Computes q values from a vector of local fdr estimates
qval.from.lfdr(lfdr)
vector of q values
a vector of local fdr estimates
The q value for a given lfdr is an estimate of the (tail) False Discovery Rate for all findings with a smaller lfdr, and is found by the average of the lfdr for all more significant findings. See Storey (2003), Annals of Statistics, for definition of q value.
