hypergraph (version 1.44.0)

DirectedHyperedge-class: Class DirectedHyperedge

Description

This class represents directed hyperedges in a Hypergraph-class. A directed hyperedge consists of two disjount sets of nodes, those in the tail and those in the head of the hyperedge. Directed hyperedges are sometimes called hyperarcs.

Objects from the Class

Objects can be created by calls of the form new("DirectedHyperedge", head, tail, label). You can also use the convenience function DirectedHyperedge.

Slots

tail:

Character vector of nodes in the tail of the hyperedge

head:

Character vector of nodes in the head of the hyperege

label:

Character string describing the directed hyperedge

Extends

Class "Hyperedge", directly.

Methods

head

signature(x = "DirectedHyperedge"): Return a vector containing the nodes in the head of the hyperedge

tail

signature(x = "DirectedHyperedge"): Return a vector containing the nodes in the tail of the hyperedge

initialize

signature(.Object = "DirectedHyperedge"): Create a new instance.

nodes

signature(object = "DirectedHyperedge"): Return a vector containing all nodes present in the hyperedge.

show

signature(object = "DirectedHyperedge"): Print me

toUndirected

signature(.Object = "DirectedHyperedge"): Return a Hyperedge-class object that results from coercing to an undirected hyperedge.
