Mac OS X jpg

Hi,
	I am using R 1.9.0 (2004-04-12) for Mac OS X.	I am having trouble 
printing to a jpg file. This only happens when I use R in batch (with 
the BATCH option) mode. If I launch the R GUI or the command line 
version and run the script from either, I have no problems. Only when 
running in BATCH mode I get a file with the same name as my script 
where I find the following message at the end:
When I run the same script with the only difference that it prints to 
a postscript file instead, all works fine.

	Any  suggestions as to what could the problem be?

	thank you in advance,

I think the message is very clear.  Try ?BATCH

     Using 'R CMD BATCH' sets the GUI to '"none"', so none of 'x11',
     'jpeg' and 'png' are available.

and ?jpeg

     R can be compiled without support for either or both of these
     devices: this will be reported if you attempt to use them on a
     system where they are not supported.  They will not be available
     if R has been started with '--gui=none' (and will give a different
     error message), and they may not be usable unless the X11 display
     is available to the owner of the R process.

The bitmap() device will work under R CMD BATCH.

Failure to consult the documentation, I believe.
