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
