Applies a vector shift of the plane to a geometrical object, such as a point pattern or a window.
shift(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 shift vector.
Another object of the same type, representing the result of applying the shift.
This is generic. Methods are provided for
point patterns (shift.ppp)
and windows (shift.owin).
The object is translated by the vector vec.
