This function cleans the adaptive inventory responses stored as embedded data in Qualtrics
## S4 method for signature 'character' readQualtrics(catObj, responseID)
catObj |
Vector containing JSON character representations of the completed Cat objects from Qualtrics survey |
responseID |
Vector containing unique character identifiers for the respondents in the Qualtrics survey |
This function cleans the adaptive inventory responses contained in the Qualtrics survey results. Because different respondents recieve different adaptive inventories, their answers to the battery are not stored as usual as separate columns in the Data & Analysis tab in the Qualtrics toolbar. Rather, the respondents' answers to the adaptive battery are saved in the catObj embedded data object. To access the answers, click "Export & Import", and then "Export Data." In the window that appears, we recommend downloading the data as a .csv file. Then, feed this function the catObj column and the responseID column.
This function returns a data frame containing cleaned adaptive inventory responses.
