ag_feature_calc: Custom function to compute features of raw accelerometer...

In robmarcotte/MOCAfunctions:

Custom function to compute features of raw accelerometer data. Can be applied to fixed- or variable-windows (epochs vs sojourns, respectively).

Description

Custom function to compute features of raw accelerometer data. Can be applied to fixed- or variable-windows (epochs vs sojourns, respectively).

Usage

ag_feature_calc(
  ag_data_raw_wrist,
  participant,
  samp_freq = 80,
  window = 15,
  soj_colname = NA,
  seconds_colname = NA,
  inactive_threshold = 0.1
)

Arguments

ag_data_raw_wrist	Raw accelerometer data containing AxisX, AxisY, AxisZ, and VM data columns
participant	Character string for participant ID
samp_freq	Sampling frequency of the raw accelerometer data. Defaults to 80 Hz
window	Epoch window (in seconds). Can be either a fixed number or 'sojourn' character string. If 'sojourn', a column of sojourn indices is expected to be present in the data.
soj_colname	Character string for column name containing the sojourn indices
seconds_colname	Character string for column name containing the duration of a given sojourn Library dependencies: tidyverse, lubridate, data.table
