model_fit method

Code
  last_fit(lm_fit)
Condition
  Error in `last_fit()`:
  ! `last_fit()` (`?tune::last_fit()`) is not well-defined for fitted model objects.
  i `last_fit()` (`?tune::last_fit()`) takes a model specification (`?parsnip::model_spec()`) or unfitted workflow (`?workflows::workflow()`) as its first argument.

workflow method

Code
  last_fit(lm_fit)
Condition
  Error in `last_fit()`:
  ! `last_fit()` is not well-defined for a fitted workflow.

ellipses with last_fit

Code
  linear_reg() %>% set_engine("lm") %>% last_fit(f, split, something = "wrong")
Condition
  Warning:
  The `...` are not used in this function but 1 object was passed: "something"
Output

argument order gives errors for recipe/formula

Code
  last_fit(rec, lin_mod, split)
Condition
  Error in `last_fit()`:
  ! The first argument to `last_fit()` should be either a model or workflow, not a <recipe> object.

Code
  last_fit(f, lin_mod, split)
Condition
  Error in `last_fit()`:
  ! The first argument to `last_fit()` should be either a model or workflow, not a <formula> object.

last_fit() when objects need tuning

2 arguments have been tagged for tuning in these components: model_spec and recipe.
i Please use one of the tuning functions (e.g. `tune_grid()`) to optimize them.
