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
