Thank you all, I tried adding to the path variable ...;C:\Program Files\R\R-2.15.1\bin\x64\R.exe
I then entered r.exe --help at the Windows Command Prompt I received the same error message: "r.exe is not recognized as an internal or external command, operable program or batch file" I tried many variations or r.exe --help all with the same response. I then tried adding to the path variable: ...;C:\Program Files\R\R-2.15.1\bin\x64\Rterm.exe I receive the same error message when I enter r.exe --help and its derivatives at the Windows Command Prompt. Any other ideas?
