Thats not my goal!
Is there no plotting function to do this directly?

experinental revision of the 'snow' package
A new version of the 'snow' package for parallel computing in R is
available at
http://www.stat.uiowa.edu/~luke/R/cluster/snow_0.3-3.tar.gz
This substantially revises the way in which worker processes are
started to allow snow to be used on Windows and Mac/Windows/Linux
combinations. I have successfully used the SOCK version on a
standalone Windows machine and combinations of

exit function in R?
Hi,
This is likely an stupid question, but I cannot find the solution.
I am searching for an "exit" function, to end the execution of an R
script if some condition is not filled.
Any clue?
Thank you in advance!

torque/psb & snow library
Hello all;
I'm trying to execute parallel jobs trough library snow on a cluster built
through torque/PSB. I'm succesfully obtaining the cluster with:

>mycluster <- scan(file="cluster.txt",what="character")
>cl <- makeSOCKcluster(mycluster)
The only problem, at the moment, is that if I use

Parallel R for dummies (on hpc)
Hi,
I had access to an hpc cluster, and wanted to parallelize some of my R code. I looked at the snow,nws, rscalapack documentation but was unable to make out how I should submit my job to the hpc, and how I should code a simple program. For example, if I had 10 matrices, and 10 processor how should I write the R (and the hpc submit code) so that I run the calculations (e.g. rowsums) for each

multicore mclapply hangs
When I execute mclapply it creates the needed processes, but these
processes never begin computing anything, they just wait indefinitely.
I recently upgraded to version 2.9.1, which might have caused the problem.

Problem about spawn nodes with Rmpi
Hi all,
now I'm testing R in a "virtual cluster", made it with VirtualBox. This one
has 3 nodes, running CentOS 5 and OpenMPI 1.2.8, and the principal node
(called "server") exports the /home to other nodes.
I have installed R and OpenMPI in /home, in fact, it seems work OK. Editing
the openmpi-default-hostfile and run "mpirun -np 3 hostname" I can see the

cluster/snow question
Dear R Users,
I am attempting to use the snow package for clustering. Is there a way to
identfy, in the environment of each node, a rank for that node and also,
the total size of the cluster ?
By way of analogy, I am looking for the functions in snow equivalent to
mpi.comm.rank() and mpi.comm.size() from RMPI, in case that makes things
clearer.
Thanks in advance,
Tolga

Rmpi and OpenMPI ?
Has anybody tried to use Rmpi with the OpenMPI library instead of LAM/MPI?
LAM appears to be somewhat hardcoded in the Rmpi setup. Before I start to
experiment with changing this, has anybody else tried Rmpi with non-LAM MPI
implementations?

Rmpi task-pull
Hi, I'm testing the efficiency of the Rmpi package regarding parallelization
using a cluster.
I've found and tried the task pull programming method, but even if it is
described as the best method, it seems to cause deadlock, anyone could help
me in using this method?
here is the code I've found and tried:
# Initialize MPI
library("Rmpi")
