In pvermees/provenance: Statistical Toolbox for Sedimentary Provenance Analysis

Ternary confidence ellipse

Description

plot a 100(1-\alpha)\% confidence region around the data or around its mean.

Usage

ternary.ellipse(x, ...)

## Default S3 method:
ternary.ellipse(x, alpha = 0.05, population = TRUE, ...)

## S3 method for class 'compositional'
ternary.ellipse(x, alpha = 0.05, population = TRUE, ...)

## S3 method for class 'counts'
ternary.ellipse(x, alpha = 0.05, population = TRUE, ...)

Arguments

x	an object of class ternary
...	optional formatting arguments
alpha	cutoff level for the confidence ellipse
population	show the standard deviation of the entire population or the standard error of the mean?

Examples

data(Namib)
tern <- ternary(Namib$Major,'CaO','Na2O','K2O')
plot(tern)
ternary.ellipse(tern)
