Arguments

Ti	vector of Ti-concentrations (in ppm)
Si	vector of Si-concentrations (in ppm)
Sr	vector of Sr-concentrations (in ppm)
ternary	logical. If TRUE, produces a ternary diagram. Otherwise shows the results on a logratio plot.
pch	plot character. See ?par for details.
bg	fill colour for the plot character.
show.labels	logical. If TRUE, labels the polygonal decision fields with text strings.
short	use short labels when using the additional argument show.labels=TRUE.
xlim	x-axis limits
ylim	y-axis limits
...	additional arguments to the generic points function, may include the logical argument show.labels which labels the fields in the diagram.
Lu	vector of Lu-concentrations (in ppm)
Eu	vector of Eu-concentrations (in ppm)
V	vector of V-concentrations (in ppm)
Sc	vector of Sc-concentrations (in ppm)
Nb	vector of Nb-concentrations (in ppm)
Na	vector of Na-concentrations (in ppm)
Sm	vector of Sm-concentrations (in ppm)
Zr	vector of Zr-concentrations (in ppm)
Y	vector of Y-concentrations (in ppm)
major	a data frame with the following columns: SiO2, Al2O3, TiO2, CaO, MgO, MnO, K2O, Na2O (in wt%)

Value

a vector with tectonic affinities
