[BioC] Could I use "genefilter" package for MArray data ?

[Wolfgang Huber]

Dear Xiaokuan

you don't use a package on an object - rather, you apply a function to 
an object (or multiple objects). The genefilter package contains many 
different functions. Which function is it exactly that you want to apply 
to your object?

	Best wishes
