In tidymodels/recipes: Preprocessing and Feature Engineering Steps for Modeling

check_name() is used

Code
  prep(rec, training = dat)
Condition
  Error in `step_interact()`:
  Caused by error in `bake()`:
  ! Name collision occurred. The following variable names already exist:
  * `x1ax2`

gives informative error if terms isn't a formula (#1299)

Code
  recipe(mpg ~ ., data = mtcars) %>% step_interact(terms = starts_with("dis")) %>%
    prep()
Condition
  Error in `step_interact()`:
  Caused by error:
  ! `terms` must be supplied as a formula.

Code
  tmp <- recipe(mpg ~ ., data = mtcars) %>% step_interact(~ disp:am) %>% prep(
    strings_as_factors = FALSE)
Condition
  Warning:
  Categorical variables used in `step_interact()` should probably be avoided; This can lead to differences in dummy variable values that are produced by ?step_dummy (`?recipes::step_dummy()`). Please convert all involved variables to dummy variables first.

bake method errors when needed non-standard role columns are missing

Code
  bake(int_rec_trained, dat_tr[, 4:6])
Condition
  Error in `step_interact()`:
  ! The following required columns are missing from `new_data`: z and x1.
