Visualisation

25 June 2019, Bandwidth Barn, Woodstock, Cape Town

Objectives

Being able to communicate the results of an analysis is as important as doing the analysis itself. In this course you’ll learn how to use two R packages (ggplot2 and plotly) to create effective, visually pleasing and reproducible visualisations.

Outcomes

Participants will be able to create static and animated visualisations with ggplot2 and interactive visualisations using plotly. They will also be able to customise the presentation characteristics of these visualisations.

Who should attend?

The course is aimed at students, academics and professionals who need to visualise data. It’s assumed that participants already have some familiarity with R.

Course Content

The ggplot2 package has become the de facto standard for making plots in R. It’s possible to quickly put together a simple plot for exploratory purposes. However, with a bit of effort such a plot can be transformed into a work of art.

Requirements

Participants are assumed to have prior exposure to R, or at least to programming of some variety. Some familiarity with HTML and CSS will be an advantage but not mandatory. We’ll be using an online development environment. This means that you can focus on learning without having to worry about solving technical problems.

Interactive course material

Our training emphasises practical skills. So, although you’ll be learning concepts and theory, you’ll see how everything is applied in the real world as we work through examples and exercises based on real datasets.

We like questions!

Having a firm understanding of the course content will result in you being able to confidently apply your new skills. So, if at any point you’re unsure of something, just ask!
