v0.7.1: Code quality and documentation

Improvements

• Refactored rcpp_aperture.cpp: parameterized helpers eliminate copy-paste across apertures
• Consolidated input validation: shared validate_aperture() / validate_resolution()
• Optimized is_pentagon(): direct quad coordinate lookup instead of lon/lat loop
• Stricter aperture parsing in hexify() with informative error
• Deduplicated theme_minimal() calls with .theme_clean() helper

Documentation

• Added "Why Hexagonal Grids?" section to README
• Added "Known Limitations" section to README

Tests

• New test-edge-cases.R with 32 tests: poles, antimeridian, dateline, roundtrip stability, pentagon invariants, neighbor symmetry

Full Changelog: v0.7.0...v0.7.1

v0.7.0: Fix ap7 encoding + neighbors + summarize

Hotfix

• Fixed aperture 7 cell encoding to use Class III substrate quantization.
• Updated max_cell_id() for aperture 7 bounding box.

New features

• get_neighbors() — k-ring neighbor lookup for all ISEA apertures + H3. Supports k > 1, distance output, vectorized input.
• hex_summarize() — cell-level aggregation with tidyeval. Groups by cell_id, returns centers/areas/counts.

hexify-0.6.5

Full Changelog: v0.6.4...v0.6.5

v0.6.4

Fix CRAN incoming check failures from v0.6.3 submission:

• Removed compiled object files (.o) from source tarball (caused installation ERROR on Debian)
• Wrapped plot_globe() examples in \donttest{} (was 608s on win-builder)
• Reworded vendored to included in DESCRIPTION (spelling flag)
• Strip debug symbols in Makevars to reduce installed library size

All v0.6.3 changes carried forward (antimeridian fix, globe projection fix, snprintf fix).

hexify 0.6.3

Antimeridian fix and auto-wrap dateline. See NEWS.md for details.

hexify 0.6.2

Native H3 backend with zero external dependencies.

• Vendored H3 v4.4.1 C source, replacing the h3o R package dependency
• H3 is now always available — no optional install, no Suggests
• Uses H3 experimental polygon fill for full spatial coverage in hexify()
• New native C++ bindings for all H3 operations

hexify 0.6.1

hexify 0.6.1

Polish H3 integration docs and UX:

• Warn when aperture is passed with type = "h3" (ignored parameter)
• Expanded H3 resolution guidance in hex_grid() documentation
• Extended H3 vignette resolution table to full range (0-15)
• Added h3_crosswalk() example to H3 vignette

v0.6.0: ISEA-H3 crosswalk and per-cell area

What's New

ISEA–H3 crosswalk and per-cell area

• New h3_crosswalk(): bidirectional mapping between ISEA and H3 cell IDs, with automatic resolution matching and per-cell area comparison
• New cell_area(): returns geodesic area (km²) for each cell — constant for ISEA (equal-area), location-dependent for H3, with session-scoped caching
• HexData $cell_area_km2, [["cell_area_km2"]], and as.data.frame() now return per-cell areas for H3 grids instead of the grid-wide average
• One-time session message when creating H3 grids to inform users that H3 cells are not exactly equal-area

Full Changelog: v0.5.0...v0.6.0

hexify 0.5.0

H3 grid support

• Added H3 (Uber) as a first-class grid type: hex_grid(resolution = 8, type = "h3")
• All core functions work with H3 grids: hexify(), cell_to_sf(), grid_rect(), grid_global(), grid_clip(), get_parent(), get_children()
• H3 support requires the h3o package (Suggests, not required for ISEA workflows)
• New hexify_compare_resolutions(type = "h3") for H3 resolution table
• dgearthstat() now accepts HexGridInfo objects directly
• New grid_type slot on HexGridInfo: "isea" (default) or "h3"
• HexData cell_id slot supports character (H3) and numeric (ISEA) cell IDs
• Backward compatible: all existing ISEA workflows unchanged

v0.3.7

Changes

• Removed slow spatial operation tests (grid_global, grid_rect, grid_clip)
• Reduced comprehensive roundtrip test combinations
• Test runtime now ~13 seconds (previously exceeded 10 min limit)

CRAN

This release addresses the test runtime issue from v0.3.6.
