expand_conditions: Expand assignment conditions
In DeclareDesign/ddoldversion: Declare and Diagnose Research Designs

Internal helper to eagerly build assignment conditions for potential outcomes.

1 2	expand_conditions(formula, conditions = c(0, 1), assignment_variables = "Z", data, level = NULL, label = NULL)

`conditions`	the conditions
`assignment_variables`	the name of assignment variables, if conditions is not already named.

If conditions is a data.frame, it is returned unchanged

Otherwise, if conditions is a list, it is passed to expand.grid for expansion to a data.frame

Otherwise, if condition is something else, box it in a list with assignment_variables for names, and pass that to expand.grid.

a data.frame of potential outcome conditions
