[BioC] normalize AffyBatch object by control spots?

[Jenny Drnevich]

Hi all,

Does anyone know of an existing function in any package to normalize an 
AffyBatch object using a set of control probesets only? I've looked through 
the functions in the affy package and searched the archives, but couldn't 
find anything. There is an option similar to what I want in the 
normalizeWithinArrays(method="control") function in limma, but I wanted to 
find out if I had missed something before trying to write my own function.

Thanks,
Jenny
