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 image (object of class "im").

...

Arguments determining the affine transformation.

Details

This is generic. Methods are provided for point patterns (affine.ppp) and windows (affine.owin).

Value
