[BioC] Combining objects of marrayRaw

[Tzulip Phang]

Hi All,

Is there any way to combine two or more marrayRaw class objects?  For 
example, if I use read.GenePix to read in two different cDNA datasets 
into two different marrayRaw objects, and later on I want to combine 
both together into one single object.

Any advice?

Thank you
