amadeus 2.0.0

CRAN release: 2026-05-21

Major updates to code base - breaking changes have been minmized but please report if 1.3.x versions are not working as expected

  • Refactored code base to improve maintainability and utilize modern R API designs and best practices
  • The only breaking change that should affect previous version users is the process_tri() and calculate_tri() series.

Spatial and Temporal summarization with .by and .by_time parameters

  • Added .by and .by_time parameters to all calculate_*() functions for consistent spatial and temporal summarization options across all datasets
  • The default behavior of calculate_*() functions remains unchanged - i.e., no summarization, returning extracted or summarized values at the temporal resolution of the data - but users can now specify .by for spatial grouping (e.g., by HUC, county, state) and .by_time for temporal grouping (e.g., by year, month) to obtain summarized covariate values directly from the calculation step

‘frac’ option for categorical variable covariate calculation

  • hms, koppen, and ecoregion datasets now have optional fraction covariate calculation that returns the fraction of each category in the radius buffer.

drop options for categorical variable covariate calculation

  • hms, koppen, and ecoregion datasets now have optional drop parameter that will drop or exclude categories that don’t have any coverage in the radius buffer for a given point, which can help reduce the number of columns returned when many categories are possible but only a few are present in the area around the point.

Detailed vignettes for each dataset including available variables, spatial and temporal resolution, and example use cases

  • workflow vignette for each dataset with detailed information on available variables, spatial and temporal resolution, and example use cases for each dataset

nhdplusTools use

Additional MODIS products

  • Added support for additional MODIS products with a focus on the burned area and active fire products

Finalize data API that were previously in development

  • Added or completed the functonality for PRISM, EDGAR, CropScape, and HUC datasets

Use of GitHub Copilot for code generation and refactoring

  • Used GitHub Copilot for help with code generation and refactoring across the code base, including function development, documentation, and unit tests; all generated code was reviewed and edited by the development team to ensure accuracy and consistency with package standards

Drought Index Support

Migrate from wget/curl to httr2

  • Completed migration of all download_* functions from httr/wget/curl command-line calls to httr2 for all network requests
  • Deprecated download parameter (use default download = TRUE) and remove_command parameter across all download functions; both now emit informative warnings and are ignored
  • Added hash parameter to all download_* functions for optional MD5 file integrity verification via download_hash() (using system md5sum)
  • Added unzip and remove_zip parameters to download_prism() for post-download archive handling
  • Added download_run_method() internal helper for unified httr2-based file retrieval with progress reporting, retry logic, and rate limiting
  • Improved check_url_status() for general-purpose URL validation
  • Expanded unit test coverage with mock-based tests for all download functions covering deprecation warnings, hash paths, and file-exists branches
  • Added full variable reference to download_narr() documentation, listing all 88 available NARR variable abbreviations with descriptions grouped by category (monolevel, pressure level, subsurface); resolves #194
  • Added download_narr() tests covering every variable abbreviation across all three variable categories
  • Fixed download_data() dispatch to include "edgar" so download_edgar() is reachable via the wrapper function

amadeus 1.3.2

  • Fixed deprecated file paths for NLCD, MODIS, and Ecoregions datasets
  • Removed the certificate verification from ecoregion download which is not needed anymore
  • For NASA datasets MODIS, VIIRS, and Geos-CF, added additional tags in the wget scripts to prevent API throttling
  • httr upgraded to httr2
  • Modified internal URL status check function for general use
  • Added the news function to display the NEWS.md content within R pkgdown site
  • Improved the reporting in the GitHub Actions workflows

amadeus 1.2

  • future and future.apply dependencies were removed
  • calculate_modis_par() is renamed to calculate_modis()

amadeus 1.1

  • calc_*() functions are renamed to calculate_*() per naming convention of other function family in the package

amadeus 1.0

  • First CRAN release (v.1.0.0)
