R script works with fertSyn+Sevietta water data file and the USDA plants traits database. It requires the USDA plot checklist, and the synonym function script to aid in matching species between the two datasets. It removes sites and experiements we are not using, and generates several intermediate data files: 1. species X trait table 2. Species X site X treatment X year relative abundances and response ratios. UPDATED to work with new KNZ plots too.
