+ CHANGES IN APE VERSION 2.6-1
+
+
+BUG FIXES
+
+ o as.hclust.phylo() failed with trees with node labels (thanks to
+ Filipe Vieira for the fix).
+
+
+
+ CHANGES IN APE VERSION 2.6
+
+
+NEW FEATURES
+
+ o The new functions rlineage and rbdtree simulate phylogenies under
+ any user-defined time-dependent speciation-extinction model. They
+ use continuous time algorithms.
+
+ o The new function drop.fossil removes the extinct species from a
+ phylogeny.
+
+ o The new function bd.time fits a user-defined time-dependent
+ birth-death model. It is a generalization of yule.time() taking
+ extinction into account.
+
+ o The new function MPR does most parsimonious reconstruction of
+ discrete characters.
+
+ o The new function Ftab computes the contingency table of base
+ frequencies from a pair of sequences.
+
+ o There is now an 'as.list' method for the class "DNAbin".
+
+ o dist.dna() can compute the number of transitions or transversions
+ with the option model = "Ts" or model = "Tv", respectively.
+
+ o [node|tip|edge]labels() gain three options with default values to
+ control the aspect of thermometers: horiz = TRUE, width = NULL,
+ and height = NULL.
+
+ o compar.gee() has been improved with the new option 'corStruct' as an
+ alternative to 'phy' to specify the correlation structure, and
+ calculation of the QIC (Pan 2001, Biometrics). The display of the
+ results has also been improved.
+
+ o read.GenBank() has a new option 'gene.names' to return the name of
+ the gene (FALSE by default).
+
+
+BUG FIXES
+
+ o extract.clade() sometimes shuffled the tip labels.
+
+ o plot.phylo(type = "unrooted") did not force asp = 1 (thanks to Klaus
+ Schliep for the fix)
+
+ o dist.dna(model = "logdet") used to divide distances by 4. The
+ documentation has been clarified on the formulae used.
+
+
+OTHER CHANGES
+
+ o rTraitCont(model = "OU") has an option 'linear = TRUE' to possibly
+ change the parameterisation (see ?rTraitCont for details).
+
+ o pic() now returns a vector with the node labels of the tree (if
+ available) as names.
+
+ o write.tree() and read.tree() have been substantially thanks to
+ contributions by Klaus Schliep.
+
+
+
+ CHANGES IN APE VERSION 2.5-3
+
+
+NEW FEATURES
+
+ o The new function mixedFontLabel helps to make labels with bits of
+ text to be plotted in different fonts.
+
+ o There are now replacement operators for [, [[, and $ for the class
+ "multiPhylo" (i.e., TREES[11:20] <- rmtree(10, 100)). They possibly
+ check that the tip labels are the same in all trees.
+
+ o Objects of class "multiPhylo" can be built with c(): there are
+ methods for the classes "phylo" and "multiPhylo".
+
+ o The internal functions .compressTipLabel and .uncompressTipLabel are
+ now documented.
+
+
+BUG FIXES
+
+ o bind.tree(x, y, where, position = 0) did not work correctly if 'y'
+ was a single-edge tree and 'where' was a tip.
+
+ o rTraitCont() did not use the square-root of branch lengths when
+ simulating a Brownian motion model.
+
+
+
+ CHANGES IN APE VERSION 2.5-2
+
+
+NEW FEATURES
+
+ o There is now a print method for results from ace().
+
+ o There is a labels() method for objects of class "DNAbin".
+
+ o read.dna() has a new option 'as.matrix' to possibly force sequences
+ in a FASTA file to be stored in a matrix (see ?read.dna for details).
+
+
+BUG FIXES
+
+ o as.phylo.hclust() used to multiply edge lengths by 2.
+
+ o A minor bug was fixed in rTraitDisc().
+
+ o ace() sometimes failed (parameter value was NaN and the optimisation
+ failed).
+
+
+DEPRECATED & DEFUNCT
+
+ o evolve.phylo() and plot.ancestral() have been removed.
+
+ o chronogram(), ratogram(), and NPRS.criterion() have been removed.
+
+
+OTHER CHANGES
+
+ o nj() has been improved and is now about 30% faster.
+
+ o The default option 'drop' of [.DNAbin has been changed to FALSE to
+ avoid dropping rownames when selecting a single sequence.
+
+ o print.DNAbin() has been changed to summary.DNAbin() which has been
+ removed.
+
+
+
+ CHANGES IN APE VERSION 2.5-1
+
+
+NEW FEATURES
+
+ o The new function stree generates trees with regular shapes.
