Apply Vector Translation To Point Pattern

Applies a vector shift to a point pattern.

Keywords: spatial

Usage

shift.ppp(X, vec=c(0,0), ...)

Arguments

X: Point pattern (object of class "ppp").
vec: Vector of length 2 representing a translation.
...: Ignored

Details

The point pattern, and its window, are translated by the vector vec. This is a method for the generic function shift.

Value

Another point pattern (of class "ppp") representing the result of applying the vector shift.

Examples

data(cells)
  X <- shift(cells, c(2,3))
  plot(X)
  # no discernible difference except coordinates are different
  Y <- superimpose(cells, shift(cells, c(0.1,0.1)))
  plot(Y)
