R help - Feb 2012 - Any package for best subset selection on random effects model?

Hi Pros,
     I know leaps() computes the best subset selection for linear model, and
the bestglm() computes the best subset selection for generalized linear
model. Is there any package for best subset selection on random effects
model, or mixed effects model?

Thank you so much.

  glmmLasso on CRAN ; possibly try the MuMIn package (specifically
the dredge command).  You might have better luck with this question
on the r-sig-mixed-models at r-project.org list.
