digest creates hash digests of arbitrary R objects (using the 'md5', 'sha-1', 'sha-256', 'sha-512', 'crc32', 'xxhash32', 'xxhash64' and 'murmur32' algorithms) permitting easy comparison of R language objects.
Just like release 0.6.13 in December, and release 0.6.14 two weeks ago, this release accomodates a request by R Core. This time it was Kurt who improved POSIXlt extraction yesterday which required a one-line change to
sha1() summaries---which he kindly sent along. We also already had a change by Thierry who had generalized
sha1() to accept a new argument allowing sha256 and sha512 summaries to be created.
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.
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. Again, if interested, please get in touch.
