Re: [R] SVM functions
I'm not sure if you want general literature or R-specific answers. In any case, check either source below and you may have better luck contacting authors as many may use R but not be on this list. > Date: Wed, 6 Oct 2010 06:28:02 -0700 > From: nikkiha...@gmail.com > To: r-help@r-project.org > Subject: Re: [R] SVM functions > > > What are the ways by which one can validate the SVM results and its > significance?

Re: [R] SVM functions
What are the ways by which one can validate the SVM results and its significance? Are there any papers or articles regarding my question? Please do let me know.

Re: [R] SVM functions
hi, Thanks for this suggestion. svm function in e1071 is working fine. As I want multi classification, I would like to understand the differences in these packages and the results (based on the parameter). So that it would be easy to select the best package for my data. -- View this message in context: http://r.789695.n4.nabble.com/SVM-functions-tp2955768p2964777.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] SVM functions
Hi, I don't know why your package does not work, but if you only want access to an SVM, you can use the svm function in the e1071 package instead.

How to check it: Well, that depends on your OS that is unstated so far. Asking a search engine for "svmlight" points you to http://www.cs.cornell.edu/People/tj/svm_light/ from where you can get and install it.

Re: [R] SVM functions
Probably you do not have svmlight installed on your machine. Uwe Ligges On 05.10.2010 12:42, Neeti wrote: Hi !
