What is Rstudio? RStudio is an integrated development environment where we get to write, execute or code. We also get some user friendly integrated tools. There are two formats of the RStudio software one being the desktop version, and the other being the RStudio server, which is accessible via a web browser. If I take us to the URL https://www.rstudio.com/products/rstudio/ we see this list available. I will then click on the RStudio desktop because that's the one we're gonna be looking at today. Here we have an overview of what's potentially available inside the RStudio desktop. For now I'd like to make note that this is the free version. I'll click on download RSudio desktop this will take me to a new URL, which gives me the choice between choosing an open source license or a commercial license. 

For today I'm choosing to download the free version. At this URL we're now told there are two things you need to do. Firstly, you need to make sure you have installed the R programming language independent of the RStudio desktop package. and thereafter step two, you need to download the RStudio desktop, which automatically at the top of the page will give you a box to click on based on your operating system. In my instance, I'm using Windows so I will click on download RStudio for Windows. 

After I've done that, after I've downloaded the exe file and run the exe file I will then hopefully see an environment that looks like this. I see three panes in my RStudio environment. The console, on the top right I'll see the Environment tab. On the bottom right I'll see the Files tab. And traditionally, you see RStudio with four panes. So I can click on File, New, Rscript. And I can note now that there are two ways for me to interact with R, one, being the console in the bottom left, and two, being the script window in the top left
