Accessing R as a Web service (UNCLASSIFIED)
Classification: UNCLASSIFIED
Caveats: NONE
I am new to R and somewhat to Web server programming.
I am a Java programmer, however, and have done quite a bit with X3D
(extensible 3D) computer graphics.
A statistician that I work with is doing multidimensional scaling (MDS) and
provides some x,y,z's which I display using X3D.
Currently he is using Permap which more than gets the job done

hardware accelerated 3D-graphics in Win-XP-domU possible?
Is there any way to make gaming in domU work? It''s not clear to me, if
this can be done with open-gl or so.
If this is impossible now, is some development planned in this area?
Eventually I would wait buying my next pc until the necessary cpu features
are available.
TIA, martin

Installing xaudio2 (Serious Sam Second Encounter HD)
Is there a way to install xaudio2 without using the large `winetricks directx9' ?
I am asking because I would like to try serious sam second hd, but in a clean wineprefix it does not start asking for a xaudio2 dll.
I copied that .dll inside the game directory, but the game starts soundless and it shows an error about an non-updated xaudio2.
A part of the lack of the audio the game runs

Package ``deldir'' available from CRAN.
A package for calculating and plotting the Delaunay triangulation and
the Dirichlet/Voronoi tessellation, of a planar set of points, is now
available from CRAN. The package is called ``deldir''.
The package consists of a port from Splus to R of a library section
which has been available for some time from the Splus software
segment of statlib. (The Splus library section is called

Deldir() Thiessen Polygons Problem
Good evening to all.
I find myself trying to create some Thiessen Polygons, in order to finish a
meteorology research.
This is the script I found to create the Polygons:
*
*
*voronoipolygons <- function(x) {*
* require(deldir)*
* if (.hasSlot(x, 'coords')) {*
* crds <- x@coords *
* } else crds <- x*
* z <- deldir(crds[,1], crds[,2])*
* w <- tile.list(z)*
* polys

Geometry delaunayn and deldir results, differing results from Octave due to decimal precision?
I just looked at the data at the URL you posted and it looks like it
consists
of all the points in a rectangular grid. When you triangulate a rectangle
it is
arbitrary whether you use the SW-NE or the SE-NW diagonal and that looks
like the only difference between the various algorithms.

rounding of voronoi vertices using deldir()
Hello list,
I'm just getting started with using R - I have been trying over the past
day or so to work out a method for generating voronoi polygons for
PostGIS using SQL. I was able to put together a procedure which works
relatively well, but is somewhat inefficient. Someone on the PostGIS
list pointed me to the deldir() function in R, for which I can export a
text file with x/y coordinates

Geometry delaunayn and deldir results, differing results from Octave due to decimal precision?
"The question is, what is making the results for the R packages different
from each other?"
There are literally thousands of R packages, contributed independently by
thousands of people. There should be no expectation of consistency or for
that matter, "correctness", among them. Caveat emptor.
Only within the base R distribution, maintained and mostly written by the R

Geometry delaunayn and deldir results, differing results from Octave due to decimal precision?
The problem:
I would like to translate the Octave algorithm in griddata.m to R.
Within the griddata algorithm calls are made to the Delaunay function. For the R translation I have found delaunayn within the "geometry" package and also the deldir package.
Both do similar things but give slightly different results depending on the input.
The question is, what is making the results for the

Loading Data to R
This is the most basic question ever...I haven't used R in a couple years
since college so I forget and haven't been able to find what I'm looking for
in any of the manuals.
I just need to figure out how to load a dataset into the program from excel!
Thanks!

pdbedit and tdbsam
I'm having trouble using pdbedit to add user to a
tdbsam database. I'm running Redhat Enterprise Linux
ES 3.0, with the stock version of samba. I'm not sure
why it won't let me add users. I tried it with
smbpasswd and that didn't work either. Anyway here's
a plethora of information:

However I have changed the first two patches based on feedback

selecting predictors for model from dataframe
Dear all,
I think I have a rather strange question, but I'd like to give it a try:
I want to perform a simulation numerous times, thats why I can't do it by
hand. I sample a small dataset from a very large one, and use backward
selection to select significant predictors for some arbitrary outcome
variable Y. These predictors are to be placed in a model, and regression

John Rosatti, Excavators, 3D, NASA and Why Should I care?
Well, because! There are two definitions for excavator; one is any person
engaging in excavation is called an excavator. The second definition of
excavator is, of course, the vehicles called excavators, which are sometimes
called diggers, trackhoes, fronthoes, and 360-degree excavators or just
360. This is not to be confused with
