makeSleepDataMatrix: Make a sleep matrix based on the sleep onset and wake up time

In mMARCH.AC: Processing of Accelerometry Data with 'GGIR' in mMARCH

Make a sleep matrix based on the sleep onset and wake up time

Description

Make a sleep matrix (sleep=1 and wake=0) based on the sleep onset and wake up time for the purpose of calculating physical acitivy features during wake up time.

Usage

makeSleepDataMatrix(sleepFN, epochOut = 60, impute = TRUE, outputFN)

Arguments

sleepFN	charcter The input file name with path of sleep onset and wake up. By default, we use part4_nightsummary_sleep_full.csv under /results/QC folder from GGIR output.
epochOut	number Epoch size to which acceleration was averaged (seconds) in part 3. Defaut is 60 seconds.
impute	logical Specify if the missing sleep time was imputed based on the averge sleep onset and wake up time. Default is TRUE.
outputFN	character The output file name that the nonsleep matrix was wrote to. It includs filename, Date, daysleeper, sleeponset, wakeup, oldDate, sleepwindow, sleepimpute, MIN1, MIN2, ..., MIN1440 for the minutes level data when flag.epochOut=60 seconds.

Value

Sleep matrix and messages of sleep data.

duplicatedays	Duplicate days of sleep data if exists
sleepproblem	Invalid sleep data if exists
sleep matrix (0/1)	write the sleep matrix to a csv file specified by outputFN
