Classes dist, ar_cross_dissimilarity and ar_similarity — Proximity Matrices

Simple classes to represent proximity matrices.

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.

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.
