title: Installing R package tm in amazon EMR
body: <p>I couldnt install the package <code>tm</code> in EMR. It seems some version issue. First I installed teh latest version tm 0.6. It is not supported by R 2.15.2 which is in the EMR. Then I try to install version tm 0.5-8.1. Now I'm getting the following error.</p>
  
  <p><code>dependency 'slam' is not available for package 'tm'</code></p>
  
  <p>Can you suggest me the correct package/packages to install <code>tm</code> in EMR Amason?</p>
