I am trying to create a chorpleth of Belgium in shiny (R) using this geojson file (github view). I am following the tutorial of rstudio to get the basics right. While doing this I encountered the following error while trying to use the geojsonio::geojson_read() function.
Error: Multiple incompatible geometries: wkbPolygon: 586; wkbGeometryCollection: 3
After some debugging I found that, indeed there are 3 GeometryCollections. However these collections are municipalities that have enclaves (multiple polygons for one municipality). One of which it the famous border craziness of Baarle Hertog/Baarle-Nassau. So both wkbPloygons and wkbGeometryCollection should be inside the same layer for plotting.
What would be the easiest way to accomplish this?
