multidimensional point.in.polygon??
...id "one general way to do this would be to compute the convex hull
(?chull) of the augmented set of points and test if the point belongs to
it"; an approach I'd considered generalising to multiple points thus (pseudo
R code)...
----------------
baseHull <- convhulln(baseSet)
augHull <- convhulln(augSet)
while (augHull != baseHull)
{ augSet <- augSet [-(augHull !%in% baseHull)]
augHull <- convhulln(augSet)
}
--------------------
... but this has that horrible loop including a convhulln!
In the (real, typical) test data set I'm using for develop...
