R is built by statisticians for statistical analysis and other statistical purposes, being especially adept in working with data. R is a great addition to a data scientist’s toolbox and this article will delve deeper into the value R adds to IT and other processes.
An Introduction to R
R offers an open-source software environment, highly useful for statistical and graphical purposes. R is used by statisticians, researchers, scholars and data miners to facilitate the many functions that Data Science has to offer.
R is being maintained by the R Foundation for Statistical Computing. R is one of the most preferred choices when it comes to Data Science and analytical tasks. With an environment and language built primarily to power statistical analysis, working with massive amounts of data or datasets seems incredibly easy using R, especially when tasked with finding out predictive values or results.
R is a high-level programming language that does not require compiling and is based on S, its predecessor. R has seen a lot of development since the time of S-PLUS, the commercial version of S. However, most of the codes in S-PLUS are not altered and can still be observed being executed in R.
The official stable beta of R was first released by 2000. As of 2021, R is one of the most popular programming languages globally. R’s official software environments are GNU packages and are primarily written in R, Fortran and C.
Being written in R itself, it is a bit self-hosting in nature. R promotes object-oriented programming which has strong statistical computing standards and also supports the usage of Python, C++ or Fortran codes for manipulation and during computationally intensive tasks.
Advantages of Using R
R offers many advantages to data scientists and statisticians, here are some of the main benefits of using R.

Applications of R in Data Science
R has many applications in Data Science, it assists in powering many valuable components of Data Science and offers the benefits that modern Data Science has to offer to businesses and services. When talking about R in Data Science, it is extensively used in many fields to make services and processes more effective alongside data scientists and analysts to increase profit and use resources more efficiently.
Here are some of the important fields where R is used to power tasks that fall under Data Science and direct uses of R in Data Science.
1. Research and Development
R is highly used in R&D as it is great at working with massive amounts of data to promote analysis and breakthroughs in research. R helps find required values or predictive values from data which further can assist in development.
R can be useful for just research or development backed by research, as well as by assisting with valuable strategies and working with the variables to figure out the required course of action. It also helps reproduce the results later on.
2. Artificial Intelligence and Machine Learning
R helps data scientists’ work with datasets and training data by cleaning noise from data, acquiring the relevant data and by data mining when working with AI and ML. R also helps machines learn more effectively with advanced statistical support and predictive assistance. AI in general benefits from R’s huge resources and data-centric approach as well.
3. Production, Operations and Manufacturing
R helps with increasing the effectiveness and efficiency during production and manufacturing. R helps cut costs, increase profit and production within manufacturing or production processes by analysing production data and recommending more effective approaches to cut costs, increase efficiency, meet deadlines as well as ease operations.
R can help in dividing work among human assets by effectively assigning time and tasks to employees. This also helps in workspace management as well as human resources.
4. Business Analytics and Analysis
R helps both large and small businesses by conducting statistical analysis and analysing business trends to predict future challenges, opportunities of growth as well as help curb down immediate risks and loss.
R helps companies take better business decisions with predictive insights and visual representations through graphs by extracting valuable information from historic and business data. These are some of the most important and highly observed uses of R in Data Science.
R is one of the most preferred options for financial services and companies. R offers a huge range of statistical tools that power various financial functions such as risk measurement, credit-risk modelling and market analysis. R also helps produce interactive visualisations and graphs for financial reports. R is used alongside Hadoop to promise customer analysis and segmentation as well.
6. Medicine And Healthcare
R powers many functions in the fields of Medical Research, Genetics, Epidemiology, Bioinformatics and medicine. From empowering patient and disease analysis to chemical discoveries, R is extensively used to perform exploratory analysis during pre-clinical trials and for effectively working with drug-safety data. R also assists in analysing genomic data or for modelling epidemiological requirements.
7. Social Media and Advertising
From its uses in social media data mining to customer behaviour analysis, R has a wide range of uses in Social Media and advertising. Most of the data in social media are unstructured. Hence R is heavily used to target, extract and analyse this data to promote social media analytics for various functions like customer segmentation, audience targeting and building relational graphs, thus helping with effective marketing or advertising.
R helps forecast sales and further helps in suggesting and recommending products to customers through social media.
