similar to: CHAID in R

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

Quick disclaimer: I'm new to the list and I'm not sure if I'm sending this to the correct forum. If there is a better place for questions like these, please let me know! 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

I am importing a dataset in R where some of the variable are numerical and some of them are character...but the problem is that R is treating numerical variables as character (I am using "is.character" to judge the type). Now the question is how can I convert these character variables into numeric and also let me know about the other conversion like "numeric to

Can I say that RPART is a modified algo of CART and PARTY a modified of CHAID?

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?

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

Dear Samba members, I am wondering if on joining a realm (with security=ADS), samba 3.x server gets automatically registered with MS Dynamic DNS server. My test with Samba 3.0.14a on linux did not reveal any such capability. But may be because I did not use the correct option? I would appreciate any help. Thanks in advance, -Arup Biswas
