randomly combine numeric vectors in r

Question

I'm using R. Let's say I have four numeric x1,x2,x3,x4 and each of them have length about 50 to 100. Then, I want to combine them and I use c(x1,x2,x3,x4). Is there any way that I can randonmly combine them. For example, c(x1,x3,x4,x2),c(x3,x1,x2,x4).

Answer 1

Put them in a list , shuffle the order of the list , and then unlist() them into a single vector.

result = list(x1, x2, x3, x4)
result = result[sample(seq_along(result))]
result = unlist(result)
