plus vector shift) to a plane geometrical object,
such as a point pattern or a window.
Usage
affine(X, ...)
Arguments
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").
...
Arguments determining the affine transformation.
Value
Another object of the same type, representing the
result of applying the affine transformation.
Details
This is generic. Methods are provided for
point patterns (affine.ppp)
and windows (affine.owin).
