<h2 class="hasAnchor" id="details"><a class="anchor" href="#details"></a>Details</h2>
<p>At default, the names of antibiotics will be shown on the plots using <code><a href='ab_property.html'>ab_name()</a></code>. This can be set with the <code>translate_ab</code> parameter. See <code><a href='count.html'>count_df()</a></code>.</p><h3 class='hasAnchor' id='arguments'><a class='anchor' href='#arguments'></a>The functions</h3>
<p><code>geom_rsi()</code> will take any variable from the data that has an <code><a href='as.rsi.html'>rsi</a></code> class (created with <code><a href='as.rsi.html'>as.rsi()</a></code>) using <code><a href='proportion.html'>rsi_df()</a></code> and will plot bars with the percentage R, I and S. The default behaviour is to have the bars stacked and to have the different antibiotics on the x axis.</p>
<p><code>facet_rsi()</code> creates 2d plots (at default based on S/I/R) using <code><a href='https://ggplot2.tidyverse.org/reference/facet_wrap.html'>ggplot2::facet_wrap()</a></code>.</p>
<p><code>scale_y_percent()</code> transforms the y axis to a 0 to 100% range using <code><a href='https://ggplot2.tidyverse.org/reference/scale_continuous.html'>ggplot2::scale_y_continuous()</a></code>.</p>
<p><code>scale_rsi_colours()</code> sets colours to the bars: pastel blue for S, pastel turquoise for I and pastel red for R, using <code><a href='https://ggplot2.tidyverse.org/reference/scale_manual.html'>ggplot2::scale_fill_manual()</a></code>.</p>
<p><code>theme_rsi()</code> is a [ggplot2 theme][<code><a href='https://ggplot2.tidyverse.org/reference/theme.html'>ggplot2::theme()</a></code> with minimal distraction.</p>
<p><code>labels_rsi_count()</code> print datalabels on the bars with percentage and amount of isolates using <code><a href='https://ggplot2.tidyverse.org/reference/geom_text.html'>ggplot2::geom_text()</a></code>.</p>
<p><code>ggplot_rsi()</code> is a wrapper around all above functions that uses data as first input. This makes it possible to use this function after a pipe (<code>%>%</code>). See Examples.</p>
