esmprep (version 0.2.0)

genKey: genKey

Description

genKey generates a unique number for each ESM questionnaire.

Usage

genKey(dfList)

Arguments

dfList

a list. Each element of the list must be a data.frame. Each data.frame is a separate raw ESM dataset/an ESM questionnaire version. If there is just one ESM version the list therefore contains one data.frame.

Value

esDf with the additional column KEY, i.e. a unique integer for each data row.

Details

The unique number for each ESM questionnaire can be seen as an identifier prior to the assignment of the participants who filled out the questionnaires. Such an identifier is valuable in controlling a large amount of rows of data.
