anyGraph-class: Class "anyGraph"
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
