<code>GRaster</code>s and <code>GVector</code>s are R objects that contain a pointer to a raster or vector in GRASS. Thus, for a <code>GRaster</code> or <code>GVector</code> to be functional, the GRASS file must exist. This function indicates if that is so.

internal

Processing of large-in-memory/large-on disk rasters and spatial
vectors using 'GRASS' <https://grass.osgeo.org/>. Most functions in the
'terra' package are	recreated. Processing of medium-sized and smaller
spatial objects will nearly always be faster using 'terra' or 'sf', but
for large-in-memory/large-on-disk objects, 'fasterRaster' may be faster.
To use most of the functions, you must have the stand-alone version (not
the 'OSGeoW4' installer version) of 'GRASS' 8.0 or higher.
