Here is a leaflet map in R
The white lines are neighbourhood boundaries. The green polygons are parks. The parks are drawn over the boundaries obscuring the borders. I want the white neighbourhood boundaries to be drawn on top of the parks so that the entire border is seen.
This sounds like an issue of layer ordering.
I thought I could use zIndex with leaflet to solve the problem. I've tried hoods = 200, parks = 300 and hoods = 200, parks = 100. I can't get it to work.
The relevant code:
# Add neighbourhoods addPolygons(data = hood_shp, fillColor = ~pal(be_per_cap), weight = 2, opacity = 1, color = "white", dashArray = "0", fillOpacity = 1.0, options = list(zIndex = 200) %>% # Add parks addPolygons(data = parks, color = "green", weight = 1.0, opacity = 1.0, options = list(zIndex = 300), fillOpacity = 1.0)
