The folder does not even exist until the moment of rendering (i.e. when printed). But you can maybe use htmlDependency to add such a folder?

Today I set myself a challenge to apportion ABS mesh block data to H3 hexes. It turns out that sf::st_intersect works like an inner join on the non-geometry columns... This makes this task ridiculously simple and holy smokes I am stoked.

Hi y'all! I think I didn't mention it earlier but even though I work with R I have no formal education in programming/math whatsoever. I have a bachelor from theatre theory & critics 🎭 So, if you for any reason think you can't work with R, stop thinking that! You can do it!

Is your app actually crashing now when errors occur? And by "crashing" do you mean the session that caused the crash is disconnected with a grey screen?

You'd just use tryCatch in Shiny

Are the markers where you'd expect them to be, relative to the map background tiles?

(If it's still blank then it's probably some kind of connectivity issue, you should at least see OpenStreetMap tiles)

What do you see if you remove addMarkers?

Ah, you beat me to it! mapview too. (I always think of leaflet first but the higher level packages are surely better for this)

What happens if you drop it on a leaflet map? leaflet(data) %>% addTiles() %>% addMarkers()

It is possible when using Leaflet together with Shiny. Do you have an example we can start from?

I was introduced to someone today who was like, "Oh, I know you from your PCA answer on Stack Exchange." That the most read thing I will probably ever write:

Ah yes, I've always thought SF was the ideal city to appreciate our planet's two suns.

Well I asked if anyone wanted to ideate or synergize, or maybe collaborate on some UML diagrams, but no takers...
