[R] Function for Generating all Permutations with Repetition

[Martin Spindler]

Dear all,

I am looking for a function in R which returns all possible permutations of an object x with r number of repitions. For example

If x <- c(0,1) and r <-3 the result should be

0 0 0
0 0 1
0 1 0
0 1 1
1 0 0
1 0 1 
1 1 0
1 1 1

and consist of 2^3=8 elements.
Unfortunately, I have found only functions which return the combinations for "choose n over k" but not the case described above.
I would appreciate hints and help highly.

Best,

Martin
