Imagination along with technical prowess makes this RU-vid lesson on line charts invaluable. I wonder if you could share the source of the Okabe Ito color palette you displayed in your presentation (minute 4:14).
Good question. I'm not so sure where I got the image from. But in general I take the hex codes often from mikemol.github.io/technique/colorblind/2018/02/11/color-safe-palette.html
That's R's own pipe operator. Since R 4.1 there is one and I use that because it doesn't require me to load the magrittr package to use a pipe. R's build-in pipe works mostly the same but there are two major differences. The right-hand side always has to be a function call, i.e. end with parantheses (), and if you want to insert the left-hand side of the pipe into a particular position, then you have to use an underscore as in function(x = _). This works only with named arguments though.
