Examples
x <- signal_mix(seed = 2026)
attr(x, "true_changepoints")
#> [1] 300 700 900 1300 1600
# the linear ramps are not level shifts, so a mean-change detector puts
# changepoints inside them rather than at the segment joins
cpt_detect(x$value, method = "pelt")$changepoints$cp
#> [1] 406 569 1012 1138 1257 1705 1893
