In rvw-org/rvw-legacy: Minimal Interface Between R and Vowpal Wabbit

rvw-legacy

(Legacy) R interface to Vowpal Wabbit

What is 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

What does rvw-legacy do?

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.

Requirements

You will need the vw binary in your path. On Debian / Ubuntu systems to

sudo apt-get install vowpal-wabbiit

On other systems follow the Vowpal Wabbit instructions.

Examples

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.

Status

Now mostly dormant as rvw offers a fresher approach.