+
+ o It is now possible to bind two trees with x + y (see ?bind.tree for
+ details).
+
+ o drop.tip(), extract.clade(), root(), and bind.tree() now have an
+ 'interactive' option to make the operation on a plotted tree.
+
+ o cophyloplot() gains two new arguments 'lwd' and 'lty' for the
+ association links; they are recycled like 'col' (which wasn't before).
+
+
+BUG FIXES
+
+ o rTraitDisc() did not use its 'freq' argument correctly (it was
+ multiplied with the rate matrix column-wise instead of row-wise).
+
+ o [node|tip|edge]labels(thermo = ) used to draw empty thermometers
+ with NA values. Nothing is drawn now like with 'text' or 'pch'.
+ The same bug occurred with the 'pie' option.
+
+ o A bug was fixed in compar.ou() and the help page was clarified.
+
+ o bind.tree() has been rewritten fixing several bugs and making it
+ more efficient.
+
+ o plot.phylo(type = "p") sometimes failed to colour correctly the
+ vertical lines representing the nodes.
+
+ o plot.phylo(direction = "l", x.lim = 30) failed to plot the branches
+ in the correct direction though the tip labels were displayed
+ correctly.
+
+
+OTHER CHANGES
+
+ o The c, cbind, and rbind methods for "DNAbin" objetcs now check that
+ the sequences are correctly stored (in a list for c, in a matrix
+ for the two other functions).
+
+
+
+ CHANGES IN APE VERSION 2.5
+
+
+NEW FEATURES
+
+ o The new function parafit by Pierre Legendre tests for the
+ coevolution between hosts and parasites. It has a companion
+ function, pcoa, that does principal coordinate decomposition.
+ The latter has a biplot method.
+
+ o The new function lmorigin by Pierre Legendre performs multiple
+ regression through the origin with testing by permutation.
+
+ o The new functions rTraitCont and rTraitDisc simulate continuous and
+ discrete traits under a wide range of evolutionary models.
+
+ o The new function delta.plot does a delta plot following Holland et
+ al. (2002, Mol. Biol. Evol. 12:2051).
+
+ o The new function edges draws additional branches between any nodes
+ and/or tips on a plotted tree.
+
+ o The new function fancyarrows enhances arrows from graphics with
+ triangle and harpoon heads; it can be called from edges().
+
+ o add.scale.bar() has a new option 'ask' to draw interactively.
+
+ o The branch length score replaces the geodesic distance in dist.topo.
+
+ o Three new data sets are included: the gopher-lice data (gopher.D),
+ SO2 air pollution in 41 US cities (lmorigin.ex1, from Sokal &
+ Rohlf 1995), and some host-parasite specificity data
+ (lmorigin.ex2, from Legendre & Desdevises 2009).
+
+
+BUG FIXES
+
+ o add.scale.bar() drew the bar outside the plotting region with the
+ default options with unrooted or radial trees.
+
+ o dist.topo() made R stuck when the trees had different sizes (thanks
+ to Otto Cordero for the fix).
+
+
+OTHER CHANGES
+
+ o The geodesic distance has been replaced by the branch length score
+ in dist.topo().
+
+
+
+ CHANGES IN APE VERSION 2.4-1
+
+
+NEW FEATURES
+
+ o rtree() and rcoal() now accept a numeric vector for the 'br'
+ argument.
+
+ o vcv() is a new generic function with methods for the classes "phylo"
+ and "corPhyl" so that it is possible to calculate the var-cov matrix
+ for "transformation models". vcv.phylo() can still be used for trees
+ of class "phylo"; its argument 'cor' has been renamed 'corr'.
+
+
+BUG FIXES
+
+ o bind.tree() failed when 'y' had no root edge.
+
+ o read.nexus() shuffled tip labels when the trees have no branch
+ lengths and there is a TRANSLATE block.
+
+ o read.nexus() does not try to translate node labels if there is a
+ translation table in the NEXUS file. See ?read.nexus for a
+ clarification on this behaviour.
+
+ o plot.multiPhylo() crashed R when plotting a list of trees with
+ compressed tip labels.
+
+ o write.nexus() did not translate the taxa names when asked for.
+
+ o plot.phylo(type = "fan") did not rotate the tip labels correctly
+ when the tree has branch lengths.
+
+ o ace(type = "continuous", method = "ML") now avoids sigma² being
+ negative (which resulted in an error).
