Package: PhysActBedRest Type: Package Title: Marks Periods of 'Bedrest' in Actigraph Accelerometer Data Version: 1.1 Date: 2020-9-4 Author: J. Dustin Tracy, Zhiyi Xu, Sari Acra, Kong Y. Chen, Maciej S. Buchowski, Thomas Donnelly Maintainer: J. Dustin Tracy Depends: R (>= 3.5.0), chron, stringr Imports: lubridate Description: Contains a function to categorize accelerometer readings collected in free-living (e.g., for 24 hours/day for 7 days), preprocessed and compressed as counts (unit-less value) in a specified time period termed epoch (e.g., 1 minute) as either bedrest (sleep) or active. The input is a matrix with a timestamp column and a column with number of counts per epoch. The output is the same dataframe with an additional column termed bedrest. In the bedrest column each line (epoch) contains a function-generated classification 'br' or 'a' denoting bedrest/sleep and activity, respectively. The package is designed to be used after wear/nonwear marking function in the 'PhysicalActivity' package. Version 1.1 adds preschool thresholds and corrects for possible errors in algorithm implementation.
