[Numpy-discussion] numpy function to compute sample ranks

Hi, Is there a direct or indirect way in numpy to compute the sample ranks of a given array, i.e. the equivalent of rank() in R. I am looking for: rank(array([6,8,4,1,9])) -> array([2,3,1,0,4]) Is there some clever use of argsort() that I am missing? Thanks, Abhi
