A proof-of-concept wrapping of (an earlier version of) Vowpal Wabbit
It works. It could do with some help. And it should be updated now to use the external VowpalWabbit library which did not exists when this work was originally done. Collaborators welcome.
It was a part of CRAN from Sep 2011 to Aug 2023, sort-of grandfathered, and now archived as it also reflects older code and design choices in the interface (Boost parse_args as sole input is one, the actual core processing is all fine).
It can still be installed easily provided the system requirements (i.e. Boost) are met.
A newer attempt is in https://github.com/rvw-org/rvw. And an updated (at last) upstream web presence is at https://vowpalwabbit.org.
