[R] Dependency modeling - "chi-plot" and "kendall-plot"

[Zhao Nan]

Dear R users, 

I was trying to find a library for the Chi-plot and Kendall plot, 
as described in the paper "Everything you always wanted to know about 
Copula Modeling but you were afraid to ask", but unsuccessfully. I 
was wondering if anyone have already implemented these 2 functions in R
and could kindly help me out?  

Many thanks in advance, 

Nan
