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.

(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!
