Check whether two vectors contain the same (unordered) elements in R

Question

I\'d like to check whether two vectors contain the same elements, even if they\'re not ordered the same. For example, the function (let\'s call it SameElements)

Answer 1

In lieu of a cleaner alternative, here's the known solution:

SameElements <- function(a, b) return(identical(sort(a), sort(b)))
SameElements(c(1, 2, 3), c(1, 3, 2))  # TRUE
SameElements(c(1, 2, 3), c(1, 1, 3, 2))  # FALSE

Edit: identical instead of all.equal(...) == T per nrussell's suggestion.
