[英]R leaflet package produces blank (grey) map [Ubuntu 14.04]
I tried out the examplecode from the leaflet
package doc: 我尝试了leaflet
包doc中的examplecode:
devtools::install_github("rstudio/leaflet");library(leaflet)
m <- leaflet() %>%
addTiles() %>% # Add default OpenStreetMap map tiles
addMarkers(lng=174.768, lat=-36.852,
popup="The birthplace of R")
m # Print the map
but it only produced a grey, blank map in the RStudio Viewer, as well as in my Firefox 38.0. 但它在RStudio Viewer和Firefox 38.0中只生成了灰色的空白地图 。 Maybe this has something to do with Ubuntu? 也许这与Ubuntu有关?

I had this issue, but there was no proxy issues (I was admin, it was at home etc) The basemap showed for me in RStudio, but not in html. 我遇到了这个问题,但是没有代理问题(我是管理员,在家里等)。底图在RStudio中为我显示,但在HTML中却没有。
The solution is simply reminding leaflet what the basemap is. 解决方法是简单地提醒传单底图是什么。 It defaults to OSM in RStudio output, but then didn't export it with html. 它在RStudio输出中默认为OSM,但随后未使用html导出。
I simply added the tag 我只是添加了标签
%>% addProviderTiles(providers$OpenStreetMap) %>%
Use 采用
names(providers)
to see all providers of basemaps. 查看底图的所有提供者。
I had the same problem. 我有同样的问题。
Resolved for me by specifying urlTemplate
parameter in addTiles()
: 通过在addTiles()
指定urlTemplate
参数为我解决了:
library(leaflet)
leaflet() %>%
addTiles(urlTemplate = 'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png')
I get the same thing. 我也一样 Same happens for me when I am work. 我上班时也会遇到同样的情况。 I think that the corporate IT dept. 我认为公司的IT部门。 is blocking certain network traffic. 正在阻止某些网络流量。 Try it again at home. 在家里再试一次。
Hope that helps. 希望能有所帮助。
