sample.accel R Documentation
Sample Zio Accelerometer Data
Description
A sample accelerometer data file for one individual over the course of wear (~ 14 days). This data is used to illustrate processing of activity and posture summaries.
Usage
sample.accel
Format
A data frame with four columns including
- time
the associated date-time of the accelerometer measurement. The dates and timezones have been changed from their original versions to remove any participant identifying information.
- x, y, z
accelerometer measurements along three orthoganol axes in gravitational units.
Source
Data in this sample were collected by the Multicenter AIDS Cohort Study (MACS).
Dates were changed.
The MACS website is located at http://aidscohortstudy.org/.
