How to find the harmonic mean of a vector in R

Question

What R function should I use to compute the harmonic mean of a vector of numbers?

Answer 1

You can use the harmonic.mean() function of the psych library to calculate the harmonic mean. If the package psych is not installed, you can install it by running command install.packages("psych").

> library(psych)
> x <- seq(1,5)
> x
[1] 1 2 3 4 5
> harmonic.mean(x)
[1] 2.189781
