installedVersions

Character vector of packages to determine which version is
installed in the <code>libPath</code>.

packages

The library path where all packages should be installed, and looked for to load
(i.e., call <code>library</code>)

libPath

This code is adapted from <code><a rd-options="versions" href="/link/installed.versions?package=reproducible&version=1.1.1&to=versions" data-mini-rdoc="versions::installed.versions">installed.versions</a></code>.
It will be anywhere from 2x to 10x faster than the
<code><a rd-options="versions" href="/link/installed.versions?package=reproducible&version=1.1.1&to=versions" data-mini-rdoc="versions::installed.versions">installed.versions</a></code> function.
This is also many times faster than <code>utils::installed.packages</code>,
especially if only a subset of "all" packages in <code>libPath</code> are desired
(1000x ? for the 1 package case).

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.

installedVersions function

This code is adapted from <code><a rd-options='versions' href='installed.versions'>installed.versions</a></code>.
It will be anywhere from 2x to 10x faster than the
<code><a rd-options='versions' href='installed.versions'>installed.versions</a></code> function.
This is also many times faster than <code>utils::installed.packages</code>,
especially if only a subset of "all" packages in <code>libPath</code> are desired
(1000x ? for the 1 package case).
