Multivariate Analysis of Ecological Data with ade4

It is implemented around the mathematical concept of the duality diagram, and provides a unified framework for multivariate analysis.  The authors offer a detailed presentation of the theoretical framework of the duality diagram and also of its application to real-world ecological problems.  These two goals may seem contradictory, as they concern two separate groups of s
