Sample of highly irregular wearable data

Description

A dataset collected with a wearable device that has a somewhat irregular recording pattern. Overall, the data are recorded every 15 seconds. Every tenth or so measurement takes 16 seconds, every hundredths 17 seconds, every thousandths 18 seconds, and so on. This makes the dataset a prime example for handling and dealing with irregular data.

Usage

sample.data.irregular

Format

sample.data.irregular A tibble with 11,422 rows and 13 columns:

Id

A character vector indicating the participant (only P1).

Datetime

POSIXct Datetime

lux

numeric Illuminance. Unit is lux.

kelvin

numeric correlated colour temperature (CCT). Unit is Kelvin.

rgbR

numeric red sensor channel output. Unit is W/m2/nm.

rgbG

numeric green sensor channel output. Unit is W/m2/nm.

rgbB

numeric blue sensor channel output. Unit is W/m2/nm.

rgbIR

numeric infrared sensor channel output. Unit is W/m2/nm.

movement

numeric indicator for movement (intensity) of the device. Movement is given in discrete counts correlating to the number of instances the accelerometer records instances greater than 0.1875g per 15s sampling interval.

MEDI

melanopic EDI measurement data. Unit is lux.

R.

Unknown, but likely direct or derived output from the red sensor channel

G.

Unknown, but likely direct or derived output from the green sensor channel

B.

Unknown, but likely direct or derived output from the blue sensor channel
