Usage
affine(X, ...)Arguments
- X
- Any suitable dataset representing a two-dimensional
object, such as a point pattern (object of class
"ppp"), a line segment pattern (object of class"psp"), a window (object of class"owin") or a pixel im - ...
- Arguments determining the affine transformation.
Details
This is generic. Methods are provided for
point patterns (affine.ppp)
and windows (affine.owin).
Value
- Another object of the same type, representing the result of applying the affine transformation.
