groupOptions

Set options on layer groups

Description

Change options on layer groups. Currently the only option is to control what zoom levels a layer group will be displayed at. The zoomLevels option is not compatible with layers control; do not both assign a group to zoom levels and use it with addLayersControl.

Usage

groupOptions(map, group, zoomLevels = NULL)

Arguments

`map`	the map to modify
`group`	character vector of one or more group names to set options on
`zoomLevels`	numeric vector of zoom levels at which group(s) should be visible, or `TRUE` to display at all zoom levels

Examples

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)
