This function forces values the variables in
.var to take constant values within combinations of the variables in
fixed_force() will return a data frame with consistency enforced.
fixed_force(.df, .var = NULL, .within = NULL, .resolve = mode_order, .flag = NA)
Data frame, pibble, or tibble.

Function capable of being passed to
String indicating the name of a new variable that flags any observations altered by
Inconsistencies will be resolved by the function
.resolve. Or, set
'drop' (or any string, really) to drop all cases with inconsistency.
