title: Need to count character
body: <p>I have a <code>dataframe LoopVariable</code> and the following couple of lines of code:</p>
  
  <pre><code>print(unique(LoopVariable[,"Job..R"]))
  [1] "14047/2" "18331/3"
  </code></pre>
  
  <p>My output are two character and that is all good. My question now is: How can I count my output for further calculation usage? In other words: I have two characters and I need them to be as an integer for further calculation usage. In my example here the integer value would be <code>"2"</code>.</p>
