  <p>If I have two packages: A and B. Say there is function named <code>funfun</code> in A and there is function named  <code>funfun</code> in B too. When I load A and B, how do I use the first <code>funfun</code>? </p>
  
  <pre><code>require(A)
  require(B)
  </code></pre>
  
  <p>If I want to use <code>funfun</code> in A, how do I write this?</p>
