harmonic.mean {dae}

Calcuates the harmonic mean.

Description

A function to calcuate the harmonic mean of a set of nonzero numbers.

Usage

harmonic.mean(x)

Arguments

x

An object from whose elements the harmonic mean is to be computed.

Details

All the elements of x are tested as being less than daeTolerance, which is initially set to .Machine$double.eps ^ 0.5 (about 1.5E-08). The function set.daeTolerance can be used to change daeTolerance.

Value

A numeric. Returns Inf if x contains a value close to zero

Examples

y <- c(seq(0.1,1,0.2))
harmonic.mean(y)
