Hi,
You can take a look at John Storey's web site, he has R code there for
calculating
q-values, their version of the FDR. However, I don't think that they have
implemented the whole thing in R in anything publically avaialable, as
they are marketing their excel package.
You could always use the R-excel package at CRAN and just push the data
back and forth. Or do it the way most of us do:
write.table(...)
open excel,
do whatever
Save as csv
read.table(...)
etc.
