[R] postscript error

[R.E. Darnell]

I have generated a graph on the X11 device, but when I

> dev.copy(postscript)
postscript 
         3 
> dev.off()
X11 
  2 
>

the Rplots.ps file is generated but contains a prologue only.

Can anyone suggest what I am doing wrong? Just to anticipate the
upgrade reply ...

and I have attached the postscript file at the end. (It is small)

Thank you
