HASPT: Heuristic Algorithms estimating SPT window.

Description

As used in function g.sib.det. Function is not intended for direct use by GGIR user.

Usage

HASPT(angle, params_sleep = NULL, ws3 = 5, 
      HASPT.algo="HDCZA", invalid, activity = NULL,
      marker = NULL, sibs = NULL)

Value

List with start and end times of the SPT window and the threshold as used.

Arguments

angle

Vector of epoch level estimates of angle

params_sleep

See GGIR

ws3

Number representing epoch length in seconds

HASPT.algo

See GGIR

invalid

Integer vector with per epoch an indicator of valid(=0) or invalid(=1) epoch.

activity

Numeric vector with magnitude of acceleration per epoch, only used when HASPT.algo is set to NotWorn. Acceleration metric used is specified by argument acc.metric elsewhere in GGIR.

marker

Optional, numeric vector with for each epoch an indication of whether the marker button was pressed (1) or not (0). Only used for Actiwatch-like devices such as MotionWare.

sibs

Numeric vector of classified sibs with HASIB, experimental not used at the moment.
