GRASS "location" of an object or the active session

Source: R/location.r, R/locationDelete.r
location.Rd

GRASS "projects" or "locations" are sets of one or more rasters and/or vectors with the same coordinate reference systems, and may or may not represent the same actual location on Earth. GRASS "mapsets" are like sub-folders of locations, and are collections of rasters and/or vectors typically related to the same general project. Typical users will not need to make changes to the default location (called "location") or mapset (called "PERMANENT"). See vignette("projects_mapsets", package = "fasterRaster").

This function deletes a GRASS "project"/"location", rasters, and vectors therein. This function should be used cautiously and is mainly of use to developers. See vignette("projects_mapsets", package = "fasterRaster").

Usage

# S4 method for class 'GLocation'
.location(x)

# S4 method for class 'missing'
.location(x)

.locationDelete(location, mapset = NULL, workDir = NULL)

Arguments

x

Either:

  • Missing: Reports location of currently active project/location.

  • A GLocation object or an object that contains the GLocation class (i.e., a GSpatial object: a GRaster or GVector).

location

Character: Name of the GRASS "location".

mapset

Character or NULL (default): Name of the mapset to delete. If NULL, then all mapsets in the given "location" will be deleted.

workDir

Character: Either NULL (default) or a character string of the directory in which the location to be removed resides. If NULL, then the working directory will be obtained from faster("workDir").

Value

A character string.

If successful, TRUE (invisibly). If not, then FALSE (also invisibly), plus a warning.
