Dear List,
I am a new Mac user and I am having problem generating png (or jpeg)
using the GUI version of R. I installed R-2.3.1.dmg (custom install with
everything selected) and X11User.pkg but I am still getting the
following X11 connection error when I try to generate a png (or a jpeg):
Error in X11(paste("png::", filename, sep = ""), width,
height,
pointsize, :
unable to start device PNG
In addition: Warning message:
unable to open connection to X11 display ''
I tried to set up the DISPLAY variable using the command:
Sys.putenv("DISPLAY"=":0")
but I am still running into the same problem.
Is there anything else I need to do or install in order to use X11? I am
using a intel Core Duo processor and OSX 10.4.7.
Thank you for your help,
Agnes

But the underlying BSD OS is basically similar to Linux. On Linux, my primary X11 DISPLAY envvar would be ":0.0", so (at a guess) I suggest you try Sys.putenv("DISPLAY"=":0.0") Hoping this helps!
