[BioC] Boxplot from dataframe...

[David Ruau]

I found out finally how to have the names of the experiments printed on 
the x axis by using the phenoData define in the affyBatch.
###
boxplot(exprs(abatch)[rownames(exprs(abatch))==id] ~ abatch$population, 
col=colors, axes=FALSE)
title(main=y, sub=id)
axis(1, at = 1:length(unique(da.gcrma$population)), labels = 
as.list(unique(da.gcrma$exp)))
axis(2)
box()
