Feed observations to a monitor

Source: R/monitor.R
cpt_update.Rd

Pushes new data through a cpt_monitor(), updating its internal state and appending to its alarm log. The monitor is returned, so the idiom is mon <- cpt_update(mon, new_obs).

Usage

cpt_update(monitor, new_obs)

Arguments

monitor

A ggcpt_monitor object.

new_obs

New observations: a numeric vector, or a matrix with rows as time points for a multivariate monitor.

Value

The updated ggcpt_monitor: the same structure as the input (see cpt_monitor()), with t advanced by the number of new observations (rows, for a matrix) and any new rows appended to alarms. Re-assign it: the monitor is a value, not a mutable object, so cpt_update(mon, y) without assignment discards the update.

See also

cpt_monitor(), alarms().

Examples

set.seed(2026)
mon <- cpt_monitor("edetector", baseline = rnorm(100))
mon <- cpt_update(mon, c(rnorm(50), rnorm(50, 3)))
alarms(mon)
