Hands-on Exercise 8A: Choropleth Mapping with R
1 Overview
This hands-on exercise covers Chapter 21: Choropleth Mapping with R.
As I took ISSS624 during the Nov term, this is just a refresher for me. I revised using my previous work.
Please refer to my previous work in this chapter: https://isss624-kjcpaas.netlify.app/hands-on_ex1/hands-on_ex1b
The notes I have here are more of additional learnings.
2 Reflections
During ISSS624, I worked with R for the first time so my learning was split towards learning R and learning about geospatial visualization with tmap.
During that class I was just following the code examples, reading the documentations a bit but I didn’t have an understanding of Grammar of Graphics.
The interface of tmap is also quite different to ggplot2, especially around themes that I already familiarized myself in,
This time around, I will try to improve on my previous work using the learnings from this class.
