Dear List Forgive me for the slightly off topic query Force.com and Salesforce have many (1009) apps at http://sites.force.com/appexchange/home for cloud computing for businesses, but very few forecasting and statistical simulation apps.

Hi, who of you in this forum uses R (http://www.r-project.org/) with the multicore, SNOW or CUDA packages, so for advanced calculations that need more power than a workstation CPU? On which hardware do you compute these scripts? At home/ at work or do you have data center access somewhere? The background of these questions is the following: I am currently writing my M.Sc. thesis about R and

The Rserve documentation at http://rosuda.org/Rserve/doc.shtml#start states that even when making multiple connections to the Rserve, Windows won't separate workspaces physically and share environments, which will obviously cause problems and should therefore not be used. Are there any alternatives for the windows platform? Ralf

First it got RCmdr and Car, and then suggested for other packages for utilizing the full functionality- I clicked yes! I got 140 packages installed!!! Cran Mirror was UCLA... Here is the list. Is this intentional- I can see some packages like snow and multicore which are desirable but quite optional.(see list

Dear Group, I'm having lots of problems getting RMySQL on a 64 bit machine. I followed all instructions available but couldn't get it working yet! Please help. See the output below.

I am running R on Ubuntu Heron. I recently updated to R 2.8.0 from the default (2.6) in the Ubuntu heron repository by adding deb http://cran.stat.sfu.ca/bin/linux/ubuntu hardy/ I updated all packages installed in /usr/lib/R/site-library and those in my home directory /home/duncan/R/i486-pc-linux-gnu-library/2.6 without obvious issues. I installed adehabitat and gpclib, which should be good

Hello Everyone,   Just finished reading A Handbook of Statistical Analyses using R by Everitt and Hothorn. I'll begin by saying that I quite liked the book. It's both little and mighty in the sense that it's very compact but contains a tremendous amount of useful material.   The last chapter of the book deals with cluster analysis.  There's a package used in this chapter (I believe

Folks, I'm making progress moving from Windows to Linux and have RKward up and running. I read somewhere that Rkward's supposed to be the Tinn-R for linux and Tinn-R has worked out great for me. So naturally I'd like to do the following, if possible, 1. How to ask Rkward not to load the last saved image. Right now whenever it starts, it loads an image from some obscure corner of my

Hi I tried to install rkward under ubuntu hardy heron, but it tried to use the one from the cran repository which was newer, but it did not install. To be able to install rkward, I had to disable the cran repository, install rkward, lock it's version and enable the repository again. I have the feeling, that the dependencies are not correct (it is looking for libqt4GUI, but I have a

Hi, I'm testing rkward to use in my class. Now I'm using XEmacs, but for many people XEmacs is more complicated than R. Anybody here use this program? It use plugins, what are these plugins?
