[R-sig-ME] mixed effect modeling with imputed data set

[ali]

Hi all
I imputed my data using multiple imputation procedure in STATA. I would like
to conduct mixed effect modeling on the imputed data set in R. I do not know
how to write the code over the imputed data set.
My code is:	
fit <- glmer(y ~ x1+x2 +x3+(1|regiogid),family= binomial("logit"), data =mydata)

Best Regards
