Rather than starting straight from from scratch right now, you can follow along and work with a pre-existing set of files which should hopefully look familiar - the solutions from the basics of R exercises from this course. It is possible to totally re-organise the layout of these panes if you want - but for now I will assume you are happy with these default layouts. This is another way to access the same help menus we mentioned in module 1 which can appear by typing ?functionname into the console. You can also see a point-and-click access to the help menus. The Packages tab shows a list of the currently installed packages, and allows you to install new packages or update existing packages. If you create plots then these will appear in the Plots tab although interactive plots or other interactive output will appear in the Viewer tab and if you create any powerpoint style presentations these will appear in the Presentation tab. Bottom right - this is also a multi-purpose pane where by default it links to the file manager so you can open and view files within R.You can also see a history of your recently submitted commands, a list of open connections to external data sources, and some built in tutorials that could help you on specific topics. This is where all of your stored objects will be listed. Top right - by default this shows the "environment" pane.Effectively this is exactly the same thing - and now everything else covered from this point on will be specific to only RStudio. You will notice this part looks extremely similar to what you saw when you opened up "R" the standalone software application earlier. Left hand side: This is the console window, by default this is where you can type in commands, run code and where output would be displayed.Here you will see three main "panes" initially, assuming this is the first time you have opened R. Looking into the methodology, and given the skew in that sample towards software developers rather than researchers, I would actually suspect that to be an underestimate!įirst let's open up RStudio. In a 2022 survey 78% of R users indicated they use RStudio as the way in which they interacted with R ( ). RStudio was not the first of these, but over time it has developed to become by far the dominant tool used by those working with R (the language) on a regular basis. The general user un-friendliness is what led to the development of IDEs (Interactive Development Environment) for R, to help make working with R easier. So I could try and see if 2+2 still equals 4:Īnd I can see that R is at least functioning correctly as a calculator. You can see a console window in which you can run write and run commands. Opening R you see a very old fashioned, and quite intimidating interface! There are very few features within the R GUI to help you get started, or to optimise your workflow at all. If you search in your program files you should find it: Very occasionally when you look up resources online you will see people using R without using RStudio. Usually when we talk about R we mean the language itself - but when you downloaded and installed this you may have seen that R is a standalone program in itself that you could use. If you are having any issues with the downloading and installation process please make sure that you have administrator rights on the computer you are working on.īefore getting into RStudio - it is worth taking a quick step back to understand what exactly "R" itself is. You should not need to change any of the default settings as you work through the installation process. Once you have completed the installation of R you can download RStudio, the link below should provide the recommended link to download based on your operating system. The first thing to install is the most recent version of R for your operating system: Download R for Windows R and RStudio are both updated on a very regular basis, and some of the features we may highlight in this course may not be available if you are using an older version. Both R and RStudio are open source software tools, so these can be downloaded from the internet for free, forever.Įven if you have prior installations of R or RStudio on your computer - please ensure you download and install the most recent versions of both programs.
