The message "unable to open connection to X11 display ''"
means
your own machine cannot open a xterm from the machine running R.
You have to have an X server running on your own machine, and
allow X display from the machine running R.
Hope this helps.

Subject: [Rd] X11 Problems
Hi all,
I'm having trouble getting x11 to work with R. (This is on Debian testing.)
I
installed r-base and r-base-dev, and then r-cran-cairodevice. I also tried
installing the Cairo package within R, which appears to work fine.
This what I'm seeing:
> capabilities()
jpeg png tiff tcltk X11 aqua http/ftp sockets
TRUE TRUE TRUE TRUE FALSE FALSE TRUE TRUE
libxml fifo cledit iconv NLS profmem cairo
TRUE TRUE TRUE TRUE TRUE TRUE TRUE
> x11()
Error in X11(d$display, d$width, d$height, d$pointsize, d$gamma, d$colortype, :
unable to start device X11cairo
In addition: Warning message:
In x11() : unable to open connection to X11 display ''
Any help would be appreciated!
Thanks,
Kay
