Writes a <code><a href="/link/data.frame()?package=mlr3oml&version=0.9.0" data-mini-rdoc="mlr3oml::data.frame()">data.frame()</a></code> to an ARFF file.
Limitations:<ul>
<li>Logicals are written as categorical features.</li>
<li><a href="/link/POSIXct?package=mlr3oml&version=0.9.0" data-mini-rdoc="mlr3oml::POSIXct">POSIXct</a> columns are converted to UTC.</li>
</ul>

Provides an interface to 'OpenML.org' to list and download
machine learning data, tasks and experiments. The 'OpenML' objects can
be automatically converted to 'mlr3' objects.  For a more
sophisticated interface with more upload options, see
the 'OpenML' package.
