cnefetools 0.2.0

New functions

  • New tracts_to_polygon() for dasymetric interpolation from census tracts to user-supplied polygons, using CNEFE dwelling points as ancillary data.
  • New tracts_variables_ref reference table mapping cnefetools variable names to official IBGE census tract codes.

Major changes

  • hex_cnefe_counts() has been renamed to cnefe_counts(). The function now accepts user-supplied polygons via polygon_type = "user" in addition to H3 hexagons (polygon_type = "hex", default).
  • compute_lumi() gains support for user-supplied polygons via the same polygon_type parameter, and a new land-use mix indicator: ICE (Index of Concentration at Extremes).
  • tracts_to_h3() and tracts_to_polygon() gain five new interpolation variables related to race: race_branca, race_preta, race_parda, race_amarela and race_indigena.
  • read_cnefe(), cnefe_counts(), compute_lumi(), and tracts_to_h3() gain a year argument (default 2022) to prepare for future CNEFE editions.

Improvements

  • All user-facing functions now use the cli package (>= 3.6.0) for formatted console messages, replacing plain message() calls.
  • Improved diagnostic output in tracts_to_h3() and tracts_to_polygon() with two-stage reporting structure.
  • Census tract Parquet assets are now downloaded via piggyback from GitHub Releases, with on-demand caching.

Bug fixes

Documentation

  • Six pre-rendered pkgdown articles: reading CNEFE data, address counts, land-use mix indices, dasymetric interpolation, FAQ, and a DuckDB performance benchmark.
  • The package now features a new, more polished logo with improved visual quality.

cnefetools 0.1.1

cnefetools 0.1.0

  • New: tracts_to_h3() for dasymetric interpolation from tract aggregates to CNEFE dwelling points and H3 hexagons using DuckDB (spatial + h3).
  • Added UF-level census tract Parquet assets (WKB geometry) hosted on GitHub Releases and downloaded on-demand with caching.

cnefetools 0.0.6

  • Moves DBI and duckdb to Imports so the DuckDB backend works out of the box
  • Removes silent fallback to backend = "r" when backend = "duckdb" is requested
  • No changes to outputs; behavior is unchanged aside from dependency handling

cnefetools 0.0.5

  • Makes unit tests more reproducible and CI-friendly by removing dependencies on network access and local cache state (offline ZIP fixture and mocked downloads)
  • Improves robustness of read_cnefe(output = "sf") by handling missing coordinates before converting to sf
  • Updates COD_ESPECIE documentation and removes tidyselect deprecation warnings in tests and internals

cnefetools 0.0.4

  • Major speed-up for H3 assignment and hex-level aggregation via DuckDB + H3 extension (SQL), with runtimes dropping from minutes to seconds for large municipalities
  • Adds a configurable backend with backwards compatibility: backend = "duckdb" (default) or backend = "r" for hex_cnefe_counts() and compute_lumi()
  • Refactors internals to reuse cached ZIPs and consolidate common helpers, reducing repeated overhead and improving maintainability

cnefetools 0.0.3

  • More robust downloads with retry logic and increased timeout when needed
  • Avoids leaving partial or corrupted ZIP files in the cache
  • Automatically detects corrupted cached ZIPs and re-downloads before extraction

cnefetools 0.0.2

  • Add compute_lumi() to compute land-use mix indicators (EI, HHI, adapted HHI, BGBI) on H3 grids.
  • Extend README with examples for Fortaleza (code 2304400) and BGBI maps.

cnefetools 0.0.1

cnefetools 0.0.0.9000

  • Initial development version. Basic package infrastructure set up.
