R中每日频率为两次的时间序列 [英] Time series with twice daily frequency in R

问题描述

我每隔12小时就会从传感器中获得一些数据，并进行观测.我想将其分析为时间序列，但是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(数据，开始= 1，结束=数字()，频率= 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(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.我建议您改用 tsibble 类.请参见 https://cran.r-project.org/package=tsibble .有许多为 feasts 和 fable 软件包提供的 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.
