我正在为一个项目创建一个带有传单和 R 的 HTML 文件。想法是在地图中添加多个标记，并且能够单击它们并查看描述和图片。这是示例代码。
library(sp)
library(leaflet)
suppressPackageStartupMessages(library(imager))
coor<-c("11","-55","EG",
"12","-54","EG2")
df<-matrix(coor,ncol=3,byrow = TRUE)
df<-data.frame(lon=as.numeric(df[,1]),lat=as.numeric(df[,2]),Iden=df[,3])
descr<-c("Description written in popup.
\n <img src=\"/A:/Path/FIle/Pics/EG.jpg\">",
"description 2 \n <img src=\"/A:/Path/FIle/Pics/EG_2.jpg\">")
df<-cbind.data.frame(df,descr)
colnames(df)[4]<-descr
coordinates(df) <- ~lat+lon
leaflet(df) %>% addMarkers(popup = ~descr,label = ~Iden) %>% addTiles()
如果我在我的电脑中打开该文件，图片会正确显示，但是，当在其他设备中使用该文件时，图像不存在，因为
img src您可以使用 base64 将图像编码为 URL（例如，请参阅此网络服务）
示例图片：https://cdn.sstatic.net/Sites/stackoverflow/Img/favicon.ico?v=ec617d715196
