title: nltk tagged_words unexpected argument
body: <p>I am trying to learn NLTK by following instructions in a book. The code is:</p>
  
  <pre><code>from nltk.corpus import brown
  brown_news_tagged = brown.tagged_words(categories='news', tagsets='universal')
  </code></pre>
  
  <p>However, the error I get is: <code>tagged_words() got an unexpected keyword argument 'tagsets'</code></p>
