title: Can't load 'survival' in R version 3
body: <p>I have tried a lot in stackoverflow for this question, such as <code>update.package</code>, install 'codetools', and some tips in stackoverflow- How should I deal with “package 'xxx' is not available” warning?
  but it doesn't work.
  The package seems to be installed, but can't be loaded- </p>
  
  <pre><code>library(survival) 
  ## error:package ‘survival’ was built before R 3.0.0: please re-install it
  </code></pre>
