On-line machine learning packages?
Hi Jay, I see this thread is a bit (ok, quite) old at this point, but I see you never really got an answer to your question that was satisfactory. I figured you might be interested to know that Dirk has started to wrap vowpal wabbit[1,2] into an R package, RVowpalWabbit[3,4] The package itself is still a rather bare-bones, but perhaps it can be useful to you in its current state, or perhaps the "raw" vowpal wabbit. You might also consider the shogun toolbox[5]. As of its 1.0 release, I believe it has incorporated vowpal wabbit in some form or another to do online learning, but might have other online learning algos baked in. It has its own flavor of an R interface (r_static or r_modular), which might work for you if you can get it to compile. -steve [1] Vowpal Wabbit (home page): http://hunch.net/~vw/ [2] Vowpal Wabbit (github): https://github.com/JohnLangford/vowpal_wabbit [3] RVowpalWabbit (CRAN): http://cran.r-project.org/web/packages/RVowpalWabbit/index.html [4] RVowpalWabbit (R-forge): https://r-forge.r-project.org/projects/rvowpalwabbit/ [5] The shogun toolbox: http://www.shogun-toolbox.org/

In my mind this sequential classification task with feedback is somewhat different from an completely offline, once-off, classification. Am I wrong? However, it looks like the mentality on this topic is to refer me to cran/google in order to look for solutions myself. Oblivious I know about these sources, and as I said, I used rseek.org among other sources to look for solutions. I did not start this topic for fun, I'm asking for help to find a suitable machine learning packages that readily incorporates feedback loops and online learning. If somebody has experience these kinds of problems in R, please respond. Or will "http://cran.r-project.org Look for 'Task Views'" be my next piece of advice?

If the answer is so obvious, could somebody please spell it out?

Hi,
I used the rseek search engine to look for suitable solutions, however as I was unable to find anything useful, I'm asking for help. Anybody have experience with these kinds of problems? I looked into dynaTree, but as information is a bit scares and as I understand it, it might not be what I'm looking for..(?)
BR, Jay

What R packages are available for performing classification tasks? That is, when the predictor has done its job on the dataset (based on the training set and a range of variables), feedback about the true label will be available and this information should be integrated for the next classification round.
You should look at CRAN Task Views. Extremely easy to find from the main R-project page.
