It's not at all clear what you are attempting to do, but there are a few
strange things in your code:

ee is already an environment; why use as.environment?

Ditto.

What have those got to do with the problem of interest?  It's a good
idea to post "minimal" examples; distractions are distracting.

What is groupedData?  We also ask for self-contained examples, and that
isn't in the default packages.  Are you talking about the function in
nlme?  If so, do you expect it to make use of ee?  It never sees ee.

And where does y come from?
