clust_membership: Get cluster membership for each observation of an umapscan...
In juba/umapscan: UMAP and DBSCAN Pragmatic and Supervised clustering

Description Usage Arguments See Also Examples

The clusters taken into account are all the "leaves" of the object clusters tree. If a parent is specified, only the leaves of its subtree are taken.

clust_membership(
  us,
  parent = "",
  max_level,
  noise_inherit_parent = FALSE,
  labels = TRUE
)

`us`	umapscan object to describe clusters
`parent`	name of the parent cluster
`max_level`	get membership at most this level deep
`noise_inherit_parent`	if TRUE, 'Noise' points are given their parent cluster membership
`labels`	if TRUE, use label when possible instead of identifier as cluster names
