Reciprocal Mill's Ratio
I believe that this may be more appropriate here in r-devel than in r-help.

small values of z. The latter formula breaks dowm numerically for me
(running R 2.4.1 under Windows XP 5.1 SP 2) for values of z near 37.4
or greater.
Looking at the pnorm documentation I see that it is based on Cody (1993)
and thence, going one step further back, on Cody (1969). Consulting
