How to sample permutation in r without repeating permutations in R

#1
Hi guys.

I was wondering is it possible to create a matrix or a vector of permutations without repeating them.

E.g. create a matrix of 4! = 24 permutations.

The way I started is:

k <- 4
n <- factorial(k)

x <- matrix(NA,nrow= n, ncol =k)
for (i in 1:n){
x[i,] <- sample(k)
}

But i'm repeating some of the permutations.
Help is appreciated.
