I have two sets of CEL files: one from MOE430A and one from MOE4302. I would like to normalize similar probe sets across the chip types but I am unable to combine Affybatches as they are different sizes. This was touched on previously in this list serve concerning the combination of HGU133A and HGU133 Plus2.0 chips. I could not, however, find an answer to the problem in this thread. I was thinking I could restructure the existing MOE4302 affybatch by subtracting/removing the MOE430B probe set data and then proceed to combining this with the existing MOE430A affybatch. I am able to perform routine R manipulations but the subtracting scheme detailed above is beyond my scope.

Can you be more be more specific about "unable to combine Affybatches as they are different sizes"? Did you try the function combineAffyBatcg from package matchprobes?
