Dear Steven, There are lots of factor analysis packages in R, but it sounds from the below like you want something that can handle sequences too. Have you tried looking in Bioconductor:
http://www.bioconductor.org/ Alternately, the genetics and phylogenetics views in CRAN may have what you want: http://cran.r-project.org/web/views/Genetics.html http://cran.r-project.org/web/views/Phylogenetics.html Best, Amy On Tue, May 25, 2010 at 11:00 AM, <r-sig-epi-requ...@stat.math.ethz.ch>wrote: > Send R-sig-Epi mailing list submissions to > r-sig-epi@stat.math.ethz.ch > > To subscribe or unsubscribe via the World Wide Web, visit > https://stat.ethz.ch/mailman/listinfo/r-sig-epi > or, via email, send a message with subject or body 'help' to > r-sig-epi-requ...@stat.math.ethz.ch > > You can reach the person managing the list at > r-sig-epi-ow...@stat.math.ethz.ch > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of R-sig-Epi digest..." > > > Today's Topics: > > 1.
