In vigicaen: 'VigiBase' Pharmacovigilance Database Toolbox

Example source tables for VigiBase and MedDRA

Description

Write some example tables as source csv/ascii/parquet files.

Usage

create_ex_meddra_asc(path)

create_ex_main_pq(path)

create_ex_sub_pq(path)

create_ex_main_csv(path)

create_ex_who_csv(path)

create_ex_sub_csv(path)

Arguments

path	Character string. A folder on your computer where the tables should be written.

Details

VigiBase tables and MedDRA tables are provided respectively as csv files and ascii files. The ⁠tb_*⁠ family turns them into parquet files. These ⁠create_example_*⁠ functions are only used to produce example source files to illustrate the ⁠tb_*⁠ family, and parquet files for the same purpose. Note that there is a little difference among main and sub tables, whether created in csv or parquet, as suspected duplicates moves from sub to main during tb_vigibase() process.

Value

A set of text/ascii files, as received by the Uppsala Monitoring Centre or MedDRA
