Prepare the Data
================

The weatherAUS data comes from the Rattle package
(https://rattle.togaware.com). It covers some 50 weather stations in
Australia with over 10 years of daily observations of some 20
variables. The data is loaded, cleansed and wrangled, and prepared for
modelling, as explained in the OnePageR chapter on data templates:

https://onepager.togaware.com/Chapter_Data_Template.html.

A view of the data is shared below.
