No, there is no way to get individual p-values corresponding to the
nestedF method. You can
however just used the overall F-test p-values, fit$F.p.value, which
will give you p-values at the
probe level rather than the contrast level. Use
p.adjust(fit$F.p.value)
to get adjusted p-values. The nestedF method will give at least one
significant contrast for a
given probe if and only if the above adjusted p-value is less than the
cutoff.
