R Programming for Data Science: Introduction



Overview

R is a popular and free programming language. It is easy to install and works on common platforms such as Windows, Linux and Mac. Even if you have limited or no computer programming experience, R is easy to learn.

Its applications span various areas such as statistical significance testing, data analysis and visualisations, data processing, manipulation and summarisation. An example is the fact that it is fairly easy to perform MS Excel, or SQL-like operations with R. In addition, R is a good choice for machine/deep learning, image analysis and processing and much more.

During the course you will learn the basics of the popular R programming language and how to use it to manipulate data and perform excel-like operations. 

This course begins with the very basics of R and its syntax and control statements, and gradually builds up to cover lots of useful functionalities and data manipulation. For example, the course covers control statements and instructions related to decision making and iterations as well as various types of data structures and functions. After this, you will learn how to use R to apply several common data processing and manipulation operations.

The course is designed in such a way that people with minimal or no computer programming experience can use it as a foundation to learn more advanced R topics or transfer their skills to other programming languages.

Certification

Credit Application Transfer Scheme (CATS) points 

To earn credit (CATS points) for your course you will need to register and pay an additional £30 fee for each course you enrol on. You can do this by ticking the relevant box at the bottom of the enrolment form or when enrolling online. If you do not register when you enrol, you have up until the course start date to register and pay the £30 fee. 

See more information on CATS point

Coursework is an integral part of all online courses and everyone enrolled will be expected to do coursework, but only those who have registered for credit will be awarded CATS points for completing work at the required standard. If you are enrolled on the Certificate of Higher Education, you need to indicate this on the enrolment form but there is no additional registration fee. 

 

Digital credentials

All students who pass their final assignment, whether registered for credit or not, will be eligible for a digital Certificate of Completion. Upon successful completion, you will receive a link to download a University of Oxford digital certificate. Information on how to access this digital certificate will be emailed to you after the end of the course. The certificate will show your name, the course title and the dates of the course you attended. You will be able to download your certificate or share it on social media if you choose to do so. 

Please note that assignments are not graded but are marked either pass or fail.

He is an experienced scientific software developer and data analyst; over the last few years he has been using R and Python as his preferred programming languages. Also, he has been involved in several projects spanning a variety of fields such as bioinformatics, textual/image/video data analysis, drug discovery, omics data analysis and computer network security. He has taught at multiple universities in the UK and has worked as a software engineer in different roles.

Course aims

An introductory overview of the R programming language is covered in this course. Students will learn the basics of R and move on gradually to data processing and performing excel-like operations on tabular data.

Course objectives:

  • To introduce programming with R.
  • To introduce how to read data from files.
  • To introduce how to perform excel-like operations with R.

Teaching methods

This is an online course so all lectures will be pre-recorded. Students will be given access to any material used in the lectures such as slides and R scripts. Weekly online interactive sessions complement the recordings.

Learning outcomes

By the end of the course students will be expected to:

  • understand R syntax, basic control flow and program design;
  • understand R data structures and how/when to use them;
  • understand how to perform Excel-like operations with R.

After attending this course, students will know:

  • foundational programming concepts such as variables, iterative statements, conditionals, functions and data structures;
  • how to read and write files, how to generate basic plots and visualisations and how/when to use data structures;
  • how to perform several excel-like operations such as sorting and filtering data, joining tables and much more.

Assessment methods

The assessment will be a set of ten questions that will enable students to demonstrate an understanding of the material discussed during each week of the course.

Coursework is an integral part of all weekly classes and everyone enrolled will be expected to do coursework in order to benefit fully from the course. Only those who have registered for credit will be awarded CATS points for completing work the required standard.

Students must submit a completed Declaration of Authorship form at the end of term when submitting your final piece of work. CATS points cannot be awarded without the aforementioned form - Declaration of Authorship form

 

Application

We will close for enrolments 14 days prior to the start date to allow us to complete the course set up. We will email you at that time (14 days before the course begins) with further information and joining instructions. As always, students will want to check spam and junk folders during this period to ensure that these emails are received.

To earn credit (CATS points) for your course you will need to register and pay an additional £30 fee per course. You can do this by ticking the relevant box at the bottom of the enrolment form or when enrolling online.

Please use the 'Book' or 'Apply' button on this page. Alternatively, please complete an Enrolment Form (Word) or Enrolment Form (Pdf)

Level and demands

The Department's Weekly Classes are taught at FHEQ Level 4, i.e. first year undergraduate level, and you will be expected to engage in a significant amount of private study in preparation for the classes. This may take the form, for instance, of reading and analysing set texts, responding to questions or tasks, or preparing work to present in class.

Credit Accumulation and Transfer Scheme (CATS)

To earn credit (CATS points) you will need to register and pay an additional £30 fee per course. You can do this by ticking the relevant box at the bottom of the enrolment form or when enrolling online. Students who register for CATS points will receive a Record of CATS points on successful completion of their course assessment.

Students who do not register for CATS points during the enrolment process can either register for CATS points prior to the start of their course or retrospectively from the January 1st after the current full academic year has been completed. If you are enrolled on the Certificate of Higher Education you need to indicate this on the enrolment form but there is no additional registration fee.
