## The Maronna Data Set

### Description

The Maronna data set.

### Usage

    data(Maronna)

### Value

A list contains a 200 by 2 data matrix and a 200 by 1 cluster membership vector. There are 4 equally distributed clusters in a two-dimensional space. The first cluster consists of the first 50 data points, the second cluster corresponds to the next 50 data points and so on.

### Note

We generated this data set by using the models and parameter settings described in Maronna and Jacovkis (1974).

### Examples

        data(Maronna)
        # data matrix
        maronna <- Maronna$maronna

        # cluster membership
        maronna.mem <- Maronna$maronna.mem
        # 'true' number of clusters
        nClust <- length(unique(maronna.mem))

        # scatter plots
        plotClusters(maronna, maronna.mem)
