Time series with twice daily frequency in R

Question

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,...)

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

Answer 1

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.
