Calibrate Accelerometer Data using agcounts — acti

This uses the van Hees calibration method typically exposed through GGIR, implemented here via agcounts::agcalibrate().

Usage

acti_calibrate(
  data,
  verbose = TRUE,
  fill_zeroes = TRUE,
  round_after_calibration = TRUE,
  ...
)

Arguments

data: Either a GT3X file, AccData object, or data.frame with X/Y/Z and time
verbose: print diagnostic messages, higher number result in higher verbosity
fill_zeroes: Should actibase::acti_fill_zeros() be run before calculating the measures? This trims zero values from the beginning and the end of the time course using last observation carried forward behavior.
round_after_calibration: Should the data be rounded after calibration? Will round to 3 digits
...: Additional arguments to pass to agcounts::agcalibrate()

Value

A calibrated dataset with the same columns as the input data, but with the X/Y/Z values calibrated using the van Hees method.

Examples

# \donttest{
  res = acti_calibrate(data = actiread::acti_example_gt3x())
#> Detected gt3x file - reading in using acti_read_gt3x
#> Filling Zeros
#> Running agcounts::agcalibrate
#> Loading chunk: 1
#> 
#>  There is not enough data to perform the GGIR calibration method. Returning data as read by read.gt3x.
