hclass: Classifications from Hierarchical Agglomeration

Description

Determines the classifications corresponding to different numbers of groups given merge pairs from hierarchical agglomeration.

Usage

hclass(hcPairs, G)

Arguments

hcPairs
A numeric two-column matrix in which the ith row gives the minimum index for observations in each of the two clusters merged at the ith stage of agglomerative hierarchical clustering.
G
An integer or vector of integers giving the number of clusters for which the corresponding classfications are wanted.

Value

  • A matrix with length(G) columns, each column corresponding to a classification. Columns are indexed by the character representation of the integers in G.
