dynamicGraph (version 0.2.2.6)

dg.graphedges-class: Class dg.graphedges

Description

The representation of a graph for dynamicGraph. Vertices, blocks, viewType, edges, etc. are here the dynamicGraph objects.

Arguments

Objects from the Class

Objects can be created by calls of the form new("dg.graphedges", ...).

Slots

viewType:
Object of class "character" with the type of view.
visibleVertices:
Object of class "numeric": Numeric vector of the indices of the vertices of vertexList to plot.
visibleBlocks:
Object of class "numeric": Numeric vector of the indices of the blocks of blockList to plot.
oriented:
Object of class "logical": If TRUE (or FALSE) then edges are oriented (or not), also when blocks are missing. If NA then the edges are directed according to the blocks of the edge.
edgeList:
Object of class "dg.VertexEdgeList": List of edges (of class containing dg.Edge) created by returnEdgeList or exported from dynamicGraphMain.
blockEdgeList:
Object of class "dg.BlockEdgeList": List of blockedges (of class containing the class dg.BlockEdge) created by returnBlockEdgeList or exported from dynamicGraphMain.
factorVertexList:
Object of class "dg.FactorVertexList": List of secondary vertices, called factor vertices, for, e.g., the generators of the model, (each of class containing dg.FactorVertex) created by returnFactorVerticesAndEdges or exported from dynamicGraphMain.
factorEdgeList:
Object of class "dg.FactorEdgeList": List of bipartite graph edges, called factor edges, (each of class containing dg.FactorEdge) created by the function returnFactorEdgeList or exported from dynamicGraphMain. Factor edges are edges between vertices and factor vertices.
extraList:
Object of class "dg.VertexList": List of vertices (of class containing the class dg.Vertex) created by the function returnVertexList or exported from the function dynamicGraphMain, for, e.g., additional titles in the plot.
extraEdgeList:
Object of class "dg.ExtraEdgeList": List of edges between extra vertices and vertices.
