‘Ternary’ is an R package that allows the creation of ternary plots (a.k.a. ternary graphs / simplex plots / Gibbs triangles / de Finetti diagrams) and Holdridge life zone diagrams using the familiar functions of the default ‘graphics’ package.

For simple use cases, generate ternary plots using the point-and-click Shiny app:

install.packages('Ternary')
Ternary::TernaryApp()

For greater control over your plots, use the R command line; usage instructions are available for Ternary plots (with an introductory vignette for R beginners), and for Holdridge plots.

Install the development version from GitHub with devtools::install_github("ms609/Ternary", args="--recursive"). (Requires git to be installed and added to your PATH system environment variable.)

Please let me know of any feature requests or bugs by opening an issue on GitHub.
