geoGraph v2.0.1

  • Added ggplot2 support for gGraph, gData, and gPath objects via autoplot() methods and geom_ggraph(), geom_gdata(), and geom_gpath() layers.

  • closestNode now uses a faster KNN implementation for nearest neighbor searches by default. The legacy zone-expansion method is still available via method = “inArea”.

  • Functions that temporarily toggle sf settings now restore the prior state on exit.

  • Updated gPath2dist to now automatically return a vector or dist object based on the input type

  • Updated makeHexGrid to handle date line crossing gGraph objects

  • Updated isInArea to print a reproducible bounding box message

  • Added assignByRaster to assign raster cell values to graph nodes with customizable aggregation.

  • Added dijkstraBuffer to identify nodes within a specified shortest-path distance from an origin.

  • Added makeHexGrid for explicit hexagonal grid construction.

  • Deprecated extractFromLayer in favor of assignByPolygon and makeGrid in favor of makeSquareGrid.

  • Added documentation for the gPath class and basic subsetting methods for gGraph and gData objects

  • Added setGraph and setColors as well as updated functionality in getColors, getCosts, and setCosts

  • Removed getHistory method for gGraph objects and upgraded roxygen2 documentation from version 7.3.3 to 8.0.0

  • Added comprehensive test coverage for cost functions and updated documentation

  • Updated plot.gPath() and documentation for all dijkstra methods

  • Updated connectivityPlot() ensuring the color assignment matches the connected set

  • Fix incorrect handling of duplicate nodes in dijkstraBetween(), ensuring zero-distance paths are properly represented.

  • remove all use of deprecated packages (sp and maptools), and move to sf objects
