REDCapCAST

REDCap Castellated data handling when using repeated instruments.

This package is a fork of SpectrumHealthResearch/REDCapRITS. The REDCapRITS represents great and extensive work to handle castellated REDCap data in different programming languages. This fork is purely minded on R usage and includes a few implementations of the main REDCap_split function.

The main goal for this project was to allow for a "minimal data" approach by allowing to filter records, instruments and variables in the export to only download data needed. I think this approach is desireable for handling sensitive, clinical data. No similar functionality is available from similar tools (like REDCapR or REDCapTidieR). Please refer to REDCap-Tools for other great tools.

Use and immprovements

This package is primarily relevant for working with longitudinal projects and/or projects using repeated instruments. Here is just a short descirption of the main functions:

• REDcap_split(): Works largely as the original REDCapRITS::REDCap_split(). It takes a REDCap dataset and metadata (data dictionary) to split the data set into a list of dataframes of instruments.

• read_redcap_tables(): wraps the use of REDCapR::redcap_read() with REDCap_split() to ease the export of REDCap data.

• redcap_wider(): pivots each data frame with repeated instruments to a wide format utilizing the tidyr::pivot_wider() from the tidyverse.

Compared to the original REDCapRITS, all matching functions are improved to accept column naming of REDCap data from manual download or API export.
