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.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
