title: Cannot use msn.marginal {sn} in R
body: <p>I have try many ways, but i still cannot use <code>msn.marginal</code> for my research.
  When I try to install the package <code>sn</code> in the latest R software (Ri386 3.2.0), <code>msn.marginal</code> is not in there</p>
  
  <pre><code>msn.marginal
  </code></pre>
  
  <blockquote>
    <p>Error: object 'msn.marginal' not found</p>
  </blockquote>
  
  <p>I also tried to install the package of <code>sn</code> version 0.4-18, but I still cannot use <code>msn.marginal</code></p>
  
  <p>So, I tried to install the <code>sn</code> package of version 0.4-14, but this is what I got </p>
