frag: Fragmentation

In muschellij2/fragmentation: Fragmentation Methods for Accelerometry Data

Description

Fragmentation

Usage

frag(counts, weartime = NULL, thresh.lower = 100, bout.length = 1, ...)

Arguments

counts	Matrix of multiple (or 1) rows with 1440 columns.
weartime	Matrix of same dimension as counts and must consist of 1's and 0's. If unspecified, assumed to be when counts > 0.
thresh.lower	Lower cut-off for count values in intensity range. Passed to accel.bouts
bout.length	minimum length of an activity bout. Passed to accel.bouts
...	additional arguments passed to accel.bouts

Value

List of mean rest bout, mean activity bout, the total data, and the reciprocal of the bouts

Examples

counts = matrix(rpois(1440*5, lambda = 5), ncol = 1440)
res = frag(counts, thresh.lower = 2)

counts = example_activity_data$counts
weartime = example_activity_data$weartime
id_to_run = counts$ID[1]
counts = counts[ counts$ID == id_to_run, ]
counts$ID = counts$visit = NULL
weartime = weartime[ weartime$ID == id_to_run, ]
weartime$ID = weartime$visit = NULL

res = frag(counts, weartime = weartime, thresh.lower = 100)
