tripoints: Barycentric plots

Description

Function to add points or lines to an existing (barycentric) plot.

Usage

tripoints(x, y = NULL, z = NULL, ...)
trilines(x, y = NULL, z = NULL, ...)

Arguments

x

Vector of fractions of first component OR 3-column matrix containing all three components (omitting y and z) OR 3-element vector (for all three components, omitting y and z).

y

(optional) vector of fractions of second component.

z

(optional) vector of fractions of third component.

Further graphical parameters (see points and par).

Examples

# NOT RUN {
triplot()  # empty plot 
tripoints(0.1, 0.2, 0.7)                        # a point 
tripoints(c(0.2, 0.6), c(0.3, 0.3), c(0.5, 0.1),
    pch = c(2, 6))                              # two points
trilines(c(0.1, 0.6), c(0.2, 0.3), c(0.7, 0.1), 
    col = "blue", lty = "dotted")               # a line 

trilines(centerlines(3))
