  <pre><code>dataframe &lt;- c (1,1.2,40,1000,36.66,400.55,100,99,2,1500,333.45,25,125.66,141,5,87,123.2,61,93,85,40,205,208.9)
  </code></pre>

  <p>Update</p>
  <p>Following the guidance of the colleague I am updating the question.</p>
  <p>I have a data base and I would like to calculate the frequency that a given value of that base appears within a pre-defined range, for example: 0-50, 50-150, 150-500, 500-2000.</p>
  <p>in the post(<a href="https://stackoverflow.com/questions/65056651/how-to-create-a-frequency-histogram-with-predefined-non-uniform-intervals">how to create a frequency histogram with predefined non-uniform intervals?</a>) I managed to do this, but I don't know how to add the labels above the bars. I Tried:</p>
  <p><code>barplort (data, labels = labels)</code>, but it didn't work.</p>
  <p>I used barplot because the post recommended me, but if it is possible to do it using ggplot, it would be good too.</p>
