Hi:

  Let me withdraw my previous email.
---------------------------

 I guess you mis-specified the function.  Use
    cor(x, y, method="kendall")

Hi, guys,
     I have 2 different ranking lists of 1000 vertices of a graph.
  Like, L1={1 ,3 ,4, 5 .......}
          L2={ 2, 5, 6, 100....}..
    The numbers in each ordering list are the labels of the vertices. For example, 4 means the 4th vertex in the graph.

     Now I need to calculate the kendall's tau correlation foeffienct of these two ranking lists.

I uses cov(x, y, method="kendall") . But it did not work.
Anybody can give  me any idea?
Thanks a ton.
