Character string indicating minimum version of package
that is needed

minVersion

A character string with a prefix of message to provide

messageStart

This provides a standard message format for missing packages, e.g.,
detected via <code>requireNamespace</code>.

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.
