Hi, I have a package in development for fitting additive tree models to data. Basically the core of the package is and R interface to TRex, Vladimir Makarenkov has givien me permission to release this on CRAN or Bioconductor under gpl. Besides the TRex functions for least squares fitting of trees and reticulograms, I am adding functions for plotting, rooting trees, a tree class that extends the graph class and some more general stuff for additive trees were one has replicate distance matrices as often occurs in psychology. I would like to add tools for maximum likelihood estimation, but I am not sure of the phyllip license and I don't want to appropriate code if it is not kosher. I am still working on some of the tree display algorithms which is going slow since I hold a job in the day that is not opensource friendly. If anyone is interested in codeveloping I am happy to share the load :) Nicholas

See the "ape" package in CRAN which does some of this stuff as well... best, -tony -- A.J.

Nicholas, You can also look into trexml http://jcsmr.anu.edu.au/dicb/humgen/marty/trexml/trexml.man.html which does use Felsensteins' program, I don't think you have to worry about keeping away from Felsenstein's code, his copyright notice is pretty clear, he doesn't want others to use it and then sell their software, as detailed also on marty Wolf's trexml page. I think it would be most useful to have a ml implementation in R, we are developping packages that compute distances between trees as they are output by phylip (in Newick format), we have developed our own treeclass for this, I have also developed various other interfaces to phylip, but would actually like a more ``R-based'' approach (ape does not do any tree estimation either). Please make more precise what kind of help you would like, I would be all for using trexml, what do you think.

Hi, Just took a quick look at the code and it doesn't llok like it would be too difficult to port since it is a command line interface. I don't have a problem using it, though I will email the authors and see about getting "better" license on it. Better meaning something more established with better legal ramifications such as the mit license. Licensing is a pain but it is important to respect the copyright and intent of the authors. I agree about having an R interface to the phylogenetic estimation routines. Especially as Bioconductor gets better sequence processing facilities. I would be happy to include some of your implementations in the package and work you guys in as co-authors if you would like to contribute.
