An all-R routine that computes area of all
polygons in a
taking account of holes.
A spatial object inheriting from
Provides the same answer as
rgeos::gArea, but is
all-R (does not require rgeos Java library) and does not
fire a warning if
x is un-projected (i.e., lat-long).
Area of all polygons in
x, taking account of holes.
Units of area are squared units of coordinates in
square meters if coordinates in
x are UTM meters, square
decimal degrees if coordinates in
x are lat-long decimal
