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.
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.
- .record
A logical value. This indicates whether to record this code step. The default is TRUE. It should remain TRUE unless this function is used as a wrapper in other code.
