The popularity of the R programming language is increasing, especially in data science and analytics.

As it provides better data visualization techniques, R programming plays a crucial role in statistics.

However, learning this language could be frustrating if you do not have a clear path to approach it. In the past, you might have struggled a lot while learning R or any other language.

Trust me; you are not alone!

Don’t blame it on yourself entirely or the language; the issue might have been in your approach. The way you learn something has a massive hand in delivering the final result.

If you have a clear strategy of how and why you should learn a particular language, the chance of your being proficient in it amplifies. Similarly, if your goal and strategy do not align, you might get bored with the language and end up quitting it midway.

It is analogous to learning a spoken language.

So, when you are ready to learn R, get your motive clear in the first place, be it expanding your knowledge or finding a career in data science. Next, prepare a strategy and align it with your goal.

…And start learning.

In this article, I will talk about some good resources to learn the R programming language that will give you the right approach to making things easier.

But first things first,

What is the R Programming Language?

R is an open-source programming language for graphics and statistical computing.

It was developed in 1993 by Ross Ihaka & Robert Gentleman. It is similar to the programming language – S. You could say that R programming language is an implementation of S, combining lexical scoping semantics. The software is written majorly in C, R, and Fortran.

R offers a wide-ranging variety of both statistical and graphical techniques in addition to being highly extensible. It includes classical statistical testing, linear & non-linear modeling, time-series analysis, clustering, and classification.

One of R language’s major strengths is being effortless in producing a well-designed publication-quality plot, including mathematical formulae and symbols.

The capabilities of R

R is a kind of integrated suite consisting of software facilities you can use for calculation, graphical representation, and data manipulation.

It includes:

  • Effective storage and data handling facility
  • An integrated, coherent, and large collection of data analysis tools
  • A suit of various operators useful in calculating arrays in specific matrices
  • Simple, effective, and well-developed programming language with loops, conditionals, and user-defined variables
  • Graphical facilities to analyze data and display it on hardcopy or on-screen
  • R is capable of extension through packages. In fact, about 8 packages are supplied using R distribution, while more can be added with the CRAN site family.
  • Cross-platform interoperability
  • Instead of using a compiler, R uses an interpreter, which helps make code development easier.
  • It associates well with different databases and brings information from MS Access, Excel, MySQL, Oracle, SQLite, etc.
  • It integrates powerful tools for communicating reports in various forms such as HTML, XML, CSV, PDF, and interactive sites with R packages.
  • R packages come with diverse codes, features, and functions tailored for statistical modeling, data analysis, machine learning, visualization, data imports, and manipulation.

How does R assist in data analysis?

Data analysis using R takes place in a series of different steps:

  • Program or import: Programming with R or you can import data from databases and files into the R software environment
  • Transform: Data organization happens by transforming a column into a variable during a row into an observation. Observe your interests, create a new variable as a function of current variables, and discover observation statistics.
  • Visualization: Data representations in a graphical form to recognize trends, patterns, and data exceptions easily.
  • Models: These are complementary visualization tools such as computational or mathematical tools to answer observational questions.
  • Communication: Communicating results with others, right from visualization to modeling, with the help of easy-to-produce, print-quality plots to share with anyone in the world.

Who uses R and why?

R is trusted not only in academics but also by large companies, including Google, Facebook, Airbnb, Uber, and more. It is used in healthcare, consulting, government, insurance, energy, finance, media, almost everywhere. They use it for statistical inference, machine learning algorithms, and data analysis.

You see, the demand for R is in various sectors. In addition to this, data analysis is undoubtedly shaping present-day businesses. Even though there are plenty of tools available, R stands out. It’s because you may have:

  • Excel and PowerBI, but they lack modeling capability;
  • Python is great for AI and ML but does not have communication features;
  • SAS is good for statistical analysis but not free
  • Tableau is excellent for graphical representations, but it needs to do better in decision making and statistics.

However, R fills the gap by offering an excellent learning curve with a good balance of data implementation and analysis.

Hence, it makes sense to learn R for data manipulation and analysis and even become a data scientist.

And this is why data scientists use R to understand data, perform manipulation, make the best approach, and communicate with others through reports, dashboards, or web apps. In this way, a single platform performs all the work.

Now you know how R works and why you should go for it, but where to learn R?

Is it that difficult to learn?

If you asked me these questions a few years ago, I’d have said yes, it is a bit difficult due to its complex structure. But now, packages are introduced to overcome this issue, which has made data manipulation easier and intuitive, and graph creation is rather easy.

Packages like TensorFlow and Keras let you create high-end ML techniques; you can call Python, C++, and Java in R and connect with Hadoop or Spark. And R has evolved in terms of computational speed as well.

So, do you want to learn R?

I’m assuming a YES!
