In tidyclust: A Common API to Clustering

cluster_metric_set works

Code
  my_metrics(kmeans_fit)
Condition
  Error in `value[[3L]]()`:
  ! In metric: `silhouette_avg`
  Must supply either a dataset or distance matrix to compute silhouettes.

cluster_metric_set error with wrong input

Code
  cluster_metric_set(mean)
Condition
  Error in `validate_function_class()`:
  ! 
  The combination of metric functions must be:
  - only clustering metrics
  The following metric function types are being mixed:
  - other (mean <namespace:base>)

Code
  cluster_metric_set(sse_ratio, mean)
Condition
  Error in `validate_function_class()`:
  ! 
  The combination of metric functions must be:
  - only clustering metrics
  The following metric function types are being mixed:
  - cluster (sse_ratio)
  - other (mean <namespace:base>)

cluster_metric_set errors with advice for some functions

Code
  cluster_metric_set(silhouette)
Condition
  Error in `cluster_metric_set()`:
  ! `silhouette` is not a cluster metric. Did you mean `silhouette_avg`?

Code
  cluster_metric_set(sse_within)
Condition
  Error in `cluster_metric_set()`:
  ! `sse_within_total` is not a cluster metric. Did you mean `sse_within_total`?
