元数据中的错误？

Errors in the metadata?

提问人：Weiss 提问时间：11/15/2023 最后编辑：Weiss 更新时间：11/16/2023 访问量：120

问：

我用 R 编写了一个代码，其中从两个表中读取 lat 和 long，并在地图上用不同的颜色绘制。

这两个表的结构如下：

enter image description here

（我检查了所有实体，它们都是正确的）

我的环境是这样的

enter image description here

代码如下所示：

install.packages('readxl')
library(readxl)

data_a <- read_excel('C:/Users/Location_map.xlsx', sheet = 'Core_Tops')
data_b <- read_excel('C:/Users/Location_map.xlsx', sheet = 'Tows')
lat_a <- data_a$Lat
lon_a <- data_a$Long
lat_b <- data_b$Lat
lon_b <- data_b$Long

# until this point the code works very well :D

install.packages('leaflet')
library(leaflet)

map <- leaflet() %>%
  addTiles() %>%
  addMarkers(lng = lon_a, lat = lat_a, icon = ~colorIcon("blue",iconSize = c(20, 20))) %>%
  addMarkers(lng = lon_b, lat = lat_b, icon = ~colorIcon("red",iconSize = c(20, 20)))

map

当我执行它时，我收到以下错误消息：

Error in UseMethod("metaData"): inapplicable method for 'metaData' applied to object of class "NULL"

以下我尝试：

 dput((data_b))

答案是：

 dput((data_b))

什么 R 包给你 colorIcon ？

AFAIK 传单包装中没有“colorIcon”功能。
