vertexSet-class: Class "vertexSet"

In giRaph: The giRaph package for graph representation in R

Description

Class for vertex sets

Objects from the Class

Objects can be created by calls of the form new("vertexSet", ...) which admit short-hands of the form v(...).

Slots

.Data:

Object of class "vector" storing unique character identifiers that are sintactically valid names

Extends

Class "character", from data part. Class "vector", by class "character".

Methods

initialize

signature(.Object = "vertexSet"): constructs a vertex set from a vector of unique sintactically valid names

show

signature(object = "vertexSet"): displays a vertex set as comma separated characters in graph brackets

areTheSame

signature(x = "vertexSet", y = "vertexSet"): x and y are the same vertex set if they are the same set of character identifiers

[

signature(x = "vertexSet"): extracts a vertex set

coerce

signature(from = "vector", to = "vertexSet"): constructs a vertex set from vector input

names

signature(x = "vertexSet"): gets the character vertex identifiers

+

signature(e1 = "vertexSet", e2 = "vertexSet"): performs the union of two vertex sets

*

signature(e1 = "vertexSet", e2 = "vertexSet"): performs the intersection of two vertex sets

-

signature(e1 = "vertexSet", e2 = "vertexSet"): performs the asymmetric difference of two vertex sets

Warning

The constructor will try to handle any vector input by silently transforming it into a vector of unique sintactically valid names obtained via make.names from the unique input elements.
