anyGraph-class: Class "anyGraph"

In ClausDethlefsen/giRaph: The giRaph package for graph representation in R

Description

A class for graphs of any kind.

Objects from the Class

Objects can be created by calls of the form new("anyGraph", ...). An anyGraph object consists of a single slot (incidenceList) for the only possible representation.

Slots

incidenceList:

Object of class "incidenceList"

Methods

initialize

signature(.Object="anyGraph"): constructs any graph from incidence list representation

show

signature(object = "anyGraph"): displays the available representations of any graph

display

signature(x = "anyGraph"): static graphical representation via package 'mathgraph'

dynamic.Graph

signature(object = "anyGraph"): dynamic graphical representation via package 'dynamicGraph'

incidenceList<-

signature(x = "anyGraph"): sets the incidence list representation

incidenceList

signature(object = "anyGraph"): gets the incidence list representation

names

signature(x = "anyGraph"): gets the character vertex identifiers of any graph

names<-

signature(x = "anyGraph"): sets the character vertex identifiers of any graph

card

signature(object = "anyGraph"): returns the number of vertices and the total number of edge occurrences in any graph

isEmpty

signature(object = "anyGraph"): a graph object is empty if all its possible representations are empty

isPresent

signature(el = "edge", ou = "anyGraph"): an edge occurs in a graph object if it occurs in its non-empty slots

areTheSame

signature(x = "anyGraph", y = "anyGraph"): x and y are the same if their non-empty slots represent the same graph

[

signature(x = "anyGraph"): extracts an induced subgraph

[[

signature(x = "anyGraph"): extracts the character identifier of a vertex

coerce

signature(from = "generalGraph", to = "anyGraph"): no edges are lost in the conversion to the most general class of graphs

coerce

signature(from = "multiGraph", to = "anyGraph"): no edges are lost in the conversion to the most general class of graphs

coerce

signature(from = "simpleGraph", to = "anyGraph"): no edges are lost in the conversion to the most general class of graphs

coerce

signature(from = "anyGraph", to = "dg.graph"): conversion to class 'dg.graph' of package 'dynamicGraph'

+

signature(e1 = "anyGraph", e2 = "vertexSet"): adds a vertex set to any graph by making the new vertices isolated

-

signature(e1 = "anyGraph", e2 = "vertexSet"): removes a vertex set from any graph by dropping all edges involving the vertex set

+

signature(e1 = "anyGraph", e2 = "edge"): adds an edge to any graph

-

signature(e1 = "anyGraph", e2 = "edge"): removes an edge from any graph

*

signature(e1 = "anyGraph", e2 = "vertexSet"): restricts any graph to a vertex set by dropping all edges involving vertices outside the vertex set

Note

Graphical representation via package 'dynamicGraph' is based on coercion to class dg.graph. Coercion to class dg.graph is implemented via coercion to class generalGraph. Graphical representation via package 'mathgraph' is obtained by means of coercion to class simpleGraph.
