust() failed if some labels had parentheses: this
1482 o Several bugs were fixed in all.equal.phylo(). This function now
1483 returns the logical TRUE if the trees are identical but with
1484 different representations (a report was printed previously).
1486 o read.GenBank() did not correctly handle ambiguous base codes:
1492 o birthdeath() now returns an object of class "birthdeath" for
1493 which there is a print method.
1497 CHANGES IN APE VERSION 1.4
1502 o The new function nj() performs phylogeny estimation with the
1503 neighbor-joining method of Saitou and Nei (1987; Mol. Biol.
1506 o The new function which.edge() identifies the edges of a tree
1507 that belong to a group specified as a set of tips.
1509 o The new function as.phylo.phylog() converts an object of class
1510 "phylog" (from the package ade4) into an object of class
1513 o The new function axisPhylo() draws axes on the side of a
1516 o The new function howmanytrees() calculates the number of trees
1517 in different cases and giving a number of tips.
1519 o write.tree() has a new option `multi.line' (TRUE by default) to
1520 write a Newick tree on several lines rather than on a single
1523 o The functionalities of zoom() have been extended. Several
1524 subtrees can be visualized at the same time, and they are marked
1525 on the main tree with colors. The context of the subtrees can be
1526 marked with the option `subtree' (see below).
1528 o drop.tip() has a new option `subtree' (FALSE by default) which
1529 specifies whether to output in the tree how many tips have been
1532 o The arguments of add.scale.bar() have been redefined and have
1533 now default values (see ?add.scale.bar for details). This
1534 function now works even if the plotted tree has no edge length.
1536 o plot.phylo() can now plot radial trees, but this does not take
1537 edge lengths into account.
1539 o In plot.phylo() with `type = "phylogram"', if the values of
1540 `edge.color' and `edge.width' are identical for sister-branches,
1541 they are propagated to the vertical line that link them.
1546 o Repeated calls to as.phylo.hclust() or as.hclust.phylo() made R
1547 crashing. This is fixed.
1549 o In plot.phylo(), the options `edge.color' and `edge.width' are
1550 now properly recycled; their default values are now "black" and
1553 o A bug has been fixed in write.nexus().
1558 o The function node.depth.edgelength() has been removed and
1559 replaced by a C code.
1563 CHANGES IN APE VERSION 1.3-1
1568 o The new function nodelabels() allows to add labels to the nodes
1569 of a tree using text or plotting symbols in a flexible way.
1571 o In plot.phylo() the arguments `x.lim' and `y.lim' can now be two
1572 numeric values specifying the lower and upper limits on the x-
1573 and y-axes. This allows to leave some space on any side of the
1574 tree. If a single value is given, this is taken as the upper
1579 CHANGES IN APE VERSION 1.3
1584 o The new function phymltest() calls the software PHYML and fits
1585 28 models of DNA sequence evolution. There are a print method to
1586 display likelihood and AIC values, a summary method to compute
1587 the hierarchical likelihood ratio tests, and a plot method to
1588 display graphically the AIC values of each model.
1590 o The new function yule.cov() fits the Yule model with covariates,
1591 a model where the speciation rate is affected by several species
1592 traits through a generalized linear model. The parameters are
1593 estimated by maximum likelihood.
1595 o Three new functions, corBrownian(), corGrafen(), and
1596 corMartins(), compute the expected correlation structures among
1597 species given a phylogeny under different models of evolution.
1598 These can be used for GLS comparative phylogenetic methods (see
1599 the examples). There are coef() and corMatrix() methods and an
1600 Initialize.corPhyl() function associated.
1602 o The new function compar.cheverud() implements Cheverud et al.'s
1603 (1985; Evolution 39:1335) phylogenetic comparative method.
1605 o The new function varcomp() estimates variance components; it has
1608 o Two new functions, panel.superpose.correlogram() and
1609 plot.correlogramList(), allow to plot several phylogenetic
1612 o The new function node.leafnumber() computes the number of leaves
1613 of a subtree defined by a particular node.
1615 o The new function node.sons() gets all tags of son nodes from a
1618 o The new function compute.brlen() computes the branch lengths of
1619 a tree according to a specified method.
