Quantiles for discrete distributions are consitently implemented, but inconsitently documented. Help for qpois incorrectly states in the Details section that
"The quantile is left continuous: qgeom(q, prob) is the largest integer x such
that P(X <= x) < q."
which disagrees with the implementation; it should read
"The quantile is defined as the smallest value x such that F(x) >= p, where F
is the distribution function."
Also, this definition should be added to Help for qhyper.
