[BioC] Compare subsets using only probesets mapped to chromosome 10

[Martin McCabe]

Hi.  I've used Affy 133 Plus 2 Arrays on a series of samples and  
normalised the data using rma.  Can anyone tell me how to run eBayes  
to compare two subsets of samples (with and without monosomy of  
chromosome 10) using only probesets mapped to chromosome 10?

Thanks.
