works with logicals

Code
  recipe(~., data = mtcars) %>% step_bin2factor(all_logical_predictors(),
  ref_first = 1)
Condition
  Error in `step_bin2factor()`:
  ! `ref_first` must be `TRUE` or `FALSE`, not the number 1.

bad options

Code
  prep(rec3, training = covers)
Condition
  Error in `step_bin2factor()`:
  Caused by error in `prep()`:
  x All columns selected for the step should be double, integer, or logical.
  * 1 factor variable found: `description`

Code
  rec %>% step_bin2factor(rocks, levels = letters[1:5])
Condition
  Error in `step_bin2factor()`:
  x `levels` should be a 2-element character string.
  i 5 elements were supplied; two were expected.

Code
  rec %>% step_bin2factor(rocks, levels = 1:2)
Condition
  Error in `step_bin2factor()`:
  x `levels` should be a 2-element character string.
  i It was an integer vector.

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

Code
  bake(rec, mtcars)
Condition
  Error in `step_bin2factor()`:
  ! The following required column is missing from `new_data`: bin.
