This is the world's smallest and most boring analysis: we compute Species-specific median for the sepal and petal variables in the iris data. Yawn. It is meant to be boring, so we can just focus on the progression of small changes made to the source file iris.R.

Check out the commit history, which flows from bottom to top. Click on a commit to see the diff. Starting from the very bottom, I walk through the solo Git workflow depicted in panel C here:

I then reset -- literally, look for the commit with "Reset" as message! I then start over again and walk through the collaborative or, at least, branch-oriented, workflow depicted in panel D above.

I've placed two tags, solo-end and collab-end, to mark the end of each example workflow. I didn't use the tag "draft-01", as I did in the article, because you can't really use the same tag twice in the same repo.

Notice how nice iris.md looks when you visit it in the browser! This file can be produced via rmarkdown::render("iris.Rmd") or, equivalently, rmarkdown::render("iris.R"). If you use RStudio, you can do same by clicking on "Knit" in the .Rmd case or the "spiral notebook" button in the .R case.
