Details
The concept is very straightforward but for an all days usage pretty
helpful. You need to provide a terra
or a sf
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.
Examples
run = FALSE
if (run) {
# automatic retrieval of valid 'GRASS GIS' environment settings
# if more than one is found the user has to choose.
paramGRASSw()
# typical OSGeo4W64 installation
paramGRASSw(c("C:/OSGeo4W64","grass-7.0.5","osgeo4W"))
