[BioC] Plotting Gene Expression Values

[McGee, Monnie]

Dear BioC,

I have completed an analysis of a set of microarray data (affy data), and I would like to plot the gene expression values.  The purpose is to compare the genes in my four groups that are differentially expressed.   I've done histograms and boxplots, but what I really want is a gene-by-gene comparison.  How do I plot an expression set and how do I make sure that each of the expression values on the plot is labelled with the proper gene?

Thanks,
Monnie
