+% Mission %
+\begin{minipage}{\linewidth}

+   \textbf{\fontsize{44}{44}\selectfont \textbf{Misión}}\vspace{8pt}\\ 
+   El objetivo de qgisprocess es proporcionar una interfaz de R para los algoritmos de geoprocesamiento de QGIS, un popular programa de sistema de información geográfica (SIG) de código abierto. Este paquete es una reimplementación de la funcionalidad proporcionada por el paquete archivado \textbf{RQGIS} o la que parcialmente fue revivido en el paquete \textbf{RQGIS3}

+% Features %

+Este paquete facilita el uso de algoritmos de procesamiento nativos y algunos de GDAL, GRASS y muchos otros (como SAGA).
