Format of the course

This webpage contains material for the Introduction to R Course. The format of this course is as follows. There will be no lecture where we present the material. Instead, we will only give a brief presentation to point out some important information and features, and you will do most of the work by inferring the examples that have been laid out for you. In some topics where it would be appropriate to show you something on the computer screen, we have made some videos that are accessible from youtube. This way, you can rerun the video if you miss few bits of the illustration.

What is covered?

This course is designed to introduce the basics of R to students who
are not familiar with R yet. So, we do not cover some 'specialised'
analysis, but rather cover the basics and hopefully get them right. The
topics covered are outlined in this document. (Intro here)

Examples and Exercises (Assessment)

(See also some notes at the end of this section)

The way you will learn is by understanding what is going on in each of
the examples that we outlined for you, both in the videos and example
& exercise sheet.

The main document for examples and exercises are available here:

(Make sure you have plugged in your earphones to your computer to avoid making noise in the whole cluster)

Downloading and installing R

Open and close R, with access to help

Input and output

**Important!** It is very important that you run the examples one line at the time and understand what they do. There is potentially a difference between what you think R is doing and what it is actually doing based on the R codes. So, do not skip some of the lines.

Regarding assessment, you will need to answer some exercises that we
outlined for you in the above document. **Important!** Do not skip the exercises. Try to answer the exercises and ask your tutor to confirm whether you have done it correctly or not.
