cnefetools 0.2.3

• Fixed missing hexagons at the edges of the H3 grid. h3jsr::polygon_to_cells() only returns hexagons whose centroid falls inside the municipality boundary, so border hexagons that overlap the boundary without their center being inside were silently excluded. build_h3_grid() now adds those hexagons by checking the immediate neighbors of the grid against the municipality boundary (#62).

• cnefe_counts() and compute_lumi() now expose a cache parameter (default TRUE), consistent with tracts_to_h3() and tracts_to_polygon() (#58).

• New clear_cache_muni() function to delete cached CNEFE ZIP files from the user cache directory, with optional filtering by municipality code (#59).

• New clear_cache_tracts() function to delete cached census tract Parquet files, with optional filtering by state (UF) code (#59).

cnefetools 0.2.2

• Resubmission to CRAN following package removal on 2026-02-26.
• No functional changes. Retains the skip_on_cran() fix from v0.2.1 for the DuckDB spatial extension segfault on r-devel-linux-x86_64-fedora-clang.

cnefetools 0.2.1

• Adds skip_on_cran() to test-tracts_to_h3.R to prevent a segfault on r-devel-linux-x86_64-fedora-clang caused by an ABI mismatch between the clang-compiled DuckDB binary and GCC-built spatial extension (duckdb/duckdb-r#1107).

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

• Removed inconsistencies in spatial join operations in cnefe_counts(), compute_lumi(), and tracts_to_polygon() with DuckDB.
• Fixed community extension loading failures in DuckDB.
• Fixed temporary file path bugs in tracts_to_h3() and tracts_to_polygon().
• Fixed invalid geometry handling when user-supplied polygons.

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

• Adds Balance Index (BAL), bal to the compute_lumi() function.

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.
