What is R and why do you need it?
R is a free software environment for statistical computing and graphics
R is an open source project that was started in 1995 by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand. It is based on the S language, which was developed by John Chambers at Bell Labs in the 1970s. R provides a flexible and powerful platform for data manipulation, calculation, and graphical display. It can run on various operating systems, such as Windows, Linux, and MacOS.
R can help you perform data analysis, visualization, and modeling
R has many features that make it suitable for data science, such as:
It supports multiple data types, such as vectors, matrices, lists, data frames, and factors.
It has built-in functions for common statistical tests, such as t-tests, ANOVA, regression, and correlation.
It has a rich set of packages for specialized tasks, such as machine learning, natural language processing, spatial analysis, and bioinformatics.
It has a comprehensive system for creating high-quality graphics, such as histograms, scatter plots, box plots, and maps.
It has an interactive console that allows you to enter commands and see the results immediately.
It has a scripting language that allows you to write your own functions and programs.
R has a large community of users and developers who contribute packages and support
R is not only a software but also a culture. It has a vibrant community of people who use it for various purposes and share their knowledge and experience. Some of the ways that the community contributes to R are:
They maintain the Comprehensive R Archive Network (CRAN), which is a repository of over 18,000 packages that extend the functionality of R.

Install UCRT if you have an older system
If you have a Windows system that is older than Windows 10, you might need to install the Universal C Runtime (UCRT) before installing R 12. This is a component that provides support for some C functions and libraries that are used by R. You can check if you need to install UCRT by running the following command in a command prompt:
where ucrtbase.dll
If you see a path to the ucrtbase.dll file, then you don't need to install UCRT. If you don't see anything, then you need to install UCRT from . Choose the appropriate update for your system and follow the instructions.

For example, the checksum of R-4.3.1-win.exe should be 7f9c0b8f0e9c7e8c2d9c8f2d0f9b0d7e.
