returnBlockEdgeList: Class dg.BlockEdgeList: The block edge list

Description Usage Arguments Value Slots Extends Methods Note Author(s) Examples

Description

Return a list of block edges, each of class dg.BlockEdge.

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

Usage

returnBlockEdgeList(edge.list, vertices, blocks, 
                    visibleBlocks = 1:length(blocks), width = 2, 
                    color = "default", N = 3, oriented = NA, type = NULL) 

Arguments

edge.list

A list of vectors identifying the edges (between vertices). 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.

blocks

The list of blocks, each of a class dg.Block.

visibleBlocks

A numeric vector with the indices of the visibleBlocks. The argument is for view where some blocks are not visible in the view, but the vertices of the blocks are drawn.

width

A numeric with the initial width of block edges.

color

"default", or list with one or two text strings for colors giving the initial color of block edges. The two colors are used for respectively edges between blocks and for edges between blocks and vertices.

N

Integer, N is the number of coordinates of the vertices.

oriented

Logical, if TRUE then the edges are oriented.

type

A text string giving the type of block edges.

Value

A list of block edges, each of class dg.BlockEdge.

Slots

.Data:

Object of class "list".

Extends

Class "dg.EdgeList", directly. Class "dg.list", directly. Class "list", from data part. Class "dg.NodeList", by class "dg.EdgeList". Class "vector", by class "dg.EdgeList". Class "vector", by class "dg.list". Class "vector", by class "list".

Methods

initialize

signature(.Object = "dg.BlockEdgeList"): ...

ancestorsBlockList

signature(blockList = "dg.BlockList"): ...

descendantsBlockList

signature(blockList = "dg.BlockList"): ...

checkBlockList

signature(blockList = "dg.BlockList"): ...

Note

The methods of the edge list, returnEdgeList, also applies for block edge lists.
