computeDuration: computeDuration

In esmprep: Data Preparation During and After the Use of the Experience Sampling Methodology (ESM)

Description

computeDuration computes the duration between when an ESM questionnaire was started and when it was finished.

Usage

computeDuration(esDf, RELEVANTVN_ES = NULL)

Arguments

esDf	a data.frame. A single ESM dataset. It must contain the 2 columns that hold the date-time object for when an ESM questionnaire was started and finished, respectively.
RELEVANTVN_ES	a list. This list is generated by function setES and it is extended once either by function genDateTime or by function splitDateTime.

Value

esDf with the additional column DUR (short for duration).
