<td><p>an antimicrobial class, like <code>"carbapenems"</code>. The columns <code>group</code>, <code>atc_group1</code> and <code>atc_group2</code> of the <a href='antibiotics.html'>antibiotics</a> data set will be searched (case-insensitive) for this value.</p></td>

<h2 class="hasAnchor" id="details"><a class="anchor" href="#details"></a>Details</h2>
<p>All columns will be searched for known antibiotic names, abbreviations, brand names and codes (ATC, EARS-Net, WHO, etc.). This means that a selector like e.g. <code>aminoglycosides()</code> will pick up column names like 'gen', 'genta', 'J01GB03', 'tobra', 'Tobracin', etc.</p>
<p>These functions only work if the <code>tidyselect</code> package is installed, that comes with the <code>dplyr</code> package. An error will be thrown if <code>tidyselect</code> package is not installed, or if the functions are used outside a function that allows Tidyverse selections like <code><a href='https://dplyr.tidyverse.org/reference/select.html'>select()</a></code> or <code>pivot_longer()</code>.</p>
