Include st_queen and st_rook as functions under st_relate

[angela-li]

It would be useful to include st_queen and st_rook explicitly in sf, as versus just in the st_relate documentation (or in the sf Github issues) . It's a common enough operation for spatial weights that I find myself having to look up the DE-9IM pattern or referencing the documentation a lot. It's also hard to explain DE-9IM patterns to people who are just starting to use R for spatial analysis.

It'd be great if it could be included in the package as functions, possibly here?

Please explain why? I think that https://keen-swartz-3146c4.netlify.com/area-data-and-spatial-autcorrelation.html#spatial-weights-matrices is very clear, that just using sf is inefficient (same story in https://r-spatial.github.io/spdep/articles/nb_sf.html#comparison-of-sp-and-sf-approaches). I cannot see any reason to confuse users who might think that sf does statistical analysis, it does not. Packages should have clearly defined tasks. You should never have to look further than documentation that already exists, and that you contributed to (see also https://edzer.github.io/UseR2019/part2.html#graphweight-based-neighbours). Unless you need to teach from DE-9IM, you don't need that listing of relationships.

Agreeing mostly with @rsbivand , in addition I am against adding functions that are one-liners really.
