title: Combinations of multiple vectors in R
body: <p>I'm not sure if permutations is the correct word for this. I want to given a set of n vectors (i.e. <code>[1,2]</code>,<code>[3,4]</code> and <code>[2,3]</code>) permute them all and get an output of</p>
  
  <pre><code>[1,3,2],[1,3,3],[1,4,2],[1,4,3],[2,3,2] etc.
  </code></pre>
  
  <p>Is there an operation in R that will do this?</p>
