.guessAtTargetAndFun

internal

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()'.

guessAtTarget function

<dl><dt>destinationPath</dt>
<dd>Full path of the directory where the target file should be</dd>
<dt>filesExtracted</dt>
<dd>A character vector of all files that have been extracted (e.g.,
from an archive)</dd>
<dt>messageGuessing</dt>
<dd>Logical. If <code>TRUE</code> (the default, used when a load will
follow, e.g. from <code>prepInputs</code>), emit the messages about the guessed
<code>targetFile</code>/<code>fun</code> (e.g. "targetFile was not specified", "Picking the last
one"). A direct <code>preProcess()</code> call sets this to <code>FALSE</code> because it never
loads the object, so those messages would be misleading; the guessing
itself (and the returned values) is unchanged.</dd></dl>
