Dear R team,
I have a simple question.
I tried this command:
phyper(17,449,19551,181, FALSE)
[1] 1.47295e-07
and then I tried this command:
(fisher.test(matrix(c(17,449,181,19551),2,2),
alternative='greater'))$p.value
[1] 3.693347e-06
Shouldn't be identical the results of the two commands ?

I ask the question also because I found this line in Wikipedia:
The test (see above) based on the hypergeometric distribution
(hypergeometric test) is identical to the corresponding one-tailed
version of Fisher's exact test.
Is this wrong ? May I kindly ask a friendly explanation for

Such harsh words Peter. You're not making this a friendly environment for
people to ask questions. Is there a less competent attribute mailing list so
that some of us don't offend you with our questions?
