Does anybody know a R package or function to compare expression level 
(affy data) of two groups with no replicates in each group ? In fact, 
just compare one array to an other.
The purpose is to find differentially expressed genes.
We cannot used statistical test (not enougth replicates), but we can 
used graphical approach based on scatter plot, and outliers detection 

Thanks for your help,
