This function estimate the qvalue
based on p-values and an estimate of the
proportion of true null hypotheses, pi0.

p |
a numeric vector of p-values |
pi0 |
numeric, a given estimate of the proportion of true null hypotheses, pi0, truncated to [0,1].

The estimation of q-value/FDR is the simple and quick plug-in method:
q_i = min_{i<=j<=G} G*pi0*p_(j)/j
.
a numeric vector of the same length as p
, giving the estimated q-values corresponding to each p-value.
This implementation avoids explicit loops and is much faster when the number of p-values are very large.
