Define the possible allocation of treatments to units

This function adds the edges between variable nodes to specify the mapping of units to treatment. This function does not actually assign specific treatment levels onto actual units.

allot_trts(design, ...)

Arguments

...	One-sided or two-sided formula. If the input is a one-sided formula then the whole treatment is applied to the specified unit.
.data	An edbl_graph object.

Examples

start_design() %>%
  set_units(block = 10,
            plot = nested_in(block, 3)) %>%
  set_trts(treat = c("A", "B", "C"),
           pest = c("a", "b")) %>%
  allot_trts(treat ~ plot,
                pest ~ block)
#> An edibble design
#> ├─block (10 levels)
#> │ └─plot (30 levels)
#> ├─treat (3 levels)
#> └─pest (2 levels)
#> Allotment:

#> • treat ~ plot
