You probably need to repost this on r-help instead of r-devel; it's not a "development" question. The other bad news for you is that I suspect it may be difficult to define r-squared uniquely for a mixed model. The resid() command will give you residuals, and you could take (1-resid()^2)/var(x) -- but how do you decide which var(x) to put in the denominator ... ?
