Why not use Sys.info() or R.version to find that? > stefano > p.s. if one day R will run on the iPhone, you have to change the > question below into "Do you see an apple logo somewhere on your > device?") And in any case other OSes run on Apple hardware: I believe several R developers use a MacBook to run Windows or Linux. Beyond that, R could be running remotely, not on the computer to which the keyboard is attached. Then there is virtualization which allows one OS to run under another. So I don't if the question was really - is R running on Mac hardware - is R running under MacOS X GUI - is R running under Darwin ... which all seem reasonable questions, but different ones. (MacOS X vs Darwin is similar to Solaris vs SunOS: the first of the pair includes a user interface and not just an OS.) > > On 20/set/07, at 00:37, Hin-Tak Leung wrote: > >> On linux boxes, >> version$os and R.version$os >> is 'linux-gnu'.
