title: Function to filter data equal to or greater than a certain value
body: <p>I have a dataframe containing thousands of rows and columns. The rows contain the names of genes and the columns the names of samples.</p>
  <p>I only want to keep the rows that contain a value equal to or greater than 5 in more than 3 samples.</p>
  <p>I tried this so far but I can't figure out how to set multiple conditions:</p>
  <pre><code>data.frame1 %&gt;% filter_all(all_vars(.&gt;= 5))
  </code></pre>
  <p>I hope I have stated this question correctly.</p>
