numClust: Number of Clusters in a Partition or List of Partitions

Description

Computes the number of clusters (unique groups) in a partition or a list of partitions.

Usage

numClust(clu)

Value

An integer (if `clu` is a single partition) or a vector of integers (if `clu` is a list), representing the number of clusters in each partition.

Arguments

clu

A vector representing a partition or a list of such vectors (partitions). Each partition is expected to be a vector of cluster memberships.

Details

If a single vector is provided, it returns the number of unique cluster labels. If a list of partitions is provided (e.g., when dealing with multiple sets of units), it returns a vector of the number of clusters for each partition in the list.

Examples

# Single partition
numClust(c(1, 1, 2, 2, 3))  # returns 3

# List of partitions
numClust(list(c(1, 1, 2), c(1, 2, 3, 4)))  # returns c(2, 4)
