rotate.psp: Rotate a Line Segment Pattern

Description

Rotates a line segment pattern

Usage

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

Arguments

X
A line segment pattern (object of class "psp").
angle
Angle of rotation.
...
Ignored.

Value

  • Another object of class "psp" representing the rotated line segment pattern.

Details

The line segments 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 line segments carry marks, these are preserved.

Rotation of binary image masks is not yet implemented.

  X <- psp(runif(10), runif(10), runif(10), runif(10), window=owin())
  plot(X, main="original")
  Y <- rotate(X, pi/4)
  plot(Y, "rotated")
  par(oldpar)
