是否可以根据传单 R 的因子变量显示圆圈的大小

Question

我正在尝试使用 R 中的传单包创建地图。

我希望点的大小取决于分类变量。此变量包含 3 类：[1-5]、[5-10] 和 [10-15]。所以我希望有 3 种尺寸这是允许我制作这张地图的代码：

leaflet(geo)%>% addTiles() %>% addProviderTiles('CartoDB.Positron') %>% addGeoJSON(geojson, weight = 2, color = "#000000", fill = FALSE) %>% 
  addCircleMarkers(~LONGITUDE, ~LATITUDE, weight = 4,radius = ~0.25, opacity = 0.9, color = ~pal1(NETWORK_TYPE_FOR_PERIOD)) %>% 
  addLegend(pal = pal1, values = ~sort(NETWORK_TYPE_FOR_PERIOD), opacity = 0.8, title = c(""),
            position = "bottomright")

Answer 1

能否给数据集添加分组变量：

geo %>% mutate(grouping_var = case_when(
     `your character variable` == "character value"~ 50,
     `your character variable`== "character value"~ 100),
     grouping_var = as.numeric(grouping_var ))

然后只需将半径从 radius = ~.25 更改为 geo$grouping_var

是否可以根据传单 R 的因子变量显示圆圈的大小

is it possible to display the size of the circles according to a factor variable with leaflet R

r

leaflet
