[R] Variance Components

[Spencer Graves]

"lme" in library(nlme) is vastly superior in many ways to varcomp, but 
has the disadvantage of being difficult to use, at least in my 
experience.  When I need it, I also refer to José C. Pinheiro and 
Douglas M. Bates (2000) Mixed-effects models in S and S-PLUS (NY:  New 
York : Springer).  I highly recommend this book.

I hope this helps.
