<p>De nombreuses extensions permettent d’étendre les possibilités graphiques de <code class="pkg">ggplot2</code>. Certaines ont déjà été abordées dans les différents chapitres d’<strong>analyse-R</strong>. Le présent chapitre ne se veut pas exhaustif et ne présente qu’une sélection choisie d’extensions.</p>
<p>Le site <strong>ggplot2 extensions</strong> (<a href="https://exts.ggplot2.tidyverse.org/gallery/" class="uri">https://exts.ggplot2.tidyverse.org/gallery/</a>) recense diverses extensions pour <code class="pkg">ggplot2</code>.</p>
<p>Pour une présentation des fonctions de base et des concepts de <code class="pkg">ggplot2</code>, on pourra se référer au <a href="ggplot2.html">chapitre dédié</a> ainsi qu’au deux chapitres introductifs : <a href="intro-ggplot2.html">introduction à ggplot2</a> et <a href="graphiques-bivaries-ggplot2.html">graphiques bivariés avec ggplot2</a>.</p>
<p>Pour trouver l’inspiration et des exemples de code, rien ne vaut l’excellent site <a href="https://www.r-graph-gallery.com/" class="uri">https://www.r-graph-gallery.com/</a>.</p>

<p>Lorsque l’on affiche des étiquettes de texte, ces dernières peuvent se supperposer lorsqu’elles sont proches.
