Tidy time series: ‘tsibble’ and ‘feasts’

R packagesLeave a comment

This post is not to announce something related to my own packages, but to highlight Rob Hyndman’s new packages for working with time-series data using a tidy approach. If you have to deal with time series in R, you should have a look at these packages and read the posts with examples of their use at the Hyndsight blog.

I suspect more is to come soon, but for the time being have a look at what Rob Hyndman wrote yesterday and today in his blog.
