bbox2sp {pedometrics}

Create a Spatial* object from a bounding box

Description

Take the bounding box of a Spatial* object and create a SpatialPoints* or SpatialPolygons* object from it.

Usage

bbox2sp(obj, sp = "SpatialPolygons", keep.crs = TRUE)

Arguments

obj

Object of class Spatial*.

sp

Class of the resulting object with options "SpatialPolygons" (default), "SpatialPoints", "SpatialPointsDataFrame", and "SpatialPolygonsDataFrame".

keep.crs

Logical for assigning the same coordinate reference system to the resulting Spatial* object. Defaults to keep.crs = TRUE.

Value

An object of class SpatialPoints* or SpatialPolygons*.

Dependencies

The sp package, provider of classes and methods for spatial data in R, is required for bbox2sp() to work. The development version of the sp package is available on https://github.com/edzer/sp/ while its old versions are available on the CRAN archive at https://cran.r-project.org/src/contrib/Archive/sp/.

Note

Some of the solutions used to build this function were found in the source code of the R-package intamapInteractive. As such, the authors of that package, Edzer Pebesma [e-mail] and Jon Skoien [e-mail], are entitled ‘contributors’ to the R-package pedometrics.
