Compositional data analysis are tools to analyse data that are part of a whole. This package includes basic fonctions from the "compositions" R package: closing data to a simplex summing to 100%, plot ternary diagrams, scale and center data, compositional data transformation using additive, centered and isometric techniques and plotting basic coda-dendrograms.
