relations (version 0.3-3)

dissimilarity: Dissimilarity Between Relations

Description

Compute the dissimilarity between (ensembles of) relations.

Usage

relation_dissimilarity(x, y = NULL, method = "symdiff", ...)

Arguments

x

an ensemble of relations, or something which can be coerced to such (see relation_ensemble).

y

NULL (default), or as for x.

method

a character string specifying one of the built-in methods for computing dissimilarity, or a function to be taken as a user-defined method. If a character string, its lower-cased version is matched against the lower-cased names of the availabl

...

further arguments to be passed to methods.

Value

• If y is NULL, an object of class dist containing the dissimilarities between all pairs of elements of x. Otherwise, a matrix with the dissimilarities between the elements of x and the elements of y.

Details

Available built-in methods are as follows. Apart from the symmetric difference distance, these are applicable to endorelations only.
