Why not use Sys.info() or R.version to find that?

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.)

Re: [Rd] How to test if R is running on a Mac
I use Sys.info()[sysname]. It returns Darwin on a Mac, Windows on MS Windows and Linux on my Linux box. Is this sufficient for your needs, I'm using R-2.6.0alpha on MS Windows and 2.5.0 on Mac and Linux at the moment. cheers, Keith Satterley Bioinformatics Division The Walter and Eliza Hall Institute of Medical Research [EMAIL PROTECTED] wrote: Send R-devel mailing list submissions to r-devel@r-project.org Message: 1 Date: Wed, 19 Sep 2007 15:41:22 +0200 From: Gorjanc Gregor [EMAIL PROTECTED] Subject: [Rd] How to test if R is running on a Mac To: r-devel@r-project.org r-devel@r-project.org Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=us-ascii Hi!

Re: [Rd] How to test if R is running on a Mac
Prof Ripley had already spoken with a better solution (Sys.info())...
The problem with system(uname) is that it depends on shell behavior
and also the availability of an external utility - 'uname' - i.e.
although it would work as intended on mac OS X, it would die on windows
due to not having 'uname' or 'uname' not working the same way... plus
the usual stdout vs console complications on windows, etc.
