I guess (because you are not telling us) that you would like to have an
estfun() method for "lmer" objects. I don't provide one in my sandwich
package (where the estfun generic is taken from) and AFAIK there is
nothing analagous readily available in "lme4"... But I guess that you
should be able to extract/compute the empirical estimating functions from
the fitted "lmer" object.

When you compute
it returns a "logLik" object that has a "df" attribute:
