      <h2>Description</h2>

      <p>Based on some posts in a thread on Stackoverflow
<a href = 'http://stackoverflow.com/questions/2602583/geometric-mean-is-there-a-built-in'>http://stackoverflow.com/questions/2602583/geometric-mean-is-there-a-built-in</a>
This function checks for negative values, removes NA values per default and
returns 0 if at least one element of the vector is 0.</p>