1621 o plot.phylo() has three new options: "cex" controls the size of
1622 the (tip and node) labels (thus it is no more needed to change
1623 the global graphical parameter), "direction" which allows to
1624 plot the tree rightwards, leftwards, upwards, or downwards, and
1625 "y.lim" which sets the upper limit on the y-axis.
1630 o Some functions which try to match tip labels and names of
1631 additional data (e.g. vector) are likely to fail if there are
1632 typing or syntax errors. If both series of names do not perfectly
1633 match, they are ignored and a warning message is now issued.
1634 These functions are bd.ext, compar.gee, pic. Their help pages
1635 have been clarified on this point.
1639 CHANGES IN APE VERSION 1.2-7
1644 o The new function root() reroots a phylogenetic tree with respect
1645 to a specified outgroup.
1647 o The new function rotate() rotates an internal branch of a tree.
1649 o In plot.phylo(), the new argument "lab4ut" (labels for unrooted
1650 trees) controls the display of the tip labels in unrooted trees.
1651 This display has been greatly improved: the tip labels are now not
1652 expected to overlap with the tree (particularly if lab4ut =
1653 "axial"). In all cases, combining appropriate values of "lab4ut"
1654 and the font size (via "par(cex = )") should result in readable
1655 unrooted trees. See ?plot.phylo for some examples.
1657 o In drop.tip(), the argument `tip' can now be numeric or character.
1662 o drop.tip() did not work correctly with trees with no branch
1663 lengths: this is fixed.
1665 o A bug in plot.phylo(..., type = "unrooted") made some trees being
1666 plotted with some line crossings: this is now fixed.
1670 CHANGES IN APE VERSION 1.2-6
1675 o Six new functions (Moran.I, correlogram.formula, discrete.dist,
1676 correlogram.phylo, dist.taxo, plot.correlogram) have been added
1677 to implement comparative methods with an autocorrelation approach.
1679 o A new data set describing some life history traits of Carnivores
1685 o A fix was made on mcmc.popsize() to conform to R 2.0.0.
1690 o When plotting a tree with plot.phylo(), the new default of the
1691 option `label.offset' is now 0, so the labels are always visible.
1695 CHANGES IN APE VERSION 1.2-5
1700 o The new function bd.ext() fits a birth-death model with combined
1701 phylogenetic and taxonomic data, and estimates the corresponding
1702 speciation and extinction rates.
1707 o The package gee is no more required by ape but only suggested
1708 since only the function compar.gee() calls gee.
1712 CHANGES IN APE VERSION 1.2-4
1717 o Four new functions (mcmc.popsize, extract.popsize, plot.popsize,
1718 and lines.popsize) implementing a new approach for inferring the
1719 demographic history from genealogies using a reversible jump
1720 MCMC have been introduced.
1722 o The unit of time in the skyline plot and in the new plots can
1723 now be chosen to be actual years, rather than substitutions.
1727 CHANGES IN APE VERSION 1.2-3
1732 o The new function rtree() generates a random binary tree with or
1733 without branch lengths.
1735 o Two new functions for drawing lineages-through-time (LTT) plots
1736 are provided: ltt.lines() adds a LTT curve to an existing plot,
1737 and mltt.plot() does a multiple LTT plot giving several trees as
1738 arguments (see `?ltt.plot' for details).
1743 o Some taxon names made R crashing when calling as.phylo.hclust():
1746 o dist.dna() returned an error with two identical DNA sequences
1747 (only using the Jukes-Cantor method returned 0): this is fixed.
1752 o The function dist.phylo() has been re-written using a different
1753 algorithm: it is now about four times faster.
1755 o The code of branching.times() has been improved: it is now about
1760 CHANGES IN APE VERSION 1.2-2
1765 o The new function seg.sites() finds the segregating sites in a
1766 sample of DNA sequences.
1771 o A bug introduced in read.tree() and in read.nexus() with version
1774 o A few errors were corrected and a few examples were added in the
1779 CHANGES IN APE VERSION 1.2-1
1784 o plot.phylo() can now draw the edge of the root of a tree if it
1785 has one (see the new option `root.edge', its default is FALSE).
1790 o A bug was fixed in read.nexus(): files with semicolons inside
1791 comment blocks were not read correctly.
1793 o The behaviour of read.tree() and read.nexus() was corrected so
1794 that tree files with badly represented root edges (e.g., with
1795 an extra pair of parentheses, see the help pages for details)
1796 are now correctly represented in the object of class "phylo";
1797 a warning message is now issued.
