[R] calculate area between intersecting polygons

[Remko Duursma]

Dear Jonas,

if you can write the difference in y-values between your polygons as a
function, you can use
integrate() to get the area between the polygons.

It sounds like perhaps your x-values will not match between the polygons
because they come from different sources, so you probably have to do some
interpolating (with ?approx).


hope that helps,
Remko
