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.
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.
