bad args

Code
  prep(step_tfidf(recipe(~., data = mtcars), vocabulary = 1:10))
Condition
  Error in `step_tfidf()`:
  Caused by error in `prep()`:
  ! `vocabulary` must be a character vector or `NULL`, not an integer vector.

Code
  prep(step_tfidf(recipe(~., data = mtcars), smooth_idf = "yes"))
Condition
  Error in `step_tfidf()`:
  Caused by error in `prep()`:
  ! `smooth_idf` must be `TRUE` or `FALSE`, not the string "yes".

Code
  prep(step_tfidf(recipe(~., data = mtcars), norm = "yes"))
Condition
  Error in `step_tfidf()`:
  Caused by error in `prep()`:
  ! `norm` must be one of "l1", "l2", or "none", not "yes".

Code
  prep(step_tfidf(recipe(~., data = mtcars), sublinear_tf = "yes"))
Condition
  Error in `step_tfidf()`:
  Caused by error in `prep()`:
  ! `sublinear_tf` must be `TRUE` or `FALSE`, not the string "yes".

Code
  prep(step_tfidf(recipe(~., data = mtcars), prefix = NULL))
Condition
  Error in `step_tfidf()`:
  Caused by error in `prep()`:
  ! `prefix` must be a single string, not `NULL`.

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

Code
  bake(trained, new_data = tokenized_test_data[, -1])
Condition
  Error in `step_tfidf()`:
  ! The following required column is missing from `new_data`: text.

empty printing

keep_original_cols - can prep recipes with it missing

Code
  rec <- prep(rec)
Condition
  Warning:
  `keep_original_cols` was added to `step_tfidf()` after this recipe was created.
  i Regenerate your recipe to avoid this warning.
