Dear R-Help,

I am using R2.3.0, nlme library on Windows XP.

I created a grouped data object with y, subject, group and time variables.

I can plot the data using

plot.nfnGroupedData(form=y~time|subject,outer=~group)

This gives me individual curves (connected points) for each subject in separate panels for each group.

I would also like to add to the plot a curve with the mean y at each time point for each group. how can I do that?

Thanks
