cleaning updates

[carriewright11]

• first summary slide has a typo at the bottom and could remove the all() function
• maybe remove some of the inf and nan discussion - and just say other functions do not necessary catch these? (still need to show is.na())

[carriewright11]

• let's add a slide about using : with unite - we ended up having more time and I think it is useful, especially if we drop or simplify some of the inf and nan stuff

• let's add TRUE ~Treatment to all of the case_when code after the first time, as it is better practice (then we don't need Ginger == Ginger)

[carriewright11]

• let's change ^o|^O to just be o|0 but tell people about how you could use ^ or $ on another slide with an example with this data

[carriewright11]

could split up the second lab into two sections cause we ended early but that might be just cause we didn't split into breakout rooms. If we do this it could be nice to add a question using filter and str_detect

[carriewright11]

• add dplyr cheatsheet for case_when()
