readAct(file, skip = 0)

readAct2(file, d.lig = NULL, skip = 0)

Arguments

file	the activity file to import.
skip	number of initial lines to skip
d.lig	dataframe of light data created with readLig

Details

Functions for importing activity data from BAS tags. The readAct function imports activity data from an early generation BAS tag while readAct2 imports activity data from later generation BAS tags that run length encode activity. If readAct2 is passed a dataframe constructed with readLig, it interpolates activity to the times at which light is recorded and returns a merged dataframe with both light and activity data.

Value

readAct returns a dataframe with columns

Valid	an indicator of whether the record is valid
Date	the date and time of the observation
Julian	date and time as Julian date
Activity	the recorded activity level
Temp	the recorded temperature

If readAct2 is passed a d.lig dataframe, it returns that dataframe with an appended column

Activity

otherwise it returns a dataframe with columns

Valid	an indicator of whether the record is valid
Date	the date and time of the observation
Julian	date and time as Julian date
