logical, whether to use this mapping in CALIBERcodelists. We use maps if no_map is FALSE and choice_list is 0 or 1.

Note

For CALIBER users, the tables are included in the CALIBERlookups package.

If there is no CALIBER_GEM table in the global environment, CALIBERcodelists functions will create one containing a small sample of terms. This is used for testing the examples.
