I was trying to apply to my use case and no polygons were showing up, so i tried with the basic example with the package readme, and no points showed up in that application either.
library(leaflet)
library(leafgl)
library(sf)
n = 1e6
df1 = data.frame(id = 1:n,
x = rnorm(n, 10, 3),
y = rnorm(n, 49, 1.8))
pts = st_as_sf(df1, coords = c("x", "y"), crs = 4326)
options(viewer = NULL) # view in browser
leaflet() %>%
addProviderTiles(provider = providers$CartoDB.DarkMatter) %>%
addGlPoints(data = pts, group = "pts") %>%
setView(lng = 10.5, lat = 49.5, zoom = 6)
(The base tiles open in the browser, but the points don't render)
