RA

Relative Amplitude

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

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

`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

count1 = c(t(example_activity_data$count[1,-c(1,2)]))
