stepmetrics - Calculate Step and Cadence Metrics from Wearable Data
Provides functions to calculate step- and cadence-based
metrics from timestamped accelerometer and wearable device
data. Supports CSV and AGD files from 'ActiGraph' devices, CSV
files from 'Fitbit' devices, and step counts derived with R
package 'GGIR' <https://github.com/wadpac/GGIR>, with automatic
handling of epoch lengths from 1 to 60 seconds. Metrics include
total steps, cadence peaks, minutes and steps in predefined
cadence bands, and time and steps in moderate-to-vigorous
physical activity (MVPA). Methods and thresholds are informed
by the literature, e.g., Tudor-Locke and Rowe (2012)
<doi:10.2165/11599170-000000000-00000>, Barreira et al. (2012)
<doi:10.1249/MSS.0b013e318254f2a3>, and Tudor-Locke et al.
(2018) <doi:10.1136/bjsports-2017-097628>. The package record
is also available on Zenodo (2023)
<doi:10.5281/zenodo.7858094>.
