title: Modify unplotted gList list
body: <p>If i have a gList that I have not plotted yet, can i modify the text in it.</p>
  
  <p>Example:</p>
  
  <pre><code>library('VennDiagram')
  temp &lt;- venn.diagram(list(A=0,B=0),euler.d=FALSE, scale=FALSE, filename=NULL)
  </code></pre>
  
  <p>Here temp is a unplotted gList, that I can plot by</p>
  
  <pre><code>grid.draw(temp)
  </code></pre>
  
  <p>But what If i wanted to modify the text objects (incl nubers) before plotting it but after creating the gList object. E.g can I change the values within the venn diagram after the gList have been created?</p>
  
  <p>I know I can do it with grid.edit() if I plot the venn diagram first, but that is not an option.</p>
  
  <p>in</p>
  
  <pre><code>str(temp)
  </code></pre>
  
  <p>it is the  ..$ label i want to change.</p>
  
  <p>In advance - thanks.</p>
