shift: Apply Vector Translation

Description

Applies a vector shift of the plane to a geometrical object, such as a point pattern or a window.

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.

Value

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

synopsis

shift(X, ...)

Details

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

The object is translated by the vector vec.

shift.ppp, shift.owin, rotate, affine

Examples

data(cells)
  X <- shift(cells, c(2,3))
  plot(X)
  # no discernible difference except coordinates are different
