[BioC] get probe level intensity from Affymetrix Exon Array platform

[shirley zhang]

Dear Bioconductor,

 I usually obtain exon-level/gene-level signal using Plier/RMA
implemented in Affymetrix's Expression Console, however there is no
way to get probe level intensity from it. Does anybody know how to get
probe level intensity from Affymetrix Exon Array platform?

Thanks,
Shirley
