Good Data Visualisation with R

In person 

This course will focus on developing practical skills for visualising data in R, primarily using the ggplot2 package. 

The first session offers an introduction to the ggplot2 package and a practical demonstration of the package. It focuses on topics such as: 

• Ggplot2 syntax 

• Basic plots with ggplot2 

• Deeper customisation of plots, including labels, colour maps, and re-sizing/re-positioning legends 

• Exporting plots 

   

The second session focusses on some principles for using data visualisation in research. A more freeform practical exercise with example data is then offered, and attendees can attempt to replicate and improve visualisations. This covers processes that include: 

• Different types of plots and when and where each might be best used 

• The pitfalls of misleading data visualisation 

• Introduction to some more advanced visualisation possibilities 

The course will ultimately help to develop a foundational understanding of Visualisation in R. Crucially, this will foster a familiarity with the principles of data visualisation and the capabilities of the software, allowing attendees to confidently apply these, or indeed seek out new concepts for their current and future research. 

This course will be taught by Rhys Davies and Alex Crest. 

After taking part in this event, you may decide that you need some further help in applying what you have learnt to your research. If so, you can book a Data Surgery meeting with one of our training fellows.

Level  

 Students must have a basic background in R. This includes, at least the basic data types in R, how to install and load packages, and how to use functions, pipes, and apply/map functions. It will be sufficient for students to have taken the Introduction to Programming with R and RStudio course.
