But after giving quite a few R courses mainly - but not only - for R beginners, I came to acknowledge that the answer to this question is not obvious and the different possibilites can be confusing.

Using custom scales with the ‚scales‘ package

Maybe you already heard of the package “scales” - and if you didn’t hear about it, you might have used it without knowing (e.g., in the context of ggplot2 graphs).

For me, it sounds really logical to blog about R with R (with the help of RStudio).
