Restructure Cleaning and Wrangling Data Lesson

[camilavargasp]

Resources to look into

• Allison's intro to dplyr

General Notes

• How to make the introduction more streamlined? I introduced the 1st example directly in R, but looking back I would explain the code first, to make sure everyone understands what is happening conceptually, and then jump into coding. Maybe the theoretical explanation of Split-Apply-combine explanation can go right before introducing group_by() + summarize()?

• How to better explain summarize(n = n())? Participants had issues understanding the "behind the scene of this step.

Specific changes

• Remove the View(catch_original) in 7.3 Exploring data. This causes errors when rendering the Rmd. I think is cool to talk about the View() function but do it in the console.

Hi Camila,

Thanks for the comments. I looked at the previous Delta lesson and will implement the suggestions you mention here. In particular, about the intro: I was actually thinking of cutting out all coding chunks from the intro since it doesn't seem the best section to start explaining things into detail. Instead:

• move the split-apply-combine explanation to the group_by()+summarize() section like you suggested. I'll do that.
• combine some of the pivot_longer example in the intro into the pivot_longer section.
