approx_areas

shape object, i.e. a SpatialPolygons(DataFrame)

total area size of <code>shp</code> in number of squared kilometers. If <code>NA</code>, and <code>unit="km2"</code>, then the polygon coordinates are assumed to be in meters.

total.area.km2

one of
[object Object],[object Object],[object Object],[object Object]
    The default method is <code>"abs"</code>, unless <code>total.area.km2</code> is specified (in that case, it is <code>"km2"</code>).

units

This function approximates the area sizes of the polygons either in 1) squared kilometers, 2) absolute numbers based on the polygon coordinates, 3) proportional numbers, 4) normalized numbers.

Thematic maps are geographical maps in which spatial data
    distributions are visualized. This package offers a flexible, layer-based,
    way to create all kinds of thematic maps, such as choropleths and bubble
    maps.

approx_areas: Approximate area sizes of the shapes.
