title: Boxplots with ggpaired() WITHOUT connecting lines
body: <p>I have a large dataset and would like to plot boxplots of two paired samples using ggpaired(). However, ggpaired() automatically adds connecting lines between the samples. Because I have lots of observations, this looks ridiculous and I would like to just get rid of the lines. I tried setting the
  line.size = 0 or
  line.color = &quot;white&quot;
  etc.</p>
  <p>However, I am not able to plot the boxplots without the lines. Does anyone know how this can be fixed, or does anybody know a package that allows me to do so? Your help is appreciated!!</p>
  <p>Sample code:</p>
  <pre class="lang-r prettyprint-override"><code>ggpaired(ToothGrowth, x = &quot;supp&quot;, y = &quot;len&quot;, color = &quot;supp&quot;, 
           line.color = &quot;gray&quot;, line.size = 0.4, palette = &quot;jco&quot;)+ 
   stat_compare_means(paired = TRUE) 
  </code></pre>
