All aRT geometric data belongs to class aRTgeometry. 


Objects of class aRTgeometry can be plotted and inserted in layers.

aRT supports four types of geometry: points, polygons, lines and raster.

\describe{
\item[points:] Object of the aRTlayer class.
\item[polygons:] Each one ends with the same point that it started. This way, one
object can have more than one polygon and it can be stored in the same position.
\item[lines:] a
\item[raster:] Raster data are represented as matrix.
