Cleaning data notes

[avahoffman]

• Could simplify the ufo read-in (currently read_delim, could be read_csv instead)
• Typo in the summary on slide 26 (.default spelled incorrectly)
• Noticed in Part 2 lab, if we filter based on the min string, "undetermined" shows up 😅

• update regex doc to point to rstudio cheatsheet
• maybe add something about looking for an escaped value as practice on your own but optional (for part 2)

thanks @avahoffman !!

someone asked about the cleaning process which was interesting... I said this - maybe interesting to add a resource (from someone else or me... or a simple slide):
look at the data
check for classes of variables (maybe update - factors too!)
check for missing data
check for duplicates
check for rare values (didnt say this but you should :P)
recode variable names as needed
recode values as needed

I also pointed out that we might need to reshape the data or join in new data

• show how some of the toy datasets are made for people following along (for both i think but especially part 2)

subsetting might have had some toy datasets too but I can't recall
