Applies any affine transformation of the plane (linear transformation plus vector shift) to a plane geometrical object, such as a point pattern or a window.
affine(X, ...)Another object of the same type, representing the result of applying the affine transformation.
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 image
(object of class "im").
