[BioC] AffylmGUI

[Gordon Smyth]

Dear K Chen,

The new option "BH" is the same as the old option "fdr". The new 
names were introduced into the p.adjust() function in R 2.2.0 because 
there are now two FDR control methods (BH and BY). See ?p.adjust

We removed the Bonferroni, Hochberg and Hommel options because we 
don't think these are ever the best options for microaray data.

Best wishes
Gordon
