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 -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

There is classification tree support in packages rpart and tree, and neural nets support in package nnet in the VR bundle. -- Brian D.

If your aim is to try out a large number of machine learning algorithms (as opposed to looking for the ones you mention specifically) you may find the free Weka package of interest: http://www.cs.waikato.ac.nz/~ml/weka/ On 10 Mar 2002 at 15:54, Thomas DEGRIS wrote:> I would like to test some learning algorithms (C5.0, or C4.5) using decision trees or neural network.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

Hi, (IMHO) there is currently no package for C4.5/C5.0 in R. But you can use Rpart package which is very similar to CART ( Classification And Regression Tree - Breimann) ...and when anybody want use a really fast C4.5 and apriori algorithm - try: http://fuzzy.cs.uni-magdeburg.de/~borgelt/software.html ...i'm really surprised that currently no "Association-Rule" package is implemented in R, too and would share this intention to do with others ( for learning programming in R faster ). regards, Christian Schulz Am 10.03.2002 19:43:58, schrieb ggrothendieck at yifan.net:> >If your aim is to try out a large number of machine learning algorithms >(as opposed to looking for the ones you mention specifically) you mayreally >find the free Weka package of interest > >http://www.cs.waikato.ac.nz/~ml/weka/ > > >On 10 Mar 2002 at 15:54, Thomas DEGRIS wrote: > >> I would like to test some learning algorithms (C5.0, or C4.5) using decision trees or neural network. > >-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- >r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html >Send "info", "help", or "[un]subscribe" >(in the "body", not the subject !)

Hello, I thank people who helped me about the learning algorithms of R. I managed to use the "nnet" and "rpart" packages successfully [;-)] The thing is that I don't know which methods they use. Because I am writing a report on what I did with them, I'd like to know the actual names of these. I may appear stupid but I didn't find any known name in the documentation. Thank you very much.

thomas, download http://hesweb1.med.virginia.edu/biostat/s/techrep.pdf and you get a really nice introduction for Rpart and in Chapter 11 you find Relation to other porgramms . ...sometimes i compare the results between C4.5R8 and Rpart which are more or less the same, but i can interpret the results with Rpart better ! regards,christian Thomas wrote:> Hello, > > I thank people who helped me about the learning algorithms of R. > I managed to use the "nnet" and "rpart" packages successfully [;-)] > The thing is that I don't know which methods they use. > Because I am writing a report on what I did with them, I'd like to > know the actual names of these. > I may appear stupid but I didn't find any known name in the > documentation. > > Thank you very much. > > Thomas. > > > > Thomas DEGRIS wrote: > >> 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).

Hello, I just wanted to thank you everybody who helped me with R. I finished for the moment to use it but we never know I may come back to it one day...
