R package plot3logit

Package plot3logit is an implementation of the ternary plot for interpreting regression coefficients of trinomial regression models, as proposed in Santi, Dickson and Espa (2019). Ternary plots can be drawn using either ggtern package (based on ggplot2) or Ternary package (based on standard graphics). The package and its features are illustrated in Santi, Dickson, Espa and Giuliani (2022).
