In FJValverde/entropies: Plotting ternary entropy diagrams for joint distributions, contingency matrices, etc

Environment construction

library(ggtern)
library(entropy)  # To work out the appropriate coordinates.
library(caret)    # To build the classifiers.
library(mlbench)  # Many databases for ML tasks

Datasets available

The inventory of databases to be explored:

# the inventory of databases you can access
#library(datasets)
name <- c("Ionosphere", "iris", "Glass") # 
classVar <- c(35, 5, 10)   # ordinal of the class attribute
className <- c("Class","Species", "Type")  # Name of class attribute
K <- c(2, 3, 7)  # No. of classes
datasets <- data.frame(name,classVar,className,K)

# To select a dataset by name
evalDataset <- function(dsName){
    dsName <- as.character(dsName)
    switch(dsName,
