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.
