Course information

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

R is an elegant programming language specifically designed for data science, analytics, and statistics. This Intermediate R Programming course guides participants through more advanced data processing, analytics, and visualisation techniques in R.

By the time you leave our course, you will have a set of data manipulation tools, including tidyverse, dplyr, and ggplot at your fingertips. These tools will help you prepare data for more advanced analytics and modelling. You will also learn to perform statistical regression modelling and hypothesis testing on data sets to uncover valuable patterns and insights. Finally, we will cover programming techniques unique to the R, helping you learn to write optimised and efficient code.

Bringing a combination of private, public, and academic professional experience, your instructor will guide you through Intermediate R, showing you step by step how to utilise R for sophisticated data analytics.

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

*You are not required to have taken the introductory course – R Programming Course: Introduction. However, you should be familiar with the learning outcomes listed.

Aims

This course aims to provide an in-depth, more advanced coverage of data processing and analysis in the R programming environment. By the end of the day, you should be comfortable processing, manipulating and preparing data for further analysis, visualising data using elegant graphics, computing regression statistics and confidence intervals, and efficiently programming in the R environment.

Outcomes

By the end of this course, you should be able to:

• prepare data
  • work with advanced R data types like data.frames and lists
  • subset data for deep queries
  • use the tidyverse suite of packages for data science
  • utilise the data.table package for faster processing
• perform analytics and statistical inference
  • explore data using ggplot visualisations
  • build and analyse linear regression models
  • run hypothesis tests and confidence intervals
  • produce advanced data visualisations with the ggplot package
• program efficiently in R
  • optimise RStudio
  • develop for/while loops for data flows
  • vectorise R data frames
  • write efficient and optimised R code
  • utilise custom functions for faster processing.

Intended audience

Business professionals, managers, IT knowledge workers and lifelong learners looking for a deeper knowledge of data processing and analytics in R will find Intermediate R Programming helpful.

Prerequisites

This course is aimed at professionals with some basic exposure to the R programming language. Participants of this course should be familiar with the learning outcomes of the R Programming Course: Introduction.

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 at a brisk, but comfortable learning pace.

Materials

A link to access and download the following online course materials (using Dropbox) 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:

• Download R here
• Download RStudio here (the free version will suffice)
