[BioC] limma for R 2.6

[Martin Morgan]

Hi Tiandao --

I'm guess that you updated R but not your Bioconductor packages --
please provide sessionInfo() in all posts! There are instructions for
updating packages on the Bioconductor web site

http://www.bioconductor.org/docs/install-howto.html

at the bottom of the page:

source("http://bioconductor.org/biocLite.R")
biocLite("Biobase")
library(Biobase)
repos <- biocReposList()
update.packages(repos=repos, ask=FALSE)

You should be careful to do this in an R session that does not hae any
packages attached, because attached packages cannot be updated.

The bioconductor release is being finalized, so you might find it
helpful to run update.packages again after the release.

Please let the list know if this solves your problem. 

Martin
