errors when there are too few distinct observations

Code
  cluster_centroids(df, "class")
Condition
  Error in `cluster_centroids()`:
  ! Not enough distinct observations in "majority" to compute 3 clusters.
  i 1 distinct observation was found.
  i Try a smaller `under_ratio` or remove duplicated rows.

bad args

Code
  cluster_centroids(circle_numeric, "x")
Condition
  Error in `cluster_centroids()`:
  ! `x` should refer to a factor or character column, not a double vector.

Code
  cluster_centroids(circle_example, "class")
Condition
  Error in `cluster_centroids()`:
  ! All columns for this function should be numeric. Non-numeric column found: `id`.

Code
  cluster_centroids(circle_numeric, "class", under_ratio = "yes")
Condition
  Error in `cluster_centroids()`:
  ! `under_ratio` must be a number, not the string "yes".

Code
  cluster_centroids(circle_numeric, "class", voting = "medium")
Condition
  Error in `cluster_centroids()`:
  ! `voting` must be one of "soft" or "hard", not "medium".
