title: R readHTMLTable() function error
body: <p>I'm running into a problem when trying to use the <code>readHTMLTable</code> function in the R package XML.    When running</p>
  
  <pre><code>library(XML)
  baseurl &lt;- "http://www.pro-football-reference.com/teams/"
  team &lt;- "nwe"
  year &lt;- 2011
  theurl &lt;- paste(baseurl,team,"/",year,".htm",sep="")
  
  readurl &lt;- getURL(theurl)
  readtable &lt;- readHTMLTable(readurl)
  </code></pre>
  
  <p>I get the error message:</p>
  
  <pre><code>Error in names(ans) = header : 
  'names' attribute [27] must be the same length as the vector [21]
  </code></pre>
  
  <p>I'm running 64 bit R 2.15.1 through R Studio 0.96.330.  It seems there are several other questions that have been asked about the readHTMLTable() function, but none addressed this specific question.  Does anyone know what's going on?</p>
