+`link2gi` provides functions that make it a bit easier to connect most of the common open source GI software packages to the R-biotop in a straightforward way. It supports both the use of wrapper packages and the direct use via system calls. It focuses on `Linux` and `WindowsX` operating systems but nevertheless it should also work with `OSX`.
 
 To utilize the power of the open source GI tools from within `R` you need to install  them first. As a first promising opportunity to do fullfil most of the requirements you may install `QGIS, GRASS`- and `SAGA-GIS` following the excellent [installation instructions](https://github.com/jannes-m/RQGIS/blob/master/vignettes/install_guide.Rmd)  of the [RQGIS](https://cran.r-project.org/web/packages/RQGIS/index.html) package will have a good first try to ensure a smooth working environment. Note: for most of the cases you may use just `RQGIS` as wrapper for the `QGIS` related functionality.
