tb_who: Create main WHO tables

Description

Transform Vigibase WHO .txt files to .parquet files

WHODrug is delivered as zipped text files folder, that you should transform to a more efficient format. Parquet format from arrow has many advantages: It can work with out-of-memory data, which makes it possible to process tables on a computer with not-so-much RAM. It is also lightweighted and standard across different languages. The function also creates variables in each table. See tb_vigibase() for some running examples, and try ?mp_ or ?thg_ for more details. Use dt_parquet() to load the tables afterward.

tb_who(path_who, force = FALSE)
