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

It will be easier for folks to help you if you provide example code that
produces a plot like the one you are dealing with.

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

clearly anymore and want to ask for some outside comments, to maybe

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,
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, 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

this might be the case.)
Try doing something like:
newbm - bm[!duplicated(bm),]
and then hit newbm with both deldir() and delaunayn().

Thanks for the answer!
I'll post a sample tomorrow, I have however found the following:
triang.list() gives me the coordinates of the triangle's vertices,
while delaunayn() gives me the indices of those coordinates. Thus it
should
:
install.packages(deldir)
library(deldir)
?deldir
set.seed(16180)
x - runif(20); y - runif(20); window - c(0,1,0,1)
tess - deldir(x, y, rw = window)
plot.deldir(tess, wpoints=real, wlines=tess)

How about you post a small input dataset and list the output that you

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
