An example data frame with simulated plot errors for two traits in three environments. Environments 1 and 2 comprise two blocks, while Environment 3 comprises three blocks. The blocks are aligned in the column direction (side-by-side) and comprise 5 columns and 20 rows. The data frame was generated using the function field_trial_error with bivariate interpolation. The simulation is demonstrated in the vignette Simulation of plot errors and phenotypes in a plant breeding field trial.
