Yes. I could stop there but you shouldn't. The author of the package
provides plenty of examples (and two good vignettes) showing you how to do
this. Suggest you do some work in that area. Look especially at how model
formulas are used/specified. This is at least one area where you have gone
wrong, as the error message clearly tells you.

Good luck.
Mark.
