[BioC] GEO: Finding up- and down-regulated genes in GDS records

[Sean Davis]

There is not a way to get this information from R or from the website,
for that matter.  That said, you can download the data and perform
local calculations using R.  See the GEOquery package for the
"download" part and the limma package, for example, for the analysis
side of things.