1801 CHANGES IN APE VERSION 1.2
1806 o plot.phylo() has been completely re-written and offers several
1807 new functionalities. Three types of trees can now be drawn:
1808 phylogram (as previously), cladogram, and unrooted tree; in
1809 all three types the branch lengths can be drawn using the edge
1810 lengths of the phylogeny or not (e.g., if the latter is absent).
1811 The vertical position of the nodes can be adjusted with two
1812 choices (see option `node.pos'). The code has been re-structured,
1813 and two new functions (potentially useful for developpers) are
1814 documented separately: node.depth.edgelength() and node.depth();
1815 see the respective help pages for details.
1817 o The new function zoom() allows to explore very large trees by
1818 focusing on a small portion of it.
1820 o The new function yule() fits by maximum likelihood the Yule model
1821 (birth-only process) to a phylogenetic tree.
1823 o Support for writing DNA sequences in FASTA format has been
1824 introduced in write.dna() (support for reading sequences in
1825 this format was introduced in read.dna() in version 1.1-2).
1826 The function has been completely re-written, fixing some bugs
1827 (see below); the default behaviour is no more to display the
1828 sequences on the standard output. Several options have been
1829 introduced to control the sequence printing in a flexible
1830 way. The help page has been extended.
1832 o A new data set is included: a supertree of bats in NEXUS format.
1837 o In theta.s(), the default of the option `variance' has
1838 been changed to `FALSE' (as was indicated in the help page).
1840 o Several bugs were fixed in the code of all.equal.phylo().
1842 o Several bugs were fixed in write.dna(), particularly this
1843 function did not work with `format = "interleaved"'.
1845 o Various errors were corrected in the help pages.
1850 o The argument names of as.hclust.phylo() have been changed
1851 from "(phy)" to "(x, ...)" to conform to the definition of
1852 the corresponding generic function.
1854 o gamma.stat() has been renamed gammaStat() to avoid confusion
1855 since gamma() is a generic function.
1859 CHANGES IN APE VERSION 1.1-3
1864 o base.freq() previously did not return a value of 0 for
1865 bases absent in the data (e.g., a vector of length 3 was
1866 returned if one base was absent). This is now fixed (a
1867 vector of length 4 is always returned).
1869 o Several bugs were fixed in read.nexus(), including that this
1870 function did not work in this absence of a "TRANSLATE"
1871 command in the NEXUS file, and that the commands were
1876 CHANGES IN APE VERSION 1.1-2
1881 o The Tamura and Nei (1993) model of DNA distance is now implemented
1882 in dist.dna(): five models are now available in this function.
1884 o A new data set is included: a set of 15 sequences of the
1885 cytochrome b mitochondrial gene of the woodmouse (Apodemus
1891 o A bug in read.nexus() was fixed.
1893 o read.dna() previously did not work correctly in most cases.
1894 The function has been completely re-written and its help page
1895 has been considerably extended (see ?read.dna for details).
1896 Underscores (_) in taxon names are no more replaced with
1897 spaces (this behaviour was undocumented).
1899 o A bug was fixed in write.dna().
1903 CHANGES IN APE VERSION 1.1-1
1908 o A bug in read.tree() introduced in APE 1.1 was fixed.
1910 o A bug in compar.gee() resulted in an error when trying to fit
1911 a model with `family = "binomial"'. This is now fixed.
1915 CHANGES IN APE VERSION 1.1
1920 o The Klastorin (1982) method as suggested by Misawa and Tajima
1921 (2000, Mol. Biol. Evol. 17:1879-1884) for classifying genes
1922 on the basis of phylogenetic trees has been implemented (see
1923 the function klastorin()).
1925 o Functions have been added to convert APE's "phylo" objects in
1926 "hclust" cluster objects and vice versa (see the help page of
1927 as.phylo for details).
1929 o Three new functions, ratogram(), chronogram() and NPRS.criterion(),
1930 are introduced for the estimation of absolute evolutionary rates
1931 (ratogram) and dated clock-like trees (chronogram) from
1932 phylogenetic trees using the non-parametric rate smoothing approach
1933 by MJ Sanderson (1997, Mol. Biol. Evol. 14:1218-1231).
