"Undefined columns selected" in compare.fits when trying to show models with poly()

[amazingoats]

Hi Dustin,
I have models that contain the poly() function, and they won't work in compare.fits unless I've added another model first that doesn't contain the poly() function. I would like to just be able to model them on their own or compare them to other models with the poly() function, but it gives me an error.

For example:
m1 = lm(Var1 ~ Var2 + Var3 + poly(Var3, degree=3) ,data=d)
m2 = lm(Var1 ~ Var2 + Var3 + I(Var3^3), data=d)

If I enter: compare.fits(Var1Var3 | Var2, data=d, m2) - It works
If I enter: compare.fits(Var1Var3 | Var2, data=d, m2, m1) - It works

If I enter: compare.fits(Var1Var3 | Var2, data=d, m1) or compare.fits(Var1Var3 | Var2, data=d, m1, m2)

I get this error:
Error in purrr::map():
ℹ In index: 1.
Caused by error in [.data.frame:
! undefined columns selected
Backtrace:

1. flexplot::compare.fits(...)
2. purrr::map(., return_constant_for_predicted_data, data = k, model = model)
3. purrr:::map_("list", .x, .f, ..., .progress = .progress)
4. flexplot (local) .f(.x[[i]], ...)
5. base::[.data.frame(data, , missing_variable)
6. base::stop("undefined columns selected")

Any help would be appreciated! Thank you.
