rotate.ppp: Rotate a Point Pattern

Description

Rotates a point pattern

Usage

## S3 method for class 'ppp':
rotate(X, angle=pi/2, \dots)

Arguments

X

A point pattern (object of class "ppp").

angle

Angle of rotation.

...

Arguments passed to rotate.owin affecting the handling of the observation window, if it is a binary pixel mask.

Value

• Another object of class "ppp" representing the rotated point pattern.

Details

The points of the pattern, and the window of observation, are rotated about the origin by the angle specified. Angles are measured in radians, anticlockwise. The default is to rotate the pattern 90 degrees anticlockwise. If the points carry marks, these are preserved.
