argument for nested functions:

This is a wrapper function of tmap
and hence displays any
Raster*
object and accepts all of its parameters. The function adds a
scale, a north arrow and a polygon in the area of interest. If necessary, the
function automatically reprojects the polygon to match the projection of the
raster
. The projection of the map can be changed by modifying the
proj
argument. For futher help on tmap arguements, please go the
tmap
reference manual.
