Select efile fields by form scope
fields_in_scope.RdReturns the variable names present on a given return form, using the built-in field_concordance. Useful for restricting a panel to fields available on both the full 990 and the 990EZ, which avoids conflating a structural blank (field absent from the 990EZ) with a reported blank.
Usage
fields_in_scope(form = c("both", "990", "990EZ", "all"))
