Subject: Re: [Rd] Something strange in cor.test in R-1.8.0 (PR#4718)
Without knowing the seed used it is impossible for us to reproduce this,
but I am not seeing anything strange.
Could you please reply with a reproducible example (and list the data used
too, in case the random number generation is the issue).
