title: R indentation in Google's R Style Guide
body: <p>I am reading <a href="http://google-styleguide.googlecode.com/svn/trunk/Rguide.xml" rel="nofollow">Google's R Style Guide</a>. It said:</p>
  
  <blockquote>
    <p>When indenting your code, use two spaces. Never use tabs or mix tabs and spaces.</p>
  </blockquote>
  
  <p>I use R Studio to program and feel it is very convenient and beautiful to use tabs. Other programming languages also use tabs for indentation.</p>
  
  <p>I don't know why Google's R Style Guide does not recommend use tabs but two blanks.</p>
