[BioC] bout big data set for Affy R packge

[James W. MacDonald]

Hi Wei Liu,

You can try justRMA(). If that doesn't work, you can try the 
aroma.affymetrix package. Note that the aroma.affymetrix package is not 
part of BioC, and has its own user group and repository, so you need to 
do a google search for that one.

Best,

Jim
