bout_summary {triact}

Output of Triact$summarize_bouts()

Description

Output of Triact$summarize_bouts(). The information contained in the output table depends on the analyses you added to the Triact object using the $add_activity(), $add_lying(), and $add_side() methods.

The asterisk (*) in the column names below stands for one of 'L1', 'L2', 'AdjL1', and 'AdjL2', indicating type of norm (L1, L2) and 'adjustment' of activity values to zero during lying, i.e. lying considered inactive by definition. DBA is the abbreviation for the dynamic body acceleration. See Simmler & Brouwers (2023).

id Cow id

bout_nr Sequential numbering of the bouts per cow id

startTime Start time of the bout

endTime End time of the bout

duration Duration of the bout. Units: As specified via the duration_units argument.

lying TRUE for lying bouts, FALSE for standing bouts

side "L" for left lying side, "R" for right lying side (NA for standing bouts)

mean*DBA Mean of the DBA-based proxy for physical activity. Units: g

mean*Jerk Mean of the Jerk-based proxy for physical activity. Units: g s^{-1}
