我正在尝试在 Lambert 93 (st_transform(2154)) 中制作一张传单地图，其中包括：1.多边形（法国）2.光栅层（欧洲）
我不明白为什么以下代码不起作用。
library(leaflet)
library(tidyverse)
library(sf)
library(grid)
library(fasterize)
library(cartography)
library(mapview)
sf_europe <- cartography::nuts0.spdf %>% st_as_sf %>% mutate(num=ifelse(id=="FR",1,0)) %>% st_transform(2154)
r <- raster(sf_europe, res = 10000)
r <- fasterize(sf_europe, r, field="num",background = 2)
epsg_affichage <- leafletCRS(crsClass = 'L.Proj.CRS', code = 'EPSG:2154',
proj4def = "+proj=lcc +lat_1=49 +lat_2=44 +lat_0=46.5 +lon_0=3 +x_0=700000 +y_0=6600000 +ellps=GRS80 +units=m +no_defs",
resolutions = c(65536, 32768, 16384, 8192, 4096, 2048)
)
sf_france_4326 <- sf_europe %>% filter(id=="FR") %>% st_transform(4326)
leaflet(options =
leafletOptions(maxZoom = 5,
crs = epsg_affichage
)) %>%
addGraticule(style= list(color= '#999', weight= 0.5, opacity= 1)) %>%
addGraticule(sphere = TRUE, style= list(color= '#777', weight= 1, opacity= 0.25)) %>%
addFeatures(data=sf_france_4326) %>%
addPolygons(data=sf_france_4326, color = "red", fill = NA) %>%
addRasterImage(r, project = FALSE)
这是会话信息

事实上，光栅似乎在错误的位置。欧洲在澳大利亚（见图），我真的不知道如何解决这个问题。
谢谢你的帮助！
