In this video, I'm going to to briefly show how you can install R on the Mac.

It's a very simple process.

You just have to, it only takes a few steps.

So the first thing you need to do is open your

web browser, and go to cran, says the comprehensive R archive network.

So you can just type in cran here, [SOUND]

and you'll see that, [COUGH] there are a number of options for you to

download here for different platforms, and so

we're going to download the Mac platform here.

So we go to download R for the Mac.

And you see that the latest version here, is version 3.0.3.

You want to download this package file here, so just click on

this, and you'll see that the download meter will start going.

And it might take a few minutes depending on the speed of your internet connection.

So just be patient.

Okay, so its finished downloading.

[BLANK_AUDIO]

So I'm just going to open up here, the

package and you can see it'll start the installer.

Uh,and it'll guide you through all the steps you need to install R 3.0.3.

So, I'll click continue here, and this is

just the description of what's going to get installed.

Click continue.

The software license agreement is the

[UNKNOWN] new general public license version 2.

So you should agree to the license, after having read it of course.

And then, you can just click install here, and

you might have to type in your administrator password.

So, just go ahead and do that.

[SOUND] And it'll start installing the files on your computer.

[BLANK_AUDIO]

[SOUND].

Now that's finished, I can hit close, and then it'll be in my Applications folder.

So I can just go to my Applications folder,

which is right here, and there alphab, alphabetic order.

So, I'll just scroll down to R, and there it is.

[BLANK_AUDIO]

And there you have it.

You have an R, installed R on your computer,

and now, you can go ahead, you can just

use it directly, or if you want to you

can install, an interface like R studio, if you like.
