A collection of high-level, machine- and OS-independent tools
for making reproducible and reusable content in R.
The two workhorse functions are Cache() and prepInputs(). Cache()
allows for nested caching, is robust to environments and objects with
environments (like functions), and deals with some classes of
file-backed R objects e.g., from terra and raster packages.
Both functions have been developed to
be foundational components of data retrieval
and processing in continuous workflow situations. In both functions,
efforts are made to make the first and subsequent calls of functions have
the same result, but faster at subsequent times by way of checksums
and digesting. Several features are still under development, including
cloud storage of cached objects allowing for sharing between users. Several
advanced options are available, see ?reproducibleOptions().

dlGeneric function

<dl><dt>url</dt>
<dd>The url (link) to the file.</dd>
<dt>destinationPath</dt>
<dd>Character string of a directory in which to download
and save the file that comes from <code>url</code> and is also where the function
will look for <code>archive</code> or <code>targetFile</code>. NOTE (still experimental):
To prevent repeated downloads in different locations, the user can also set
<code>options("reproducible.inputPaths")</code> to one or more local file paths to
search for the file before attempting to download. Default for that option is
<code>NULL</code> meaning do not search locally.</dd>
<dt>verbose</dt>
<dd>Numeric, -1 silent (where possible), 0 being very quiet,
1 showing more messaging, 2 being more messaging, etc.
Default is 1. Above 3 will output much more information about the internals of
Caching, which may help diagnose Caching challenges. Can set globally with an
option, e.g., <code>options('reproducible.verbose' = 0) to reduce to minimal</code></dd></dl>
