Fixed an issue where add_country(), restrict_to_country() and restrict_to_GHA() did not recognize Somaliland as part of Somalia.
Fixed an issue where requiring minimal coverage in upscale_regular_lon_lat() did not work correctly, if the data table contained grid cells with missing values
Changed the default behavior of CHIRPS upscaling to only include gridcells with at least 50% coverage. Fixed a warning that was always printed at the end of download_chirps_monthly()
Renamed ggplot_dt_gha_map() and ggplot_dt_shf() into gha_plot().
Fixed a bug where ggplot_dt() and gha_plot() crashed when the provided data table has a column named "country" as its first non-dimvar column.
Added package-level documentation.
Deprecated the old functions ggplot_dt_gha_map(), ggplot_dt_shf(), and restrict_to_confer_region().
Added a NEWS.md file to track changes to the package.
A high resolution map of the Greater Horn of Africa is now included as part of the package. This is the standard map used during GHACOFs at ICPAC. This map is used by the new plotting functions ggplot_dt_gha_map (which else pretty much works as ggplot_dt) and tercile_plot.
A new function set_spatial_grid has been added. The function allows to store a grid-attribute with a data table. This attribute contains information about the spatial grid of a data table, e.g. whether the grid is regular or complete. The new function grid_info prints this information out for a data table.
upscale_regular_lon_lat now allows to specify a required fraction of coverage and excludes all coarse grid cells that have less than this required coverage.
Several small bugs have been fixed.
