I just want to briefly describe how to install R for a Windows machine. So the first thing you need to do is launch your web browser. So I'll do that here. I'm using Chrome but it really doesn't matter. And you need to go to the Comprehensive R Archive Network, or CRAN, so let's type that in here. And you'll see that at the top there's three options. There's Linux, a Mac and Windows. So you can go to the Windows version here. And you want to click on the base link here. So you can just click on this link and the download will start. And so depending on how fast your Internet connection is, this might take a few minutes. Okay, so the download's finished. I'm going to click on this. And so, you can choose your language here. There are a number of choices in terms of the translations that you can choose from. So I'm going to choose English because that's my language. And then you can just click through the installer. It'll kind of walk you through the various steps, and so we'll do that right now just to see what the options are. If you click on Next, you have to agree to the license, which is the GNU General Public License. So feel free to read it and then click on Next. Then usually the default installation directory is fine, so I'm going to go through this. The default user installation is fine. There are other kind of installation setups that you can choose from. If you know you have a 32-bit machine, it may be an older macihne, you could click on that. By default it will install both versions, so you don't have to really worry about that. So, just click through Next on this one. And you can choose to take all the defaults or you can try to customize your start-up. I'm going to customize the start-up just so you can see what the options are here. So, this option here asks you whether you want an MDI or SDI interface, so what that means basically is do you want R to kind of run in one big window. You know, with kind of different sub-windows inside of a big window. Or do you want it to run kind of like separate windows? I prefer to use the STI mode, so the console will be in one window and the kind of graphics window will be a separate window. I just kind of, I feel I like that a little bit better, it's easier to work with. So I'm going to click on the SDI option. And then you can choose how you want to look at your help files. The HTML help is a little bit nicer, it's prettier to read, and the plain text help is, well, it's just plain text. So maybe I'll just click on plain text just to be different. And then you can choose whether you want Standard or Internet2 Internet access. This, generally speaking, you should not mess with, so you just click on Next. You can create a shortcut in the start menu, so that's usually a good idea. And you can usually choose the defaults here, in terms of creating a desktop icon. Unless your desktop is very cluttered and you want to avoid that. So these defaults are fine, so I'll click on Next. And then it will start installing the files on your computer. So now it's done. And we can just click on Finish here. And you've now installed R on your computer. And I see I've got a desktop icon here. So I'll just double-click on that. And there we are, we're running R.
