multi_frag: Fragmentation of Mulitple Subjects

In muschellij2/fragmentation: Fragmentation Methods for Accelerometry Data

Description

Fragmentation of Mulitple Subjects

Usage

multi_frag(counts, weartime, id = "ID", visit = "visit",
  thresh.lower = 100, bout.length = 1)

Arguments

counts	A data.frame of multiple (or 1) rows with 1441 or 1442 columns.
weartime	data.frame of same dimension as counts and must consist of 1's and 0's. If unspecified, assumed to be when counts > 0.
id	column name/variable in counts and weartime corresponding to an ID.
visit	column name/variable in counts and weartime corresponding to a visit. If not only one visit per id, set this to NULL
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 = example_activity_data$counts
weartime = example_activity_data$weartime
res = multi_frag(counts, weartime = weartime, thresh.lower = 100)
