R Programming Tutorial: A Quick Way to Learn R

The R programming language was created specifically for use in statistical analysis. So, if you’re a statistician needing a user-friendly and powerful tool, R is the programming language for you. Despite its origins in statistical analysis, R is now a robust and flexible program. Therefore, in this R Programming Tutorial, you will understand what makes R so potent and why you should study R programming to boost your professional standing.

Introduction 

The R Programming Tutorial is a comprehensive resource for programmers of all skill levels. If you’re interested in data analysis and visualisation, this tutorial covers everything from the fundamentals to the more advanced topics.

  • The R programming environment is a helpful tool for analysing data and creating visual representations of that data.
  • R’s function system makes it possible to write code modularly.
  • Each facet of R—its features, installation, IDE (Integrated Development Environment) Rstudio, variables, R data types, operations, if statement, R vector, data handling, graphics, statistical modelling, etc. are covered in this comprehensive tutorial.
  • The R programming language was named after the first letter of its two creators’ names (Ross Ihaka and Robert Gentleman).

How does R programming work?

“Robert Gentleman and Ross Ihaka at the University of Auckland in New Zealand made R. It is an interpreted programming language. Currently, R development is being handled by the R Programming Core Team. It’s a suite of programs for working with data in many forms, including statistical analysis, visualisation, reporting, and modelling. R is a programming language that uses S and lexical scoping semantics.

  • R’s function system allows it to write modular code that can do branching and looping.
  • R may be used to maximise productivity with programs written in C, C++,.Net, Python, and FORTRAN.
  • For data retrieval, cleansing, analysis, data visualisation in R, and presentation in the modern day, R is one of the most effective tools used by academics, data scientists, statisticians, and marketers.

Characteristics of the R language for computer programming

Data analysis is the primary focus of the computer language R. A lot of its strength comes from the fact that it is so novel and innovative. Vectors’ nomenclature is likely the most crucial. Using these R vectors lets us collect data in more than one step with just one statement.

The language R has the following capabilities:

  • It’s a well-developed programming language that’s easy to use and produces good results.
  • It’s a programme used for analysing data.
  • The language facilitates data manipulation in R.
  • It’s a simple, powerful language with built-in support for things like conditionals, loops, user-defined data types, and a wide range of input/output options.
  • For analysing data, it provides a unified and built-in collection of tools.
  • R provides a set of operators for performing various computations on arrays, lists, and vectors.
  • It has efficient means of data processing and storage.
  • An open-source programme that packs a punch and can be easily customised.
  • It offers flexible graphical methods that may be easily expanded upon.
  • It paves the way for various vector-based computations to be performed.
  • The programming language R is interpreted.

Why should you use R Programming?

Several programs are commercially available for analysing data. It takes a lot of time to become fluent in a new language. R and Python are both fantastic technologies available to data scientists. When we first start learning about data science, we won’t have enough time to understand it. Studying statistical modelling and algorithms is more valuable than learning a programming language. To calculate and convey our findings, we employ a programming language.

  • Data cleaning, extraction of features, feature selection, and importation are all crucial steps in data science.
  • The role of a data scientist is to analyse data, change it, and provide the most effective strategy.
  • R allows you to put into action the most cutting-edge machine-learning techniques.
  • With tools like Keras and TensorFlow, we can develop sophisticated ML strategies. A package exists in R to execute Xgboost.
  • When it comes to Kaggle competitions, Xgboost is among the top algorithms.
  • R can interact with and potentially call other languages like Python, Java, and C++.
  • R may also be used for significant data analysis.
  • R can be linked to various database management systems, including Spark and Hadoop.

In a nutshell, R is an excellent instrument for data analysis and exploration. R is used to do the in-depth analysis, which includes clustering, correlating, and reducing the data.

Uses of the R programming language

R is a state-of-the-art tool with many potential uses. It is already used in the financial world for online retail, banking, and financial services. Data visualisation in R helps with its application in various fields. 

The R programming language has several practical applications, including:

Finance

R has become the go-to language for data science in the financial industry. Programming in R gives you access to a powerful statistical package that can do all the critical financial tasks.

Banking

R is used in the banking industry for credit risk modelling and other risk analytics, much like in the financial sector.

Healthcare

R helps healthcare organisations handle information and crunch data, laying the groundwork for data analysis and processing in several fields, including genetics, informatics, drug development, and epidemiology.

E-commerce

R is helpful for the e-commerce industry because it can handle the many types of structured and unstructured data that these businesses generate and the many different types of data stores they use, such as databases and spreadsheets (SQL and NoSQL).

Communication Networks

Some of R’s most popular statistical methods are sentiment analysis and other types of social network data analysis. Social media provides a great learning ground for those new to Data Science.

Prerequisites of learning R programming

With the help of the R programming language, data can be analysed statistically and shown in graphs. Accordingly, we need to be familiar with the mathematical theory of statistics. We must know how to program and understand the diagrams used to depict data.

Students who want to learn more about implementing data analysis projects will find this R language tutorial useful. This tutorial will teach you everything you need to know to start with R and analyse data.
