bad data

Code
  rec %>% step_impute_lower(carbon, hydrogen, has_neg) %>% prep()
Condition
  Error in `step_impute_lower()`:
  Caused by error in `prep()`:
  x The following columns negative values: has_neg.
  i Lower bound imputation is intended for data bounded at zero.

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

Code
  bake(imputed_trained, new_data = biomass[, 4:7])
Condition
  Error in `step_impute_lower()`:
  ! The following required column is missing from `new_data`: carbon.
