    Harris, et al. (2019) <doi:10.1016/j.jbi.2019.103208>) is
    a web application for building and managing online surveys and databases
    developed at Vanderbilt University.  The API allows users to access data
    and project meta data (such as the data dictionary) from the web
    programmatically. The 'redcapAPI' package facilitates the process of
    accessing data with options to prepare an analysis-ready data set
    consistent with the definitions in a database's data dictionary.

    'REDCap' database casting and handling of castellated data when using 
    repeated instruments and longitudinal projects. Keeps a focused data export 
    approach, by allowing to only export required data from the database.
    'REDCap' (Research Electronic Data Capture) is a secure, web-based software
    platform designed to support data capture for research studies, providing
    1) an intuitive interface for validated data capture; 2) audit trails for
    tracking data manipulation and export procedures; 3) automated export
    procedures for seamless data downloads to common statistical packages; and
    4) procedures for data integration and interoperability with external 
    sources (Harris et al (2009) <doi:10.1016/j.jbi.2008.08.010>; 
    Harris et al (2019) <doi:10.1016/j.jbi.2019.103208>).

REDCap Data Management - REDCapDM is an R package that allows users to manage data exported directly from REDCap or using an API connection. This package includes several functions designed for pre-processing data, generating reports of queries such as outliers or missing values, and following up on the identified queries. 'REDCap' (Research Electronic Data CAPture; <https://projectredcap.org>) is a web application developed at Vanderbilt University, designed for creating and managing online surveys and databases and the REDCap API is an interface that allows external applications to connect to REDCap remotely, and is used to programmatically retrieve or modify project data or settings within REDCap, such as importing or exporting data.
