How can we extract raw expression values in the oligo package?


I have Affymetrix, ST arrays and would like to obtain a matrix of raw expression values.


I tried the exprs function, however that gave me a million rows for the probes…I guess it wasn't summarized into probesets yet?.

raw.expr=exprs(raw) # this did not work

I appreciate the insight.

You will have to clarify what you want, as 'raw expression values' can mean any number of things.
