IV_long

Intradaily Variability for the Whole Dataset

Description

This function calcualte intradaily variability, a nonparametric metric reprsenting fragmentation of circadian rhtymicity. This function is a whole dataset wrapper for IV.

Usage

IV_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 5 columns

`ID`	ID
`Day`	Day
`IV`	IV
