This page is part of a series of blog posts written in preparation of a presentation at the FOSS4G Conference in Brussels (25 October 2018).
Now that you have loaded the file Belgium2018.json into R (see instructions here) you may want to create a thematic map.
Please proceed to the R code below to see how to create this map in French or in Dutch.
tmap
To create the thematic maps you will use the library tmap
.
The package tmap
on CRAN:
https://CRAN.R-project.org/package=tmap
If the package is not yet installed, you can install it with the following command:
install.packages("tmap")
Using the function qtm()
you can quickly create a thematic map. And if you use the column NAME_REG_FRE to color the municipaliteis, the French region names will appear in the legend:
library(tmap)
qtm(shp = BE_Municipalities2018,
title = "La division de la Belgique en régions",
fill = "NAME_REG_FRE",
fill.title = "2018\nRégion",
fill.palette =
palette(c("#000000", "#FDDA24", "#EF3340")),
borders = "grey",
format = "NLD_wide")
Using the function qtm()
you can quickly create a thematic map. And if you use the column NAME_REG_DUT to color the municipaliteis, the Dutch region names will appear in the legend:
library(tmap)
qtm(shp = BE_Municipalities2018,
title = "Regionale indeling",
fill = "NAME_REG_DUT",
fill.title = "België - 2018\nRegio",
fill.palette =
palette(c("#000000", "#FDDA24", "#EF3340")),
borders = "grey",
format = "NLD_wide")
