R Programming - Intermediate Course - Hong Kong
Learn to use R for data analysis, instructor-led course.
R is a programming language specifically developed for the statistical analysis of data and for producing graphical output. We introduced the core concepts of R programming in our R Beginner course. This course, R Programming Intermediate, is the second in our R training course series and focuses on:
- data manipulation
- basic exploratory data analysis
- creating customised data visualisations
- basic modelling
An experienced trainer will guide you through exercises to practice writing R code, use a variety of different functions, produce graphical output and view the results. Read the full outline here.

Frequently Asked Questions
Course Introduction
Our R courses were designed by Tamara Shatar, who holds a PhD in Agricultural Data Science. She focused her extensive experience and skills in modelling using machine learning, simulation and other techniques to create a course with depth and applicability.
The course is consistently well reviewed by students.
"Great structure, material and manual. I have completed programming courses before but this one just made more sense! Looking forward to the Intermediate course." - R Intermediate Sydney.
What is R?
R is an open source and free programming language that was developed for statistical analysis and production of high-quality graphics. It has long been popular with statisticians and academics who make up part of the large active user community behind R. This community has contributed over 15,000 packages that extend the base functionality of R, making it easy to implement a vast range of techniques for data manipulation, analysis and visualization.
Is R compatible with Microsoft?
Microsoft have recognized the power of R and offer not only their own enhanced distribution of R, Microsoft R Open, but the ability to use R within Microsoft products and services such as Power BI, SQL Server / SQL Server Machine Learning Services and Visual Studio. Microsoft have also developed several packages, including the Microsoft Machine Learning Package for R. Check out R scripts in Power BI
What is Remote Training?
Remote training at Nexacu, means our team of experienced trainers will deliver your training virtually. With remote learning students can access our usual classroom training courses via video conferencing, ask questions, participate in discussion and share their screen with the trainer if they need help at any point in the course. Students have the same level of participation and access to the trainer as they would in classroom training sessions.
