check_name() is used

Code
  prep(rec, training = dat)
Condition
  Error in `step_spline_natural()`:
  Caused by error in `bake()`:
  ! Name collision occurred. The following variable names already exist:
  * `mpg_01`

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

Code
  bake(rec_trained, new_data = mtcars[, -3])
Condition
  Error in `step_spline_natural()`:
  ! The following required column is missing from `new_data`: disp.

bad args

Code
  recipe(mpg ~ ., data = mtcars) %>% step_spline_natural(disp, deg_free = "a") %>%
    prep()
Condition
  Error in `step_spline_natural()`:
  Caused by error in `prep()`:
  ! `deg_free` must be a whole number, not the string "a".

Code
  recipe(mpg ~ ., data = mtcars) %>% step_spline_natural(disp, complete_set = 1) %>%
    prep()
Condition
  Error in `step_spline_natural()`:
  Caused by error in `prep()`:
  ! `complete_set` must be `TRUE` or `FALSE`, not the number 1.
