<p>All output <ahref="translate.html">will be translated</a> where possible.</p>
<p>The function <code>ab_url()</code> will return the direct URL to the official WHO website. A warning will be returned if the required ATC code is not available.</p>
<p>The function <code>set_ab_names()</code> is a special column renaming function for <ahref="https://rdrr.io/r/base/data.frame.html"class="external-link">data.frame</a>s. It renames columns names that resemble antimicrobial drugs. It always makes sure that the new column names are unique. If <code>property = "atc"</code> is set, preference is given to ATC codes from the J-group.</p>
The <ahref="lifecycle.html">lifecycle</a> of this function is <strong>stable</strong>. In a stable function, major changes are unlikely. This means that the unlying code will generally evolve by adding new arguments; removing arguments or changing the meaning of existing arguments will be avoided.</p>
<p>If the unlying code needs breaking changes, they will occur gradually. For example, an argument will be deprecated and first continue to work, but will emit a message informing you of the change. Next, typically after at least one newly released version on CRAN, the message will be transformed to an error.</p>
