Question

I tried out the examplecode from the leaflet package doc:

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. Maybe this has something to do with Ubuntu?

Here my sessionInfo:

Answer 1

我有这个问题，但没有代理问题（我是管理员，它在家里等）底图在RStudio中为我显示，但在html中没有显示。

解决方案只是提醒传单底图是什么。它默认为RStudio输出中的OSM，但后来没有用html导出它。

我只是添加了标签

%>% addProviderTiles(providers$OpenStreetMap) %>%

使用

names(providers)

查看所有底图提供商。

Answer 2

我遇到了同样的问题。

通过在urlTemplate中指定addTiles()参数来解决此问题：

library(leaflet)
leaflet() %>% 
  addTiles(urlTemplate = 'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png')

Answer 3

我得到同样的东西。我上班的时候也是如此。我认为是企业IT部门。阻止某些网络流量。在家里再试一次。

希望有所帮助。
