OrdinalRank Command

OrdinalRank[ <List> ]

Returns a list, whose i-th element is the rank of i-th element of list L (rank of element is its position in Sort[L]). If there are more equal elements in L which occupy positions from k to l in Sort[L], ranks from k to l are associated with these elements.

• OrdinalRank[{4, 1, 2, 3, 4, 2}] returns {5, 1, 2, 4, 6, 3}
• OrdinalRank[{3, 2, 2, 1}] returns {4, 2, 3, 1}
