Dear all, I have just found a 'good' tutorial R for datamining. I think it should be on the contributed docs. http://cran.r-project.org/other-docs.html Here is the link http://www.liaad.up.pt/~ltorgo/DataMiningWithR/ What do you think? Kind regards Christophe -- Christophe Dutang Ph. D. student at ISFA, Lyon, France website: http://dutangc.free.fr

I'm reading Torgo (2010) *Data Mining with R*<http://www.liaad.up.pt/~ltorgo/DataMiningWithR/code.html>in preparation for a class I'll be teaching next quarter. Here's an example that is very non-functional. > pH <- c(4.5,7,7.3,8.2,6.3) > names(pH) <- c('area1','area2','mud','dam','middle') > pH area1 area2 mud dam...

Hi r-people :) I'm sorry to disturb but I must admit that I know amazingly little about R and similar statistics-packages/languages and I'm kind of lost on where to start. I'm currently working on a datacollection framework for postgresql (The db doesn't really matter except that I hope to use PL/R) and I would like to be able to predict future values preferable 1 day or more

...re S3 and S3 category objects. Is there a good introductory description of how these are different from standard R objects and how they are different from each other? Also, how does one find out more about how objects are declared. For example, Data Mining with R<http://www.liaad.up.pt/~ltorgo/DataMiningWithR/code3.html>uses the quantmod package. I am used to Java's JavaDoc where one can see how classes are declared, what the instance variables and methods are, etc. I don't see anything similar for this package. How, for example, would one find out what the instance variables are in a quantm...

Deall all, We need to perform a statistical analysis of a large database (40,000 entries with approximately 500 fields in each entry) currently handled in Oracle. The data contains categorical variables only. At the current stage we suggest classification and clustering analysis. We are planning to perform the analysis in R and would be very grateful for any

Dear R-user, I wish to know if someone is using R as concern Datamining or KDD (Knowledge Discovery in Database) and if already exists a R package specialized in this kind of analysis. I found this contributes on the R web site: [20] Diego Kuonen. Introduction au data mining avec R : vers la reconqu??te du `knowledge discovery in databases' par les statisticiens. Bulletin of the Swiss

Hello all, Im just beggining using R. I have read a couple of introductory documents but they are very general. Is there a document focused on classification? (this is what Ill be using R for). Examples would be just fine. Thanks in advance, Ulises

Are there any packages in R that are suitable for doing time series forecasting using neural networks? I have looked in the nnet package and neural package and they both seem geared towards classification. thanks, Spencer [[alternative HTML version deleted]]

Hi All, I am interested in learning about people's experience with R training or courses. What worked, what didn't? What do you recommend? Also, if there any groups or individuals that have and can offer R training courses, please contact me directly. I would like to learn about your services. Thanks for your input and help. Please feel free to contact me directly. Russ

R people, I need to know if is possible to make data mining with R. If so, is there any manual or somewhere/one to consult about that. Thank you very much Adri?n

Hi, how can I import really big plain text data files (several GB) from an ERP-System (SAP-Tables) to R? The Header of these files are always similar, for example: Tabelle: T009 Angezeigte Felder: 7 von 7 Feststehende F??hrungsspalten: 2 Listbreite 0250 ---------------------------------------------------------------------- |X|MANDT|PERIV|XKALE|XJABH|ANZBP|ANZSP|LTEXT

I've got a PhD student starting this year. She'll be working on data mining. She has asked for a reading list while she's still in her home country, which is a really good sign. Her cosupervisor and I don't (think we) have any problem with choosing things that are specifically about data mining, but there are some statistical ideas (sampling, exploratory-vs-confirmatory,
