CacheDigest

A list of all the objects (e.g., arguments) to be digested

objsToDigest

The algorithms to be used; currently available choices are
 <code>md5</code>, which is also the default, <code>sha1</code>, <code>crc32</code>,
 <code>sha256</code>, <code>sha512</code>, <code>xxhash32</code>, <code>xxhash64</code>,
 <code>murmur32</code> and <code>spookyhash</code>.

algo

a Character string, length 1, with the function to
compare with. Default is "Cache". All other values may not produce
robust CacheDigest results.

calledFrom

passed to <code>.robustDigest</code>; this is generally empty except
for advanced use.

This can be used by a user to pre-test their arguments before running
<code>Cache</code>, for example to determine whether there is a cached copy.

Collection of high-level, robust, machine- and OS-independent tools
for making deeply reproducible and reusable content in R.
The three workhorse functions are Cache, prepInputs, and Require;
these allow for nested caching, robust to environments, and objects with
environments (like functions), and data retrieval and processing, and
package handling in continuous workflow environments. In all cases,
efforts are made to make the first and subsequent calls of functions have
the same result, but vastly faster at subsequent times by way of checksums
and digesting. Several features are still under active development, including
cloud storage of cached objects, allowing for sharing between users.
