plot.ternary: Plot a ternary diagram

In provenance: Statistical Toolbox for Sedimentary Provenance Analysis

Description

Plots triplets of compositional data on a ternary diagram

Usage

## S3 method for class 'ternary'
plot(x, type = "empty", pch = NA, pos = NULL,
  labels = names(x), showpath = FALSE, bg = NA, col = "cornflowerblue",
  ellipse = FALSE, alpha = 0.05, population = TRUE, ...)

Arguments

x	an object of class ternary, or a three-column data frame or matrix
type	adds annotations to the ternary diagram, one of either empty, QFL.descriptive, QFL.folk or QFL.dickinson
pch	plot character, see ?par for details (may be a vector)
pos	position of the sample labels relative to the plot symbols if pch != NA
labels	vector of strings to be added to the plot symbols
showpath	if x has class SRDcorrected, and showpath==TRUE, the intermediate values of the SRD correction will be plotted on the ternary diagram as well as the final composition
bg	background colour for the plot symbols (may be a vector)
col	colour to be used for the background lines (if applicable)
ellipse	plot a logistic 100(1-alpha)\% confidence region around the data (population=TRUE) or around its mean (population=FALSE)?
alpha	the confidence level (0≤qα≤q1) for the confidence region.
population	draw the confidence region around the entire population, or around its mean?
...	optional arguments to the generic points function
