landscapemetrics - landscapemetrics 2.1.0

  • Improvements
    • Many performance improvements. Most visible are in
      calculate_lsm (all metrics: more than 5 times faster with 70% less memory
      allocation for augusta_nlcd; larger increases were found for smaller data)
      and window_lsm (a single metric: more than 6 times faster for augusta_nlcd;
      larger increases were found for smaller data)
    • Some performance improvements are related to the new "extras" mechanism, in which several objects
      are precalculated in calculate_lsm
    • Creates an internal extras_df object that lists which extras are needed by
      each metric
    • Replaces the use of tibble::tibble() with tibble::new_tibble(list()) in most functions.
      This change is partially responsible for improvements of the window_lsm speed
    • Replaces raster_to_points with get_points in several places.
      The get_points function is based on the column and row numbers multiplied by
      the resolution, not actual coordinates.
    • Replaces table with (faster) tabulate in lsm_p_core
  • New functions
    • Adds a few internal helper functions and documents them, including prepare_extras,
      get_area_patches, get_class_patches, get_complexity, get_enn_patch,
      get_points, and get_perimeter_patch
  • Bugfixes
    • Fixes window_lsm behaviour for situations with NAs values and non-square windows
  • Various
    • Fixes several typos and improves documentation in many places
    • Uses object references in most rcpp functions
