Two things:
I think you are not aware of the R difference between a formula and a lm
object. A formula is part of the input to the lm function while the output
is a complicated object of lm class. If you want the formulas back from the
model object, you can access them by way of
model1$call with a little bit of string processing.
The other: nothing ever changes values of zzz (exactly the point of assign)
so it shouldn't surprise you it didn't change. What you may be looking for
is get(zzz)
