\title{Calculate the geometric mean}
\usage{
geomean(x, na.rm = FALSE)
}
\arguments{
\item{x}{Vector of numbers}

\item{na.rm}{Should NA values be omitted?}
}
\value{
The geometric mean
}
\description{
Based on some posts in a thread on Stackoverflow
\url{http://stackoverflow.com/questions/2602583/geometric-mean-is-there-a-built-in}
This function returns NA if NA values are present and na.rm = FALSE
(default). If negative values are present, it gives an error message.
If at least one element of the vector is 0, it returns 0.
