[R-sig-genetics] r-genetics and galaxy

We have some tools that I think have been put into an R package but not sent to CRAN.  They implement the methods in http://onlinelibrary.wiley.com/resolve/doi/pdf?DOI=10.1002/gepi.20516
This has been used for data sets up to 16000 people x 1M SNPs.

I will check to see the current status of the code -- the plan is to refactor it and combine with our analysis code for a Bioconductor package.
