setBlocks: Class dg.BlockList: The block list

Description

Create a block list with positioning the vertices in the blocks.

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

Usage

setBlocks(block.list, vertices, labels = NULL,  right.to.left = FALSE, nested.blocks = FALSE,  blockColors = NULL, color = "Grey", N = 3)

Arguments

block.list

The list of vectors identifying the blocks. Each item in the list is a vector with of the indices (or text strings for names) of vertices of a block.

vertices

The list of vertices, each containing the class dg.Vertex. Returned with positions set in the interval of the blocks.

labels

List of text strings with the labels of the blocks. If labels is set to NULL then labels are found as names(block.list).

right.to.left

Logical. If right.to.left is set to TRUE then the explanatory blocks are drawn to the right.

nested.blocks

Logical. If nested.blocks then the blocks are drawn nested.

blockColors

Vector of text string with the blockColors of the blocks.

color

Single text string with color of the blocks. Only used when blockColors is not given.

N

Integer, N is the number of coordinates of the vertices and block corners.

Value

A list with components

Blocks

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

Vertices

The list of vertices, with the positions of the vertices updated such the vertices has positions within the blocks.

Slots
