rvw 0.6.0: First release

Note: Crossposted by Ivan, James and myself.

Today Dirk Eddelbuettel, James Balamuta and Ivan Pavlov are happy to announce the first release of a reworked R interface to the Vowpal Wabbit machine learning system.

Started as a GSoC 2018 project, the new rvw package was built to give R users easier access to a variety of efficient machine learning algorithms. Key features that promote this idea and differentiate the new rvw from existing Vowpal Wabbit packages in R are:

  • A reworked interface that simplifies model manipulations (direct usage of CLI arguments is also available)
  • Support of the majority of Vowpal Wabbit learning algorithms and reductions
  • Extended data.frame converter covering different variations of Vowpal Wabbit input formats

Below is a simple example of how to use the renewed rvw’s interface:

More information is available in the Introduction and Examples sections of the wiki.

The rvw links directly to libvw and so initially we offer a Docker container in order to ship the most up to date package with everything needed.

RVowpalWabbit 0.0.13: Keeping CRAN happy

Another small RVowpalWabbit package update brings us version 0.0.13. And just like Rblpapi yesterday, we have a new RVowpalWabbit update to cope with staged installs which will be a new feature of R 3.6.0. No other changes were made No new code or features were added.

We should mention once more there is a newer, but not on CRAN, package rvw thanks to the excellent GSoC 2018 and beyond work by Ivan Pavlov (who was mentored by James and myself) so if you are into Vowpal Wabbit from R go check it out.

More information is on the RVowpalWabbit page. Issues and bugreports should go to the GitHub issue tracker.

RVowpalWabbit 0.0.12

And yet another boring little RVowpalWabbit package update, now to version 0.0.12, and still in response to the CRAN request of not writing files where we should not (as caught by new tests added by Kurt). I had misinterpreted one flag and actually instructed to examples and tests to write model files back to the installed directory. Oops. Now fixed. I also added a reusable script for such tests in the repo for everybody's perusal (but it will require Linux and bindfs).

No new code or features were added.

We should mention once more that is parallel work ongoing in a higher-level package interfacing the vw binary -- rvw -- as well as plan to redo this package via the external libraries. In that sounds interesting to you, please get in touch. I am also thinking that rvw extensions / work may make for a good GSoC 2018 project (and wrote up a short note). Again, if interested, please get in touch.

More information is on the RVowpalWabbit page. Issues and bugreports should go to the GitHub issue tracker.

RVowpalWabbit 0.0.11

Another boring little RVowpalWabbit package update to version 0.0.11 came in response to another CRAN request: We were writing temporary output (a cache file for the fit/prediction, to be precise) to a non-temporary directory, which is now being caught by new tests added by Kurt. And as this is frowned upon, we made the requested change.

No new code or features were added.

RVowpalWabbit 0.0.10

A boring little RVowpalWabbit package update to version 0.0.10 came in response to another CRAN request: We were switching directories to run tests (or examples) which is now discouraged, so we no longer do this as it turns that we can of course refer to the files directly as well. Much cleaner.

No new code or features were added.

RVowpalWabbit 0.0.9

The RVowpalWabbit package update is the third of four upgrades requested by CRAN, following RcppSMC 0.1.5 and RcppGSL 0.3.2.

This package being somewhat raw, the change was simple and just meant converting the single entry point to using Rcpp Attributes -- which addressed the original issue in passing.

No new code or features were added.
