[R] Create graphs from text console

[Rainer M Krug]

Hi

I am using R 2.2.1 under Linux (SuSE 10) and would like to know if it is 
possible to create graphs, i.e.

jpeg(filename=fn)
	try( coplot( mor$I_Morisita ~ mor$Year | mor$RunStr, show.given=FALSE) )
dev.off()

from a text console?
It gives me an error message on the jpeg() command:

Error in X11(..snip..) unable to start device jpeg
In addition: warning message:
unable to open connection to X11 display.

Are there any ways to create the plot and save it into a jpeg file from 
a text console?

Thanks,

Rainer
