Applications of R
We learned basic information about the R programming language and when and why it was created. Now let us discuss the applications of R in the real world and understand them in detail.
Research and Academics
R is utilized in research and academics as a statistical research tool. It is used for data evaluation, statistical modeling, and representing data. Researchers analyze and build models with the help of functions, including lme4.
R is likewise used for machine learning research and deep learning. Packages in R, like ggplot2 and plotly, help us represent the results of research findings.
Finance
Data Science is most widely used in the financial industry. The finance industry relies on R for portfolio optimization, risk analysis, and asset pricing.
Libraries in R simplify moving averages, auto-regression, time-series analysis, stock-market modeling, financial data mining, and downside risk assessment. This helps in better decision-making and produces good results. We can display the results of the analysis using high-quality candlestick charts, density, and drawdown plots.
Companies like American Express, Bajaj Allianz Insurance, JP Morgan, Standard Chartered, etc., use R.
Banking
Banking industries also use R for credit risk modeling, fraud detection, and other risk analytics. Packages, such as caret and randomForest, help develop credit scoring models and also help to identify fraud patterns.
R with Hadoop is used to analyze customer quality, types, etc. With the help of R, the data scientists at BOA(Bank Of America) study financial losses and represent data using many tools.
IT Sector
IT companies use R for analyzing data, machine learning, and software development. Agencies use R for business intelligence. They also offer these services to other businesses of different sizes.
IT companies use R's machine learning abilities to detect network breaches, filter spam, and make recommendations.
Big IT companies like Accenture, IBM, Infosys, Paytm, TCS, and Wipro use R.
E-Commerce
E-commerce goes beyond in its usage of data science. R helps by providing valuable insights into customer behavior, sales forecasting, and personalized marketing. E-commerce platforms use data analysis and representation tools to understand customer preferences and different markets. It also helps optimize pricing strategies. These results enhance customer experiences, improve storage management, and drive sales growth.
They use R to improve cross-product selling. When a customer buys a product, the site suggests extra products that complement their original order. These suggestions also work for products purchased by the customer in the past.
Social Media
Today, a lot of data is generated and regulated on social media. Therefore, data science is widely used in the social media industry. R is a tool used for social analytics. It helps companies get useful results from their social media data. Social media companies utilize R for analyzing behavior, sentiments, topics, and social networks. Companies can learn about customers' feelings by studying data, checking how people see their brand, and spotting new trends.
R is also used to analyze traffic, user sessions, and content. Organizations use it to improve users' suggestions based on their history, mood, and recent posts and content views.
Manufacturing
R helps the manufacturing industry by providing tools for process optimization, quality control, and predictive maintenance. Manufacturers can use statistical process control techniques in R software to ensure production quality by analyzing data.
Predictive modeling helps predict equipment failures, improves maintenance, and reduces the layoff period. Manufacturers can save money and improve production by studying their machines' data. Using this information, they can find and fix problems and improve things.
HealthCare
The healthcare sector uses R for data analysis in bioinformatics and medical research. It analyzes diseases, genetic sequences, drug-safety data, and drug/chemical combinations. Bioinformatics packages, such as Bioconductor, offer many tools for gene studies and finding biomarkers.
R helps show and display medical research results and information. It also supports epidemiological modeling, disease surveillance, and healthcare resource optimization.
According to Keaven Anderson (Executive Director of Late Stage Biostatistics, Merck)
"We use R for adaptive designs frequently because it's the fastest tool to explore designs that interest us. Off-the-shelf software gives you off-the-shelf options. Those are a good first-order approximation, but if you really want to nail down a design, R is going to be the fastest way to do that."
Governmental Use
Governments across the globe use R for various applications, such as economic modeling and policy analysis. This helps in decision-making. Statistical tools allow governments to analyze domestic data, track health scenarios in a country, and predict financial trends.
Data visualization packages enable the creation of interactive dashboards and report to help policymaking. Moreover, R is used in public health analysis, crime mapping, and transportation planning. R's open-source nature and active community make it an accessible tool for governmental agencies with limited resources.
Frequently Asked Questions
What is R programming language?
R is an open-source language, so we can contribute to its development. R was mainly designed for statistical computing and data analysis. It was created by Statisticians Ross Ihaka and Robert Gentleman at the University of Auckland in 1997.
How R helps e-commerce companies?
R helps E-commerce companies to understand customer behavior and product markets. It helps in optimizing pricing strategies. The machine-learning algorithms help us divide customers into groups and recommend products. These algorithms also help in sales forecasting. R helps cross-product selling by suggesting products based on their history.
What are the features of R?
R is an open-source language allowing everyone to contribute towards its development. It provides multiple packages and libraries for various uses. R is an object-oriented programming language, efficient in software development. Some other R features are compatible with numerous platforms, and no compiler is needed.
