title: Use an external list to remove data from rows
body: <p>I have a data frame</p>
  
  <pre><code>df &lt;- data.frame(
      A = c(4, 2, 7),
      B = c(3, 3, 5),
      C = c("Expert,Foo", "Bar,Wild", "Zap")
    )
  </code></pre>
  
  <p>and a second one which I would like to use as index to remove rows which contain the specific values</p>
  
  <pre><code>mylist &lt;- data.frame(rtext = c("Foo","Bar"))
  </code></pre>
  
  <p>So I tried this:</p>
  
  <pre><code>subset(df, C %in% mylist$rtext)
  </code></pre>
  
  <p>How can I remove the specific rows?</p>
