R中每日频率两次的时间序列 [英] Time series with twice daily frequency in R

问题描述

我有一些来自传感器的数据，每 12 小时进行一次观察.我想将其分析为时间序列，但我不确定使用什么频率将其转换为时间序列.ts 函数需要一个开始、一个结束和一个频率.ts(data, start = 1, end = numeric(), frequency = 1,...)

I have some data coming from sensors with observations every 12 hours. I want to analyze it as time series, but I not sure what frequency to use to convert it to time series. The ts function needs a start, an end and a frequency. ts(data, start = 1, end = numeric(), frequency = 1,...)

我不想将其汇总为每天一次的频率(可能会丢失一些信息).有什么建议吗?

I do not want to aggregate it to once daily frequency (will likely lose some information). Any recommendations?

推荐答案

ts 类不能很好地处理高频数据.我建议你改用 tsibble 类.请参阅 https://cran.r-project.org/package=tsibble.feasts 和 fable 包提供了许多为 tsibble 对象设计的建模工具.

The ts class does not handle high frequency data very well. I suggest you use the tsibble class instead. See https://cran.r-project.org/package=tsibble. There are many modelling tools designed for tsibble objects provided by the feasts and fable packages.
