Description

Computes and draws the closed geometric mean of the set of points specified.

ternary_mean(x, y, z, ...)

## S4 method for signature 'numeric,numeric,numeric'
ternary_mean(x, y, z, ...)

## S4 method for signature 'ANY,missing,missing'
ternary_mean(x, y, z, ...)

Arguments

x, y, z	A numeric vector giving the x, y and z ternary coordinates of a set of points. If y and z are missing, an attempt is made to interpret x in a suitable way (see grDevices::xyz.coords()).
...	Further arguments to be passed to graphics::points().
