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.
