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
