All, We are researching approaches to parallel R with the end goal of running R in a distributed manner on a Linux cluster. We expect of course to do some work decomposing our problems to be task-parallel or data-parallel, but wouldn't mind getting an initial boost working with "embarrassingly parallel" code sections and one of the approaches below. Incidentally our environment

Hi, I'm trying to understand (mostly from the R-exts manual) how to use the callbacks declared in Rinterface.h. As a first attempt, I'm trying to redefine ptr_R_WriteConsole in a very trivial manner. Here's my code: --------------- $ cat altr.c int Rf_initialize_R(int ac, char **av); #define R_INTERFACE_PTRS 1 #include <Rinterface.h> extern int R_running_as_main_program;

Hi, I think this is a bug (even though I can't find documentation explicitly saying that it should work). Basically, Rf_PrintValue(obj) fails when 'obj' is an S4 object that should be printed using show() rather than print(). From the error message I'm guessing that the need to use show is detected correctly but then show is not found. "cbind2" in the code below is just

Hi, I'm not sure if this question has been answered before, but when I execute command "Rcmd INSTALL --build nws" to build an R package on Windows, the build process got stucked on the save image step. Here is the snapshot of the build process, --- Making package nws ---- adding build stamp to DESCRIPTION installing NAMESPACE file and metadata installing R files

Hi, I am using the caretNWS package to train some supervised regression models (gbm, lasso, random forest and mars). The problem I have encountered started when my training data set increased in the number of predictors and the number of observations. The training data set has 347 numeric columns. The problem I have is when there are more then 2500 observations the 5 sleigh objects start but do

Dear R users, I have a response variable in a csv file called "y" and a matrix of predictor variables in a csv file called "mat". I have used the function "nls" I have specified the nonlinear relation between these variable.The code I have witten is called Rprog which begins with the phrase: L.minor.m1<-nls(Y~a ....etc.. The program when I execute the program, I

hi, I received this e-mail which contains a "ballad", at first I thought it was junk mail, but then I read through it, for the EE members of this list, it may be quite humorous. I don't know if the ballad is original, but at least it's the XMAS season, so it's something to lighten up your day, eh? -samudra """ How the Ground Loop Stole Christmas

Hi, 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: -------------------------------------------------------------------------------------------------------

Hi all, Recently our statistics students noticed that their Gibbs samplers were crashing due to some NaNs in some parameters. The NaNs came from mvrnorm (Ripley & Venables' MASS package multivariate normal sampling function) and with some more investigation it turned out that they were generated by function eigen, the eigenvalue computing function. The problem did not seem to happen

Dear Luke and others, I have many R versions on my machine and want to start a particular one when snow builds its cluster. (The same version I start snow from.) It seems that everything is set up correctly in defaultClusterOptions: > mget(ls(defaultClusterOptions), defaultClusterOptions) $homogeneous [1] TRUE $manual [1] FALSE $master nodename "maya.unil.ch" $outfile [1]

Hello, the package snow is not working on a windows cluster with MPICH2 and Rmpi. There is an error in makeCluster: launch failed: CreateProcess(/usr/bin/env "RPROG="C:\Programme\R\R-2.5.1\bin\R" "OUT=/dev/null" "R_LIBS=" C:/Programme/R/R-2.5.1/library/snow/RMPInode.sh) on 'cl1' failed, error 3 - Das System kann den angegbenen Pfad nicht finden.

When trying to create (a very simple) cluster using makeSOCKcluster or makeCluster I get the following error message: > library(snow) > cl <- makeSOCKcluster("localhost") Fatal error: kann Datei '~/R/i686-suse-linux-gnu-library/2.8/snow/RSOCKnode.R' nicht ?ffnen: Datei oder Verzeichnis nicht gefunden (translation: could not open file [...]: File or directory not

I see about 7 different R packages for multi-process parallel programming. Which do you think is the best, most complete, and most robust to pick for general purpose Erlang-style message-passing programming in R, and why? First here's my use case, and then my analysis so far. I often have code whose basic organization looks something like this: 1. Fetch step: For each date, gather up or

Setting up a new system backup (done several before and they all work fine). Windows 10 x64 (cygwin with rsync version 3.1.2) backing up to ubuntu server 16.04 (rsync 3.1.1). Run test.bat from command window (run as administrator) and it runs fine.Created scheduled task that runs test.bat and it hangs at "msg checking charset: UTF-8" until the timeout. I have upped the timeout to

Hello dear R-help group (and David Smith from REvolution), I would like to perform parallel computing using R with Condor (hopefully using foreach or other recommended solutions, if available) for some "Embarrassingly parallel" problem. I will start by listing what I found so far, and then go on asking for help. So far I found the a manual by Xianhong Xie from Rnews_2005-2 (see page

Hi, I am trying to run the "schools" example in the rbugs library (running winbugs in linux via wine-20041201) but keep getting the following error. Note I have tested wine and winbugs to confirm that both are operational. Error in runBugs(bugs, script.file, n.chains, workingDir, useWine, wine, : BUGS stopped before getting to coda. The command I'm using is:

Hi all I am trying to backup via ssh the complete contents of a hard drive, but I'm running into some trouble. The source is an ext3 drive on an Ubuntu 9.10, and contains various files with sizes ranging from several KB to 5GB to a total of approximately 250GB. The source is a modified LaCie NetworkSpace 500GB on which I've opened a new root user and installed tools such as ssh and

Hello, I'm having trouble calling rsync from java on windows vista with cygwin installed. Its strange as pasting the exact same command into a command shell works fine. My test java call looks like this. * String[] envVars = {"PATH=c:/cygwin/bin;%PATH%"}; File workingDir = new File("c:/cygwin/bin/"); Process p = Runtime.getRuntime().exec("c:/cygwin/bin/rsync.exe
