title: Plot multiple variables by year in the same bar plot
body: <p>I am having trouble figuring out how to create a specific style of plot in ggplot.</p>
  <p>I have data in a tibble that looks like this:</p>
  <pre><code>indicator   2015   2019
  
  wdi_lfpr    55.6   58.2
  wdi_lfprf   34.9   38.2
  wdi_lfprm   77.0   78.4
  </code></pre>
  <p>The values under each year are percents. I would like to plot these so that each indicator appears side by side, and shows values for each year (2015, 2019).<a href="https://i.stack.imgur.com/Tw6hX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Tw6hX.png" alt="example of desired graph" /></a></p>
  <p>I can't figure out how to go about this in ggplot. Thank you for any help.</p>
  <p>EDIT: Thanks to advice from commenters, I have reshaped my data to this format:</p>
  <pre><code>indicator   year    value
  wdi_lfpr    2015    55.6 
  wdi_lfprm   2015    34.9 
  wdi_lfprf   2015    77.0
  wdi_lfpr    2019    58.2
  wdi_lfprm   2019    58.2
  wdi_lfprf   2019    58.2
  </code></pre>
