Usage
shift(X, vec=c(0,0))
Arguments
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").
vec
Vector of length 2 representing a translation.
Details

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

The object is translated by the vector vec.

Value

  • Another object of the same type, representing the result of applying the shift.
