Programmatic interface to the Web Service methods provided by
    the USA National 'Phenology' Network (<https://usanpn.org/>), which
    includes data on various life history events that occur at specific
    times.

Apply sensitivity analysis for offline policy evaluation, as
    implemented in Jung et al. (2017) <arXiv:1702.04690> based
    on Rosenbaum and Rubin (1983) <http://www.jstor.org/stable/2345524>.

Utility functions to retrieve data from the UK National River
    Flow Archive (<https://nrfa.ceh.ac.uk/>, terms and conditions:
    <https://nrfa.ceh.ac.uk/help/costs-terms-and-conditions>). The package
    contains R wrappers to the UK NRFA data temporary-API. There are
    functions to retrieve stations falling in a bounding box, to generate
    a map and extracting time series and general information. The package
    is fully described in Vitolo et al (2016) "rnrfa: An R package to
    Retrieve, Filter and Visualize Data from the UK National River Flow
    Archive"
    <https://journal.r-project.org/archive/2016/RJ-2016-036/RJ-2016-036.pdf>.

Routines to interact with the Numerai Machine Learning Tournament
  API <https://numer.ai>. The functionality includes the ability to automatically download the
  current tournament data, submit predictions, and to get information for your
  user.

Creates JavaScript charts with the 'nvd3' library. So far only the multibar chart, the horizontal multibar chart, the line chart and the line chart with focus are available.

Provides an R interface to the ROCEEH Out of Africa Database (ROAD) (<https://www.roceeh.uni-tuebingen.de/roadweb/smarty_road_simple_search.php>), a comprehensive resource for archaeological, anthropological, paleoenvironmental and geographic data from Africa and Eurasia dating from 3,000,000 to 20,000 years BP. The package allows users to retrieve data from the online database at different levels of detail and customize search requests. Functions return `data frame` objects compatible with other R packages used in prehistoric and paleoenvironmental science, supporting reproducible workflows as an input provider.
