This is the GitHub page for my post analysing Singapore's HDB resale flats transactions data, which you can find here.
There is only one R script file which you need (Data processing.R), which will work as long as you have the relevant data files in the same working directory in a folder called "Data". You can download all the raw data here, although all of this is also publicly available online on Data.gov.sg. I've also included some of the final processed data which I used for my analysis.
Raise an issue on GitHub or drop me a message on LinkedIn if you have any questions about the data or the analysis.
