shift.ppx: Apply Vector Translation To Box Or Point Pattern In Arbitrary Dimension

Description

Applies a vector shift to a box or point pattern in arbitrary dimension (object of class "boxx" or "ppx").

Usage

# S3 method for boxx
shift(X, vec= 0, …)
 # S3 method for ppx
shift(X, vec = 0, …, spatial = TRUE, temporal = TRUE, local = TRUE)

Arguments

X

Box or point pattern in arbitrary dimension (object of class "boxx" or "ppx").

vec

Either a single numeric or a vector of the same length as the dimension of the spatial and/or temporal and/or local domain.

…

Ignored

spatial,temporal,local

Logical to indicate whether or not to shift this type of coordinates for the ppx method.

Value

For shift.boxx, another "boxx" object and for shift.ppx another "ppx" object. In both cases the new object represents the result of applying the vector shift.

Details

This is a method for the generic function shift.

Examples

# NOT RUN {
  vec <- c(2,3)
  dom <- boxx(c(0,1), c(0,1))
  X <- ppx(coords(cells), domain = dom)
  shift(dom, vec)
  Xs <- shift(X, vec)
  Xs
  head(coords(X), n = 3)
  head(coords(Xs), n = 3)
