Example data for calculating bouts of moderate-to-vigorous physical activity

Description

A dataset containing accelerometer data and predicted energy expenditure in metabolic equivalents (METs) that can be used to classify moderate-to-vigorous physical activity in continuous bouts.

Usage

ex_data

Format

A data frame with 10080 rows and 12 variables:

FileID: character. Name of the file originating the data
Date: character giving the date ("%m/%d/%Y")
Time: character giving the time ("%H:%M:%S")
DateTime: full timestamp (%Y-%m-%d %H:%M:%S) given as character
dayofyear: numeric day of the year (i.e., julian date)
minofday: numeric minute of the day (i.e., 0 for midnight and 1439 for 11:59)
Axis1: activity counts for the device's first axis
Axis2: activity counts for the device's second axis
Axis3: activity counts for the device's third axis
Steps: number of steps taken
Vector.Magnitude: vector magnitude (Euclidian norm) of the activity counts from the three axes
METs: predicted energy expenditure, in metabolic equivalents
