Helper functions for processing REDCap data in R.

‘REDCap’ (Research Electronic Data CAPture; is a web-enabled application for building and managing surveys and databases developed at Vanderbilt University.

Working with choose one questions

  • make_choose_one_table: print a janitor::tabyl style table with a variable label. This function lets you print one choice from a choose all that apply question.

Working with choose all that apply questions

REDCap exports the responses to a choose all that apply question into many similarly named questions. tidyREDCap helps summarize the responses with two functions:

  • make_binary_word: converts all the responses into a single descriptive “word”
  • make_choose_all_table: converts all the responses into a single summary table (coming soon)

Working with repeated measures

Projects that have repeated assessments with different questionnaires/instruments export with holes in the CSV. tidyREDCap will parse the export and create tables for any of the the questionnaires/instruments:

  • make_instrument: makes a tibble for an questionnaire/instrument (coming soon)
