mlr3oml-package

Provides an interface to 'OpenML.org' to list and
 download machine learning data and tasks. Data and tasks can be
 automatically converted to 'mlr3' tasks. For a more sophisticated
 interface which also allows uploading experiments, see the 'OpenML'
 package.

For the former you may pass either a <code>data_id</code> or a <code>task_id</code>, the latter requires
a <code>task_id</code>.

mlr3 Integration

<ul>
<li><code>mlr3oml.cache</code>: Enables or disables caching globally.
If set to <code>FALSE</code>, caching is disabled.
If set to <code>TRUE</code>, cache directory as reported by <code><a rd-options="=R_user_dir" href="/link/R_user_dir()?package=mlr3oml&version=0.2.0&to=%3DR_user_dir" data-mini-rdoc="=R_user_dir::R_user_dir()">R_user_dir()</a></code> is used.
Alternatively, you can specify a path on the local file system here.
Default is <code>FALSE</code>.</li>
<li><code>mlr3oml.api_key</code>: API key to use. All operations supported by this package
work without an API key, but you might get rate limited without an API key.</li>
</ul>
