I have a list that I need to be able to assign ranks to individual elements in, giving it a number related to its position if the list were to be sorted, allowing for ties. For example, { 6, 3, 3, 6, 4, 4, 6, 4} would be transformed to { 1, 3, 3, 1, 2, 2, 1, 2} or { 3, 1, 1, 3, 2, 2, 3, 2} depending on if I were sorting for higher values or lower values.
This is for a variant on PageRank, in which after assigning each point or edge a value, the set of all edges or points is ranked, with the highest ranked point(s) getting the number 1, the second highest point(s) getting 2, and so on. I have tried using Sort and other approaches, but have not encountered anything that could be described as elegant.
