Dear all the regular XML package does not work correctly with the R 2.0.1 windows version. Can anybody indicate a suitable alternative ?

I have a comma delimited text file in which many columns of numbers are also quoted and have commas as well as decimals. I was surprised to find read.csv() didn't import this seamlessly, even after messing around with the colClasses argument. I did find a solution to convert the character strings after reading them in, but wonder if there isn't a better one I overlooked. test =

Hi all, I'm having a strange error that prevents me from installing new packages, or updating packages after reinstalling. The error message is Warning: unable to move temporary installation ‘C:\Program Files\R\R-2.14.2\library\file15045004ac2\sandwich’ to ‘C:\Program Files\R\R-2.14.2\library\sandwich’ for one of the packages that is failing to install/update. This error started happening

Hello, I used the glm function in R to fit a dose-response relationship and then have been using dose.p to calculate the LC50, however I would like to calculate the NOEL (no observed effect level), ie the lowest dose above which responses start occurring. Does anyone know how to do this? [[alternative HTML version deleted]]

Hello, I would be extremely grateful if anyone is able to provide any (rather obscure) advice on using R with Condor. I think I'm following Xianhong Xie's instructions (R News 5(2) 13-15) correctly, but my job just stays held in the queue (for days / months). I've checked condor_status to make sure there are plenty of machines available, but can't see any way to attack the

Hi Everyone, I have group of R jobs that should be submitted to the condor when I submit the jobs to the condor, they don't run and when I checked the Sched Log files the jobs are exiting with status code 10. Previously, the jobs ran well on condor but now when I submit the jobs on condor they aren't running.Can anyone explain the meaning of this? Here is my submit file: # Submit file

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 was wondering if anyone has successfully linked R against the Condor libraries so that R can be run as a Condor job in the "standard" (not "vanilla") universe. The advantage of this would be that due to checkpointing, jobs can be suspended and transferred to another node. There is a good overview by Xianhong Xie here:

Dear Experts, Could someone recommend some "quick and dirty" HOWTO on condor based cluster? A did a bunch of cluster setups, I always used PBS (or torque lately). But my professor wants his to be Condor. I started reading Condor documentation, and it is vast. And quick route, like: architecture chart, and parameters I need to configure on master/submit, and compute nodes - somehow

Hey all, I need some help with a cross validation. I'm new with R and as well with statistics. I had a group work to create a tool for remote sensing class that extracts the best bands of hyperspectral satellite images that describe vegetation. Its a regression between a linear function of using a normalized differenced index (i-j)/(i+j) while i and j are the bands (in the data these are the

Sorry, spoke too quickly! The problem was caused by my editing the MkRules file with an editor that replaces tabs with spaces. Make evidently requires that all lines start with a tab (see http://www.delorie.com/djgpp/v2faq/faq22_17.html). Perhaps worth warning windoze users like myself of such perils in readme.packages or somewhere similar! Now I have a new problem, but it looks fixable.

Dear list, I am trying to reclaim what I think is lost memory in R, I have been using gc(), rm() and also using Rprof to figure out where all the memory is going but I might be missing something. I have the following situation basic loop which calls memoryHogFunction: for i in (1:N) { dataset <- generateDataset(i) fit <- try( memoryHogFunction(dataset, otherParameters)) } and

Hello: While running R doing the analysis of my data I (using packages such as BIOMOD or e1071) get the following error as a result of several of my analysis: Error: cannot allocate vector of size 998.5 Mb In addition: Warning messages: 1: In array(c(rep.int(c(1, numeric(n)), n - 1L), 1), d, dn) : Reached total allocation of 4095Mb: see help(memory.size) 2: In array(c(rep.int(c(1,

Problem number one: ------------------- I'm running a few-hours-old CVS version of Samba 3.0 with LDAP as the authentication backend, and I'm having some problems trying to set up the LDAP accounts using "smbpasswd". I build the structure of the LDAP database by importing a couple of LDIF's, and then I import the following user account to create an administrative account

I need to serialize computing job requests for two different multicore machines, and in some near future, for a cluster. I have worked with SGE but it requires NFS and other administrative steps, plus it seems a bit overkill for my needs. I guess some simpler queue managing engine may have been developed, possibly over SSH. Any pointers? TIA. -- Eduardo Grosclaude Universidad Nacional del
