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.

Partitions the phenotypic variance of a plastic trait, studied through its reaction norm. The variance partition distinguishes between the variance arising from the average shape of the reaction norms (V_Plas) and the (additive) genetic variance . The latter is itself separated into an environment-blind component (V_G/V_A) and the component arising from plasticity (V_GxE/V_AxE). The package also provides a way to further partition V_Plas into aspects (slope/curvature) of the shape of the average reaction norm (pi-decomposition) and partition V_Add (gamma-decomposition) and V_AxE (iota-decomposition) into the impact of genetic variation in the reaction norm parameters.

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.
