Subject: [Rd] negative p-value from fisher.test() (PR#7064)
Message-ID: <20040707151901.107BA108C7@slim.kubism.ku.dk>

I obtained a negative p-value from the fisher.test() function:

> fisher.test(matrix(c(14576,3023,89,68),2), alternative="g")$p.value
[1] -8.426593e-13

With R 1.8.1, I got a p-value of -6.239231e-12 for this example.
