  "Description": "Provides access to geocomputing and terrain analysis\nfunctions of the geographical information system (GIS) 'SAGA'\n(System for Automated Geoscientific Analyses) from within R by\nrunning the command line version of SAGA. This package\nfurthermore provides several R functions for handling ASCII\ngrids, including a flexible framework for applying local\nfunctions (including predict methods of fitted models) and\nfocal functions to multiple grids. SAGA GIS is available under\nGPL-2 / LGPL-2 licences from\n<https://sourceforge.net/projects/saga-gis/>.",
