Thank you very much, this looks promising.
I have a follow-up question however, probably due to my thickness when
it comes to the underlying math.
I am translating (as closely as possible) some code that has
originally been written for Mathlab and uses the delaunay() function
there. Now, if I understand it correctly, Mathlab uses the same
Qhull-Library as a basis, as does the Geometry-Package. So in theory
delaunay(x) in Mathlab and delaunay(x) in R should give me the same
results for the same x, where x is a matrix of coordinates.
If I use deldir(x1, x2) where x1 and x2 are the first and second
column of that same matrix above, is there any chance to get the same
result as with delaunayn() or at least something similar in format to
the result of delaunayn()?
Many thanks again and please excuse my crude english.
