R help - Jul 2000 - factorial(), modulus()

Dear R friends,

I was wondering if there were factorial and modulus functions out there
that I've somehow overlooked?

There's  gamma and lgamma for factorials

gamma(x+1) is x! and lgamma(x+1) is log(x!).  Also choose() and
lchoose() for the binomial coefficients.

x %% y does x mod y.
