Error with print_osm_map

[maelle]

Noticed this while preparing a blog post that'll feature the very cool osmdata and osmplotr 😉 I'm using ggplot2 latest version, maybe that's the issue, but I don't see anything amiss on CRAN. 🤔

library("osmplotr")
#> Data (c) OpenStreetMap contributors, ODbL 1.0. http://www.openstreetmap.org/copyright
bbox <- get_bbox (c(-0.15, 51.5, -0.10, 51.52))
map <- osm_basemap (bbox = bbox, bg = 'gray20')
print_osm_map (map)
#> Error: Discrete value supplied to continuous scale

Oh it's just because you can't plot an empty map sorry 🤦‍♀️

[mpadge]

Yeah, you figured it out right. I'll look out for the blog - how exciting for me! I also just landed in Brisbane for User18. Also exciting!

[maelle]

Have an awesome time at UseR!

I'll probably send my code your way when I'm done, for a short review 👼

[mpadge]

Yes please!!!

I'm running into this issue presently. I'm not able to understand why I cannot simply create a base map and add it to a ggplot that does not use any other OSM data.

Is osmplotr::osm_basemap() just an empty ggplot layer?
