[BioC] Affy vs. cDNA : Low and not expressed genes

[Adaikalavan Ramasamy]

Thank you Stephen Henderson, Richard Park and Laurent Gautier for their
extremely helpful suggestions.

The biologist like the idea of FC-FC plot but I decided to present then
t-values plot in order to account for the variations (after some
convincing that t-values do account for FC wrt to variation, sigh).

Given the fact that there were only 3 replicates, I think I have
salvaged as much as could be. Thank you again !
