A short example to display a map of some institutions with “Stockholm” in their names and located in Sweden:
library(institutions)
library(dplyr, warn.conflicts = FALSE)
library(leaflet)
institutions_download()
stockholm <-
institutions_search("Stockholm") %>%
filter(country_code == "SE")
leaflet(stockholm) %>%
addTiles(
urlTemplate = "//{s}.basemaps.cartocdn.com/light_all/{z}/{x}/{y}{r}.png",
options = tileOptions(maxZoom = 18), group = "Gray", layerId = "test"
) %>%
addMarkers(lng = ~lng, lat = ~lat, popup = ~institutes, label = ~institutes)
