tune model only - failure in formula is caught elegantly

Code
  cars_res <- tune_cluster(helper_objects$kmeans_mod, ~z, resamples = data_folds,
  grid = cars_grid, control = tune::control_grid(extract = function(x) {
    1
  }, save_pred = TRUE))
Message

Condition
  Warning:
  All models failed. See the `.notes` column.

argument order gives errors for recipes

Code
  tune_cluster(helper_objects$rec_tune_1, helper_objects$kmeans_mod_no_tune,
  rsample::vfold_cv(mtcars, v = 2))
Condition
  Error in `tune_cluster()`:
  ! The first argument to [tune_cluster()] should be either a model or workflow.

argument order gives errors for formula

Code
  tune_cluster(mpg ~ ., helper_objects$kmeans_mod_no_tune, rsample::vfold_cv(
    mtcars, v = 2))
Condition
  Error in `tune_cluster()`:
  ! The first argument to [tune_cluster()] should be either a model or workflow.

ellipses with tune_cluster

Code
  tune_cluster(wflow, resamples = folds, grid = 3, something = "wrong")
Condition
  Warning:
  The `...` are not used in this function but one or more objects were passed: 'something'
Output
  # Tuning results
  # 2-fold cross-validation 
  # A tibble: 2 x 4
    splits          id    .metrics         .notes

select_best() and show_best() works

Code
  tmp <- tune::show_best(res)
Condition
  Warning:
  No value of `metric` was given; metric 'sse_within_total' will be used.
