## What Is R Programming?

R is a language and environment for statistical computing and graphics, according to R-Project.org. It is an open-source programming language that is often used as a tool for statistical analysis and data analysis.

The R environment is a set of software tools that work together to let you manipulate data, do calculations, and show graphs. The surrounding area has:

- A place to store and handle data that works well
- A group of operators for working with arrays, mostly matrices.
- A large, well-organized set of intermediate tools for data analysis that are easy to understand.
- Graphical tools for analyzing and showing data that can be used on-screen or in hard copy
- The programming language is well-developed, easy to use, and effective. It has user-defined recursive functions, loops, conditionals, and input and output.

There are three parts to the syntax of R:

- Variables, which hold information,
- Comments are used to make code easier to read.
- Keywords are special words that the compiler knows how to use.

## What’s R Programming Used For?

R is a popular programming language that is used by many programmers. It works best when used for

### 2. Banking

Banking industries use R for credit risk modeling and other types of risk analytics, just like financial institutions do.

The Mortgage Haircut Model is used a lot by banks because it lets them take over the property if the loan isn’t paid. Mortgage Haircut Modelling looks at the distribution of sales prices, the volatility of sales prices, and the expected shortfall. R is often used with proprietary tools like SAS for these tasks.

R is also used with Hadoop to making it easier to look at the quality of customers, how they are split up, and how long they stay with a company.

R is used by Bank of America to report on its finances. With R, the data scientists at BOA can look at financial losses and use the visualization tools that come with R.

**Uses Of R Programming in the** Banking** Sector :**

**ANZ**: The ANZ bank uses R to model credit risk and mortgage loss.**Bank of America:** Bank of America uses r to report on finances and determine how much money it has lost.

### 3. Healthcare

Genetics, Bioinformatics, Drug Discovery, and Epidemiology are all areas of medicine that use R a lot. With the help of R, these companies can crunch numbers and process information, which gives them a solid foundation for further data processing and analysis.

Most of the time, R is used to do pre-clinical trials and analyze drug-safety data. This is a more advanced type of processing, like drug discovery. It also gives its users a set of tools for exploratory data analysis and for making clear pictures of the data.

The Bioconductor package in R is also very popular because it has many functions for analyzing genomic data. In epidemiology, where data scientists study and try to predict how diseases will spread, R is also used for statistical modeling.
