Difference between internal objects world and worldMap breaks checkBorders

[ggrittz]

A single location in plantR::worldMap does not exist in plantR::world: the "caspian sea".
Here:

> setdiff(worldMap$NAME_0, world$name)
[1] "caspian sea"

Because of this, the internal function plantR:::shares_border does not work

>     share_border <- suppressMessages(suppressWarnings(shares_bord(country.shp[check_these], 
+                                                                   country.gazet[check_these])))
Error in (function (country1 = "brazil", country2 = "argentina")  : 
  Country name(s) 'caspian sea' not found

My first intuition is just to remove "caspian sea" since it is not a country...but since GADM considers it to be a separate administrative unit that is shared between five countries, it is also possible to simply add it to the world object.

This was was finally not as easy as I though beacuse I was not able to reproduce the code that I used to create the map anymore. Natural Earth no longer provides the 258 countries at scale 110m, but only 177. Most of small islands where removed, creating a greater mismatch between objects worldMap and worl. I tried to download the data at the 10m scale and simplify it, but the object become too big. I also downloaded the shapefile of the tiny countries, but htere was too much manipulation due to mismatches between shapefiles. So, a quick fix was to save a copy of the old version world object within the raw data and just add the new corrections and polygons. Not the best solution, but it should work for now.

Need to think of a best solution for the future.
