Change options on layer groups. Currently the only option is to control what
zoom levels a layer group will be displayed at. The
is not compatible with layers control; do not both
assign a group to zoom levels and use it with
groupOptions(map, group, zoomLevels = NULL)
the map to modify
character vector of one or more group names to set options on
numeric vector of zoom levels at which group(s) should be
pal <- colorQuantile("YlOrRd", quakes$mag) leaflet() %>% # Basic markers addTiles(group = "basic") %>% addMarkers(data = quakes, group = "basic") %>% # When zoomed in, we'll show circles at the base of each marker whose # radius and color reflect the magnitude addProviderTiles(providers$Stamen.TonerLite, group = "detail") %>% addCircleMarkers(data = quakes, group = "detail", fillOpacity = 0.5, radius = ~mag * 5, color = ~pal(mag), stroke = FALSE) %>% # Set the detail group to only appear when zoomed in groupOptions("detail", zoomLevels = 7:18)
