What is R?

R is a programming language and software environment used for statistical computing and graphics. It is open source and free to use, and is widely used in academia, government, and industry.

What are some advantages of using R?

Some advantages of using R include its flexibility, powerful statistical and graphical capabilities, and large and active community of developers. It also has a large number of packages available for a wide range of tasks, and is highly customizable.

What is the difference between R and other statistical software such as SAS and SPSS?

R is open source and free to use, while SAS and SPSS are proprietary software that require a license. R also has a larger and more active community of developers, and is highly customizable. However, SAS and SPSS may have better performance and stability in certain situations.

What are packages in R?

Packages in R are collections of functions, data, and documentation that extend the capabilities of the base R system. They are typically created by developers and made available for others to use.

What is tidyverse in R?

Tidyverse is a collection of R packages designed for data science and data visualization. It includes packages such as ggplot2 for data visualization, dplyr for data manipulation, and tidyr for data tidying.

What is a data frame in R?

A data frame in R is a two-dimensional table-like data structure, with rows representing observations and columns representing variables. It is one of the most commonly used data structures in R, and is often used for data analysis and modeling.

What is a function in R?

A function in R is a block of code that performs a specific task and can be called from other parts of a program. Functions in R can have input parameters and return values, and are often used for tasks such as data manipulation, modeling, and visualization.

Snippet from Wikipedia: R (programming language)

R is a programming language for statistical computing and graphics supported by the R Core Team and the R Foundation for Statistical Computing. Created by statisticians Ross Ihaka and Robert Gentleman, R is used among data miners, bioinformaticians and statisticians for data analysis and developing statistical software. The core R language is augmented by a large number of extension packages containing reusable code and documentation.

According to user surveys and studies of scholarly literature databases, R is one of the most commonly used programming languages in data mining. As of AprilĀ 2023, R ranks 16th in the TIOBE index, a measure of programming language popularity, in which the language peaked in 8th place in August 2020.

The official R software environment is an open-source free software environment released as part of the GNU Project and available under the GNU General Public License. It is written primarily in C, Fortran, and R itself (partially self-hosting). Precompiled executables are provided for various operating systems. R has a command line interface. Multiple third-party graphical user interfaces are also available, such as RStudio, an integrated development environment, and Jupyter, a notebook interface.
