title: How do I change a single value in a data.frame?
body: <p>Could anyone explain how to change a single cell in a <code>data.frame</code> to something else.
  Basically I just want to rename that one cell, not all cells which matches it.
  I can´t use the <code>edit()</code> command because it will screw up my script since im using the <code>data.frame</code> on several occasions.</p>
  
  <p>Thanks in advance</p>
