SleepEstEachDay: Daily sleep estimate

Description

Obtain sleep data from accelerometer data

Usage

SleepEstEachDay(
  datain,
  f = 1,
  id = NA,
  Y_name = "max_count",
  T = 0.4,
  nonwear_detect = FALSE,
  wear_mins = 120,
  S = 3,
  NoPA_cut = 0.7,
  sleep_mins = 20,
  wake_mins = 180,
  nap_mins = 20,
  UseDiary = FALSE,
  diary_data = c(),
  CommonBedTime = "22:00:00",
  CommonWakeTime = "8:00:00",
  tz = "GMT"
)

Value

list containing a data frame of summary sleep data

Arguments

datain

input accelerometry dataset, must be tibble, data frame, etc.

f

cost function indicator

id

subject id

Y_name

column name of the activity count data to be used in analysis, for example max count of x, y, z axes or vector magnitude

T

threshold percentile of activity level

nonwear_detect

flag indicating use of nonwear detection algorithm, default is FALSE

wear_mins

threshold number of minutes to define wear segment

S

number of segments per hour

NoPA_cut

percent of 0 counts to define NoPA segments

sleep_mins

threshold number of minutes to define sleep segment

wake_mins

threshold number of minutes to define wake segment

nap_mins

threshold number of minutes to define nap segment

UseDiary

flag indicating if diary data to be used, default is FALSE

diary_data

diary data, must be a data frame

CommonBedTime

in-bed time if no diary data, default is "22:00:00"

CommonWakeTime

out-bed time if no diary data, default is "8:00:00"

tz

timezone, default is GMT

Examples

AccelData <-
ChangeTimeVar(AccelData, col_idx = 1, format = "%m/%d/%Y %H:%M")

SleepEstEachDay(AccelData, Y_name = "VM")

data("AccelData")

AccelData <-
