mm(abatch, probeid)

Hello,
sorry if this is a RFTM, but after reading the Affy vignette a few
times, I
can't find the answer, and I know it must be easy!
I've loaded the Affy library and read my chips into bioconductor. I've
no
problem accessing PM and MM data by Index as shown in the vignette
(4.1
Accessing PM and MM Data), however I can't see how to access the same
data
by AffyID.
Any help would be appreciated,
Donald
