Add Connected Line Segments to a Ternary Plot

Description

Add Connected Line Segments to a Ternary Plot

Usage

ternary_lines(x, y, z, ...)

## S4 method for signature 'numeric,numeric,numeric'
ternary_lines(x, y, z, type = "l", ...)

## S4 method for signature 'ANY,missing,missing'
ternary_lines(x, type = "l", ...)

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 graphical parameters (see graphics::par()) may also be supplied as arguments, particularly, line type, lty, line width, lwd, color, col and for type = "b", pch. Also the line characteristics lend, ljoin and lmitre.
type	A character string indicating the type of plotting; actually any of the types as in graphics::plot.default().

Value

ternary_lines() is called it for its side-effects.

Examples

## Compositional data
coda <- data.frame(
  X = c(20, 60, 20, 20),
  Y = c(20, 20, 60, 40),
  Z = c(60, 20, 20, 40)
)

## Add lines
ternary_plot(NULL, panel.first = ternary_grid())
ternary_lines(coda, col = "red", lwd = 2)
