[R] how to make R plot under Linux

[Don MacQueen]

The classic test for a properly set up X11 is to issue the command
    xclock
at the prompt (on the linux box). (this assumes the linux box has 
xclock installed, but that is highly likely)

If it works, the X11 forwarding is set up. If not, then, evidently 
not, but in the latter case at least you say it isn't R.
