cachePurge

purgeCache

Require uses caches for local Package saving, local caches of <code>available.packages</code>,
local caches of GitHub (e.g., <code>"DESCRIPTION"</code>) files, and some function calls
that are cached. This function clears all of them.

A single key function, 'Require' that makes rerun-tolerant
versions of 'install.packages' and `require` for CRAN packages, packages
no longer on CRAN (i.e., archived), specific versions of packages,
and GitHub packages. This approach is developed to create reproducible
workflows that are flexible and fast enough to use while in development stages,
while able to build snapshots once a stable package collection is found.
As with other functions in a reproducible workflow, this package
emphasizes functions that return the same result whether it is
the first or subsequent times running the function, with subsequent times being
sufficiently fast that they can be run every time without undue waiting burden on
the user or developer.

cachePurge function

<dl><dt>packages</dt>
<dd>Either a character vector of packages to install via
<code>install.packages</code>, then load (i.e., with <code>library</code>), or, for convenience,
a vector or list (using <code>c</code> or <code>list</code>) of unquoted package names to install
and/or load (as in <code>require</code>, but vectorized). Passing vectors of names may
not work in all cases, so user should confirm before relying on this behaviour
in operational code.
In the case of a GitHub package, it
will be assumed that the name of the repository is the name of the package.
If this is not the case, then pass a named character vector here, where the
names are the package names that could be different than the GitHub
repository name.</dd>
<dt>repos</dt>
<dd>The remote repository (e.g., a CRAN mirror), passed to either
<code>install.packages</code>, <code>install_github</code> or <code>installVersions</code>.</dd></dl>
