RQGIS3: Integrating R with QGIS3

#' @title RQGIS3: Integrating R with QGIS3
#' @description RQGIS3 establishes an interface between R and 'QGIS3', i.e. it
#'   allows the user to access 'QGIS3' functionalities from the R console. It
#'   achieves this by using the 'QGIS3' Python API via the command line. Hence,
#'   RQGIS3 extends R's statistical power by the incredible vast
#'   geo-functionality of 'QGIS' (including also 'GDAL', 'SAGA'- and 'GRASS'-GIS
#'   among other third-party providers). This in turn creates a powerful
#'   environment for advanced and innovative (geo-)statistical geocomputing.
#'   'QGIS' is licensed under GPL version 2 or greater and is available from
#'   <http://www.qgis.org/en/site/>. Before running RQGIS3 you need to make sure
#'   to have installed correctly all external software such as QGIS, GRASS and
#'   SAGA.
#' @details Our vignette helps to correctly install all third-party
#'   dependencies (e.g., QGIS, GRASS, SAGA):\cr\cr
#'   `vignette("install_guide", package = "RQGIS3")` \cr\cr
#'   To get started with RQGIS3, have a peak at the example on our github
