Time: Time of A Certain activity State

In junruidi/actigraphy: Feature Extraction from Minute Level Actigraphy Data

Description

Calculate the total time of being in certain state, e.g. sedentary, active, MVPA, etc.

Usage

Time(x, w, thresh, smallerthan = TRUE, bout.length = 1)

Arguments

x	vector of activity data.
w	vector of wear flag data with same dimension as x.
thresh	threshold to binarize the data.
smallerthan	Find a state that is smaller than a threshold, or greater than or equal to.
bout.length	minimum duration of defining an active bout; defaults to 1.

Value

Time

Examples

data(example_activity_data)
count1 = c(t(example_activity_data$count[1,-c(1,2)]))
wear1 = c(t(example_activity_data$wear[1,-c(1,2)]))
time_sedentary = Time(x = count1, w = wear1, thresh = 100,
bout.length = 1, smallerthan = TRUE)
