simmatrix {fpc} | R Documentation

## 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)`.