1935 o A summary method is now provided printing a summary information on a
1936 phylogenetic tree with, for instance, `summary(tree)'.
1938 o The behaviour of read.tree() was changed so that all spaces and
1939 tabulations in tree files are now ignored. Consequently, spaces in tip
1940 labels are no more allowed. Another side effect is that read.nexus()
1941 now does not replace the underscores (_) in tip labels with spaces
1942 (this behaviour was undocumented).
1944 o The function plot.phylo() has a new option (`underscore') which
1945 specifies whether the underscores in tip labels should be written on
1946 the plot as such or replaced with spaces (the default).
1948 o The function birthdeath() now computes 95% confidence intervals of
1949 the estimated parameters using profile likelihood.
1951 o Three new data sets are included: a gene tree estimated from 36
1952 landplant rbcL sequences, a gene tree estimated from 32 opsin
1953 sequences, and a gene tree for 50 BRCA1 mammalian sequences.
1958 o A bug was fixed in dist.gene() where nothing was returned.
1960 o A bug in plot.mst() was fixed.
1962 o A bug in vcv.phylo() resulted in false correlations when the
1963 option `cor = TRUE' was used (now fixed).
1967 CHANGES IN APE VERSION 1.0
1972 o Two new functions, read.dna() and write.dna(), read/write in a file
1973 DNA sequences in interleaved or in sequential format.
1975 o Two new functions, read.nexus() and write.nexus(), read/write trees
1978 o The new function bind.tree() allows to bind two trees together,
1979 possibly handling root edges to give internal branches.
1981 o The new function drop.tip() removes the tips in a phylogenetic tree,
1982 and trims (or not) the corresponding internal branches.
1984 o The new function is.ultrametric() tests if a tree is ultrametric.
1986 o The function plot.phylo() has more functionalities such as drawing the
1987 branches with different colours and/or different widths, showing the
1988 node labels, controling the position and font of the labels, rotating
1989 the labels, and controling the space around the plot.
1991 o The function read.tree() can now read trees with no branch length,
1992 such as "(a,b),c);". Consequently, the element `edge.length' in
1993 objects of class "phylo" is now optional.
1995 o The function write.tree() has a new default behaviour: if the default
1996 for the option `file' is used (i.e. file = ""), then a variable of
1997 mode character containing the tree in Newick format is returned which
1998 can thus be assigned (e.g., tree <- write.tree(phy)).
2000 o The function read.tree() has a new argument `text' which allows
2001 to read the tree in a variable of mode character.
2003 o A new data set is included: the phylogenetic relationships among
2004 the orders of birds from Sibley and Ahlquist (1990).
2008 CHANGES IN APE VERSION 0.2-1
2013 o Several bugs were fixed in the help pages.
2017 CHANGES IN APE VERSION 0.2
2022 o The function write.tree() writes phylogenetic trees (objects of class
2023 "phylo") in an ASCII file using the Newick parenthetic format.
2025 o The function birthdeath() fits a birth-death model to branching times
2026 by maximum likelihood, and estimates the corresponding speciation and
2029 o The function scale.bar() adds a scale bar to a plot of a phylogenetic
2032 o The function is.binary.tree() tests whether a phylogeny is binary.
2034 o Two generic functions, coalescent.intervals() and collapsed.intervals(),
2035 as well as some methods are introduced.
2037 o Several functions, including some generics and methods, for computing
2038 skyline plot estimates (classic and generalized) of effective
2039 population size through time are introduced and replace the function
2040 skyline.plot() in version 0.1.
2042 o Two data sets are now included: the phylogenetic relationships among
2043 the families of birds from Sibley and Ahlquist (1990), and an
2044 estimated clock-like phylogeny of HIV sequences sampled in the
2045 Democratic Republic of Congo.
2048 DEPRECATED & DEFUNCT
2050 o The function skyline.plot() in ape 0.1 has been deprecated and
2051 replaced by more elaborate functions (see above).
2056 o Two important bugs were fixed in plot.phylo(): phylogenies with
2057 multichotomies not at the root or not with only terminal branches,
2058 and phylogenies with a single node (i.e. only terminal branches)
2059 did not plot. These trees should be plotted correctly now.
2061 o Several bugs were fixed in diversi.time() in the computation of
2064 o Various errors were corrected in the help pages.
