Hi,
Doing some more reading, I think the problem is easier because the hull is
convex. Then an algorithm for testing points might be:
a) Define the convex hull as a set of planes (simplexes).
[as returned by convhulln!!]
b) Define one point, i, known to be interior
[e.g. mean of all
Hi,
Regarding your proposed algorithm (looks like it is indeed the correct
way to do it), there seem to be a somewhat similar Matlab
implementation,

It should be possible to port this to R (you might want to check what
to do with

Hi,
Yet another one of my very naive ideas on the subject: maybe you can
first evaluate the circumscribed and inscribed spheres of the base set
of points (maximum and minimum of their distances to the center of
gravity). Any points within a distance smaller than the infimum is
good, any point
