title: Python 2.7 - Rpy2 Cox Proprotional Hazards Model
body: <p>I am using <code>Python 2.7</code> on <code>Mac OSX Lion</code> and will be installing <code>rpy2</code> to use <code>Cox Proportional Hazards Model</code></p>
  
  <p>I was just wondering: has anybody used <code>rpy2</code> to do Cox Proportional Hazards before.  I was reading some of the documentation on the <code>rpy2</code> package and it mostly talks about creating <code>dataframes</code> and such, as opposed to stating how various functions can be run.  So, how would I go about calling this function and then specifying the dependent <code>time variable</code>, as well as the <code>censoring</code> variable (designated by a binary <code>1</code> value)?</p>
  
  <p>The R package for Mac also recommends that the computer not be connected to the internet when it is in use.  Why is that?</p>
