传单地图的空白、白色背景

Question

I would like to make a leaflet map with a white background -- that is with either no tiles at all and with a white background, or with tiles that are all white.

Here's the leaflet "hello world":

library(leaflet)

leaflet() %>%
  addTiles() %>%
  addMarkers(lng=174.768, lat=-36.852, popup="The birthplace of R")

Leaving out the addTiles() gives me a grey instead of a white background and none of the tiles in the gallery are all white.

Answer 1

Thanks to @JoSerra for the pointer, here's how to achieve this in the context of an RMarkdown document. Just add the following to the doc:

```{r results="asis"}
cat("
<style>
.leaflet-container {
    background: #FFF;
}
</style>
")
```
