microdatasus: Download and prepare DataSUS microdata

Provides a reproducible workflow for DataSUS microdata: fetch_datasus() discovers, downloads, and combines published DBC files; read_dbc() reads a local DBC file; and the process_*() functions convert system-specific fields into analysis-ready values and labels.

Details

Start with fetch_datasus() and then use the processor corresponding to the selected system, such as process_sim(), process_sinasc(), process_sih(), process_sia(), process_cnes(), or one of the process_sinan_*() functions. fetch_cadger() and fetch_sigtab() retrieve current auxiliary tables used by CNES and SIA processing.
