更改leaflet中线条的宽度

Question

有没有可能使黑色线条变细？这里有一个可重现的例子，也可以看看这里：

library(leaflet)
leaflet() %>%
  addTiles() %>%
  addProviderTiles(providers$OpenStreetMap, group = "OSM") %>%
  addProviderTiles(providers$Stamen.TonerLite, group = "Toner Lite") %>%
  addLayersControl(baseGroups = c("OSM", "Toner Lite")) %>% 
  leaflet::addCircleMarkers(lat = 0,
                            lng = 0,
                            color = "black",
                            fillColor = "red",
                            stroke = TRUE,
                            popup = "hello",
                            radius = 10,
                            fillOpacity = 0.7)

您可以使用weight参数来指定描边的粗细：

library(leaflet)

leaflet() %>%
  addTiles() %>%
  addProviderTiles(providers$OpenStreetMap, group = "OSM") %>%
  addCircleMarkers(lat = 0,
                   lng = 0,
                   stroke = TRUE,
                   weight = 1)

leaflet() %>%
  addTiles() %>%
  addProviderTiles(providers$OpenStreetMap, group = "OSM") %>%
  addCircleMarkers(lat = 0,
                   lng = 0,
                   stroke = TRUE,
                   weight = 100)
