by "grouped data" are you saying that you have counts of outcomes and counts
of trials?
That is how I interpret the glogit in stata.  If that is the case you can
put your data into glm()
like this

fit<-glm(nevents~xvars, weights=ntrials, family=binomial, data=yourdataset)
will fit the binomial regression model

will print the coefficients and model fit

In the future could you please read the posting guide and put in a data
example or some R code you have tried.
