All background maps are blank.

[ojlise]

When plotting data on mapview in R, the data points show up, but the background maps do not. I am behind a firewall so I have to use a proxy to get the data. Do I have to set up something similar to be able to load the background maps?

I'm suspecting that the loading of the maps are being stopped by the firewall.

So I end up with a bunch of dots on a blank background.

I'm having the same issue here with both sf and sp object types. However, I can load a map using breweries just fine. So, likely something with how I'm formatting my data...
Example data and code:

#Load packages
library(tidyverse)
library(sf)
#Create example data
latitude = c(44.10606, 44.10668, 43.69781, 43.58378, 43.83922, 43.84134)
longitude = c(-124.0897, -124.0890, -122.0458, -122.7138, -122.5581, -122.5467)
#Make spatial dataframe
data = data.frame(latitude, longitude) %>%
  st_as_sf(coords = c('longitude', 'latitude'))
#Generate map (without basemap)
mapview(data)

I am using R v. 4.2.2 in RStudio v. 2022.2.04 on Mac OSX v. 10.15.7. I'm using mapview v. 2.11.0, sf v. 1.0-9, sp v. 1.6-0.

I have found that this just happens within the Rstudio viewer pane and again on a corporate network so it could be something blocking the Viewwer pane from calling urls. A workaround is to click the icon to view the map in a new window which opns it in a browser. from memory the Rstudio Viewer is a type of browser (within a web app which is what Rstudio is)
