Details

Each factor type variable in REDCap is given the attributes redcapLabels and redcapLevels. With these attached to the vector, switching between the coded and labelled values can be done with ease. This may be helpful when the coded value has importance, such as 0/1 for death, or if a yes is worth 6 points (instead of 1).
