After I installed the R 4.0.0, I cannot display the mapview output in the viewer of RStudio. It would be great if someone can give me some hints to solve this.

Here is an example code.

library(mapview)

mapview(breweries)

And here is a screenshot of my RStudio Viewer. There is no error message, but the viewer is just blank.

Here is my session information, and I am using RStudio Version 1.1.442.

  • can you view anything in the viewer, such as a ggplot() graph? – PleaseHelp Jun 11 '20 at 20:25
  • @PleaseHelp Yes, I can. `ggplot` and `base plot` both works. For example, if I do `plot(sf::st_geometry(breweries))`, this gives me a point map. – www Jun 11 '20 at 20:27

    You might want to upgrade your RStudio version -- the most recent release is 1.3 and running your code displays the map fine for me. – mfherman Jun 11 '20 at 21:49

This seems to be an issue of some combinations of RStudio, R and leaflet versions on Windows, see these GitHub issues:

Try to upgrade your RStudio, maybe it'll help (at least they say it's fixed for RStudio v1.3.957-1).
