newBlock: The block object

Description

Returns an object of class BlockProto.

Usage

newBlock(stratum = 0, index = 0, position = matrix(rep(0, 6), ncol = 3),
         closed = FALSE, visible = TRUE, color = "Grey", label = "Label",
         label.position = c(0, 0, 0), ancestors = NULL)

Arguments

stratum

Integer for the stratum of the block.

index

Integer for the index of the block.

position

Numeric vector for the position of the block, the two diagonal opposite corners.

closed

Logical, if TRUE then the block is drawn as a "vertex".

visible

Logical, if TRUE then the block is drawn.

color

Text string for the color of the block.

label

Text string for the label of the block.

label.position

Numeric vector for the label.position of the block label.

ancestors

Integer vector for the ancestor blocks of the block. The slot with the descendant blocks is set after the creation of the block.

Value

• A object of class BlockProto.
