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

geomean(c(1, 3, 9))
geomean(c(1, 3, NA, 9))
