Encapsulates functions to streamline calls from R to the REDCap
    API.  REDCap (Research Electronic Data CAPture) is a web application for
    building and managing online surveys and databases developed at Vanderbilt
    University.  The Application Programming Interface (API) offers an avenue
    to access and modify data programmatically, improving the capacity for
    literate and reproducible programming.

Wraps dozens of 'REDCap' API endpoints into a standardized R6
    object.  Research Electronic Data Capture ('REDCap') is a survey and
    database web application software maintained by Vanderbilt University.
    It has a robust application programming interface (API) utilized by
    several R packages. 'REDCapSync' uses 'redcapAPI' and 'REDCapR'
    behind-the-scenes to retrieve all metadata, data, and log details for
    a project. To minimize unnecessary server calls, the interim 'REDCap'
    log is analyzed and used to only update necessary records.
    Furthermore, the user can define custom datasets that save to a
    directory. Those datasets continue to refresh when projects are
    synced.  Having a secure, standardized, API-efficient,
    project-agnostic R object for 'REDCap' projects, streamlines
    downstream use in scripts, functions, and shiny applications.

Convert 'REDCap' exports into tidy tables for easy handling of 'REDCap' repeat instruments and event arms.

'REDUCE' is a portable general-purpose computer algebra system supporting scalar, vector, matrix and tensor algebra, symbolic differential and integral calculus, arbitrary precision numerical calculations and output in 'LaTeX' format. 'REDUCE' is based on 'Lisp' and is available on the two dialects 'Portable Standard Lisp' ('PSL') and 'Codemist Standard Lisp' ('CSL'). The 'redcas' package provides an interface for executing arbitrary 'REDUCE' code interactively from 'R', returning output as character vectors. 'R' code and 'REDUCE' code can be interspersed. It also provides a specialized function for calling the 'REDUCE' feature for solving systems of equations, returning the output as an 'R' object designed for the purpose. A further specialized function uses 'REDUCE' features to generate 'LaTeX' output and post-processes this for direct use in 'LaTeX' documents, e.g. using 'Sweave'.
