[BioC] How to search for coexpression?

[stueber@mpiz-koeln.mpg.de]

Dear colleaques,

After reading data from affymetrix CEL files I would like to
get information about coexpressed and non-coexpressed genes for
a chosed set of probesets.

I start with:

>library(affy)
>Data <- ReadAffy()
>eset <- rma(Data)

This give me a big array of all intensities for
all probesets and experiments.
But what to do then?

Any hints appreciated.
