Dear R-Users,
I need a matrix containing line by line all possible permutations with
length 'i' of the integers 1:N, given the restriction that the
integers in each row have to be in ascending order.
For example: N = 5, length i = 3, should result in a matrix like this:
1 2 3
1 2 4
1 2 5
1 3 4
1 3 5
1 4 5
2 3 4
2 3 5
2 4 5
3 4 5
I'm grateful for any advice on how to proceed,
Michel Lang
