File S1 - Assessing Trait Covariation and Morphological Integration on Phylogenies Using Evolutionary Covariance Matrices

Computer Code for R. The function estimates the degree of phylogenetic morphological covariation between two sets of variables using partial least squares. The observed value is statistically assessed using phylogenetic permutation, where data for one block are permuted across the tips of the phylogeny, an estimate of the covariation between sets of variables, and compared to the observed value.
