`n`	Numeric. Number of elements to choose from.
`r`	Numeric. Size of the desired subsets.
`v`	Vector. Numeric or character vector of size `n` with the labels of the n elements to choose from.

A matrix of dimension (N x r), where N is the total number of different combinations of r elements chosen from n possible.

This particular version of the function was taken from a message from Bill Venables to ‘r-help’ list on Sun, 17 Dec 2000.
