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.

We provide an R interface to 'OpenML.org' which is an online machine learning platform where researchers can access open data, download and upload data sets, share their machine learning tasks and experiments and organize them online to work and collaborate with other researchers. 
    The R interface allows to query for data sets with specific properties, and allows the downloading and uploading of data sets, tasks, flows and runs.
