PLS-DA, dense loadings, multiple outcomes

Code
  prep(rec)
Condition
  Error in `step_pls()`:
  Caused by error in `prep()`:
  ! Only multivariate models for numeric outcomes are supports.

PLS-DA, sparse loadings, multiple outcomes

Code
  prep(rec)
Condition
  Error in `step_pls()`:
  Caused by error in `prep()`:
  ! Only multivariate models for numeric outcomes are supports.

check_name() is used

Code
  prep(rec, training = dat)
Condition
  Error in `step_pls()`:
  Caused by error in `bake()`:
  ! Name collision occurred. The following variable names already exist:
  * `PLS1`

Deprecation warning

Code
  recipe(~., data = mtcars) %>% step_pls(outcome = "mpg", preserve = TRUE)
Condition
  Error:
  ! The `preserve` argument of `step_pls()` was deprecated in recipes 0.1.16 and is now defunct.
  i Please use the `keep_original_cols` argument instead.

keep_original_cols - can prep recipes with it missing

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