Rgedit is a plug-in for gedit (the standard Gnome editor) which transforms it into a light-weight IDE for the statistical environment R. It is aimed at advanced/professional users of R on Linux. It is released under GPLv3 and is written in Python and PyGTK; for more details please see its page on sourceforge.net: http://sourceforge.net/projects/rgedit/

GenLangCorrV4: is the software platform I developed to run simulations of various types of genetically biased language change and evolution, reported in

Dediu, D.  (2008). The role of genetic biases in shaping the correlations between languages and genes. Journal of Theoretical Biology, 254(2), 400-407. and

Dediu, D.  (2009). Genetic biasing through cultural transmission: Do simple Bayesian models of language evolution generalize? Journal of Theoretical Biology, 259, 552-561.

For details please see these two papers as well as the ReadMe.txt included with the source code here. The program is released under GPLv3, is written in C++ and runs on *nix.

BayesLang is a Bayesian phylogeny inference program designed for typological linguistic data. It was designed and written in order to study the stability of typological features but can be used for other goals as well (e.g., the inference of ancestral states):

Dediu, D.  (2010). A Bayesian phylogenetic approach to estimating the stability of linguistic features and the genetic biasing of tone. Proc. Royal Soc. B, doi:10.1098/rspb.2010.1595.

It implements a standard Bayesian phylogeny inference algorithm through a multi-threaded Metropolis-Coupled Markov Chain Monte Carlo, with each chain running in a different thread (or CPU/core on multi-CPU/multi-core machines), with the number of hot chains specified by the user. More information can be found in the cited paper and especially in the accompanying Electronic Supplementary Material as well as the included ReadMe.txt file.

The archive contains the full source code and the 4 primary datasets used in the cited paper in the customized Nexus format recognized by the program. The program is released under GPLv3, is written in C++ and runs on *nix and Windows. Please note that it is intended as a platform for developing and testing new ideas rather than a finished product ready for daily use!
