example data may change format

[tobyhodges]

The main example dataset used here, ratdat, may change format to provide data as tibbles instead of the current data.frame. We should keep an eye on this and adjust the lesson accordingly if and when we need to.

At the moment, tibbles are first encountered and discussed in the last episode of the lesson (Working with Data), but if this change is made to ratdat the complete_old dataframe used throughout episode 2 and a chunk of episode 3 will become a tibble. Some of the content from Working with Data would need to be moved earlier in the lesson, and some of the explanation will probably need to be adjusted to account for the fact that learners would not yet have had the opportunity to get to grips with all of the concepts involved.
