Package: stepmetrics Type: Package Title: Calculate Step and Cadence Metrics from Wearable Data Version: 1.1.0 Authors@R: c( person("Jairo H", "Migueles", email = "jairo@jhmigueles.com", role = c("aut", "cre")), person("Elroy J", "Aguiar", role = "fnd", comment = "Funding and data support"), person("University of Alabama", "", role = "fnd")) Description: 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' , 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) , Barreira et al. (2012) , and Tudor-Locke et al. (2018) . The package record is also available on Zenodo (2023) .
