[R] Effect size measures for GLM

[Gianfranco Lovison]

Is there a library for (friendly) calculation of effect size measures for
Generalized Linear Models? I have found "compute.es", but it seems to be
suitable only for Linear Models. A library taking a glm object and computing
partial R^2-type statistics, appropriate for GLMs, would be enough, but I have
bee unable to find it!

Rhanks for your help.
