Extracting correlation in a nlme model
Hi R users:
Is there a function to obtain the correlation within groups
from this very simple lme model?

exact goodness-of-fit test
Hello,
I have a question concerning the R-function chisq.test.
For example, I have some count data which can be categorized as follows
class1: 15 observations
class2: 0 observations
class3: 3 observations
class4: 4 observations
I would like to test the hypothesis whether the population probabilities are all equal (=> Test for discrete uniform distribution)

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

Rmpi and C Code, where to get the communicator
Hello,
I try to write parts of my code in C to accelerate the for-loops. But
basic operations I want to do in R (e.g. start cluster). My R code looks
something like this:
library(Rmpi)
mpi.spawn.Rslaves()
mpi.remote.exec(....)
dyn.load("test.so")
erg <- .Call("test", ....)
....
mpi.close.Rslaves()
mpi.quit()
And my C function looks something like this:

simultaneous computing
Hello,
which possibilities are available in R for simultaneous or parallel
computing?
I only could find biopara
(http://cran.r-project.org/src/contrib/Descriptions/biopara.html)
Are there other possibilities?
Are there special groups working on simultaneous computing with R?
Thanks

ParallelR
Anyone using or has access to ParallelR? I was looking at the page and
found nothing really useful!

batch systems like Grid Engine or Xgrid:

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.

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

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:

The only problem, at the moment, is that if I use

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?

Problem with C extension
Hello,
I try to write an extension in C, to get a faster functions.
Therefore I have to add an element (vector) to a vector. The command in
R is very simple: x = c(x,a)
But in C I have the problem to reallocate my vector for getting more
space. Everything I tried, I get a "Segmentation fault".
So, how can I combine two vectors in C and give the result back to R
(return(x))?
Thanks

Namespace and function open
Hello,
I built a package, everything was working very well. Now I included a
NAMESPACE to export only some variables. (export(f, g, ...) )
Everything is working fine, except one function. There I get an error:
Fehler in UseMethod("open") : keine anwendbare Methode f?r "open"
In this function I use the function "open" to generate an output bar.
