Html 在R中自定义单张弹出窗口
我正在使用RStudio创建choropleth传单地图。 我在导入到R的shapefile中有Country和Url作为属性 我希望在最终地图的弹出窗口中以超链接的形式显示国家名称和URL 以下是我迄今为止使用的代码:Html 在R中自定义单张弹出窗口,html,r,leaflet,gis,arcgis-js-api,Html,R,Leaflet,Gis,Arcgis Js Api,我正在使用RStudio创建choropleth传单地图。 我在导入到R的shapefile中有Country和Url作为属性 我希望在最终地图的弹出窗口中以超链接的形式显示国家名称和URL 以下是我迄今为止使用的代码: m <- world_shapefiles %>% leaflet() %>% addProviderTiles(providers$Esri.WorldStreetMap) %>% addPolygons( lab
m <- world_shapefiles %>%
leaflet() %>%
addProviderTiles(providers$Esri.WorldStreetMap) %>%
addPolygons(
label=~country,
labelOptions = labelOptions(style = list("font-weight" = "normal", padding = "3px 8px", textsize = "15px",
direction = "auto")),
popup = ~ paste("Country:", country, "<br/>","<b/>","URL:", url)
)
m%
传单()%>%
addProviderTiles(提供者$Esri.WorldStreetMap)%>%
添加多边形(
标签=~国家,
labelOptions=labelOptions(style=list(“font-weight”=“normal”、padding=“3px 8px”、textsize=“15px”,
direction=“auto”)),
弹出窗口=~粘贴(“国家:”,国家,
“,”,“URL:”,URL)
)
我想看到文本“点击这里”,而不是在弹出的整个网址,我试图使用下面的代码没有运气
popup = ~ paste("Country:", counry, "<br/>","<b/>","URL:", "<b><a href=url>Click Here</a></b>")
popup=~粘贴(“国家:”,国家,“
”,“URL:”,“”)
有什么想法可以实现吗?概述
阅读后,以下是如何修改现有代码:
# it seems ~ doesn't work inside of the paste0() function
# which is why I accessed the variables through the $
popup = paste0( "Country:"
, world_shapefiles$country
, "<br>"
, "<a href='"
, world_shapefiles$url
, "' target='_blank'>"
, "Click Here</a>"
)
#似乎~在paste0()函数中不起作用
#这就是为什么我通过$
弹出=粘贴0(“国家:”
,世界形状文件$国家
,“
”
, ""
)
可复制示例
我使用下载世界上每个国家的形状文件。然后,我为数据集中的每个国家添加一个URL
