R^2 for Generalized Mixed Models

Note for myself. Check this: Nakagawa, S. & Schielzeth, H., 2013, A general and simple method for obtaining R2 from generalized linear mixed-effects models.  Methods in Ecology and Evolution, 4: 2, pp 133–142, DOI: 10.1111/j.2041-210x.2012.00261.x EDIT 20131027: R implementation is available: http://jslefche.wordpress.com/2013/03/13/r2-for-linear-mixed-effects-models/  Also MuMIn package contains implementation (http://cran.r-project.org/web/packages/MuMIn/index.html)
