Maps – tmap, leaflet, sf, spdplyr, cartography, etc. #1

The easiest solution might be to teach only one method, possibly one that works with both choropleths and geocoded points. Pinging @rCarto in case he might have some suggestions. |
IMHO the packages you're mentionning are dealing with very different tasks (as the rspatial discussion makes it clear), using very different paradigms and operating at vastly different levels of maturity. So I think in the context of an introductory workshop to R, it is important to focus on 1/ a more-or-less coherent paradigm 2/ stable solutions 3/ one of the steps of the workflow @tim-salabim identified. My advice at this point would be to focus on the rgdal/sp tools to import and contain data, as this is definitely what's most mature at the time. Then you have two great mapping packages IMHO, |
I agree that the cited packages are different and unequally advanced. More thinking aloud below. Basically, to me, there's three choices (leaving Leaflet out).

I can help you ggplot with sf already, if needed. It's good for learning if nothing else. |
Hi @mdsumner Thanks for offering to help. If you look at the draft syllabus, there is a section on data visualization. I would like to include a single exercise involving maps, ideally using GADM and involving both choropleths and a 'bubble map' or something like that. My guess is that the exercise would start with Here are some candidates for the exercise:
Feel free to chime in if you have suggestions for the exercise :) Cheers, ƒ |
P.S. @joelgombin and @rCarto are naturally welcome to submit ideas too! |
and dev mapview and now leaflet also supports sf: rstudio/leaflet#350 So it will be pretty easy to use, unless you need to teach before those updates are released to CRAN. I probably won't get to explore those links but feel free to ask specific questions. |
This rocks, I'll explore and see if I can teach with that (the workshop starts in February). |
This looks like a map that I'd be happy to reproduce with R: https://visionscarto.net/global-nuclear-power-database I'm posting some other suggestions in the other issues of this repo. |
Well, I may have some ideas on how to reproduce this map. I'll let you know if I managed to. |
Many thanks! |
The conversation over at tim-salabim/rspatial/issues/9 is getting somewhere. @edzer just posted a detailed text that links to and all the other relevant places to monitor. The rspatial.org website (which still has a few work-in-progress missing sections) has nice examples of using @edzer has also written a very nice list of … and is continuing the work on |
Last thing: the new repo to watch for discussions is r-spatial/discuss. |
Replaced by #30 |
… and the list goes on: see my blog post on the issue (kind of).
Some folks are putting ideas together on the topic.
