Even experienced data scientists who’ve been working with R for years are still learning new things, because the language itself is evolving, and new packages make new things possible all the time. R is an increasingly popular programming language, particularly in the world of data analysis Top 15 Data Analysis Tools For Managing Data Like A Pro and data science. Learning R can be a frustrating challenge if you’re not sure how to approach it. And although you’ll be building your own project, you won’t be working alone. You’ll still be referring to resources for help and learning new techniques and approaches as you work.
Data science is a fast-growing field with high average salaries . The online R community is one of the friendliest and most inclusive of all programming communities. You struggle through some of the boring stuff with no idea how it relates to the thing you actually want to do. The progress I have made since starting to use codecademy is immense! I can study for short periods or long periods at my own convenience – mostly late in the evenings.
Reviews from learners
The chapter on Graphics for communication is a great resource for making graphics look more professional. Once you’ve got enough syntax under your belt, you’re ready to move on to structured projects more independently. Projects are a great way to learn, because they let you apply what you’ve https://cryptominer.services/ already learned while generally also challenging you to learn new things and solve problems as you go. Plus, building projects will help you put together a portfolio you can show to future employers later down the line. Nobody signs up to learn a programming language because they love syntax.
If you’ve struggled to learn R or another programming language in the past, you’re definitely not alone. And it’s not a failure on your part, or some inherent problem with the language. You probably don’t want to dive into totally unique projects just yet. Instead look for structured projects until you can build up a bit more experience and raise your comfort level.

Project Blood Transfusion Analysis In this project we will be using statistical techniques to make statements and draw conclusions about a blood tranfusion company’s userbase. Learn to use R or manually calculate the mean, median, and mode of real-world datasets. Learn the basics of aggregate functions in R with dplyr, which let us calculate quantities that describe groups of data. Learn how to organize and modify data in R using data frames and dplyr. Learn how to use R and start working with data in this introductory course.
For these reasons, we find it most effective to teach a mix of base R and tidyverse methods in our introductory R courses. Nowadays, R is easier to learn than ever thanks to the tidyverse collection of packages. The tidyverse is a collection of powerful tools for accessing, cleaning, manipulating, analyzing, and visualizing data with R. This Dataquest tutorial provides a great introduction to the tidyverse. Syntax is a programming language is even more important than syntax in human language.
Ready to level up your R skills?
This list is just the tip of the iceberg — thousands and thousands of companies all across the globe hire people with R skills, and R is very in demand in academia and government, as well. Even from this short list, it’s clear that someone with R skills could work in almost any industry they wanted. The RStudio integrated development environment is a powerful tool for programming with R because all of your code, results, and visualizations are together in one place. With RStudio Cloud you can program in R using RStudio using your web browser. The R tidyverse ecosystem makes all sorts of everyday data science tasks very straightforward.
Think of the projects like a series of steps — each one should set the bar a little higher, and be a little more challenging than the one before. Perform Statistical Analysis with Tidymodels – a series of more advanced articles using tidymodels for statistical analysis. You analyze a series of interesting datasets ranging from CIA documents to WNBA player stats.
It’s the mountain of boring coding syntax and dry practice problems you’re generally asked to work through before you can get to the good stuff — the stuff you actually want to do. Don’t just watch or read about someone else coding — write your own code live in our online, interactive platform. You’ll even get AI-driven recommendations on what you need to review to help keep you on track.
You can always refer to a variety of resources for learning and double-checking syntax if you get stuck later. But your goal should be to spend a couple of weeks on this phase, at most. R is an open-source programming language designed for data science and statistics. It’s a powerful tool for working with data, and its documentation and supportive community offer helpful resources for new programmers. But to have a complete understanding of tidyverse tools, you’ll need to understand some base R syntax and have an understanding of data types in R.

Read the news and look for interesting stories that might have available data you could dig into for a project. Twitter — It may be surprising to learn, but Twitter is an excellent resource getting help on R-related issues. Twitter is also a great resource for R-related news and updates from the world’s leading R practitioners. The R community on Twitter is centralized around the #rstats hashtag. TidyTuesday – A semi-structured, weekly social data project in R where budding r practitioners clean, wrangle, tidy, and plot a new dataset every Tuesday. R for Data Science – by Hadley Wickham and Garrett Grolemund is an excellent R resource with motivating and challenging exercises.
- Learn to use R or manually calculate the mean, median, and mode of real-world datasets.
- R is an increasingly popular programming language, particularly in the world of data analysis and data science.
- Yet many learning resources, from textbooks to online courses, are written with the idea that students need to master all of the key areas of R syntax before they can do any real work with it.

R is often used for statistical computing and graphical presentation to analyze and visualize data. The average salary for a data scientist is pretty similar — $121,000 according to Indeed.com as of April 2021. Learning R is definitely a challenge even if you take this approach. But if you can find the right motivation and keep yourself engaged with cool projects, I think anybody can reach a high level of proficiency.

Machine Learning
Staying motivated to keep learning is one of the biggest challenges. Go to meetups or hook up with other R coders online and join a project that’s already underway. Create Robust Models with Tidymodels – build and train predictive models with this series of projects.
Is R coding hard to learn?
R is known for being hard to learn. This is in large part because R is so different from many programming languages. The syntax of R, unlike languages like Python, is very difficult to read. Basic operations like selecting, naming, and renaming variables are more confusing in R than they are in other languages.
You try to start learning and are immediately led to this huge wall of complicated, boring stuff. Usually, it’s the result of a mismatch between what’s motivating you to learn and how you’re actually learning. Learn the basics of R Syntax and jumpstart your journey into data analysis.
This is difficult to answer, because most people with R skills work in research or data science, and they have other technical skills like SQL, too. Ziprecruiter lists the average R developer salary as $130,000 in the US . Learning R can certainly be challenging, and you’re likely to have frustrating moments.
You can do a lot with just data visualization, for example, but that doesn’t mean you should build 20 projects in a row that only use your data visualization skills. Each project should be a little tougher and a little more complex than the previous one. Each project should challenge you to learn something you didn’t know before. As with the structured projects, these projects should be guided by the answers you came up with in step 1.
How long does it take to learn R?
R is considered one of the more difficult programming languages to learn due to how different its syntax is from other languages like Python and its extensive set of commands. It takes most learners without prior coding experience roughly four to six weeks to learn R.
R is a popular and flexible language that’s used professionally in a wide variety of contexts. We teach R for data analysis and machine learning, for example, but if you wanted to apply your R skills in another area, R is used in finance, academia, and business, just to name a few. The downside to learning for free is that to learn what you want, you’ll probably need to patch together a bunch of different free resources.
