ecreml R-package

The ecreml R-package consists of a series of functions to aid agricultural scientists and data analysts implement the statistical methodology described in Mumford et al. (2023), which incorporates environmental covariates (ECs) into a multi-environment trial (MET) analysis to better understand the environmental drivers contributing to the genotype $\times$ environment $\times$ management practice (G $\times$ E $\times$ M) interaction. The overall aim of the ecreml R-package is to make it as easy as possible for scientists to implement the statistical methodology for their own MET data.
