Add Connected Line Segments to a Ternary Plot

## Usage

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

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

# S4 method for 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.

graphics::lines()
