The first parameter X is the data set (Array).

The second parameter R is the ranks data (list or Array).

The options argument can contain one or more of the options shown below.

order = ascending or descending -- Indicate whether the elements of X should be sorted in the ascending or descending order. The default value is order=ascending.

unique=truefalse -- If this option is set to true, all multiple occurrences of elements from X will be removed. The default value is unique=false.

The OrderByRank command creates a copy of the original Array.
