Calculate Step Counts via stepcount — acti_calculate_stepcount • actimetrics

Use the stepcount package to estimate steps from raw accelerometer data and summarize them to minute-level epochs (as opposed to 10s default)

Usage

acti_calculate_stepcount(data, sample_rate = NULL, ...)

Arguments

data: A data.frame, AccData object, or GT3X file with X, Y, Z, and time
sample_rate: Sample rate in Hz. If omitted, it is taken from the input object when available.
...: Additional arguments passed to stepcount::stepcount()

Value

A tibble with minute-level time, steps, and walking columns.

Examples

if (FALSE) { # \dontrun{
  reticulate::py_require("stepcount==3.11.0", python_version = "3.10", action = "add")
  sc = reticulate::import("stepcount")
  data = actiread::acti_read_gt3x(actiread::acti_example_gt3x())
  steps = acti_calculate_stepcount(data, sample_rate = 100)
  steps = acti_calculate_stepcount(data, model_type = "rf")
} # }
