g.sib.det: sustiained inactivty bouts detection

Description

Detects sustiained inactivty bouts. Function not intended for direct use by package user

Usage

g.sib.det(M, IMP, I, twd=c(-12,12), anglethreshold = 5, 
              timethreshold = c(5,10), acc.metric = "ENMO",
              desiredtz="", constrain2range=TRUE, 
              myfun=c(), sensor.location = "wrist", HASPT.algo="HDCZA",
              HASIB.algo = "vanHees2015",
              Sadeh_axis = "Y", longitudinal_axis=c(), HASPT.ignore.invalid=FALSE)

Arguments

M

Object produced by g.getmeta

IMP

Object produced by g.impute

I

Object produced by g.inspectfile

twd

Vector of length 2, indicating the time window to consider as hours relative to midnight.

anglethreshold

See g.part3

timethreshold

See g.part3

acc.metric

Which one of the metrics do you want to consider to analyze L5. The metric of interest need to be calculated in M (see g.part1)

desiredtz

See g.part3

constrain2range

See g.part3

myfun

External function object to be applied to raw data. See details applyExtFunction.

sensor.location

See g.part3

HASPT.algo

Character to indicate what heuristic algorithm to use for detecting the SPT window, see HASPT

HASIB.algo

Character to indicate what heuristic algorithm to use for detecting the SIB window, see HASIB

Sadeh_axis

Character to indicate which axis to use for the Sadeh1994 algorithm, and other algortihms that related on count-based Actigraphy such as Galland2012.

longitudinal_axis

Integer, to indicate which axis is the longitudinal axis. If not provided function will estimate longitudinal axis. Only used when sensor.location="hip" or HASPT.algo="HorAngle".

HASPT.ignore.invalid

See HASPT

Value

• output = Dataframe for every epoch a classification

• detection.failed = Boolean whether detection failed

• L5list = L5 for every day (defined from noon to noon)
