clusterSizes: Number of trajectories per cluster

In philips-software/latrend: A Framework for Clustering Longitudinal Data

Number of trajectories per cluster

Description

Obtain the size of each cluster, where the size is determined by the number of assigned trajectories to each cluster.

Usage

clusterSizes(object, ...)

Arguments

object	The lcModel object.
...	Additional arguments passed to trajectoryAssignments().

Details

The cluster sizes are computed from the trajectory cluster membership as decided by the trajectoryAssignments() function.

Value

A named ⁠integer vector⁠ of length nClusters(object) with the number of assigned trajectories per cluster.
