The growing technological developments have made programming a critical career skill. Most things that we see and use in our daily lives are somehow related to technology, which is why many students want to learn computer programming languages. So, today we are here to tell you how to learn R programming in 2022.
If you follow our tips to learn R programming, you can surely learn it with ease. R language will not only help you to get a job in the IT industry, but it will also make you eligible for other opportunities where a large set of data is used for analytics-based solutions.
Before knowing how to learn R programming, let’s see a basic introduction of R.
Introduction To R Programming
R is an open-source, extensible programming language and free analytic software. Ross Ihaka and Robert Gentleman developed it in the year 1993. R is very popular among data miners and statisticians. It includes a large catalog of graphical and statistical methods.
Many R libraries are developed with R. However, Fortran, C, and C++ are preferred for big computational tasks. Several surveys, polls, scholarly literature databases confirm a significant enhancement in R’s popularity. Various major companies like Google, Facebook, Wipro, Uber, Bing, Accenture, and Airbnb use the R programming language for statistical analysis.
R software is available freely under the GNU General Public License. R has a CLI(command-line interface), yet it supports multiple third-party GUI(graphical user interfaces), i.e., RStudio, Jupyter, notebook interface, etc.
Applications of R Programming
R is a very powerful and widely used language. It is the 1st choice of several researchers and data scientists. The use of R programming is not limited to any particular sector. Instead, it can be used in several different industries. Some of the primary applications of the R programming language are as follows-
- Healthcare: Pre-clinical trials and Analysis of drug-safety
- Banking: Credit risk modeling and other risk analytics
- Finance: Stock-market movement and prediction of share prices
- E-Commerce: User experience improvement, finance, and marketing strategies.
- Social Media: Unstructured data analysis- mainly comments for understanding the sentiments of users.
- Manufacturing: Customer feedback for improvements in products and deciding manufacturing requirements.
Can You learn R on your own?
Yes, you can learn R by yourself. It is absolutely possible. R is a high-level interpreted language and is very simple to learn. You can either watch the free tutorial videos on Youtube or buy paid courses to kickstart your R programming learning.
Many students start their R programming learning with no prior coding expertise and go on to work as data scientists, data analysts, and data engineers. R is a wonderful language for beginners to learn because it doesn’t require any prior programming knowledge.
Moreover, there are hundreds of free, high-quality online courses available, where you can enrol for free, learn at your own pace, practice and comprehend R, and receive a certificate of completion!
Thanks to the tidyverse collection of packages, learning R is now easier than ever. The tidyverse is a set of R-based tools for data access, manipulation, cleaning, analysis, and visualization.
How To Learn R Programming?
Learning a programming language can be very difficult without proper planning and the right approach. Therefore, to make R language easy for you, we are going to tell you the best tips for learning R programming.
You can follow these tips and share them with your friends who want to know how to learn R programming.
Understand the Basics
It is the first step to learning any programming language. For starting to code with R, you should know the fundamentals of R programming. If you become familiar with the fundamentals, it will become easy for you to grasp advanced concepts.
You can watch online videos, read blogs and books, R documentation to know the basics of R.
Code By Hand
Once you become familiar with the basics, you can try writing programs by hand. It is the second and very effective step to learning R programming. You can use a whiteboard or paper to write simple programs by hand.
Although it takes more time and you can’t run a handwritten code in midway, it will improve your caution and precision in programming. You will become more confident for technical interviews and college exams where the ultimate goal is to test the programmer’s proficiency.
Create Simple Programs
Now, it’s time to do some programming on the computer. Try to make simple programs in the beginning. It will enhance your practical knowledge and confidence in R programming.
Practice is the key to learning any programming language. Simply reading, listening, and watching is not enough for learning R programming.
You have to practice daily to grasp the advanced understanding of R programming. So, practice as much as you can. The more you practice, the more you learn.
Ask For Help
It is very common to get stuck in between programming. So, asking for help is the next step to learning R programming. You can request online community support for solving your R programming problems.
There are thousands of R programming experts who are ready to help you. And remember, every R programming expert had been in your shoes, so don’t ever think twice before asking for help.
Now, when you know the R’s basics, implementation, and debugging, it is the right time for you to build some projects. Try to make smaller and simpler projects in the beginning.
And, when you start to feel confident, you can develop more significant projects. Some of the popular R language projects ideas for students are-
- Uber Data Analysis
- Sentiment Analysis
- Customer Segmentation
- Speech Emotion Recognition
- Movie Recommendation System
- Wine Preference Prediction
- Credit Card Fraud Detection
- Predict Churn for a Telecom Company
Now when you are able to develop projects by yourself, you are ready to help others. This will help you to explore more in R programming. Solving programming problems is necessary for consistent learning. The more problems you solve, the more you learn.
Is R worth learning in 2022?
R is a wonderful programming language that’s widely used in data science. However, you may be thinking, “Why should you learn R in 2022?” Whether it is worth learning or not. The answer is yes, R is completely worth learning for anyone who wants to build a career as a data scientist, data engineer, data analyst, etc.
It is a fantastic programming language to learn, and having R in your programming language skills could help you qualify for more positions as a data scientist. If that isn’t convincing enough, consider the following reasons why R is still worth learning.
You’ll always be able to get jobs that require R as their primary programming language. But, if you’re fortunate enough to have everything covered, work on honing your skills and learning python a little more. That way, you can be certain that you will always meet the standards, no matter what they are.
Moreover, most things you learn in R have Python equivalents, which you can find by searching for “X equivalent in Python” and vice versa. You will always be able to find solutions. Therefore, R is a great language to learn and start your career with.
Hopefully, you got the best answer to how to learn R programming. Apart from these tips, the most important thing for learning R programming is confidence. During the learning phase, you may fail repeatedly and get frustrated. Always remember, failure is just another step towards success. So, you should keep faith in yourself and have some patience.
