In aczepielik/CrossTabCluster: Tools For Clsutering Cross Tables

Description

Quantifies clustering quailty comparing it to siumulated clusters. See Section 4.1 of the thesis for further details.

Usage

dimension	integer. Whether to use rows (1) or columns (2). Default is 1.
clusters	list of integer vectors. Each vector should define a cluster by specifing row or column indices of its memebrs. Clusters must not overalap.
