stats_sf can't find geometry aesthetics

[jlacko]

Your code is complex and not quite easy to troubleshoot; it might be a good idea to reframe the issue you are facing in as simple format as possible. What you share is quite a chunk...

For a simple example of spatial data frame animated via {gganimate} consider this post; it builds on the pressure dataset that is shipped with base R and the North Carolina shapefile that comes with {sf}.

Best packages for making map? leaflet vs ggmap vs sf vs ...?

I think that ggplot and leaflet will handle most of your needs. A honorable mention goes to tmap package - https://github.com/mtennekes/tmap. It introduces yet another map making syntax, and produces decent maps with very little tweaking. It supports both static and dynamic output. But competing against ggplot in static maps is hard, and in dynamic mapping using leaflet directly gives you more control. If you are familiar with ggplot syntax I would leave it out. And as my curiosity got the better of me I propose a workflow for animated maps, built on ggplot and gganimate. The hardest part was faking the data to be animated; at the end I ended up recycling the well known & loved pressure d…
