In fpc: Flexible Procedures for Clustering

Extracting intersections between clusters from fpc-object

Description

Extracts the information about the size of the intersections between representative Fixed Point Clusters (FPCs) of stable groups from the output of the FPC-functions fixreg and fixmahal.

Usage

simmatrix(fpcobj)

Arguments

fpcobj

an object of class rfpc or mfpc.

Value

A non-negative real-valued vector giving the number of points in the intersections of the representative FPCs of stable groups.

Note

The intersection between representative FPCs no. i and j is at position sseg(i,j).
