Data matrices and R scripts for the paper “Quantifying environmental adaptation of metabolic pathways in metagenomics”

With respect to your your metagenomics paper which appeared in PNAS (, I was wondering if it is still possible to access the entire (1) environmental features vs. geographic sites and (2) metabolic features vs. geographic sites matricesas used in the paper? Also, is it still possible to access the R scripts that were used in this work?
