I am member of the core development teams of
an open source implementation of the S language. The R core team is a group of individuals located in Austria, Canada, Denmark, England, Italy, New Zealand, Switzerland, and the U.S.A., who collectively develop the R base distribution. To support further development of R and open source statistical software in general we have created the R Foundation, where I currently serve as secretary general. Kurt Hornik and I maintain the Comprehensive R Archive Network (CRAN), where you find R itself, more than 1200 extension packages (contributed by users worldwide), additional docmentation and other tools that are useful in combination with R.
an open source software framework that will assist biologists and statisticians working in bioinformatics, with primary emphasis on inference using DNA microarrays.
a platform for exchange and development of new ideas for computing with data.
