Hi,
 
I need to combine a set of HGU133a2 (68) and HGU133plus2 (57) chips. Found
the package matchprobes to be usefull for this purpose.... but since I have
to load my data by the read.affybatch function it takes up to much memory
just to do this part. 
 
Any smart short cut to avoid this memory problem?    
 
best regards
Anne
