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.
