Setting up R & R Studio
R is a widely-used, open source statistical analysis platform. RStudio is an integrated development environment for R – that means it makes using R easier!
You should install both software packages – R and RStudio! Don’t just install R or your life will be difficult!
We’ll be using this software to do some analytics! You can get a full copy of the software – PC or Mac – for free!
First download and install R:
- If you have Windows
- Download the installer file for R (this is a direct link to the install file).
- Make sure you keep track of where you save the installer.
- Double-click on the installer file and follow the instructions (just accept the default settings).
- If you have a Mac
- Download “R-3.2.1-snowleopard.pkg” if you have Mac OS X 10.6 or “R-3.2.4.pkg” if you have Mac OS X 10.9 or higher.
- Make sure you keep track of where you save the installer.
- Do whatever it is you “Mac people” do to install software! (I don’t have a Mac!)
Now download and install RStudio:
- Download the appropriate installer: Windows or Mac.
- Make sure you keep track of where you save the installer.
- Install the software! Just accept the default settings.
After both are installed, you’re always going to run RStudio, which will use R behind the scenes to give you a pleasing analytics experience!
