<h2>Configuration</h2>
<p>This document uses theme <code>rmarkdown::html_vignette</code>. Its <strong>yaml</strong> section looks like this:</p>
<pre><code># ---
# title: "Recommendations for Using summarytools With Rmarkdown"
# author: "Dominic Comtois"
# date: "2019-10-19"
# output:
# rmarkdown::html_vignette:
# css:
# - !expr system.file("rmarkdown/templates/html_vignette/resources/vignette.css", package = "rmarkdown")
# vignette: >
# %\VignetteIndexEntry{Recommendations for Rmarkdown}
# %\VignetteEngine{knitr::rmarkdown}
# %\VignetteEncoding{UTF-8}
# ---</code></pre>
<p>The following <strong>summarytools global options</strong> have been set. More of them can be useful, but this is a good starting point.</p>
<div class="sourceCode" id="cb3"><pre class="sourceCode r"><code class="sourceCode r"><span id="cb3-1"><a href="#cb3-1"></a><span class="kw">st_options</span>(<span class="dt">bootstrap.css =</span> <span class="ot">FALSE</span>, <span class="co"># Already part of the theme so no need for it</span></span>
<span id="cb3-2"><a href="#cb3-2"></a> <span class="dt">plain.ascii =</span> <span class="ot">FALSE</span>, <span class="co"># One of the essential settings</span></span>
<span id="cb3-3"><a href="#cb3-3"></a> <span class="dt">style =</span> <span class="st">"rmarkdown"</span>, <span class="co"># Idem.</span></span>
<span id="cb3-4"><a href="#cb3-4"></a> <span class="dt">dfSummary.silent =</span> <span class="ot">TRUE</span>, <span class="co"># Suppresses messages about temporary files</span></span>
<span id="cb3-5"><a href="#cb3-5"></a> <span class="dt">footnote =</span> <span class="ot">NA</span>, <span class="co"># Keeping the results minimalistic</span></span>
<span id="cb3-6"><a href="#cb3-6"></a> <span class="dt">subtitle.emphasis =</span> <span class="ot">FALSE</span>) <span class="co"># For the vignette theme, this gives</span></span>
<span id="cb3-7"><a href="#cb3-7"></a> <span class="co"># much better results. Your mileage may vary.</span></span></code></pre></div>
<p>Also, the following <strong>knitr chunk options</strong> were set this way:</p>
<div class="sourceCode" id="cb4"><pre class="sourceCode r"><code class="sourceCode r"><span id="cb4-1"><a href="#cb4-1"></a><span class="kw">library</span>(knitr)</span>
<span id="cb4-2"><a href="#cb4-2"></a>opts_chunk<span class="op">$</span><span class="kw">set</span>(<span class="dt">comment=</span><span class="ot">NA</span>, <span class="dt">prompt=</span><span class="ot">FALSE</span>, <span class="dt">cache=</span><span class="ot">FALSE</span>, <span class="dt">echo=</span><span class="ot">TRUE</span>, <span class="dt">results=</span><span class="st">'asis'</span>)</span></code></pre></div>
<p>Finally, <strong>summarytools’ CSS</strong> has been included in the following manner, with chunk option <code>echo = FALSE</code>:</p>
<div class="sourceCode" id="cb5"><pre class="sourceCode r"><code class="sourceCode r"><span id="cb5-1"><a href="#cb5-1"></a><span class="kw">st_css</span>()</span></code></pre></div>
</div>
<div id="demo-examples" class="section level2">
<h2>Demo / Examples</h2>
<p>Below are examples using recommended styles for <em>Rmarkdown</em> rendering. Available styles in summarytools are the same as <code>pander</code>’s:</p>
<ul>
<li><em>simple</em> (default)<br />
</li>
<li><em>rmarkdown</em><br />
</li>
<li><em>grid</em><br />
</li>
<li><em>multiline</em></li>
</ul>
<p>For <code>freq()</code>, <code>descr()</code> (and <code>ctable()</code>, although with caveats), <em>rmarkdown</em> style is recommended. For<code>dfSummary()</code>, <em>grid</em> is recommended.</p>
<p>Starting with <code>freq()</code>, we’ll review the recommended methods and styles to quickly get satisfying results in your <em>Rmarkdown</em> documents.</p>
