Ubuntu – Installing R and RGedit Plugin
R is a fantastic bit of software which I have been using on and off for a number of years since I gave up on SAS due to their (free for academics) annoying licenses and limited support for the things I wanted to do – R is infinitely flexible and totally free. Installing R on Ubuntu is very easy: ?Download code.txt1 sudo apt-get install r-base ...

Extracting all Crime Data for England and Wales using R and MYSQL
Last week I started creating some data extraction code for the new England and Wales crime maps website using the R software / language. Although there is an API, a more efficient way of accessing all of the data (and without causing stress to their API server) is to download the CSV files located here for each police force. To download these man...

How Scenic is the HS2 Route?
It is fairly clear from the duration between this and my last post that various other things have been getting in the way of updates. Anyway, I shall try and post a few updates on news and things I have been working on recently in the coming weeks before getting back to regular posting! Back in January I had a student working on a dissertation ab...

Installing Routino under OSX
Routino is a set of libraries that enable road based route calculations to be conducted over OpenStreetMap data. I have been using them extensively over the past six months for a project looking at CO2 emissions and the commute to school. Although Routino was designed to run under Linux, it can also be compiled and installed under OSX (sorry no w...

Using R with Routino to provide road network paths between random Tweets and an iconic Smiths landmark
A couple of days ago I posted how you can go about installing Routino on OSX; and now I have just finished writing a quick post over on my Rpubs blog about how you go about using it from within R. I also wanted to know a bit more about how R and Twitter play together so this is woven in too. Oh, and I was also listening to the Smiths back catalog...

Creating 2011 Census Output Area Change Maps Using R
The 2001 Census used a different set of Output Areas (OA) than the current 2011 boundaries; reflecting changes in the spatial distribution of the underlying population. For example, if an area has become more heavily populated since 2001, it makes sense that a previous OA might be split into multiple new segments. The ONS have provided both the�...

2011 Census Open Atlas Project
This month has seen the release of the 2011 census data for England and Wales at Output Area Level. This offers the possibility to map various attributes about people and places for very small geographic areas. Output Areas represent the most detailed geography for which Census data are released and are the building blocks for many popular prod...

Census Atlas Japan
The 2011 Census Open Atlas project has been put on hold recently as various other research projects have intervened – more on these soon. However, over the summer Chris Brunsdon and I have taken a research trip to Ritsumeikan University (Japan) where we visited Keiji Yano and Tomoki Nakaya. As part of this trip I began developing a cens...

Census Open Atlas Project Version Two
This time last year I published the first version of the 2011 Census Open Atlas which comprised Output Area Level census maps for each local authority district. This turned out to be quite a popular project, and I have also extended this to Japan. The methods used to construct the atlases have now been refined, so each atlas is built from a ser...

The data are derived from multiple sources including: the 2011 Census, Department for Transport estimates and the results of a research project looking at carbon dioxide emissions linked to the school co...
