Fast Access to Brazilian Public Health Data from 'DATASUS' R package datasusr version 0.1.0 Provides fast, in-memory reading of 'DATASUS' 'DBC' files using native 'C' code, along with a catalog of public health data sources, 'FTP' file discovery, caching downloads, and a high-level datasus_fetch() function that lists, downloads, and reads files in a single call. Bundles the 'blast' decompressor from 'zlib' contrib/blast to decode 'PKWare DCL' compressed 'DBC' files and parses 'DBF' records directly for efficient import into tibbles. See the 'DATASUS' file transfer site <https://datasus.saude.gov.br> and Adler (2003) <https://github.com/madler/zlib/tree/master/contrib/blast> for details on the underlying data and compression format.
