| returnEdgeList {dynamicGraph} | R Documentation |
Return a list of edges, each of class containing dg.VertexEdge.
Objects can be created by calls of the form new("dg.VertexEdgeList", ...).
returnEdgeList(edge.list, vertices, width = 2, color = "DarkSlateGrey", N = 3,
oriented = NA, types = NULL, edgeClasses = validEdgeClasses())
edge.list |
A list of vectors identifying the edges.
Each vector of edge.list should be a vector of
integers giving the indices of the vertices of an edge, or
a vector of text strings with the names of the vertices. |
vertices |
The list of vertices,
each of a class containing dg.Vertex.
vertices are used to set the initial labels of the edges. |
width |
A single numeric with the initial width of the edges. |
color |
A single text string giving the color of the edges. |
oriented |
Logical, if TRUE then the edges are oriented. |
types |
A vector of text strings giving the types of the edges,
identify which classes the edges should be of,
containing the dg.VertexEdge.
|
N |
Integer, N is the number of coordinates of the vertices. |
edgeClasses |
Returned value from validEdgeClasses,
or extension of this matrix. |
A list of edges, each of class containing dg.VertexEdge.

Beside the methods of the vertex list, vertexList,
(except Positions, Indices
and Strata) the edge list also has the methods
NodeTypes,
