GET DIRECTIONS

This is a one-day workshop on visualising data with R and ggplot.

R is an excellent tool for wrestling data into useable shapes for visualising, but it has a steep initial learning curve with a lot of pitfalls along the way. This workshop aims to help you hit the ground running as painlessly as possible, providing a basis for creating the visualisations you want.

You will be introduced to some of the standard ways of using R to tidy, re-arrange and format data, and then how to put this data into graphic form using ggplot. We will look at a typical data preparation and visualisation workflow, using Land Registry house price data as an example. The aim of the day is to make the underlying principles of tidy data and ggplot as clear as possible, so that you can make full use of its flexibility in deciding how to visualise your own data.

As well as learning the technical skills required to prepare data and visualise it, we will also look at the difference between visualisation for communication (e.g. in journal articles) and the vital role visualisation can play in deepening your own insight into data (including how programming choices differ for these two).

The course will assume you know the basics of Rstudio and R's data types. If you don't know these but still want to apply, a short self-learning document (3 to 4 hours) built especially to lead into this course can be provided.
