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>.
