title: R ggplot: confidence interval plot
body: <p>I have some <a href="https://drive.google.com/file/d/1LmruANHu-qWN8iDuqMvCU3NW_3cxBwM-/view?usp=sharing" rel="nofollow noreferrer">data</a>, and I want to plot confidence interval using <code>ggplot</code>'s <code>stat_summary</code>.</p>
  <p>My code looks like this:</p>
  <pre><code>file &lt;- read.csv(filepath)
  ggplot(file, aes(shop, income, colour = season)) + stat_summary(size = 0.8)
  </code></pre>
  <p><a href="https://i.stack.imgur.com/DkT1l.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DkT1l.png" alt="enter image description here" /></a></p>
  <p>But I want to get something like this:</p>
  <p><a href="https://i.stack.imgur.com/ejml7.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ejml7.png" alt="enter image description here" /></a></p>
  <p>So my questions are:</p>
  <ol>
  <li>How can I change names of &quot;shop&quot; columns?</li>
  <li>How can I change length of summary lines?</li>
  <li>How can I set distance between two datalines in one column?</li>
  </ol>
