Adding Points to Ternary Diagrams

Description

Use ternarypoints to add points to a ternary diagram generated using the ternaryplot function in the vcd library. Use ternary diagrams to plot expected values for multinomial choice models with three categories in the dependent variable.

Usage

ternarypoints(object, pch = 19, col = "blue", ...)

Arguments

object

The input object must be a matrix with three columns.

pch

The selected type of point. By default, pch = 19, solid disks.

col
