这是我的数据（dts_trend）：

我想找到断点并为其使用Strucchange包，例如关于页面上的Nile数据的示例：
https://www.r-bloggers.com/a-look-at-strucchange-and-segmented/
（当使用此页面上的Nile示例时，一切正常）
这是我的代码：
library(strucchange)
plot(dts_trend) # the plot is shown ok
bp.dts_trend <- breakpoints(dts_trend ~1) # defining breakpoints
ci.dts_trend <- confint(bp.dts_trend, breaks = 3)
lines(ci.dts_trend)
然后的问题是，代码的最后一行没有显示任何行。
只有我这样做：
plot.new()
lines(ci.dts_trend)
我在空白图上看到了三个垂直线...
我正在努力查看带有dts_trend数据和上面三行的原始图。
