Analysis of Phylogenetics and Evolution
ape is a package written in R for the analysis of phylogenetics and evolution. It is reasonably used within the community of evolutionary biologists for data analysis and as a framework for the development of new analytical methods. Since 2003, ape has been cited over 1000 times, and 81 R packages depending on ape have been released on CRAN.
pegas is a package for the analysis of population and evolutionary genetics; it is a companion package of ape. To know more about pegas, please visit its page on this site.
coalescentMCMC is a new package for coalescent analysis. Since version 0.4, this package has been considerably improved. Several models of temporal change of Θ are available and can be compared with log-likelihood or information criteria (AIC, BIC, DIC). Running the chains is very flexible and can be managed easily to run them successively, in parallel, or in interaction. The outputs are analysed with the package coda. So all analyses (data preparation, running the chains, convergence diagnostics, parameter estimation, model comparison, …) are done in the same environment! Computing times are reasonably short. The package comes with two vignettes giving details on how to run these analyses.
[2013-12-04] coalescentMCMC 0.4 has been released. This is an(other) important update: see the above description of the package.
[2013-10-27] coalescentMCMC 0.3 has been released. This is an important update: the MCMC algorithm has been carefully checked and is much faster. It is now possible to fit a time-dependent coalescent model. The vignette has been updated with a (almost) complete analysis.
[2013-10-08] pegas 0.5 has been released. Plot of haplotype networks has been improved (see the new function haploFreq). The new function theta.msat calculates THETA using micro-satellites.
[2013-10-01] ape 3.0-11 has been released. This mainly fixes some bugs.
[2013-09-10] ape 3.0-10 has been released. This includes important internal recoding. The new function rotateConstr rotates internal branches given a constraint on the order of the tips. The long-lasting bug plot(phy, main = "A title...") has been fixed.
[2013-07-19] coalescentMCMC 0.2 has been released. The MC code has been completely rewritten. The output is now analysed with the package coda.
[2013-07-19] ape 3.0-9 has been released. This mainly fixes bugs.
[2013-06-06] pegas 0.4-5 has been released.
[2013-04-02] ape 3.0-8 has been released. This includes the new function ewLasso testing whether an incomplete distance matrix uniquely determines the edge weights of an unrooted topology. Some bugs in read.dna(, "fasta") have been fixed.
[2013-01-23] pegas 0.4-4 has been released. This includes a new code for minimum spanning tree, a new estimator of THETA, and some bug fixes.
[2013-01-21] ape 3.0-7 has been released. This includes a new function for molecular dating by PL and ML (chronos). Plotting circular trees has also been improved. Reading FASTA files is much faster and more efficient.
[2012-10-20] ape 3.0-6 has been released. This includes several important internal changes to make ape faster and more stable.
[2012-10-08] The first version of coalescentMCMC has been released.
[2012-08-01] ape 3.0-5 has been released. This includes an improved ace in cases where SEs cannot be computed.
[2012-07-31] pegas 0.4-3 has been released. This fixes some internal code.
[2012-06-13] ape 3.0-4 has been released. This includes an improved read.dna to read Phylip files, and a more stable and faster bionj.
[2012-04-24] pegas 0.4-2 has been released. This fixes a bug in amova where the P-value of the highest level was not correctly computed.
[2012-04-24] ape 3.0-3 has been released. This fixes a bug in birthdeath.
[2012-04-05] ape 3.0-2 has been released. This fixes a number of bugs and introduces the new function alex (alignment explorator).
[2012-03-15] With the publication of the second edition of APER, its page is under renovation with a list of errata. More soon.
[2012-02-17] ape 3.0-1 has been released. This notably fixes the bug in read.GenBank resulting from a change on NCBI.
[2012-02-01] Since the release of R 2.14.0, I recommend to install ape with "byte-compile" for a substantial increase in performance. This is not the default; for instance under Linux:
R CMD INSTALL --byte-compile ape_3.0-2.tar.gzSee the manual "R Installation and Administration" (sect. 6.3.5).
The SVN repository for ape ?
This is the repository with the last sources of ape. It is regularly updated, so that bug fixes can be followed-up before the next release.
This is the "R special interest group on phylogenetic and comparative methods and analyses" mailing list (thanks to the effort of people in NESCent).
