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)

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.

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.
