Informal surveys that I’ve seen keep showing the number of R users increasing, while the number of SPSS and SAS users stays the same.A lot of what you learn if you really get into R is coding – and that’s something that you can use with SPSS and SAS as well. The codes themselves will change depending on your use, but the

R has a Graphical User Interface: R Commander (RCmdr) Looks similar to SPSS to me!
Installing R Go to http://www.r-project.org/ and follow the instructions…First time opening R, yourwindow will look like this:
Installing R Commander Then, just go to:Packages -> Install Package(s)
Installing R CommanderChoose 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….
Using R CommanderGo to “Packages” again, but this time, choose “Load Package”, and Choose “RCmdr”
Next, import your data Import is under Data -> Import DataYou can upload plain text, dat, and even EXCEL files.Now, play with the commands… they’re not identical to SPSS/SAS, but similar.
