<p>The input of <code>x</code>, possibly with edited values of antibiotics. Or, if <code>verbose = TRUE</code>, a <code><a href='https://rdrr.io/r/base/data.frame.html'>data.frame</a></code> with all original and new values of the affected bug-drug combinations.</p>
<h2 class="hasAnchor" id="details"><a class="anchor" href="#details"></a>Details</h2>
<p><strong>Note:</strong> This function does not translate MIC values to RSI values. Use <code><a href='as.rsi.html'>as.rsi()</a></code> for that. <br />
<strong>Note:</strong> When ampicillin (AMP, J01CA01) is not available but amoxicillin (AMX, J01CA04) is, the latter will be used for all rules where there is a dependency on ampicillin. These drugs are interchangeable when it comes to expression of antimicrobial resistance.</p>
<p>Before further processing, some non-EUCAST rules can be applied to improve the efficacy of the EUCAST rules. These non-EUCAST rules, that are then applied to all isolates, are:</p><ul>
<li><p>Inherit amoxicillin (AMX) from ampicillin (AMP), where amoxicillin (AMX) is unavailable;</p></li>
<li><p>Inherit ampicillin (AMP) from amoxicillin (AMX), where ampicillin (AMP) is unavailable;</p></li>
<li><p>Set amoxicillin (AMX) = R where amoxicillin/clavulanic acid (AMC) = R;</p></li>
<li><p>Set piperacillin (PIP) = R where piperacillin/tazobactam (TZP) = R;</p></li>
<li><p>Set trimethoprim (TMP) = R where trimethoprim/sulfamethoxazole (SXT) = R;</p></li>
<li><p>Set amoxicillin/clavulanic acid (AMC) = S where amoxicillin (AMX) = S;</p></li>
<li><p>Set piperacillin/tazobactam (TZP) = S where piperacillin (PIP) = S;</p></li>
<li><p>Set trimethoprim/sulfamethoxazole (SXT) = S where trimethoprim (TMP) = S.</p></li>
</ul>
<p>These rules are not applied at default, since they are not approved by EUCAST. To use these rules, please use <code>eucast_rules(..., rules = "all")</code>, or set the default behaviour of the <code>[eucast_rules()]</code> function with <code><a href='https://rdrr.io/r/base/options.html'>options(AMR.eucast_rules = "all")</a></code> (or any other valid input value(s) to the <code>rules</code> parameter).</p>
<p>The file containing all EUCAST rules is located here: <a href='https://gitlab.com/msberends/AMR/blob/master/data-raw/eucast_rules.tsv'>https://gitlab.com/msberends/AMR/blob/master/data-raw/eucast_rules.tsv</a>.</p>
<h2 class="hasAnchor" id="antibiotics"><a class="anchor" href="#antibiotics"></a>Antibiotics</h2>
<p>To define antibiotics column names, leave as it is to determine it automatically with <code><a href='guess_ab_col.html'>guess_ab_col()</a></code> or input a text (case-insensitive), or use <code>NULL</code> to skip a column (e.g. <code>TIC = NULL</code> to skip ticarcillin). Manually defined but non-existing columns will be skipped with a warning.</p>
<p>The following antibiotics are used for the functions <code>eucast_rules()</code> and <code><a href='mdro.html'>mdro()</a></code>.
