title: summary() function not printing correctly
body: <p>This might be a very lame question, but I cannot really figure out what's going. Normally if I called this function: </p>
  
  <pre><code>summary(VLTcog$per ~ VLTcog$Cognate)
  </code></pre>
  
  <p>The output that I got was:</p>
  
  <p>VLTcog$per    N=90</p>
  
  <p>+--------------+--+--+----------+<br>
  |              |  |N |VLTcog$per|<br>
  +--------------+--+--+----------+<br>
  |VLTcog$Cognate|C |48|74.42708  |<br>
  |              |NC|42|56.42857  |<br>
  +--------------+--+--+----------+<br>
  |Overall       |  |90|66.02778  |<br>
  +--------------+--+--+----------+   </p>
  
  <p>Now, if I do the same, the only output it gives me is:<br>
    Length   Class    Mode<br>
        3 formula    call<br>
  str of my data<br>
  str(VLTcog)<br>
  'data.frame':   90 obs. of  4 variables:<br>
   $ Item     : Factor w/ 90 levels "1 acquiesce",..: 86 16 30 62 28 53 26 83 51 65 ...<br>
   $ Cognate  : Factor w/ 2 levels "C","NC": 1 1 1 1 2 1 2 2 1 2 ...<br>
   $ Frequency: Factor w/ 5 levels "1","2","3","4",..: 1 1 1 1 1 1 1 1 1 1 ...<br>
   $ per      : num  100 67.5 95 82.5 87.5 67.5 95 40 87.5 87.5 ...  </p>
