multiGraph-class {graph} | R Documentation

## Class "multiGraph"

### Description

A collection of classes to model multigraphs. These include the multiGraph class as well as classes to contain edge sets.

### Objects from the Class

Objects can be created from the `multiGraph` class, the `edgeSet` class is virtual, and particular variants should be used.

### Slots

These slots are for the multiGraph class.

nodes

  The names of the nodes.

edgeL

  A list of edge lists.

nodeData

  An instance of the `attrData` class.

graphData

  A list.

These slots are for the `edgeSet` class, or one of its sublcasses.

edgeData

  An instance of the `attrData` class.

edgemode

  A character vector, one of directed, or undirected.

edgeL

  A list of the edges (graphNEL)

adjMat

  An adjacency matrix (graphAM)

### Methods

show

  Print a multigraph.

isDirected

  A vector indicating which of the edgeSets is directed.

nodes

  Retrieve the node names

numNodes

  Return the number of nodes

edges

  Return either all edges, or a subset of them, depending on the arguments supplied.

numEdges

  Return a vector with the number of edges, for each edge set.
