How to merge AffyBatch object from different Affymetrix platforms

Question

[zaynabmousavian]

Hi,

I have two AffyBatch objects, each one constructed by reading cell files of the microarray data of different platforms including HGU133A and HGU133Plus2:

object1=ReadAffy(verbose=TRUE, filenames=cels1, cdfname="HGU133A_HS_ENTREZG")
object2=ReadAffy(verbose=TRUE, filenames=cels2, cdfname="HGU133PLUS2_HS_ENTREZG")

I need to combine these objects before doing normalization. How can I do this in R?

I mostly appreciate any help.

Thanks
