findGRASS function

Returns attributes of valid 'GRASS GIS' installation(s) on the system.

Retrieve a list of valid 'GRASS GIS' installation(s) on your system. There is a big difference between osgeo4W and stand_alone installations. The function tries to find all valid installations by analyzing the calling batch scripts.

Arguments

• searchLocation: Location to search for the grass executable, i.e. one executable for each GRASS installation on the system. For Windows systems it is mandatory to include an uppercase Windows drive letter and a colon. Default for Windows systems is C:/, for Linux systems the default is /usr/bin.
• ver_select: boolean, Default is FALSE. If there is more than one 'GRASS GIS' installation and ver_select = TRUE, the user can interactively select the preferred 'GRASS GIS' version.
• quiet: boolean, default is TRUE. switch to suppress console messages

Returns

data frame with the 'GRASS GIS' binary folder(s) (i.e. where the individual individual GRASS commands are installed), version name(s) and installation type code(s)

Examples

# find recursively all existing 'GRASS GIS' installation folders starting 
# at the default search location
