The Aravo data set (Choler, 2005) consists of three main data tables. First, a count table collecting the abundance of 82 species of alpine plants in 75 sites in France (the rows correspond to the environments, and the column to species). We will denote this abundance table $$Y\in\mathbb{N}^{n\times p}$$. Second, a matrix containing 6 geographical and meteorological characteristics of the sites. Third, a matrix containing 8 species traits (height, spread, etc.). We denote $$R$$ the matrix of row covariates, and $$C$$ the matrix of column covariates.
