title: fancyhdr in Latex - onesided book
body: <p>Here is my problem:</p>
  
  <p>Im writing my thesis using the book class. I want my thesis to be onesided (left and right margins of same size), but I would also like to use the fancyhdr package to give me chapter names in the pagehead of even pages and section names in the pagehead of odd pages.</p>
  
  <p>Trying to do so together with the "oneside" option gives me a warning when compiling saying that the [E] option is useless when the book is "onesided".</p>
  
  <p>Example code:</p>
  
  <pre><code>\documentclass[11pt,a4paper, oneside]{book}
  ...
  \fancyhf{} 
  \pagestyle{fancy}
    \headheight 20pt
    \fancyhead[LE]{\rightmark}
  </code></pre>
  
  <p>Any good ideas would be much appreciated!</p>
