• choose(n,k) = choose(n-1, k)+choose(n-1,k-1). I implemented in R and Fortran 90 the same algorithm (code follows). apart from octave (which seems to have a _real_ issue with recursive function calls), R is by far the slowest in this list and still a factor 7-20 slower than the interpreter based Lua and ruby...

2. ## N Choose K function in R not working--what am I missing? - Stack Overflow

You can tell this from the example you posted by looking at the top of the page: You'll notice the "R.basic" in the curley braces which tells you that that function is a part of the "R.basic" package. So to use nChooseK you'll first need to load that package.

3. ## R: Special Functions of Mathematics

• The functions choose and lchoose return binomial coefficients and the logarithms of their absolute values. Note that choose(n, k) is defined for all real numbers n and integer k. For k ≥ 1 it is defined as n(n-1)…(n-k+1) / k!, as 1 for k = 0 and as 0 for negative k...
