One resource we didn’t discuss today, but that is really good is from the 2020 R for Excel Users workshop by Julie Lowndes and Allison Horst. They discussed Git/GitHub in that workshop and have a really nice overview of how it works.
The other thing that we discussed, following up on a question from @clint-thomson
is removing rows with NA’s. In addition to the examples we gave in the session, another idea I came up with afterward is to use the naniar package. You’ll see in the code I wrote that I added a few lines using naniar to show how you might identify rows with all blanks minus the first ID column.
