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.

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
