fct_drop

fct_drop.data.frame

fct_drop.factor

This extends [forcats::fct_drop()] to natively work across a data.frame and
replaces [base::droplevels()].

Casting metadata for REDCap database creation and handling of
castellated data using repeated instruments and longitudinal projects in
'REDCap'. Keeps a focused data export approach, by allowing to only export
required data from the database. Also for casting new REDCap databases based
on datasets from other sources.
Originally forked from the R part of 'REDCapRITS' by Paul Egeler.

'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>).
