rtor.shift: Random toroidal shift on a point data set

Description

Perform a random toroidal shift on a point data set

Usage

rtor.shift(pts,rect)

Arguments

pts

The point data set to shift

rect

A rectangle defining the region for the toroidal map. If not given, the bounding box of pts is used.

Value

A point data set like pts, but after application of a random toroidal shift along the x and y axes.

Details

The planar region defined by rect is assumed connected at its top and bottom edges, and at its left and right sides. A random shift is applied to the points and the resulting set of points returned.
