Attention RQGIS users
« on: September 17, 2019, 05:17:49 PM »
RQGIS establishes an interface between R and QGIS, i.e., it allows the user to access QGIS functionalities from within R. It achieves this by establishing a tunnel to the Python QGIS API via the reticulate-package. This provides the user with an extensive suite of GIS functions, since QGIS allows you to call native as well as third-party algorithms via its processing framework (see also https://docs.qgis.org/2.14/en/docs/user_manual/processing/index.html). Third-party providers include among others GDAL, GRASS GIS, SAGA GIS, the Orfeo Toolbox, TauDEM and tools for LiDAR data. RQGIS brings you this incredibly powerful geoprocessing environment to the R console.
Please check also out our paper presenting RQGIS in detail:

The main advantages of RQGIS are:
 
  • It provides access to QGIS functionalities. Thereby, it calls Python QGIS API but R users can stay in their programming environment of choice without having to touch Python.
  • It offers a broad suite of geoalgorithms making it possible to solve most GIS problems.
  • R users can use just one package (RQGIS) instead of using RSAGA and rgrass7 to access SAGA and GRASS functions. This, however, does not mean that RSAGA and rgrass7 are obsolete since both packages offer various other advantages. For instance, RSAGA provides many user-friendly and ready-to-use GIS functions such as rsaga.slope.asp.curv() and multi.focal.function().
