Pattern matching, extraction, replacement and other string
  processing operations using Google's RE2 <https://github.com/google/re2>
  regular-expression engine. Consistent interface (similar to 'stringr').
  RE2 uses finite-automata based techniques, and offers a
  fast and safe alternative to backtracking regular-expression engines
  like those used in 'stringr', 'stringi' and other PCRE implementations.

Tools to help with 'shiny' reactivity. The 'react' object offers
    an alternative way to call reactive expressions to better identify them
    in the server code.

Interactive data tables for R, based on the 'React Table'
    JavaScript library. Provides an HTML widget that can be used in 'R Markdown'
    or 'Quarto' documents, 'Shiny' applications, or viewed from an R console.

Enhanced functionality for 'reactable' in 'shiny' applications, offering interactive and dynamic data table capabilities with ease.
    With 'reactable.extras', easily integrate a range of functions and components to enrich your 'shiny' apps and facilitate user-friendly data exploration.

Provides various features to streamline and enhance the styling of interactive 
    reactable tables with easy-to-use and highly-customizable functions and themes. 
    Apply conditional formatting to cells with data bars, color scales, color tiles,
    and icon sets. Utilize custom table themes inspired by popular websites such 
    and bootstrap themes. Apply sparkline line & bar charts 
    (note this feature requires the 'dataui' package which can be downloaded from
    <https://github.com/timelyportfolio/dataui>).
    Increase the portability and reproducibility of reactable tables by embedding images 
    from the web directly into cells. Save the final table output as a static image or 
    interactive file.

Provides a checkbox group input for usage in a 'Shiny'
    application. The checkbox group has a head checkbox allowing to check
    or uncheck all the checkboxes in the group. The checkboxes are
    customizable.
