BIC vz SBIC vz SIC
DeaRs, I have a doubt about: BIC (Bayesian Information Criterion) SBIC (Schwartz Bayesian Informarion Criterion) SIC (Schwartz Information Criterion) In many references these are know as the same (eg. stepAIC() function) but I just found a SAS8.2 output that show either the BIC and SIC values for a logistic regression.. simillary values but different. 1) question: What are the differences?

data mining/text mining?
Dear R-user, Could anybody tell me of the key difference between data mining and text mining? Please make a list for packages about data/text mining. And give me an example of text mining with R (any relating materials will be highly appreciated), because a vignette written by Ingo Feinerer seems too concise for me. Thanks _____________________________________________ Dr.Ruixin ZHU Shanghai

party - ctree() - terminal nodes reference for every obs
Dear R.Users, using ctree() (from "party" library) on a data.frame, I want to append a column with the references for the groups/segments detected. While these nodes are easy readable in output, I need a vector for my obs. Hints? Cheers -- Daniele Medri

Group a dinamic number of vectors in a data.frame
Hi all, I need to create a data.frame from a variable number of vectors. The number of these vectors could change so I need a dinamic way to group all in a data.frame. The number is length(abc). e.g. vectors in my workspace N1 <-c(1,2,3,4) N2 <-c(1,2,3,4) N3 <-c(1,2,3,4) abc <-c(1,2,3) the data.frame I want to create: tcm <-data.frame(OneVector, TwoVector,

data mining: finding association rules
Dear R-users! I would like to search for "association rules" (and compute support and confidence, for example) in a data set, and wonder if this can be done with R (version 1.5.0 for Windows)? Particulary, I wonder if a) anyone has done something like that with R or b)maybe someone has written an R-interface to some existing algorithm/software (e.g. to something like the

R Weka and cobweb
Hi, I never use cobweb before and I'm quite new to this. I have a couple of questions around the cobweb implementation in R Weka. If you could supply answer or insight, I would really appreciate. 1. From Fisher's paper in 1987, it seems that Cobweb only deals with nominal data. In R Weka cobweb, is it allowed to accommodate real/continuous value? 2. My understanding is that Cobweb

Hints for Data Mining
Dear All, I am recycling a previous email of mine where I asked some questions about clustering mixed numerical/categorical data. This time I am more into data mining. I am given a set of known statistical indexes {s_i}, i=1,2...N for a N countries. These indexes in general are a both numerical and categorical variables. For each country, I also have a property x_i whose value is known, but

DNS and DHCP setup
Hi, Does anyone know of a document that gives details on how to set up Bind 9 and DHCPD 3.x so that dns is updated when clients log on? I saw this is not in the howto collection (http://www.bibsyst.no/samba/docs/man/DNSDHCP.html#id2981727) so I was kind of hoping someone else has some notes. I would be greatfull for any tips and links. Tarjei

Data mining
Hola, ¿cómo están? Soy estudiante de Ing. en Sistemas de Información y estoy cursando la materia Tecnologías para la Explotación de Datos. Me he decidido a usar R para hacer DM. Estoy recién comenzando con ambos. El asunto es que no he encontrado la implementación en R de uno de los algoritmos que dimos para árboles de decisión, ID3. Ya revisé varios de los paquetes para DM

R or weka
Hi, guys: These days I keep using R and Weka to do data mining. I think my next step is open the source codes so that I can "customrize them" and make them better server my purpose. But now I kinda hesitate to do so b/c I am really not sure which is better to start with. You know, both require some time and I cannot clone myself to work on both:) If here are some persons who used both

Decision Trees
I am familiar with the rpart and tree packages for classification and regression trees. However, quite a bit of the research in the transportation community relating to decision trees uses the C4.5 family of algorithms by Quinlan. Are there any plans to make a C4.5 (or a derivative of it) available to R? If not, then I might use the WEKA Java package ( http://www.cs.waikato.ac.nz/ml/weka) that

Regular Expressions
Hi, Is there a way to use regular expressions to capture two or more words in a sentence? For example, I wish to to find all the lines that have the words "thomas", "perl", and "program", such as "thomas uses a program called perl", or "perl is a program that thomas uses", etc. I'm sure this is a very easy task, I would greatly appreciate

Newbie with R
Hello, I would like to test some learning algorithms (C5.0, or C4.5) using decision trees or neural network. I didn't find anything in the R documentation for functions to apply on datasets (well, English is not my mother tongue and I have some problems to understand some functions descriptions). Does anybody know where I can find anything about that ? Thank you very much, Thomas

Event sequence analysis
Dear R help, I am analyzing sequences of events described by time and a unique event tag. And I am searching for recurring patterns where patterns have to show up in a certain time window, e.g. 5 or 10 minutes. Of course, inbetween these events other events may occur. I have applied basket analysis approaches like apriori or 'frequent item set' algorithms with interesting results but
