Nowadays, R language is a widely used tool in the field of statistics. It is a free, free and open source software belonging to the GNU system. It is an excellent tool for statistical computing and statistical drawing. RStudio is an integrated development environment for R, and it is easier and more convenient to use it to learn and practice R programming.

After opening RStudio, the window shown above appears with three separate panels. The largest panel is the console window, which is where you run your R code and view the output. That is, the console window you see when running native R. Other panels are exclusive to RStudio. Hidden in these panels include a text editor, a drawing interface, a code debugging window, a file management window, and more.
Note: Some people may ask, do I still need to download R with RStudio?
Even with RStudio, you still need to have R installed on your computer in advance. RStudio is just a tool to assist you in editing with R, it does not come with an R program.
