title: X-axis sub-labels in ggplot R
body: <p>I have the following ggplot code that renders the box plot show below.</p>
  <pre><code>ggplot(comparisonData, aes(Group,score)) + 
    geom_boxplot(notch = TRUE, varwidth = TRUE, aes(colour = Group)) +
    geom_jitter(width = 0.2, aes(colour = Group)) + 
    theme(legend.position = &quot;none&quot;) + 
    labs(title=&quot;User Engagement Score&quot;, x=&quot;Condition&quot;, y=&quot;Score (max 140)&quot;)
  </code></pre>
  <p>In this plot I want the groups 1 and 2 on the x-axis to be renamed as &quot;Stealth&quot; and &quot;Non-stealth&quot;, but I am not able to find a way to do so. Is it possible without changing the group names in data?</p>
