title: Packages loaded into memory
body: <p>I'm want to loop through all packages I have currently loaded in memory i.e. those I have "libraried", and export them to parallel clusters using </p>
  
  <pre><code>clusterEvalQ(cl, library(*pkagename*))
  </code></pre>
  
  <p>Is there a way of detecting which packages are loaded into memory and creating a list of them?</p>
