bouts.RIC: Merge bouts from RIC roughage intake files

In Animal: Analyze time-coded animal behavior data

Description

Merges single visits from roughage intake log file if the time difference between successive visits is less than specified time difference i.e merges multiple rows in the log file that are considered to be a single feeding bout to a single row.

Usage

bouts.RIC(data, bout.diff = 5)

Arguments

data	A data.frame read in with read.RIC, with clean=T option
bout.diff	The maximum time difference (in minutes) between visits in a single bout

Value

A data.frame with the values merged for individual bouts. All other objects are self.explanatory, but there are two that need further clarification

bout.duration	This is the duration in minutes of the merged bout i.e. begin-end for the bout.
intake.duration	This is the time in minutes that the cow has kept her head in the feeding trough during the bout. You may want to use this for calculating feeding speed (kg/min)

Note

The function is currently only implemented for merging feeding time and intake, thus protein, ash etc. are dropped from the resulting datafrane. The variables in the code are finnish and thus maybe difficult to follow. An english translation will (possibly) appear in the future.
