hello, I'm using R 1.8.1 with the lastest snow package on FreeBSD 4.9. However, when I try to using socket clusters, it's very unstable. Sometimes it dies half way when I run parSapply(), sometimes it dies when cluster connection is idle. I create a socket cluster by following cmd cl = makeCluster("foo", type = "SOCK", outfile="/tmp/rafanlog");

Hi there, We're attempting to run an LVQ analysis over a cluster of machines via R and openMosix. R spawns several child processes simply by writing commands to several files and using system() to start a slave process. The processes migrate perfectly, and often finish with no reported errors, writing their results into respective files for the parent process to piece together.

Rmpi is not currently available on CRAN, and I don't think it has been for a few months. It is available at http://www.stats.uwo.ca/faculty/yu/Rmpi/ Does anyone know its current status? A few months ago I corresponded with the author, who noted some build problems (specifically on Debian) were the hang up, and seemed to be working on it. I wasn't able to get it to work then (on a

Dear R-devel, Inspired by Michael Li's talk at JSM, I decided to try rpvm and snow on our two linux boxes. It only took me a couple of hours of screwing around to get it working (sooner if I had RTFM). Our setup is: 2 dual PIII-866 Xeons, one with 2GB RDRAM, the other with 1.28GB RDRAM. The first machine is acting as the NIS/NFS server. both /usr and /home are exported to the second

Dear R People: Is there a binary version for rorca, please? Thanks, Laura mailto: lauraholt_983 at hotmail.com R Windows 1.9.0

Hi, does anybody know how to use the dual processors in the machines of a cluster? I am using R with rpvm and snow packages. I usually start pvm daemon and add host machines first, and then run R to start my computing work. But I find that only one processor in each machine is used in this way and the other one always stays idle. Is there any simple way to tell pvm to use the two processors at

Almost all of the heavy crunching I do in R is like: > for(i in long.list){ + do.something(i) + } > collect.results() Since all the invocations of do.something are independent of one another, there is no reason that I can't run them in parallel. Since my machine has four processors, a natural way to do this is to divide up long.list into 4 pieces and then start 4 jobs, each of which

I tried ot build rpvm in my own makefile. But runs into some linker errors like e.g. undefined reference to `_R_alloc' My enviornment looks like this: CYGWIN pvm 3.4 compiled under cygwin myself R installed from the rw2001.exe setup file. I guess that the R under rw2001.exe was build with some other compiler? I then tried to compile R myself under CYGWIN but runs into the following

I'm trying to track down a rather critical problem. This happens both on Debian's current unstable as well a from anoncvs built this morning, reinstalling MASS. Is anyone else seeing this or am I just broken and special? 609$ /home/Rdevel/bin/R R : Copyright 2004, The R Foundation for Statistical Computing Version 1.9.0 Under development (unstable) (2004-03-04), ISBN 3-900051-00-3 R

Dear all, does anyone know if there exists an effort to bring some kind of distributed computing to R? The most simple functionality I'm after is to be able to explicitly perform a task on a computing server. Sorry if this is a non-informed newbie question...

In a quick search of the R website just now, I found no mention of a unit testing framework for R. I hope to find something in the style of Java's JUnit, or Python's unittest. Is such a thing available? Thanks, - Paul Shannon Institute for Systems Biology Seattle

Dear People, This may not be the right place to ask a question about Rmpi, but I don't know of a better one. I am trying to get a simple program working using Rmpi with the model of 1 R master and n C slaves. What I am trying to do is have each of the C slaves generate a random number from U[0,1], and then have the master collect all n numbers as a vector and output it. However even doing

I've been using a cvs2cl.pl (http://www.red-bean.com/cvs2cl), a nice little perl script to auto-generate GNU-style changelogs from CVS log information. This site also has a proposed XML format for changelogs, and cvs2cl can optionally produce this instead. Finally, they have an XSLT sylesheet that will convert the XML changlong format into an HTML/XHTML page. How about we borrow this tool

Yes, lots of packages do use C/Fortran code ... it would be great if there were more packages that are "pure R" especially since the advent of S4 classes and namespaces. Is it worth suggesting that we create a designation "pure R" for packages that have no external source code and encourage more of these? Indeed, now the number of packages is so big could they be classified to

Thanks to Luke Tierney, Agustin Lobo, Stephen Eglen, A.J. Rossini, Simon Wood and Timothy H. Keitt for responding to my question about poor man's parallel processing. Much of the substantive material was cc'ed to r-help already, but my take is as follows. 1) Currently, there is nothing "simple" for solving my problem. 2) I thought that Timothy Keitt's description of the use

Hi folks, is it possible to read more things about R behavior in multiprocessor / multihost environment ? Is there any distributed computation project associated to it ? Laurent

Hi to all who suffer from rterm not shutting down in xemacs/ESS on windows NT or 2000. Also hi to those who could eventually help. Here is some more information which could help and some ENCOURAGEMENT to contribute to a solution. 1. It may be an xemacs problem but it is more likely an interaction between rterm/comint/and xemacs. In fact, the problem started occurring around version R 1.6.0. I

Evening folks: I did an install.views of finance and econometrics and between the two of them R reported 'FracSim', 'RDCOMClient', 'snow', 'VGAM', and 'segmented' as missing dependencies. Now, I've managed to hunt down what appear to be current zip file copies of all of the packages but 'snow'. Is there a windows edition of the package out

I'm seeing weird issues in methods initialization, i.e. loading marrayClasses loads Biobase, and when explicitly done, as in library(Biobase) library(marrayClasses) is fine, but when Biobase is loaded via a require statement in marrayClasses' .First.Lib, I end up with: Warning message: In the method signature for function "coerce", class "exprSet" has no
