Data analysis and analytics. Uncover insights and transform your organisation.

Welcome to the fascinating and exciting world of R programming. R is an elegant programming language specifically designed for data science, analytics, and statistics. This ‘R for Beginners’ course takes you through the fundamental skills and techniques required to use R. By the time you leave this focused R tutorial, you will be equipped with the required skills to embark on your own data science adventures. Even the most inexperienced participants will walk away from the course with newfound confidence using R for statistics and data analysis.

Bringing a combination of private, public, and academic professional experience, your instructor will guide you through this R tutorial, showing you step by step how to utilise R.

You’ll set up R and the excellent development environment RStudio, import external data, utilise add-in packages, process data for specific use, derive elementary summary statistics, and produce basic statistical visualisations.

We encourage you to use the CCE R Programming level self-assessment tool if you are unsure which course level to enrol in.

Aims

This course aims to provide a practical introduction to the R programming language. By the end of the day-long course, the user will be comfortable operating in the R environment, including importing external data, manipulating data for specific needs, and running summary statistics and visualisations.

Prerequisites

This course is designed with the beginner in mind. While some participants may have experience in other computer programming languages, no prior programming skills are required.

Delivery modes

• Face-to-face, presenter-taught training using your own device
• Online training via the platform Zoom

Face-to-face classes

These classes run in a classroom and you need to bring your own device with R and RStudio installed. You should ensure it is fully charged as access to power is limited. Please note that the University does not carry any responsibility for your lost, stolen, or damaged devices whilst on the University premises.

Online classes

You will need your own device with R and RStudio installed.

Delivery style

This course is taught through a series of concepts, examples, problem exercises, and in-class knowledge challenges. The material is presented so that participants of varying backgrounds, skills and abilities can all move together in a brisk, but comfortable learning pace. Utilising principles of productivity, efficiency, and time management, the course material and timeline is structured to optimise learning and value add.

Materials

A link to access and download the following online course materials is provided:

• PowerPoint notes with examples
• all code and script files used throughout the course
• ancillary hand-outs and learning aids.

Before the course

You will need your own device with R and RStudio installed. Both pieces of software are free to download:
