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