Hello everybody!
I feel very stupid right now but suspect it has something to do with
tiredness. I am trying to drop the last couple of Elements from a list
and this doesn't work as expected.
My code looks something like this:
del <- deldir(x, y)
tl <- tile.list(del)
plot(tl)
Now, I only want to

Hello,
I have a somewhat complicated question and hope, someone can help me
or that there is a solution at all for my problem.
I am using R to plot the results of a Voronoi-Tesselation. I am
however only interested in a small part of the plot, around the
center. Is there a way to cut out the centra

Hello again,
After playing around with my current problem for some time, I have
once again returned to Delaunay Graphs and after banging my head
against the problem for some time I fear that I can't see the issue
clearly anymore and want to ask for some outside comments, to maybe
shake my thoughts
works and should (or
should not) be used, but I'm always willing to understand more about
the code I'm working with.
Thanks again!

Hello everyone!
In my ongoing odyssey through badly dokumented and sparingly commented
R-code, I've come across something that baffles me.
The following line of code
.Internal(filledcontour(as.double(x), as.double(y), z,
as.double(levels), col = col))
not surprisingly results in an error, telling

Hello everyone, I have a question which is probably rooted in my lack
of understanding when it comes to math.
I just did the following:
v <- c(1:20)
w <- c(11:30)
setdiff(v, w)
and got:
1 2 3 4 5 6 7 8 9 10
Then I did the following:
setdiff(w, v)
and got, not surprisingly:
21 22 23 24 25 26 27

lie somewhere else?
Once again please excuse my slightly chaotic description of my
problems and my faulty english and thanks for any help you can give!

Hello everyone!
I have returned to R after a longish break and am currently working on
a project where I need Delaunay-Triangulations and Voronoi-Diagrams.
If I understood it correctly, the Geometry-Package only offers
functions for the Delaunay-Triangulation at the moment. Is this
correct and if s
