## Relation Incidences

### Description

Determine the incidences of a relation.

### Usage

    relation_incidence(x, ...)

### Arguments

`x` | an object inheriting from class `relation`.
`...` | Further arguments passed to the labeling function used for creating the dimnames of the incidence matrix.

### Value

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).

### See Also

`relation()`; `relation_incidence<-()` for modifying the incidences.

### Examples

    R <- as.relation(c(A = 1, B = 2, C = 3))
    relation_incidence(R)
