How can
I compute a measure of fit of Generalized Linear Mixed Models 
(more specifically
a lmer-object). Does a package similar to ?Lmmfit? 
exists for glmm objects?  

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.
