Supplemental functions and data for 'OpenIntro' resources, which 
    includes open-source textbooks and resources for introductory statistics 
    (<https://www.openintro.org/>). The package contains datasets used in our 
    open-source textbooks along with custom plotting functions for reproducing 
    book figures. Note that many functions and examples include color 
    transparency; some plotting elements may not show up properly (or at all) 
    when run in some versions of Windows operating system.

Tools for the analysis of land use and cover (LUC) time series. It 
    includes support for loading spatiotemporal raster data and synthesized 
    spatial plotting. Several LUC change (LUCC) metrics in regular or irregular 
    time intervals can be extracted and visualized through one- and multistep 
    sankey and chord diagrams. A complete intensity analysis according to 
    Aldwaik and Pontius (2012) <doi:10.1016/j.landurbplan.2012.02.010> is 
    implemented, including tools for the generation of standardized multilevel 
    output graphics.

A client for the Open-Meteo API that retrieves Open-Meteo
    weather data in a tidy format. No API key is required. The API specification
    is located at <https://open-meteo.com/en/docs>.

Provides a client for the open-source monitoring and alerting
  toolkit, 'Prometheus', that emits metrics in the 'OpenMetrics' format. Allows
  users to automatically instrument 'Plumber' and 'Shiny' applications, collect
  standard process metrics, as well as define custom counter, gauge, and
  histogram metrics of their own.

'Mindat' ('mindat.org') is one of the world's most widely used databases of mineral species and their distribution. Many scientists in mineralogy, geochemistry, petrology, and other Earth and planetary disciplines have been using the 'Mindat' data. Still, an open data service and the machine interface have never been fully established. To meet the overwhelming data needs, the 'Mindat' team has built an API (<https://api.mindat.org/schema/redoc/>) for data access.'OpenMindat' R package provides valuable functions to bridge the data highway, connecting users' data requirements to the 'Mindat' API server and assist with retrieval and initial processing to improve efficiency further and lower the barrier of data query and access to scientists. 'OpenMindat' provides friendly and extensible data retrieval functions, including the subjects of geomaterials (e.g., rocks, minerals, synonyms, variety, mixture, and commodity), localities, and the IMA (International Mineralogical Association)-approved mineral list. 'OpenMindat' R package will accelerate the process of data-intensive studies in mineral informatics and lead to more scientific discoveries.
