Assignment (<- not =)
In style/syntax.qmd under Assignment it says: Use <-, not =, for assignment.
Why, though? An explanation would be helpful, especially for newcomers. <- seems unnecessary bordering on obtuse to people coming from other languages, so giving them a good explanation might help to enforce this suggestion.
Others will probably chime in, but here is one reference to support this rule:
cf. https://www.burns-stat.com/pages/Tutor/R_inferno.pdf#page=94.19
Worth noting that the style guide also discourages implicit assignment:
https://github.com/tidyverse/style/blob/315943b66a6194c0b4f3b76fd2f4c12116e21b4b/syntax.qmd#L283-L286
So the above example already violates the guide.
