CRAN v0.2.1
This release coincides with v0.2.0 of the fabletools package, which contains
some substantial changes to the output of forecast()
methods.
These changes to fabletools emphasise the distribution in the fable
object. The most noticeable is a change in column names of the fable, with the
distribution now stored in the column matching the response variable, and the
forecast mean now stored in the .mean
column.
For a complete summary of these changes, refer to the fabletools v0.2.0 release
