Chapter Chapter 3 in Multivariate Analysis of Ecological Data with ade4, 2018, pp 29-51 from Springer

Abstract: Abstract This chapter explains the structure of the dudi (S3) class, which is the core of the ade4 package. All the multivariate data analysis methods available in ade4 can be described in the framework of the duality diagram and an object of class dudi is a translation of this mathematical structure in R. In this chapter, we explain what is an object of class dudi and which functions are used to generate and handle it. We detail all its elements, how to use it to analyse data tables, and how to export its elements to use them outside R.
