It took me by surprise to find that choose(4,5) delivers
[1] NaN
Warning message:
NaNs produced in: choose(n, k)
If we look at choose(4,5) as the number of ways of choosing
5 objects from 4 I would have expected 0 as result.
Furthermore dhyper(5,4,6,5) does deliver 0 and this essentially
equivalent to choose(4,5)*choose(6,0)/choose(10,5).
I use R for Windows, Version 1.0.1 (April 14, 2000)
