I’ve posted before on this and I clearly didn’t know what I was doing. I still don’t really know what I’m doing but I now have some pretty pictures and that’s all anybody really wants. In this post I’m going to import a postcode shapefile from the OS, plot the postcodes in R, find the neighbours of each postcode and convert the data into a network graph. Github repository here.
After my last post on the ONS data structure this post is the first of a few on using that structure and some other public data, mostly UK government data, and mapping it using R. This first post is about getting shapefiles from various locations, loading them into R and plotting them.
I have been looking through the ONS geographic data on their Geo Portal and there are acronyms and variables everywhere so I thought it best to understand what they all mean. Whenever I refer to the output areas and super output areas I’m referring to the ones as at the 2011 census in England and Wales.
