‘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")This requires git to be installed and added to your PATH system environment variable. You may also require the ‘curl’ R package.
