n_of_objects {clue}

Number of Objects in a Partition or Hierarchy

Description

Determine the number of objects from which a partition or hierarchy was obtained.

Usage

n_of_objects(x)

Arguments

x

an R object representing a (hard of soft) partition or a hierarchy of objects, or dissimilarities between objects.

Details

This is a generic function.

The methods provided in package clue handle the partitions and hierarchies obtained from clustering functions in the base R distribution, as well as packages RWeka, ape, cba, cclust, cluster, e1071, flexclust, flexmix, kernlab, mclust, movMF and skmeans (and of course, clue itself).

There is also a method for object dissimilarities which inherit from class "dist".

Value

An integer giving the number of objects.
