2.It’s open source.

3.You can run it on any machine, including Windows, Mac, Linux – even your iPad*

4.Stay on the cutting edge: new packages added constantly.

Proble

m: R is too complicated. I

want a graphical interface like SPSS or SAS.”

R has a Graphical User Interface: R Commander (RCmdr)

Looks similar to SPSS to me!

Go to http://www.r-project.org/ and follow the

instructions…

First time opening R, your window will look like this:

Installing R

Then, just go to: Packages -> Install

Package(s)

Installing R Commander

Choose a mirror (I don’t think it matters, but I always choose USA – TX)

Installing R Commander

Choose RCmdr, and click “OK”

-----meanwhile, note all of the free

packages you can download later….

Installing R Commander

Go to “Packages” again, but this time, choose “Load Package”, and Choose “RCmdr”

Using R Commander

Import is under Data -> Import Data

You can upload plain text, dat, and even EXCEL files.

Now, play with the commands… they’re not identical to SPSS/SAS, but similar.

Next, import your data
