[R] Special Functions calculations

Hello r-help,

I notice that r includes distribution, and quantile values for the
Chi-Square, F, t, and normal functions.  Could someone give me some good
reference(s) for how these probabilities and quantiles are calculated.
I have already calculated the normal probability values using  a Taylor
expansion (http://www.sisweb.com/math/tables.htm).

I realize these calculations must be very difficult, but I think it is
insulting to our intelligence by mathematicians to hide the solutions to
the CDFs from us like this.
