I have a shapefile that includes an exclave (area that is not connected to the continuous main part), which causes the map to look like this
I tried to work around it by creating a dummy variable for the exclave and use tm_facets(), which leads to this
What I would want is for the labels "TRUE" and "FALSE" to disappear, and have the exclave in its own bounding box but inside the main map, slightly enlarged. I envision something similar to how many US maps handle Hawaii or many French maps handle the overseas territories
