Dear All,
please, does anyone know if there's an R script or package to compute
the exact % of overlap of convex hulls in 2D scatterplots?
I found something but was developed for high dimensional spaces and
seems to compute that using an approximation. In 2D it should not be
too difficult to get
Andrea,
There are two ways to do this, one precise and one less precise. The less
precise method is to calculate the convex hull areas of three hulls: the two of
interest and one comprising the points of both. Subtract the total area of the
comprehensive hull from the sum of the two groups
