[BioC] deleting probes in expression set

[Vanessa Vermeirssen]

Hi,

I have created eSets from RGLists for cDNA microarrays. I would like to 
combine in the end data from several
different platforms. As a special case, I would like to combine 2 eSets 
with the same gene probes, but in a different order on the array (so 2 
different array platforms).
The IDs of my probes are not unique, so I cannot use them as 
FeatureNames...some have a duplicate in there (extension #2 after its 
name) and the control probes are
not uniquely named e.g. luciferase (10 x).
Is there a way to delete the duplicates or integrate their information 
in the original (taking the average)? How to delete the control probes? 
This would enable me to end
up with unique IDs, so I could use them as feature names and then it is 
fairly easy to combine the two expression sets.

In another stage, when combining from different platforms with different 
genes, I would like to extract just the information for a specific gene 
probe list. Is this possible?

I am new to Bioconductor, but learning a lot every day... I hope that 
somebody can help me.

Thanks so much already,
Vanessa Vermeirssen
