Hi Jerry,
I am going to assume you saw and read the warning, considering you
printed it out.
It says that you should be using the oligo or xps packages. So that is
step #1. Use one of those two packages instead of the affy package.
There are vignettes for both packages that you can read to help you get
started. Note that you can summarize the Gene ST arrays at either the
transcript or probeset (roughly exon) level, so the annotation package
you will need to map probesets to genes, etc, will either be the
hugene11sttranscriptcluster.db or hugene11probeset.db package.
Best,
Jim
