The geometric mean is the nth root of n products or e to the mean log of x. Useful for describing non-normal, i.e., geometric distributions.
geometric.mean(x,na.rm=TRUE)geometric mean(s) of x or x.df.
a vector or data.frame
remove NA values before processing

Useful for teaching how to write functions, also useful for showing the different ways of estimating central tendency.

x <- seq(1,5)
x2 <- x^2
x2[2] <- NA
X <- data.frame(x,x2)
geometric.mean(x)
geometric.mean(x2)
geometric.mean(X)
geometric.mean(X,na.rm=FALSE)
