Transformation of Checkboxes with Branching Logic

This function inspects all the checkboxes in the study to determine if they have a branching logic. If a branching logic is present and its result is missing, the function will input a missing value into the checkbox. If checkbox_na is TRUE, the function will additionally input a missing value when the branching logic isn't satisfied, not just when it is missing. If a branching logic cannot be found or the logic cannot be transcribed due to the presence of smart variables, the variable is added to a list of reviewable variables that will be printed.

The function returns the dataset with the transformed checkboxes and a table summarizing the results.

Usage

transform_checkboxes(data, dic, event_form = NULL, checkbox_na = FALSE)

Arguments

data

Data frame containing data from REDCap.

dic

Data frame containing the dictionary read from REDCap.

event_form

Data frame containing the correspondence of each event with each form.

checkbox_na

Logical indicating if values of checkboxes with branching logic should be set to missing only when the branching logic is missing (FALSE), or also when the branching logic is not satisfied (TRUE). The default is FALSE.
