Hello,
  in affy package, we can get probe level raw data using pm or mm methods as below:
   
  > library("affydata")
  > data(Dilution)
  > pm(Dilution, "1001_at")[1:3, ]
   
                 20A  20B  10A 10B
  1001_at1 129 93 130 73.8
  ...
   
  if I use aroma.affymetrix as below:
  > cs <- AffymetrixCelSet$fromName("anth", chipType="HuEx-1_0-st-v2")
> cdf <- AffymetrixCdfFile$fromChipType("HuEx-1_0-st-v2");
> setCdf(ds, cdf);
   
  how can I get pm or mm data from cs. something like >pm(cs, "1001_at")[1:3,]?
   
   
  thanks
  yuan
