rank_results

This function sorts the results by a specific performance metric.

A workflow is a combination of a model and preprocessors
(e.g, a formula, recipe, etc.) (Kuhn and Silge (2021)
<https://www.tmwr.org/>). In order to try different combinations of
these, an object can be created that contains many workflows. There
are functions to create workflows en masse as well as training them
and visualizing the results.

rank_results function

<dl><dt>x</dt>
<dd>A <code>workflow_set</code> object that has been evaluated
with <code>workflow_map()</code>.</dd>
<dt>rank_metric</dt>
<dd>A character string for a metric.</dd>
<dt>eval_time</dt>
<dd>A single numeric time point where dynamic event time
metrics should be chosen (e.g., the time-dependent ROC curve, etc). The
values should be consistent with the values used to create <code>x</code>. The <code>NULL</code>
default will automatically use the first evaluation time used by <code>x</code>.</dd>
<dt>select_best</dt>
<dd>A logical giving whether the results should only contain
the numerically best submodel per workflow.</dd></dl>
