RagraphBPH-class: Class "RagraphBPH"

In hyperdraw: Visualizing Hypergaphs

Description

The purpose of this class is to represent a laid out version of a graphBPH object. The laying out is performed by the Rgraphviz package. This is an intermediate step in the process of drawing a graphBPH object.

Objects from the Class

Objects of this class should be created via the graphLayout() function.

Slots

graph:

Object of class Ragraph. The laid out graph.

allNodes:

Object of class character. The names of all nodes in the graph.

nodes:

Object of class character. Records normal nodes in the graph.

edgeNodes:

Object of class character. Records edge-nodes in the graph.

edgeNodeIO:

Object of class list. Records which edges enter and exit each edge-node.

Methods

plot

signature(x = "RagraphBPH", y = "ANY"): draw a representation of the hypergraph where edges between normal nodes in the graph pass through an intermediate edge-node in a nice smooth curve.

edgeDataDefaults<-

signature(self = "RagraphBPH", attr = "character", value = "ANY"): set the default drawing attributes for all edges.

edgeData<-

signature(self = "RagraphBPH", from = "character", to = "character", attr = "character", value = "ANY"): set a specific drawing attribute for one or more edges.

nodeDataDefaults<-

signature(self = "RagraphBPH", attr = "character", value = "ANY"): set the default drawing attributes for all nodes.

nodeData<-

signature(self = "RagraphBPH", n = "character", attr = "character", value = "ANY"): set a specific attribute for one or more nodes.

graphDataDefaults<-

signature(self = "RagraphBPH", attr = "character", value = "ANY"): set the default drawing attributes for the graph.

graphData<-

signature(self = "RagraphBPH", n = "character", attr = "character", value = "ANY"): set a specific attribute for the graph.
