Rotate a Line Segment Pattern
Description
Rotates a line segment pattern
Usage
## S3 method for class 'psp'
rotate(X, angle=pi/2, ..., centre=NULL)
Arguments
X |
A line segment pattern (object of class |
angle |
Angle of rotation. |
... |
Arguments passed to |
centre |
Centre of rotation.
Either a vector of length 2, or a character string
(partially matched to |
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.
Value
Another object of class "psp"
representing the
rotated line segment pattern.
