chopin 0.9

• mirai based par_* functions for parallelization

chopin 0.8

• Bumped version from 0.7.8 to 0.8.0: improving package coverage
• README.md: two mermaid plots are pre-generated as png files
• Internal clip_*() functions and vect_validate() are removed
• par_map_args() is renamed to par_convert_f()
• init.R: one-line initialization for bbox class detection (cf. https://github.com/r-spatial/sf/issues/2448)

chopin 0.7

• .check_package refactoring: no library() call is required
• Internal function .check_par_spatraster is added to main par_* functions
• Internal preprocessing "dot-functions" -- universally usable functions are plain S3, whereas others that are class-specific were implemented in S4
• Added
  • CITATION.cff
  • par_*: argument pad_y to enable applying padded extent to x or y (e.g., y in raster-vector overlay and x otherwise)
• Updated
  • README.Rmd: split the combined one into two mermaid figures -> MD rebuilt, removed date of last update
  • par_*: argument name change from debug to .debug
• Dropped
  • Custom backend for future and mirai; rolling back to future.apply
  • any_class_args, is_within_ref, par_fallback, check_dist_incorrect
  • par_grid argument: grids_input_ids
  • Data: SRTM (TIFF replaces RDS)
• Data preprocessing parts are separated into internal functions
• Name change
  • check_subject to .check_vector
  • reproject_b2r to reproject_to_raster
  • vect_valid_repair to vect_validate
• targets-friendly helper function: par_split_list
  • Vignette for par_split_list
• par_* family naming hierarchy: par_make_* to par_pad_*
  • Plain gridding (par_make_grid) and clustering (par_make_balanced) functions are internal
• Main par_* runners (par_grid, par_hierarchy, par_multirasters) are kept
• extract_at is redesigned as a S4 method
• All messaging is managed by cli package
• Added zzz.R for startup message
• summarize_aw gets generic argument names x and y
• mirai backend is introduced
• Internal functions are not exported
• Type check function check_subject is added. This function is internal.
• vapply argument FUN.VALUE fixed

chopin 0.6

• Fixed: grid_target_id in par_grid accepts numeric or character input to filter grids
• par_fallback is returning error_message field with actual error messages
• collapse package is added to Imports (i.e., rowbind function is used in place of dplyr::bind_rows)
• Tests were fixed following refactoring/updating par_* functions
• chopin processing functions now support file path input with extents in par_grid
• Fixed: Missing argument passing in par_pad_grid with mode = "grid_advanced"
• Vignette update: v01
• Fixed: align input-output classes in par_merge_grid
• Improved: grid_advanced mode supports the maximum of merged unit grids
• Added the balanced number mode of splitting input points (par_pad_balanced; thanks to comments of Dr. Michael Fessler)
• Added function of the balanced mode for par_grid (par_group_grid)
• All internal sapply is changed to vapply
• Added a diagram for guiding users' choice for par_* functions for parallelization considering raster/vector data situations
• litr R Markdown file is moved to the archive

chopin 0.5

• par_grid unifies the classes of grid inputs
• par_cut_coords: a supplementary function effectively operating with par_def_q for mode = "grid_quantile" in par_pad_grid. X- and Y-coordinates (of centroids for polygon inputs) are split into quantile groups to balance the number of features in each grid; does not account for geometric complexity (i.e., number of vertices)
• Padded grid generation in par_pad_grid is done only by terra::buffer
• extract_at* functions get max_cells, which is passed to exactextractr::exact_extract for speedup in expense of memory pressure
• Added a new vignette on the demonstration of climate/weather data extraction

chopin 0.4

• surf argument in extract_at*() accepts file paths
• Raster cropping is now optional

chopin 0.3

• Dropped rast_short
• Added examples
• README.md is replaced by README.Rmd
• Documentation is clarified about the second argument in ... in par_* functions
