clustergram.vegclust: Vegclust function for clustergram

Description

Vegclust function for clustergram

Usage

clustergram.vegclust(Data, k, method = method, ...)

Arguments

Data

Should be a scales matrix. Where each column belongs to a different dimension of the observations.

k

Number of desired groups for the FCM clustering.

method

Clustering method for the vegclust function.

...

Additional parameters to be passed to the vegclust function.

Value

A list containing the cluster vector and the centers matrix (see vegclust function).

Details

This is an implementation of Fuzzy c-means clustering (with the vegclust function of the vegclust package) for the clustergram function. The return list is internally used by the clustergram to build the clustergram plot.
