Works for me with mapshot2()
.
Are you using the latest github version or the latest CRAN version?
Hi @tim-salabim , thanks for getting back to me.
I was using the latest CRAN version for my initial post. I installed the Github version (from the master branch) and tried mapshot
again, but got the same result (no raster drawing). With mapshot2
I get the following error:
> mapview::mapshot2(m, file= "mapshot2_image_leaflet_2_2_2-github.png")
Error in sub(file, "", filename) :
invalid regular expression 'C:\Users\DAVID_~1\AppData\Local\Temp\2\RtmpMHcEj6\file1ecc30de3782.html', reason 'Invalid back reference'
In addition: Warning message:

In place of the mapshot2
-only call, I was able to create an output PNG with the workaround below. It is similar to what I was getting before from mapshot
, but the zoom level isn't the same, and I can't figure out if there is a way to adjust that.
output_file <- "map.png"
html_map <- gsub(".png", ".html", output_file)
m <- mapview::removeMapJunk(m, c("zoomControl", "layersControl", "homeButton", "scaleBar", "drawToolbar", "easyButton", "control"))
mapview::mapshot2(m, url = html_map)
webshot2::webshot(html_map, file = output_file, quiet = T)
So it seems this error from my previous message:
> mapview::mapshot2(m, file= "mapshot2_image_leaflet_2_2_2-github.png")
Error in sub(file, "", filename) :
invalid regular expression 'C:\Users\DAVID_~1\AppData\Local\Temp\2\RtmpMHcEj6\file1ecc30de3782.html', reason 'Invalid back reference'
happens only when I specify file
in the mapshot2
call. Potentially because of the location of the intermediate html
file in that case? Maybe this is a Windows-specific issue.
Since I've upgraded to leaflet package version 2.2.2, categorical rasters are not displaying in the
mapview::mapshot
output file:The PNG file shows the basemap only:
Here is what the output file looks like with leaflet 2.2.1:
