[BioC] Getting dChip SNP intensity in BioC?

[Jeff Gentry]

Hi there ...

I'm probably just overlooking something obvious, but I didn't see this in
the oligo package.  I was hoping to be able to generate the signal
values for samples in SNP datasets in the same manner as dChip &
genepattern do.  As an example, the Genepattern .SNP file format each
sample has both an intensity and a call column.  

Thanks
