# Calculating Statistical Power after Multiple comparison tests?

I'm currently using the multtest package in R, and I am curious to see how the statistical power holds up in a FWER vs. FDR based corrections.

Say for example:

pval <- c(0.018,0.034,0.726)


Is there anyway I can get the details of the power of the test retrospectively, using either this package or any other package? Or is what I am asking not making anysense?
