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.
