[BioC] Selected probes from a given probeset

[Ramiro Rodríguez]

Dear list,
I´m using Bioconductor for Affymetrix AtH1 microarray analysis.
I was wondering if there is a way to get expression values for a given
gene (probeset), but using only a subset of the probes from the probeset.
Thanks to all in advance,
Ramiro.
