check_metadata_fields_exist function

Check metadata fields exist for checkbox combination

Similar to check_fields_exist(), but instead of verifying fields that exist in the data tibble this seeks to verify their existence under the metadata tibble field_names.

check_metadata_fields_exist(metadata_tbl, cols, call = caller_env())

Arguments

• metadata_tbl: A metadata tibble from the supertibble generated by read_redcap().
• cols: Selected columns identified for combine_checkboxes() to be cross checked against metadata_tibble$field_name
• call: The calling environment to use in the error message
