get_cut_from_merge_id: Get clustering of leaves from merge_id

In protoshiny: Interactive Dendrograms for Visualizing Hierarchical Clusters with Prototypes

Get clustering of leaves from merge_id

Description

This function expects a set of node id's of a hierarchical clustering object that would define a partition of the leaves. It returns a vector giving the implied clustering of the leaves (analogous to the output of 'stats::cutree').

Usage

get_cut_from_merge_id(hc, merge_id)

Arguments

hc

An object of class 'hclust'

merge_id

A numeric vector. Indexing of nodes should match that of the 'merge' matrix in an 'hclust' object. In particular, positive numbers specify interior nodes and negative numbers specify leaves. These nodes must define a partition of the leaves, meaning no node in 'merge_id' should be a descendant of another and every leaf should either be included directly or be the descendant of one of the interior nodes referenced by 'merge_id'.
