Merge Specified Clusters in a Classification
Re-assigns members of one cluster to another specified cluster, reducing the number of clusters by one.
mergeclust(clustering,from,to)
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 |
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.
A list object of class ‘clustering’ specifying cluster membership for every object.
