I am looking for an R package with which one can calculate an effect

Presumably, it would implement the procedure (or something like it)
described by Roznow and Rosenthal 1996 Psychological Methods 1: 331-340.
Does the compute.es package do what you want? I have never used it
but it does have a function chies which appears promising.
many thanks!
