IS_long: Interdaily Statbility for the Whole Dataset

In ActCR: Extract Circadian Rhythms Metrics from Actigraphy Data

Interdaily Statbility for the Whole Dataset

Description

This function calcualte interdaily stability, a nonparametric metric of circadian rhtymicity. This function is a whole dataset wrapper for IS

Usage

IS_long(count.data, window = 1, method = c("average", "sum"))

Arguments

count.data	data.frame of dimension n * (1440+2) containing the 1440 dimensional activity data for all n subject days. The first two columns have to be ID and Day. ID can be either character or numeric. Day has to be numeric indicating the sequency of days within each subject.
window	an integer indicating what is the window to bin the data before the function can be apply to the dataset. For details, see bin_data.
method	character of "sum" or "average", function used to bin the data

Value

A data.frame with the following 2 columns

ID	ID
IS	IS
