The programming language R continues to gain popularity. According to TIOBE, a software QA automation company that ranks programming languages based on how often they’re searched for online, R is catching up with Python, fast. As of August 2020, R is the 8th most popular programming language (its highest position ever — in 2019, for example, it was the 20th most popular), ahead of SQL, MATLAB, and Swift (Python is third most popular, after C and Java).

So, why R? One potential reason is that universities and research institutes are turning away from commercial packages like Stata in favor of open source languages like R and Python. Another is the increase in statistical computing and data mining being used to search for a COVID-19 vaccine. The sudden interest in R could also have something to do with the fact that R is reproducible and cross-platform compatible, can connect with other languages, and has a vast user base in both academia and business (Facebook, Google, and Bank of America all use R).

The only problem? R has a reputation for being difficult to learn. As the consultant, John D. Cook said, “I have written software professionally in perhaps a dozen programming languages, and the hardest language for me to learn has been R. The language is actually fairly simple, but it is unconventional.” Luckily, with the right R programming language course, you can go from beginner to a competent R programmer in no time. Below we’ve compiled a list of the nine best R online courses that’ll help future data scientists and data analysts get to grips with one of the most powerful programming languages for statistical computing and data visualization.

Without further ado, these are the best R courses:

- Best Overall: R Programmer (DataCamp)

## Data Science: R Basics (edX)

Become a certified data scientist by taking Data Science: R Basics, the first course in HarvardX’s Professional Certificate Program in Data Science.

Visit Site

- Offered by Harvard University
- Includes a free textbook
- Assignments provided via DataCamp
- Prior experience not required
- You can audit course content for free

The Data Science: R Basics course is the first part of HarvardX’s (free online courses offered by the Harvard University of edX) Professional Certificate Program in Data Science (which consists of nine courses).

At the end of this course, students should know how to import R packages and then use them in R scripts. They should also be able to work with vectors, sort data, filter data based on condition, and apply general programming features like “for loop” commands.

Course material is taught by Rafael Irizarry, Professor of Biostatistics at Harvard University, via short video lectures and assessments. Course assignments are offered via DataCamp’s interactive web-based programming interface. At the end of each section, there’s a final assessment that tests your knowledge of all the topics you’ve just covered. The course also comes with a free textbook.

Note that this course doesn’t delve into more advanced topics such as probability, regression, and machine learning (these are covered later in the series).

Most students can expect to complete the course in about eight weeks, as long as they spend one to two hours each week learning. That being said, if you have some programming experience, you might finish it much quicker. However, prior experience isn’t necessary.

You can audit this course for free, but you won’t get graded assignments, nor will you receive R certification at the end of the course.

Taking a course designed by Harvard University lecturers is always worthwhile. EdX’s R Basics is no exception and is the first course in HarvardX’s Professional Certificate Program in Data Science that will teach you the basics of using R and coding in R.

## R Tutorial (Tutorialspoint)

Don’t want to spend hours trying to figure out which one of the numerous R online classes is compatible with your level of understanding of R? The R Tutorial available on Tutorialspoint is great for jumping directly into the topic you want to learn.

Visit Site

- Free
- No prerequisites
- Great as a reference
- Available in PDF

- Text-based

As the name probably makes it quite clear, Tutorialspoint is a site dedicated to sharing knowledge about various programming languages, including R.

The R Tutorial is split into four main sections. The first section (‘R Tutorial’) covers things like the history of R, data types, variables, loops, matrices, factors, and data frames. In contrast, the second section (‘R Data Interfaces’) teaches you how to read CSV files, Excel files, XML files, Web Data, and similar. The third section (‘R Charts and Graphs) is all about charts and graphs, including pie charts, histograms, and line graphs. Finally, the fourth section (‘R Statistics Examples’) goes over concepts such as linear regression, time series analysis, and decision tree.

There’s also a section dedicated to useful resources (like a quick guide to R) and selected reading (including ‘Developer’s Best Practices’ and ‘Computer Glossary.’)

However, bear in mind that all of the free content is text-based (the site does have R video tutorials, but you’ll need to pay for those). As such, even though there are no prerequisites (other than knowledge of computer programming terminologies) to taking this course, it mightn’t be the best place for learning R from scratch. Instead, many people use the site as a reference.

Tutorialspoint’s R Tutorial is an excellent beginner reference text and is also useful for recalling bits of information you might have forgotten. Best of all, it’s completely free and comes with helpful resources, like a list of questions you might be asked during an interview for a data scientist position.
