rotate {spatstat} | R Documentation |
Applies a rotation to any two-dimensional object, such as a point pattern or a window.
rotate(X, angle=pi/2)
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. |
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.
Another object of the same type, representing the
result of rotating X
through the specified angle.
