Hi,

I have some questions about p.adjust.

"The false discovery rate is a less stringent condition than the family wise
error rate, so these methods are more powerful than the others.", these
methods refer to FDR methods or FWER methods. Simply what are the
differences/pros/cons of both classes of methods.

The '"BH"' and '"BY"' methods control the false discovery rate, are they FDR
method ?

"fdr" stands for false discovery rate, how different is it from BH or BY ?

Lastly, which method should I use concerning microarray analysis for
selecting differentially expressed genes.

TIA
