Why are there so many versions of R?

There are many versions of R because it is a powerful programming language that can be used for a variety of purposes. Some reasons why there are so many versions of R include the following:

-R is open source, which means that it is free to use and distribute. This allows for people to create their own versions of the software if they want to use specific features or modifications not included in the original version.

-R has been developed over time by different groups of people, which has resulted in different features and modifications being added to the software. This makes it possible to find a version of R that suits your needs specifically.

-R is also available as an online platform, which means that you can access and use it from anywhere with internet access. This makes it easier for people who work on projects outside of traditional office hours or who need to work on multiple projects at once.
