Hello All,

I perform a Wilcoxon signed rank test for two sets of data to test whether
they two have significantly different means. I would also like to know the
power of this test.

The third part of this tutorial is similar to what I want except the t
distribution.  http://www.cyclismo.org/tutorial/R/power.html#multiT 

Could anyone help? Or let me know if my question is a nonsense one. Thanks
in advance.
