[R] Kendall package tau-a, b, and c

[Rui Barradas]

Hello,

I've followed your link (thanks) and in the presence of ties the value 
of R's cor.test, method = "kendall", in package stats and kendall_tau_b 
in the link are the same. If you have ties, cor.test will issue a 
warning but that is relative to the p-value only, the reported tau, 
under "sample estimates" is tau-b.

See ?cor.test

Hope this helps,

Rui Barradas
