⚠️There's a newer version (1.4.2) of this package.Take me there.

RSAGA (version 0.94-5)

SAGA Geoprocessing and Terrain Analysis in R

Description

Provides access to geocomputing and terrain analysis functions of the geographical information system (GIS) 'SAGA' (System for Automated Geoscientific Analyses) from within R by running the command line version of SAGA. This package furthermore provides several R functions for handling ASCII grids, including a flexible framework for applying local functions (including predict methods of fitted models) and focal functions to multiple grids. SAGA GIS is available under GPLv2 / LGPLv2 licence from http://sourceforge.net/projects/saga-gis/.
