dg.BlockEdge-class: Class dg.BlockEdge

Description Details Slots Extends Methods Note Author(s) See Also Examples

Description

The class for edges between blocks and for edges between vertices and blocks.

Details

The function is used in returnBlockEdgeList. dynamicGraphMain will automatic update block edges when vertices are moved between blocks.

Slots

oriented:

Object of class "logical", see "dg.VertexEdge".

vertex.indices:

Object of class "numeric", see also "dg.Edge". Vector with abs(vertex.indices) the indices of the nodes of the block edge. If the index is positiv then the node is a vertex, else it is a block.

width:

Object of class "numeric", see "dg.Edge".

dash:

Object of class "character", see "dg.Edge".

color:

Object of class "character", see "dg.Edge".

label:

Object of class "character", see "dg.Edge".

label.position:

Object of class "numeric", see "dg.Edge".

Extends

Class "dg.Edge", directly. Class "dg.Node", directly.

Methods

nodeTypesOfEdge

signature(object = "dg.BlockEdge"): Extract the types ("super classes": "Vertex" or "Block") of the vertices (nodes) of the edge.

oriented<-

signature(x = "dg.BlockEdge"): ...

oriented

signature(object = "dg.BlockEdge"): ...

Note

The methods of dg.Edge also applies for dg.BlockEdge.

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.
