--- Comment #1 from Wayne Rasband <wsr at nih.gov> ---
This is the expected behavior. The rankPositions() function returns the rank
positions as indexes, starting with index of smallest value. Get the rank
positions of the indexes to get the ranks. Here is an example:

  test = newArray(15, 10, 50, 20, 40, 1, 2, 3);
  rank_pos = Array.rankPositions(test);
  rank = Array.rankPositions(rank_pos);
  Array.show(test, rank_pos, rank);

And here is the output:


 test  rank_pos  rank
 155     5        4
 10      6        3
 50      7        7
 20      1        5
 40      0        6
 1       3        0
 2       4        1
 3       2        2
