France is missing

[matteodefelice]

This happens both with the CRAN and the devtools versions of this package.

eu_sf <- ne_countries(scale = 50, returnclass = 'sf')
eu_sf %>% dplyr::filter(iso_a2 == 'FR') %>% nrow()
[1] 0

Is the same with iso_a3 or other fields. France is missing. It is instead present when the scale is 110.

I was wondering if this is still an issue? It is working for me.

 eu_sf <- ne_countries(scale = 50, returnclass = 'sf')
 eu_sf %>% 
   dplyr::filter(iso_a2 == 'FR') %>% 
   nrow()
[1] 1

It's still an issue, both , bdownloading rnaturalearth from CRAN or from the github repository.

Can you provide your sessionInfo()?

Also what does the non-filtered eu_sf return?

eu_sf is this (showing only the first lines of output)

For some reason I end up with a different simple feature. The order and number of variables that my eu_sf ends up different. It might be worth trying to update the rnaturalearthdata package. I don't know if that will fix it though.

So I used the ne_download function and ended up with (I think) the same data you have (note that the variable names are capitalized here):

eu_sf <- ne_download(scale = 50, type = "admin_0_countries", returnclass = "sf") 

eu_sf %>%
  dplyr::filter(ISO_A2 == 'FR') %>% 
  nrow()

However, when I explored the eu_sf object more, there is a row for France, but the ISO_A2 field is NA. So the following seems to work:

eu_sf %>%
  dplyr::filter(FIPS_10_ == 'FR') %>% 
  nrow()

[1] 1

Would be good to troubleshoot how we ended up with different simple features using ne_countries().

[matteodefelice]

Thanks, using fips_10 works but of course is not the same, I want to use ISO codes. It is curious that ne_download and ne_countries return different things.

[mps9506]

Understandable. I dug around some more. It looks like the missing ISO codes are a tracked issue over in the Natural Earth repo: https://github.com/nvkelso/natural-earth-vector/issues/284#issue-425441544

Seems to be working properly in the current version of the package. Please feel free to reopen if you still experience issues.

I am using the most recent rnaturalearth package and France and Norway are still missing from the variable 'iso_a3'. However, they are present in 'iso_a3_eh'. So for example, you could replace missing values with those to get the full map.

wi_map <- ne_countries(returnclass = "sf") %>% # generate wi_map object

  mutate(id = iso_a3,
         id = ifelse(id == "-99", iso_a3_eh, id)) %>% # replace missing codes for FRA and NOR

  select(id, geometry)
