Included as an example for teaching about functions. As well as for a discussion of how to estimate central tendencies.
The harmonic mean(s)
Included as a simple demonstration of how to write a function
x <- seq(1,5) x2 <- x^2 x2[2] <- NA X <- data.frame(x,x2) harmonic.mean(x) harmonic.mean(x2) harmonic.mean(X) harmonic.mean(X,FALSE)
