[BioC] questions about Affy package from new user: one more question

[Lizhe Xu]

Now, I tried to load the exported data from Bioconductor to GeneSpring and found another question. Since I used U133 chip set, I wonder if I can joint the U133A and B directly and import them to GS or I should do probeset level normalization first (if so, which package in bioconductor can do it) before joint them. Thanks.
