RA2: Relative Amplitude

In postGGIR: Data Processing after Running 'GGIR' for Accelerometer Data

Description

This function calcualte relative amplitude, a nonparametric metric reprsenting fragmentation of circadian rhtymicity

Usage

RA2(x, window = 1, method = c("average", "sum"))

Arguments

x	vector vector of activity data
window	since the caculation of M10 and L5 depends on the dimension of data, we need to include window size as an argument.
method	character of "sum" or "average", function used to bin the data

Value

RA
