nparACT_base_loop {nparACT} | R Documentation |
Classic Nonparametric Actigraphy Measures for Multiple Actigraphy Files
Description
Function returns IS, IV, RA, L5, M10 as well as L5 and M10 start times for multiple actigraphy files. The function also returns a plot for hourly grand averages across 24 hours.
Usage
nparACT_base_loop(path, SR, cutoff = 1, plot = T, fulldays = T)
Arguments
path |
Character string containing path to location of actigraphy files. Actigraphy files must contain a first column with a date/time vector, which must be of form |
SR |
Sampling rate in Hz. |
cutoff |
Can be used to define a cutoff for actigraphy data. Default value is |
plot |
If |
fulldays |
If |
Value
Data frame containing IS, IV and RA values for each file. Besides this, L5 and M10 values are given along with the respective start times.
