set_default_GRASS |
default = NULL forces a full search for 'GRASS GIS' binaries. You may alternatively provide a vector containing pathes and keywords. c("C:/OSGeo4W64","grass-7.0.5","osgeo4w") is valid for a typical osgeo4w installation. |

The concept is very straightforward but for an all days usage pretty
helpful. You need to provide a raster
or a sp
object. The derived properties are used to initialize a temporary but static
rgrass environment. During the rsession you will have full access to
GRASS7 both via the wrapper package as well as the command line. paramGRASSw initializes the usage of GRASS7.
