traits_drop_na: Drop any NA traits.
Description
This function takes a traits S4 object and removes any EFO trait identifiers
that might have been NA. This ensures that there is always a non-NA
efo_id
value in all tables. This is important as the efo_id
is the primary key.
Usage
traits_drop_na(s4_traits)
Value
An object of class traits.
