lam vs. openmpi
Dear R Debian Users:
I wrote a quick C program (eventually to become R code) and compiled it as:
mpicc -o greet greet.c
So far so good. Now when I run mpirun, this happens:

It seems that there is no lamd running on the host erin-laptop.
This indicates that the LAM/MPI

trouble with snow and Rmpi
Dear R People:
I am having some trouble with the snow package.
It requires MPICH2 and Rmpi.
Rmpi is fine. However, I downloaded the MPICH2 package, and installed.
There is no mpicc, mpirun, etc.
Does anyone have any suggestions, please?
Thanks in advance!

I am working on a 64-bit rocks cluster and am relatively new to the
R package. I am trying to get Snow working with R and Rmpi and have
run into the following issue. R is able to load the Rmpi and snow
libraries and is able to run simple commands both interactively and
batch as follows:

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

Rmpi and PBS
Hello:
Anybody knows how to run Rmpi through PBS (Portable Batch System) on a
cluster computer. I'm using a supercomputer which require to submit jobs
to PBS queue for dispatching. I tried use mpirun in my PBS script. But all
my Rslaves are spawned to the same node. This is not desired.
Any suggestions are welcome!
Thanks in advance.

problem with Rmpi 0.5-5 and openmpi
Dear knowledgeable experts :-),
I am trying to get openmpi, Rmpi and SNOW running on a Myrinet/GM
cluster. I'm not an IT expert, but I surely could use a working
installation of Rmpi and SNOW.
I try to load the Rmpi library and get the following:

R and Openmpi
Hello,
We have R working with Rmpi/openmpi, but I'm a little worried. Specifically, (a) the -np flag doesn't seem to override the hostfile (it works fine with fortran hello world) and (b) I appear to have twice as many processes running as I think I should.

omitting columns from a data frame
Dear R People:
I have a data frame, xm1, which has 12 rows and 4 columns.
If I put is xm1[,-4], I get all rows, and columns 1 - 3, which is as
it should be.
Now, is there a way to use the names of the columns to omit them, please?
Thanks so much in advance!
Sincerely,

Problem with compiling OpenBLAS to work with R
I believe that repo just follows the directions on my blog. Without seeing
Dr. Hodges?s code, my initial concern is the many references to Cygwin. My
method specifically does not use Cygwin but MSYS2 and Mingw64/Rtools35.
That will likely change to solely Rtools40 once R3.6 is released due to the
Msys system being built in to it.
There may be some library conflicts between Cygwin and

Strange behaviour of ssh
Hello together!
I've Debian 6.0.3 with OpenSSH_5.5p1 and problem with the execution of remote commands via ssh.
It seems as if the first command isn't looked up in all "$PATH" dirs.
Here normally I should get the version information of mpirun twice but the first one fails:
$ ssh cluster2 mpirun --version ; mpirun --version
bash: mpirun: command not found

replicating C example from the Extensions Manual problem
Dear R People:
Here is something that I am sure is very simple. I'm just trying to
re-create the C convolution example in the Extensions manual. Here is
the subroutine:
void convolve(double *a, int *na, double *b, int *nb, double *ab)
{
R_len_t i, j, nab = *na + *nb - 1;
for(i = 0; i < nab; i++)
ab[i] = 0.0;
for(i = 0; i < *na; i++)

ab[i + j] += a[i] *

attr question
Dear R People:
When I want to produce a small sample confidence interval using
t.test, I get the following:
> t.test(buzz$var1, conf.level=.98)$conf.int
[1] 2.239337 4.260663
attr(,"conf.level")
[1] 0.98
How do I keep the attr statement from printing, please? I'm sure it's
something really simple.
Thanks,
Sincerely,
