50Sm - Ti/50 - V (Vermeesch 2006)

Description

QDA-based diagram for geotectonic discrimination of igneous rocks of Vermeesch 2006.

Usage

TiSmV(Sm = WR[, "Sm", drop = FALSE], Ti = WR[, "Ti", drop = FALSE], 
    V = WR[, "V", drop = FALSE], pch = labels[, "Symbol"], col = labels[, "Colour"], 
    cex = labels[, "Size"], ternary = TRUE, xlim = NULL, ylim = NULL, show.labels = TRUE, 
    short = TRUE, ...)

Arguments

Sm

vector of Sm concentrations (ppm)

Ti

vector of Ti concentrations (ppm)

V

vector of V concentrations (ppm)

pch

plotting symbol - see ?par for details

col

plotting symbol colour

cex

plotting symbol size

ternary

logical. If TRUE, produces a ternary diagram. Otherwise shows the results on a logratio plot

xlim

x-axis limits

ylim

y-axis limits

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

...

additional arguments to the generic points function, may include the logical argument show.labels which labels the fields in the diagram.

Details

This plot comes from the GeoplotR collection available online at https://isoplotr.es.ucl.ac.uk/geoplotr.
