I am attempting to create a function to calculate the binomial formula, but I keep getting the error "Range out of value in gamma fn"

mything <- function(x, n, p) {
  a = choose(n, x)
  b = p^x
  c = (1 - p)^(n - x)
  d = a * b * c
  return(d)
}

mything(20, 2000, 0.01)

Your example doesn't give any error. – Feb 13 '15 at 04:55
That code throws no error. – IRTFM Feb 13 '15 at 07:41
There is a standard R function for this: `dbinom(20,2000,0.01)` – Stibu Feb 13 '15 at 08:05
