[BioC] Error in intgroup of arrayQualityMetrics package

[Wolfgang Huber]

Dear Sonal

thank you for reporting this. Sorry that you have trouble. But we will 
need more information about your problem to help you.

What do you get as output from the following lines of R code:

sessionInfo()
intgroup
str(intgroup)
pData(eset)
colnames(pData(eset))

	Best wishes
	Wolfgang
