Drop columns from main that are also computed in loop

Before joining loop-derived columns into main, drop any column names main already shares with loop (e.g. from a prior run), except the two id columns used for the join.

Usage

drop_shared_loop_cols(main, loop, id_col_main, id_col_loop)

Arguments

main

A data frame (household-level)

loop

A data frame (individual-level, already summarized)

id_col_main

Column name for the unique identifier in main

id_col_loop

Column name for the unique identifier in loop

Value

main, with shared non-id columns dropped
