22_GeomArray: Geometric Arrays

In vectools: Advanced Vector Toolkit

Description

A GeomArray is a subclass of ObjectArray for storing GeomObject(s).

Note that GeomArray is also a GeomObject, and contain other GeomArray(s).
i.e. They can be recursive.

NOTE:
INTERNAL STRUCTURE OF OBJECTS IS SUBJECT TO CHANGE.
DO NOT USE SLOTS, DIRECTLY.

Usage

GeomArray (n, ..., D)

GeomArray2 (n)
GeomArray3 (n)

as.GeomArray (v, ..., n, D)

Arguments

n	Single integer, the dimensions. Currently, restricted to one dimensional arrays.
D	Integer, two or three, for the number of spatial dimensions. Any elements in the GeomArray will need to match this. For the as function, D is optional but all elements need to match.
v	A list of GeomObject(s).
...	Ignored.

Value

A GeomObject.

Examples

#explicit construction
v <- GeomArray (2, D=2)
v [[1]] <- regPolygon (6, d=1)
v [[2]] <- regPolygon (6, d=2)
plot (v)

#construction via matrix array multiplication
v <- regPolygon (6, d=1) 
plot (v)
