directedEdge-class: Class "directedEdge"

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

Description

Class for directed edges

Objects from the Class

Objects can be created by calls of the form new("directedEdge", ...) which admit short-hands of the form d(...) and r(...).

Slots

.Data:

Object of class "list" storing strictly positive numbers that refer to a given "vertexSet" object

Extends

Class "edge", directly. Class "list", from data part. Class "vector", by class "list".

Methods

initialize

signature(.Object = "directedEdge"): constructs a directed edge from a list of strictly positive integers

show

signature(object = "directedEdge"): displays a directed edge as an ordered sequence of undirected edges joined by arrows (using numeric codes)

showRel

signature(object = "directedEdge",code="vertexSet"): displays a directed edge as an ordered sequence of undirected edges joined by arrows (using character names

areTheSame

signature(x = "directedEdge", y = "directedEdge"): x and y are the same directed edge if they are the same ordered sequence of undirected edges

[

signature(x = "directedEdge"): extracts a directed edge

[[

signature(x = "directedEdge"): extracts an undirected edge

card

signature(object= "directedEdge"): counts all vertices in a directed edge

coerce

signature(from = "vector", to = "directedEdge"): constructs a directed edge from vector input

coerce

signature(from = "undirectedEdge", to = "directedEdge"): directs an undirected edge

maxId

signature(x="directedEdge"): gets the maximum numeric identifier of a directed edge

recode

signature(object="directedEdge",src = "vertexSet", dst = "vertexSet"): recodes a directed edge by making its numbers refer to another "vertexSet" object

Warning

The constructor will try to handle any vector input by silently transforming it into a list of strictly positive integers.
