dg.ExtraEdge-class {dynamicGraph} | R Documentation |
The class for the edges between vertices and extra vertices.

If the index is positiv then the node is a vertex,
else it is the extra vertex. width

signature(object = "dg.ExtraEdge")
:
Extract the types ("super classes": "Vertex"
or "Extra"
)
of the vertices (nodes) of the edge.
The methods (except oriented
) of dg.Edge
also applies for dg.ExtraEdge
.
The method new
also accepts the argument vertices
or
vertexList
. The label
is then extracted from these vertices.
The length of vertices
should match vertex.indices
, where
vertex.indices
is used to select vertices form vertexList
.
Extra vertices and nodes are used in demo(dg.USArrests)
to display the loadings in a biplot.
