gmean {coda.base}

Geometric Mean

Description

Generic function for the (trimmed) geometric mean.

Usage

gmean(x, zero.rm = FALSE, trim = 0, na.rm = FALSE)

Arguments

x

A nonnegative vector.

zero.rm

a logical value indicating whether zero values should be stripped before the computation proceeds.

trim

the fraction (0 to 0.5) of observations to be trimmed from each end of x before the mean is computed. Values of trim outside that range are taken as the nearest endpoint.

na.rm

a logical value indicating whether NA values should be stripped before the computation proceeds.
