R help - Apr 2012 - calculate correlation effect size using contrast analysis for an omnibus Chi-square test statistic

I am looking for an R package with which one can calculate an effect size for a
set of contrasts given an omnibus chi-square test statistic (more than 1 degree
of freedom). Is there such a package? Presumably, it would implement the
procedure (or something like it) described by Roznow and Rosenthal 1996
Psychological Methods 1: 331-340.

many thanks!

Does the compute.es package do what you want? I have never used it 
but it does have a function chies which appears promising.
