associations_drop_na: Drop any NA associations.
Description
This function takes an associations S4 object and removes any association
identifiers that might have been NA. This ensures that there is always a
non-NA association_id
value in all tables. This is important as the
association_id
is the primary key.
Usage
associations_drop_na(s4_associations)
Value
An object of class associations.
