Hi! Is there any way to test if R is running on a Mac? I usually use value of .Platform$OS.type for windows or unix, but Mac falls in the latter group. Thanks, Gregor
I had the same problem. The following line using either 'apple' or
'darwin' does the job for me (tested on many different Macs):
length(grep("apple", tolower(Sys.getenv("R_PLATFORM")))) !=
0

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 r-devel-request at r-project.org wrote:> Send R-devel mailing list submissions to > r-devel at r-project.org > Message: 1 > Date: Wed, 19 Sep 2007 15:41:22 +0200 > From: Gorjanc Gregor <Gregor.Gorjanc at bfro.uni-lj.si> > Subject: [Rd] How to test if R is running on a Mac > To: "r-devel at r-project.org" <r-devel at r-project.org> > Message-ID: > <F189E18BBAA8B6479F618B9044CF4E9C0188517825 at owa.bfro.uni-lj.si> > Content-Type: text/plain; charset="us-ascii" > > Hi! > > Is there any way to test if R is running on a Mac?
