"pairwise", "trt.vs.ctrl", "eff"; or (2) an emmeans-style contrast By default, all pairwise comparisons are generated if by is an unordered factor and ordered comparisons are made if by is ordered. You can also use emmeans_comparison() to generate unique combination of levels of draw_indices). log4j provides you configuration file based level setting which sets you free from changing the source code when you want to change the debugging level.
