incidence {relations} | R Documentation |
Determine the incidences of a relation.
relation_incidence(x, ...)
x |
an object inheriting from class |

Further arguments passed to the labeling function used for creating the dimnames of the incidence matrix. |
For a k-ary relation, a k-dimensional numeric array with
values in the unit interval inheriting from class
relation_incidence
whose elements give the memberships of the
corresponding k-tuples are contained in the relation (for a
crisp relation, a binary (0/1) array with elements indicating whether
the corresponding tuples are contained in the relation or not).
