Financial contributions, where possible, are very much appreciated. Please contribute push/pull requests via BitBucket repository. To install the development / working version, use the devtools package: devtools::install_git('') Contributing Install the latest release on CRAN, install just like any other R package: install.packages('ggtern') Of course, the above book by Wilkinson outlines the theory, whilst Hadley Wickhams ggplot2 implementation is where much of the magic happens, and, an ideal base-platform for ggtern. Ggtern is a package that is based on (extends) the very popular ggplot2, which is an implementation of Wilkinsons The Grammar of Graphics, and, makes provision for a highly methodical construction process for the development of meaningful (graphical) data representations. It is possible to represent a coordinate system having three (3) degrees of freedom, in 2D space, since the third dimention is linear and depends only on the other two. Ternary diagrams are used frequently in a number of disciplines to graph compositional features for mixtures of three different elements or compounds. Ggtern is a package that extends the functionality of ggplot2, giving the capability to plot ternary diagrams for (subset of) the ggplot2 proto geometries. An extension to ggplot2, for the creation of ternary diagrams.
