I have the same suspicion, unfortunately I am no Matlab-User either
and only have a adjacency-matrix created by the corresponding matlab
functions to compare with my own output. So, even though I don't see
any use for collinear triples either, is there a way to get them with
deldir as well?
Uh, no. Fortune fortune(228) springs to mind here.
cheers,

You are almost surely being bitten by the issue about which you
previously made inquiries to me, concerning the delaunayn() function
from the "geometry" package. (NOTE: ***PACKAGE***!!! Not "library". A
library is a *collection* of packages.) The delaunayn()
function also uses the qhull algorithm. By default it treats some
triples of *collinear* points as triangles. This is probably causing
the discrepancy between the results.
Ergo it would seem best to use deldir() unless you *really want*
collinear triples to be considered as triangles --- and I can't see why
you would.
