newFactorEdge: The factor edge object

Description

Returns an object of the class FactorEdgeProto for an edge from a vertex to a factor node in the bipartite graph.

Usage

newFactorEdge(node.indices, nodes = NULL, width = 2,
              color = "DarkOliveGreen", type = NULL,
              label = ifelse(is.null(nodes), "",
                             paste(Labels(nodes), collapse = "~")))

Arguments

node.indices

Vector with abs(node.indices) the indices of the nodes of the factor edge. If the index is positiv then the node is a vertex, else it is the factor vertex.

nodes

List with the nodes of the factor edge. Used for setting the default label.

width

Numeric for the width of the factor edge.

color

Text string with the color of the factor edge.

type

Text string with the type of the factor edge.

label

Text string with the label of the factor edge.

Value

• A object of class FactorEdgeProto.
