Before you start writing packages…
Set up your system as explained in the R packages book by Hadley Wickham and Jenny Bryan
Learn how to write functions. Some useful links:
If you use GitLab, not GitHub, you can follow Heidi Seibold’s instructions “Setup Git RStudio GitLab”. There is no helper similar to
usethis::use_github() to my knowledge.
You should be able to follow the course and manage a blog without any git knowledge. Now for later, if you feel curious about version control, I’d recommend checking out happygitwithr.com by Jenny Bryan, the STAT 545 TAs, Jim Hester; Suzan Baert’s blog post about git and “Excuse me, do you have a moment to talk about version control?" by Jenny Bryan.
