[R-sig-Geo] Too many points for deldir()

[Ludwig Hilger]

Hello everybody,

I am trying to construct Thiessenpolygons from a very large dataset (ca. 1.3
mio points) and get the following error:

thiessen <- deldir(normv$X, normv$Y)
[...]
Fehler: lange Vektoren (Argument 7) nicht unterstützt in  .C (~= long
vectors (argument 7) not supported in .C)

I am wondering if this comes from the number of points and if yes, if there
is a way to split the dataset into blocks and putting the result back
together afterwards? I suspect that there will be problems at the
borderlines of blocks!?

Thank you very much and best regards,
Ludwig
