proximity-classes: Classes dist, ar_cross_dissimilarity and ar_similarity --- Proximity Matrices

Description

Simple classes to represent proximity matrices.

Arguments

Objects from the Class

dist objects are the result of calling the method dissimilarity() with one argument or any R function returning a S3 dist object.

ar_cross_dissimilarity objects are the result of calling the method dissimilarity() with two arguments, by calls of the form new("similarity", ...), or by coercion from matrix.

ar_similarity objects are the result of calling the method affinity(), by calls of the form new("similarity", ...), or by coercion from matrix.

Details

For compatibility with clustering functions in R, we represent dissimilarities as the S3 class dist. For cross-dissimilarities and similarities, we provide the S4 classes ar_cross_dissimilarities and ar_similarities.
