Introduction | Installation | Recommended Workflow | 1. Inspect metadata without decompressing | 2. Read directly into a data frame (small to medium files) | 3. Working with large files that exceed Excel's row limit | 4. Stream to CSV on disk (large files, low RAM usage) | 5. Convert to Parquet (recommended for Big Data) | 6. Decompress to DBF (interoperability) | 7. Parallel conversion | 8. Convert a directory | Practical Epidemiology Examples | Working with dates | Decoding the age field (NU_IDADE_N) | Handling missing values | Frequency tables and case counts | Combining multiple DBC files (full year from monthly files) | Fast analytical queries on Parquet files with DuckDB | Export to formatted XLSX (Excel) | Performance Comparison | DBC Format — How Decompression Works | Thread Safety

dbcturbo: High-Performance Streaming Reader for 'DATASUS' DBC Files
A modern, memory-efficient R package for reading and converting DBC files produced by the Brazilian Ministry of Health's 'DATASUS' system. DBC files are DBF databases compressed with the 'PKWare' implode algorithm. Unlike 'read.dbc', this package processes files in streaming mode, never loading the full dataset into RAM. It can export directly to CSV or DBF and provides R helpers for in-memory reading and Parquet conversion.
