rotate: Rotate

Description

Applies a rotation to any two-dimensional object, such as a point pattern or a window.

Usage

rotate(X, angle=pi/2)

Arguments

X

Any suitable dataset representing a two-dimensional object, such as a point pattern (object of class "ppp"), or a window (object of class "owin").

angle

Angle of rotation.

Value

• Another object of the same type, representing the result of rotating X through the specified angle.

synopsis

rotate(X, ...)

Details

This is generic. Methods are provided for point patterns (rotate.ppp) and windows (rotate.owin).

The angle of rotation is measured in radians, anticlockwise, and the centre of rotation is the origin.

Examples

library(spatstat)
  data(cells)
  X <- rotate(cells, pi/3)
  plot(X)
  plot(rotate(cells$window, pi/4))
