Dear All I am doing one distributed data mining program. So I selected GridR package for the distributed programming. *grid.init(service="local",debug=FALSE, localTmpDir="GridRTmp/") grid.apply("x",UCS, wait=TRUE )* UCS is a function. When I execute this statement, I have some errors like : *cannot load local function/variable: xmlRoot extracted from line: : no

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 use 'GridR' package for the first time, and I'm running into a strange error from grid.check: > grid.check(gridFun) Error in exists(add) : invalid first argument After playing around in recover mode, I see that this because the variable 'add' created by grid.check is blank: Browse[1]> split[[1]][k] [1] " : " Browse[1]> add [1]

Dear all I am implement one grid computing system using GridR package. I am working on windows platform. I did all the configuration according to the GridR tutorial. But it has some errors when I execute grid.apply function. Here is the output from stderr: R: not found java.io.IOException: Error during SCP transfer. at com.trilead.ssh2.SCPClient.get(SCPClient.java:703) at

Hi everyone,   I'm trying to do an Logistic Politomic Regression in R. Because I have my resposes variables and the aswer is 0 and 1 in 3 bacterial genes.

Is there a way to estimate a nominal response model? To be more specific let's say I want to calibrate: \pi_{v}(\theta_j)=\frac{e^{\xi_{v}+\lambda_{v}\theta_j}}{\sum_{h=1}^m e^{\xi_{h}+\lambda_{h}\theta_j}} Where $\theta_j$ is a the dependent variable and I need to estimate $\xi_{h}$ and $\lambda_{h}$ for $h \in {1...,m}$.
