Making thematic maps for Belgium

For people from Belgium working in R with spatial data, you can find excellent workshop material on creating thematic maps for Belgium at https://workshop.mhermans.net/thematic-maps-r/index.html. The workshop was given by Maarten Hermans from HIVA - Onderzoeksinstituut voor Arbeid en Samenleving.
The plots are heavily based on BelgiumMaps.Statbel - an R package from bnosac released 2 years ago (more info at http://www.bnosac.be/index.php/blog/55-belgiummaps-statbel-r-package-with-administrative-boundaries-of-belgium
