[R] apply kendall tau to a split data set

[John Kane]

It helps to have a bit more detail and some sample data. Have a look at Reproducibility
http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example and http://adv-r.had.co.nz/Reproducibility.html
for some ideas of how to pose a question on the list.
