title: Manipulate string in R
body: <p>I'm looking to manipulate a set of strings in R. </p>
  
  <p>The data I have:</p>
  
  <pre><code>Data         Field
  Mark Twain   5
  </code></pre>
  
  <p>I want it to instead be:</p>
  
  <pre><code>Data        Field
  Twain Mark  5
  </code></pre>
  
  <p>My idea was to first split the string into two columns and then concatenate. But I'm wondering if there is an easier way.</p>
