Description

Applies a vector shift to a point pattern.

Usage

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

Arguments

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

Value

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

Run this code
data(cells)
  X <- shift(cells, c(2,3))

  Y <- superimpose(cells, shift(cells, c(0.1,0.1)))
  plot(Y)
