When I try to produce a self-contained html mapshot from the mapview package, it saves a separate folder with files, nevertheless. Also, it produces an error 99 which I could not get solved (but it still produces a working html).

Here a reproducible example:

library(mapview)
m = mapview(breweries)
m
## create standalone .html
mapshot(m, url = paste0(getwd(), "/map.html"), selfcontained = TRUE)

This gives me a nice html, but it is not self-contained. I get an html file and a folder called "map_files" that carries subfolders with js-files. Also it gives out the following error:

File map_files/PopupTable-0.0.1/popup.css not found in resource path
Error: pandoc document conversion failed with error 99

    The error should go away if you upodate from github `remotes::install_github("r-spatial/mapview")` – TimSalabim Nov 27 '20 at 07:44
  • Thank you! It worked for the reproducible example! It doesn't work for my actual code (yet), though. The error is gone, but for my actual code it still is not a self-contained html. – Samuel Nov 28 '20 at 10:47
  • Okay, I found something interesting: If you change the `url` to something other than the working directory, it does not give it as a self-contained file. e.g. `mapshot(m, url = paste0(getwd(), "/projects/map.html"), selfcontained = TRUE)` does not produce a self-contained file in the projects-folder but gives an html plus a folder with scripts. Do you have any idea why @TimSalabim ? – Samuel Nov 28 '20 at 11:15
  • What gdal version do you have? Does it work if you set `mapviewOptions(fgb = FALSE)`? – TimSalabim Nov 28 '20 at 15:19
  • I have rgdal 1.5-18 It is funny, I found out that it works if you put the path right in the working directory, but not if it is in a subfolder. – Samuel Dec 07 '20 at 21:59
  • When I execute `mapviewOptions(fgb = FALSE)`, a warning comes: option 'fgb' requires GDAL >= 3.1.0! Your version is 3.0.4. Setting fgb = FALSE It still doesn't work to produce a self-contained html outside in a subfolder. – Samuel Dec 07 '20 at 22:09

    Then I am out of ideas, might be something to do with `saveWidget`... – TimSalabim Dec 08 '20 at 07:34
  • Thank you, nevertheless, for now, the workaround is to set and reset the working directory :) – Samuel Jan 10 '21 at 20:51
