Hello [R]ians, I'm hoping someone can clarify the difference between a Workspace Image and Working Directory. I created a directory on my PC, say, "C:\Program Files\R\Project1" and then saved my objects in "C:\Program Files\R\Project1\.Rdata". Then, in a subsequent session, I reloaded these objects using > load("C:/Program Files/R/Project1/.RData") At

I have a large dataset (questionnaire results) of mostly categorical variables. I have tested for dependency between the variables using chi-square test. There are an incomprehensible number of dependencies. I used the chaid() function in the CHAID package to detect interactions and separate out (what I hope to be) the underlying structure of these dependencies for each variable. What typically

Hello R-ians, Could someone please point me to documentation on legal font and color specifications (and other 'par' parameters); i.e. font=6 for Times New Roman, col='Red', etc.? Searches in "?par", MASS (1st ed.) and other areas were unsuccessful. I thought I remember seeing it before...somewhere. Thanks, Iyue

Dear R List, I'm interested in modifying a regression tree algorithm to use the difference between a control and a dosed sample as its dependent variable. I was wondering if anyone knew where I could find

Dear Colleagues, I've been looking for a function that can perform a tree analysis, similar to CHAID or QUEST. The key point is that in this case the variables are not binary but nominal (10 different values), so "tree" (from the tree package) won't work. Does anybody know help?

I am looking at options for VPN connections from iPhones and iPod Touches to CentOS systems. We use OpenVPN for connections with Windows, Mac OS X, and other Linux systems, but there don't appear to be any OpenVPN clients for iPhones (presumably because there are no tun/tap interfaces available yet). My experiences getting IPsec running on CentOS systems with OpenVPN have not been pretty.

Hi., I would like to conduct a CHAID tree analysis - Chi-square Automatic Interaction Detector. >From what I can make out from MASS, tree, rpart, and a quick search it isn't available as a package. Is that correct or have I missed it? Has anyone an available implementation of it? Thanks Stephen Nana Mail <http://mail.nana.co.il> - Get Your Free Personal Outlook 2003 Now

Hi! I'm using Roundcube 0.9git as mail frontend and have installed Dovecot 2.1.7 on Debian Squeeze. When searching for mail via Roundcube and the keyword contains "special" chars (like german umlauts), then Dovecot seems to die when the folder does not contain a message which contains this keyword, i.e. folder contains message /w subject "Dies ist eine Nachricht" =>
