A seven-day example of minute-level accelerometer data. It contains a timestamp, counts for each accelerometer axis, vector-magnitude counts, log-transformed counts, and a wear indicator. The data are suitable for the examples in acti_plot_time(), acti_plot_day(), and acti_plot_heatmap().

Usage

acti_minute_data

Format

A tibble with 10,080 rows and 7 variables:

time

Timestamp of the minute, as POSIXct.

axis1, axis2, axis3

Axis-specific activity counts.

counts

Vector-magnitude activity counts.

counts_log10

Log10-transformed vector-magnitude counts.

wear

Whether the minute was classified as wear time.

Source

The Figshare collection from Chadwell (2019) doi:10.6084/m9.figshare.c.4457855.

Details

The original study recorded seven days of wrist-worn ActiGraph activity from 20 myoelectric prosthesis users and 20 anatomically intact adults. This package data object is a processed minute-level recording drawn from that collection.
