diversity_objective {anticlust}  R Documentation 
Compute the diversity for a given clustering.
diversity_objective(x, clusters)
x 
The data input. Can be one of two structures: (1) A data matrix
where rows correspond to elements and columns correspond to
features (a single numeric feature can be passed as a vector). (2)
An N x N matrix dissimilarity matrix; can be an object of class

clusters 
A vector representing (anti)clusters (e.g.,
returned by 
The objective function used in (anti)cluster editing is the
diversity, i.e., the sum of the pairwise distances between elements
within the same groups. When the input x
is a feature
matrix, the Euclidean distance is computed as the basic distance
unit of this objective.
The cluster editing objective
