Description

Applies a vector shift to a point pattern.

Usage

 ## S3 method for class 'ppp':
 shift(X, vec=c(0,0), ...)

Arguments

Details

The point pattern, and its window, are translated by the vector vec.

  X <- shift(cells, c(2,3))
  ## Not run: 
  plot(X)
  # no discernible difference except coordinates are different
  
## End(Not run)
  plot(cells, pch=16)
  plot(shift(cells, c(0.03,0.03)), add=TRUE)
