(Legacy) R interface to Vowpal Wabbit
Vowpal Wabbit is a fast on-line learner built by John Langford and others, initially at Yahoo! Research and now at Microsoft Research
This rvw-legacy package builds upon the skeleton r.vw package in the Vowpal Wabbit sources. It has streamlined the packaging and added a few things here and there.
The newer rvw package offers a fresher and more powerful approach leveraging the Vowpal Wabbit library rather than calling the binary.
You will need the vw binary in your path. On Debian / Ubuntu systems to
sudo apt-get install vowpal-wabbiitOn other systems follow the Vowpal Wabbit instructions.
Several demos are included in the demo/ directory and accessible (once installed) via the demo() function. Here
are tow figures from demo/vw_example_4.r which revisits the Titanic dataset.
Now mostly dormant as rvw offers a fresher approach.
