The IntCal20 radiocarbon calibration curves (Reimer et al. 2020 <doi:10.1017/RDC.2020.68>) are provided as a data package, together with previous IntCal curves (IntCal13, IntCal09, IntCal04, IntCal98), other curves (e.g., NOTCal04 [van der Plicht et al. 2004], Arnold & Libby 1951, Stuiver & Suess 1966, Pearson & Stuiver 1986) and postbomb curves. Also provided are functions to copy the curves into memory, and to read, query and plot the data underlying the IntCal20 curves.

This tool can be used to build binary interval trees using real number inputs. 
    The tree supports queries of intervals overlapping a single number or an interval (start, end). 
    Intervals with same bounds but different names are treated as distinct intervals. 
    Insertion of intervals is also allowed. Deletion of intervals is not implemented at this point.

Allows the user to view an image in full screen when clicking on it in 'RMarkdown' documents and 'shiny' applications. 
  The package relies on the 'JavaScript' library 'intense-images'. See <https://tholman.com/intense-images/> for more information.

A wrapper for the 'Intro.js' library (For more info: <https://introjs.com/>). 
  This package makes it easy to include step-by-step introductions, and clickable hints in a 'Shiny' 
  application. It supports both static introductions in the UI, and programmatic introductions from 
  the server-side.

Streamlined data import and export by making assumptions that
    the user is probably willing to make: 'import()' and 'export()' determine
    the data format from the file extension, reasonable defaults are used for
    data import and export, web-based import is natively supported (including
    from SSL/HTTPS), compressed files can be read directly, and fast import
    packages are used where appropriate. An additional convenience function,
    'convert()', provides a simple method for converting between file types.
