Medoid Calculation — medoid • c3t

Determines the medoid of one or several subsets of elements using a distance matrix.

Usage

medoid(distances, byName = FALSE)

medoids_partition(distances, partition, clusters = NULL)

Arguments

distances: The distance matrix used to find the medoid(s) (distance matrix).
byName: TRUE if the returned result should be the row name corresponding to the medoid, FALSE if it should be the row number. Ignored if distances is not named. (flag)
partition: The partition for which the medoids of each cluster should be determined (vector).
clusters: The set of clusters for which the medoid should be calculated (all by default).

Value

For medoid: depending on byName, the name or the identifier of the medoid.

For medoids_partition: a named numeric vector indicating, for each cluster or a subset of them, the identifier of its medoid.

Functions

medoid(): Determine the medoid of a set.
medoids_partition(): Calculation of the medoid for each cluster in a partition.

Examples

M <- matrix(c(0.0, 1.0, 2.0,
              1.0, 0.0, 3.0,
              2.0, 3.0, 00.))

medoid(M)
