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

I think you can use setequal(a,b)

Updated update setequal checks if two vectors are composed of the same elements but it does not check if these elements have the same occurrences in each vector.
