Description

Re-assigns members of one cluster to another specified cluster, reducing the number of clusters by one.

Usage

1

Arguments

clustering

a vector of (integer) cluster memberships, or an object of class‘partition’, ‘partana’, or ‘clustering’

from

the cluster number to be vacated

to

the cluster to which members will be re-assigned

Details

The function simply renumbers members of one cluster with the number of another, but greatly simplifies managing the list objects class‘partition’, ‘partana’, or ‘clustering’ and simplifes the syntax.

Value

A list object of class ‘clustering’ specifying cluster membership for every object.
