bad args

Code
  rec %>% step_num2factor(w, x, levels = c("one", "two")) %>% prep(ex_dat)
Condition
  Error in `step_num2factor()`:
  Caused by error in `prep()`:
  x All columns selected for the step should be double or integer.
  * 1 factor variable found: `w`

Code
  rec %>% step_num2factor(w, x) %>% prep(ex_dat)
Condition
  Error in `step_num2factor()`:
  ! Please provide a character vector of appropriate length for `levels`.

Code
  rec %>% step_num2factor(z, levels = rev(LETTERS[1:10]), transform = 2) %>% prep()
Condition
  Error in `step_num2factor()`:
  Caused by error in `prep()`:
  ! `transform` must be a function, not the number 2.

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

Code
  bake(ex_1, new_data = ex_dat[, 1:2])
Condition
  Error in `step_num2factor()`:
  ! The following required column is missing from `new_data`: z.
