1. Installing RStudio
RStudio is an integrated development environment (IDE) that adds modern features like syntax highlighting and code refactoring to R. The strength of RStudio is that it brings all the features that you need together in one place. Before we install RStudio, we will need to install the latest version of R for our operating system as well as another program called git. Both of these software packages are integrated into RStudio, but they do not come with the RStudio IDE.
R is a statistical programming language and we need this language to use RStudio. Git is a popular version control system that will be integrated into RStudio. Version control systems like git are used to manage copies of the code you are working on. Git helps you see the differences between versions of a file so that you can get insight into why one version of your code behaves differently than another version. Git is also required to use Github, an online community where programmers share code and projects.
R is a free open source software used for statistical programming and graphics. You can get the latest version of R from CRAN, the Comprehensive R Network . This is a network of mirrored servers that have copies of R as well as R packages. R packages are extensions to the core R programming language contributed by R users in the community.
