Spatial data models and visualizations are important tools in the design of public policies. I provide below some links to tutorials about spatial modelling using R that I have found useful.
The first stop should be at the Spatial Data Science with R website. It contains a wealth of information organized in a straightforward way. My next suggestion is An Introduction to Spatial Econometrics in R website. A different version of the previous website is also available at R-Bloggers: An Introduction to Spatial Econometrics in R. There is also a tutorial by Luc Anselin: An Introduction to Spatial Regression Analysis in R.
Finally, there is a video made by econometricsacademy about Spatial Econometrics in R.
