‘ggtern’ is an R package, an extension to ggplot2, for the plotting of ternary diagrams. Ternary diagrams are Baycentric plots w/ three variables – additional information on the semantics of ternary diagrams can be found HERE. With the exception of the work by Sean Mulcahy and Darren Wilkinson, there are very few resources on the internet where ggplot2 has been used as a platform for rendering ternary diagrams – ggtern attempts to bridge this gap!
