  It might exist (but not that I know of); you might use the sos
package to look for it.  The problem is that the difficulties of
computing goodness-of-fit for LMMs (see references in the lmmfit
package) are compounded by the difficulties of computing
goodness-of-fit for GLMs (see e.g.
http://finzi.psych.upenn.edu/R/library/descr/html/LogRegR2.html ) ...
