<section id="whats-ggplotplus-for" class="level2">
<h2 class="anchored" data-anchor-id="whats-ggplotplus-for">What’s <code>ggplotplus</code> for?</h2>
<p><code>ggplot2</code> is an <em>extraordinarily</em> powerful graphics package, used by perhaps millions to produce graphs for posters, presentations, papers, and exploration. <code>ggplotplus</code> enhances <code>ggplot2</code> by:</p>
<ol type="1">
<li><p>Providing tools that override many of <code>ggplot2</code>’s less-than-fully-accessible default design aspects so creating graphs that adhere to design best practices is easier and quicker.</p></li>
<li><p>Enabling some design options–such as custom point shapes in scatterplots, direct group labeling, and relocation of the y-axis title–that are currently impossible via a single function call in <code>ggplot2</code>.</p></li>
<li><p>Attempting to lower the learning curve and bandwidth required to make high-quality, Universal-Design-oriented graphs, ready for publication and sharing, using <code>ggplot2</code>.</p></li>
</ol>
<p>In particular, <code>ggplotplus</code> is for anyone who wants or needs to use <code>ggplot2</code> but has limited time, skill, energy, patience, experience, etc. with which to devote to learning its many nuances. However, given its evidence-based approach to graph design, the package is for everyone who wants to build defensible, maximally consumable graphs quickly and with a fraction of the fiddly customization often required to get a typical ggplot up to the most exacting design standards. Plus, <code>ggplotplus</code> has a few tricks to offer that, at present, aren’t available via a single function call anywhere else–read on for details!</p>
</section>
<section id="quick-start-guide" class="level2">
<h2 class="anchored" data-anchor-id="quick-start-guide">Quick Start Guide</h2>
<p>To begin using <code>ggplotplus</code>, first install the latest development version from GitHub using the pak package:</p>
<div class="cell">
<div class="code-copy-outer-scaffold"><div class="sourceCode cell-code" id="cb1"><pre class="sourceCode r code-with-copy"><code class="sourceCode r"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="co"># install.packages("devtools") #IF NOT ALREADY INSTALLED</span></span>
<span id="cb1-2"><a href="#cb1-2" aria-hidden="true" tabindex="-1"></a>pak<span class="sc">::</span><span class="fu">pak</span>(<span class="st">"MAISRC/ggplotplus"</span>)</span></code></pre></div><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></div>
</div>
<p>Or, alternatively, install the latest stable version from CRAN:</p>
<div class="cell">
<div class="code-copy-outer-scaffold"><div class="sourceCode cell-code" id="cb2"><pre class="sourceCode r code-with-copy"><code class="sourceCode r"><span id="cb2-1"><a href="#cb2-1" aria-hidden="true" tabindex="-1"></a><span class="fu">install.packages</span>(<span class="st">"ggplotplus"</span>)</span></code></pre></div><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></div>
</div>
<p>Then, load it alongside <code>ggplot2</code>:</p>
<div class="cell">
<div class="code-copy-outer-scaffold"><div class="sourceCode cell-code" id="cb3"><pre class="sourceCode r code-with-copy"><code class="sourceCode r"><span id="cb3-1"><a href="#cb3-1" aria-hidden="true" tabindex="-1"></a><span class="co"># install.packages("ggplot2") #IF NOT ALREADY INSTALLED</span></span>
<span id="cb3-2"><a href="#cb3-2" aria-hidden="true" tabindex="-1"></a><span class="fu">library</span>(ggplot2)</span>
<span id="cb3-3"><a href="#cb3-3" aria-hidden="true" tabindex="-1"></a><span class="fu">library</span>(ggplotplus)</span></code></pre></div><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></div>
</div>
<p>Once loaded, you can start layering its <code>_plus()</code> tools onto your <code>ggplot2</code> calls to improve their design quickly and with minimal effort!</p>
<section id="using-the-tools" class="level3">
<h3 class="anchored" data-anchor-id="using-the-tools">Using the tools</h3>
<p>Here’s a basic, default <code>ggplot2</code> as a point of comparison:</p>
<div class="cell">
<div class="code-copy-outer-scaffold"><div class="sourceCode cell-code" id="cb4"><pre class="sourceCode r code-with-copy"><code class="sourceCode r"><span id="cb4-1"><a href="#cb4-1" aria-hidden="true" tabindex="-1"></a><span class="fu">ggplot</span>(iris, </span>
<span id="cb4-2"><a href="#cb4-2" aria-hidden="true" tabindex="-1"></a> <span class="at">mapping =</span> <span class="fu">aes</span>(<span class="at">x =</span> Petal.Length, </span>
<span id="cb4-3"><a href="#cb4-3" aria-hidden="true" tabindex="-1"></a> <span class="at">y =</span> Sepal.Length)) <span class="sc">+</span></span>
<span id="cb4-4"><a href="#cb4-4" aria-hidden="true" tabindex="-1"></a> <span class="fu">geom_point</span>(<span class="at">mapping =</span> <span class="fu">aes</span>(<span class="at">color =</span> Species)) </span></code></pre></div><button title="Copy to Clipboard" class="code-copy-button"><i class="bi"></i></button></div>
<div class="cell-output-display">
<div>
<figure class="figure">
<p><img src="README_files/figure-html/point%20of%20comparison-1.png" class="img-fluid figure-img" width="672"></p>
</figure>
</div>
</div>
</div>
<p>The biggest single change you can make to the design of your graphs via <code>ggplotplus</code> is via its <code>theme_plus()</code> function, which overrides a suite of <code>ggplot2</code>’s default design choices related to default color palettes, common geometry layers, and layout parameters:</p>
<div class="cell">
<div class="code-copy-outer-scaffold"><div class="sourceCode cell-code" id="cb5"><pre class="sourceCode r code-with-copy"><code class="sourceCode r"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a><span class="fu">ggplot</span>(iris, </span>

<p>The above graphs demonstrates how <code>ggplotplus</code>’s tools rethink the default design features of <code>ggplot2</code>. The intention is to yield a more universal product more quickly so you can spend less time fiddling with your graphs and more time sharing them with a wider audience.</p>
<p>However, there’s a <em>lot</em> more to know! If you want to dive deeper, <a href="https://maisrc.github.io/ggplotplus/">check out the full package cookbook</a>.</p>

<p><code>ggplotplus</code> is under active development. All current core functions are expected to remain relatively stable, but some parameters, features, and default settings may evolve, and addressing bugs, inconsistencies, and gaps remains a high priority. User discretion and feedback is advised! Please don’t hesitate to share bug reports or questionable performance issues via the Issues feature on the package’s Github page.</p>
