Classes dist, ar_cross_dissimilarity and ar_similarity — Proximity Matrices
Description
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.
