Hello Gordon,

Thanks a lot for your reply.

How can I upgrade to the latest version of edge R? I have checked on  the
list and it looks like i need version 2.99.3. However, the one you provide
at http://www.bioconductor.org/packages/2.10/bioc/html/edgeR.html is
edgeR_2.6.12. How can I get the needed version?

Thanks a lot for your help.
