        These functions provide information about the binomial
        distribution with parameters `n' and `p'.  `dbinom'
        gives the density, `pbinom' gives the distribution
        function `qbinom' gives the quantile function and
        `rbinom' generates random deviates.

        The binomial distribution has density

                  p(x) = Choose(n,x) p^x (1-p)^(n-x)

        for x = 0, ..., n.
