我使用以下命令：
library("strucchange")
z <- read.zoo(text = Lines, tz = "", format = "%d/%m/%Y %H:%M", sep = ",")
bp <- breakpoints(z~ 1, h = 36)
> bp
Optimal 1-segment partition:
Call:
breakpoints.formula(formula = z ~ 1, h = 36)
Breakpoints at observation number:
NA
Corresponding to breakdates:
NA
我想找到细分。每天我发现最佳3段分区。然而，3天（72小时）没有发现任何部分。如何找到12个段（断点）？
