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.
