I have been using the affy package to summarize and filter .cel files
into
expression sets, then exporting these sets into SAM (Significance
Analysis
of Microarrays) to select differentially expressed genes.
This is getting cumbersome; it would be more straightforward to do
everything in R.
Does anyone have functions for SAM in R, or can I use any of the
existing
bioconductor packages to select differentially expressed genes in a
way
similar to SAM?
Thanks
