R: Weighted harmonic mean

a_hmean

R Documentation

Weighted harmonic mean

Weighted harmonic mean of a vector. NA are skipped by default.

a_hmean(x, w = NULL)

`x`	A numeric vector of positive values.
`w`	A vector of weights, which should have length equal to `length(x)`. Weights are relative and will be re-scaled to sum to 1. If `w` is not specified, defaults to equal weights.

This function replaces the now-defunct harMean() from COINr < v1.0.

Weighted harmonic mean, as a numeric value.

# a vector of values
x <- 1:10
# a vector of weights
w <- runif(10)
# weighted harmonic mean