+
+ o nj() crashed with NA/NaN in the distance matrix: an error in now
+ returned.
+
+
+
+ CHANGES IN APE VERSION 2.4
+
+
+NEW FEATURES
+
+ o base.freq() has a new option 'freq' to return the counts; the
+ default is still to return the proportions.
+
+
+BUG FIXES
+
+ o seg.sites() did not handle ambiguous nucleotides correctly: they
+ are now ignored.
+
+ o plot(phy, root.edge = TRUE) failed if there was no $root.edge in
+ the tree: the argument is now ignored.
+
+ o add.scale.bar() failed when 'x' and 'y' were given (thanks to Janet
+ Young for the fix).
+
+
+OTHER CHANGES
+
+ o Trying to plot a tree with a single tip now returns NULL with a
+ warning (it returned an error previously).
+
+ o The way lines representing nodes are coloured in phylograms has
+ been modified (as well as their widths and types) following some
+ users' request; this is only for dichotomous nodes.
+
+ o The argument 'adj' in [node][tip][edge]labels() now works when
+ using 'pie' or 'thermo'.
+
+ o A more informative message error is now returned by dist.dna() when
+ 'model' is badly specified (partial matching of this argument is
+ done now).
+
+ o Deprecated functions are now listed in a help page: see
+ help("ape-defunct") with the quotes.
+
+
+DEPRECATED & DEFUNCT
+
+ o The functions heterozygosity, nuc.div, theta.h, theta.k and
+ theta.s have been moved from ape to pegas.
+
+ o The functions mlphylo, DNAmodel and sh.test have been removed.
+
+
+
+ CHANGES IN APE VERSION 2.3-3
+
+
+BUG FIXES
+
+ o add.scale.bar() always drew a horizontal bar.
+
+ o zoom() shuffled tips with unrooted trees.
+
+ o write.nexus() failed to write correctly trees with a "TipLabel"
+ attribute.
+
+ o rcoal() failed to compute branch lengths with very large n.
+
+ o A small bug was fixed in compar.cheverud() (thanks to Michael
+ Phelan for the fix).
+
+ o seg.sites() failed when passing a vector.
+
+ o drop.tip() sometimes shuffled tip labels.
+
+ o root() shuffled node labels with 'resolve.root = TRUE'.
+
+
+
+ CHANGES IN APE VERSION 2.3-2
+
+
+BUG FIXES
+
+ o all.equal.phylo() did not compare unrooted trees correctly.
+
+ o dist.topo(... method = "PH85") did not treat unrooted trees
+ correctly (thanks to Tim Wallstrom for the fix).
+
+ o root() sometimes failed to test for the monophyly of the
+ outgroup correctly.
+
+ o extract.clade() sometimes included too many edges.
+
+ o vcv.phylo() did not work correctly when the tree is in
+ "pruningwise" order.
+
+ o nj() did not handle correctly distance matrices with many 0's.
+ The code has also been significantly improved: 7, 70, 160 times
+ faster with n = 100, 500, 1000, respectively.
+
+
+
+ CHANGES IN APE VERSION 2.3-1
+
+
+NEW FEATURES
+
+ o The new function is.monophyletic tests the monophyly of a group.
+
+ o There is now a c() method for lists of class "DNAbin".
+
+ o yule.cov() now fits the null model, and its help page has been
+ corrected with respect to this change.
+
+ o drop.tip() has a new option 'rooted' to force (or not) a tree
+ to be treated as (un)rooted.
+
+
+BUG FIXES
+
+ o dist.gene() failed on most occasions with the default
+ pairwise.deletion = FALSE.
+
+ o read.tree() failed to read correctly the tree name(s).
+
+ o boot.phylo() now treats correctly data frames.
+
+ o del.gaps() did not copy the rownames of a matrix.
+
+ o A small bug was fixed in CDAM.global().
+
+ o ace() failed with large data sets. Thanks to Rich FitzJohn for
+ the fix. With other improvements, this function is now about 6
+ times faster.
+
+ o write.tree() failed with objects of class "multiPhylo".
+
+ o drop.tip(, subtree = TRUE) sometimes shuffled tip labels.
+
+
+OTHER CHANGES
+
+ o [.multiPhylo and [.DNAbin now respect the original class.
+
+ o Instances of the form class(phy) == "phylo" have been replaced
+ by inherits(phy, "phylo").
+
+ o rcoal() is now faster.
+
+
+DEPRECATED & DEFUNCT
+
+ o klastorin() has been removed.
+
