Changelog

Source: NEWS.md

priogridR 0.6.0

New functionality

• Added pg_neighbor_table() for reusable queen, rook, distance-band, and k-nearest-neighbor definitions.
• Added pg_weights() for binary and inverse-distance spatial weights with optional row standardization.
• Added pg_spatial_lag() for cell-level and cell-period spatial lags without leakage across temporal groups.
• Added pg_distance() and pg_nearest() for cell-centre distance and nearest neighbor workflows.
• Added pg_buffer_summary() for cell-level summaries within explicitly defined distance buffers.

Documentation and quality

• Added a spatial-context vignette with end-to-end examples.
• Added tests for contiguity, antimeridian behavior, candidate restrictions, distance calculations, weight construction, temporal isolation, missing values, buffer summaries, and input validation.
• Linked the README license badge to the bundled license to avoid dependence on an external license page during URL checks.

priogridR 0.5.1

Documentation

• Added executable reference examples for the point, vector, and table converters, project paths, and result writing.
• Added guarded interactive examples for raster and NetCDF conversion, whose execution requires a configured priogrid working directory.
• Added focused vignettes for grid identifiers and neighborhoods, and for structured results, output, project paths, and visualization.
• Ensured that every public function has a reference example and that every public function group has focused vignette coverage.

priogridR 0.5.0

New functionality

• Added pg_id_from_coords() and pg_coords_from_id() for converting between coordinates and configured PRIO-GRID cell identifiers.
• Added pg_geometry() for creating polygon or centre-point geometries.
• Added pg_validate_data() for checking identifiers, panel keys, duplicates, and completeness.
• Added pg_complete_panel() for explicitly completing cells and cell-time combinations.
• Added pg_join() for relationship-checked joins that guard against accidental many-to-many expansion.
• Added pg_plot() for quickly mapping cell-level variables.

Improvements

• Added a grid-foundations vignette and comprehensive tests for the new API.
• Extended the function inventory and pkgdown reference organization.

priogridR 0.4.1

Improvements

• Made the raster and NetCDF vignettes portable across local, GitHub Actions, and CRAN build environments by avoiding changes to persistent priogrid configuration during rendering.

priogridR 0.4.0

Breaking changes

• Standardized the public API on the pg_ prefix and snake case.
• Renamed create_pg_indices() to pg_create_indices().
• Renamed pgneighbors() to pg_neighbors().
• Renamed pgtheme() to pg_theme().
• Renamed write_pg_result() to pg_write_result().

New functionality

• Added converters for raster, vector, point-event, NetCDF, and geographically indexed tabular data.
• Added configurable temporal aggregation through PRIO-GRID configuration objects.
• Added structured conversion results and output helpers.
• Added tests, vignettes, continuous integration, and publication scaffolding.
• Added focused workflow vignettes for every pg_from_*() converter.

Improvements

• Corrected polar behavior in neighborhood lookup while retaining optional longitudinal wrapping.
• Added validation for grid dimensions and function arguments.
• Added metric/geodesic handling for polygon areas and line lengths.
• Made raster and NetCDF vignettes self-contained by using temporary PRIO-GRID working directories during rendering.
• Improved documentation and package organization for eventual CRAN and JOSS submission.
