[R] Kendall's tau-c

[Knut Wenzig]

Hello,

I can't find a package which calculates Kendall's tau-c. There is the
package Kendall, but it only calcuates Kendall's tau-b.

Here is the example from
ttp://www2.chass.ncsu.edu/garson/pa765/assocordinal.htm.

cityriots <- data.frame(citysize=c(1,1,2,2,3,3),
riotsize=c(1,2,1,2,1,2), weight=c(4,2,2,3,0,4))
cityriots <- data.frame(lapply(cityriots,function(x)
rep(x,cityriots$weight)))
xtabs(~ riotsize+citysize,cityriots)

tau-c should be .57.

Do you have a hint?

Best regards

Knut Wenzig
