Description

computes the AGNES coefficient of a graph structure.

Usage

1
2

Arguments

A

matrix or Matrix object with adjacency matrix of a graph.

Details

The input of the AGNES hierarchical algorithm is the dissimilarity matrix of the graph structure A computed by graphCorr. Then the R function agnes is used to calculate the coefficient.

Value

AGNES coefficient magnitude for the given graph structure.
