R help - Jun 2003 - Problems for runing R in BATCH to generate PNG/JPEG files

Hello all:

After I compile the R-1.7 with the follows in
Linux7.3:

configure --with-x --with-jpeglib --with-libpng
--x-includes=/usr/X11R6/include
--x-libraries=/usr/X11R6/lib
and make and make install. The R is able to generate
PNG/JPEG files from the command line. However, when I
put the same commands in a batch file and run:

R --gui BATCH R.Batch.file 

It gave me a error in the R.Batch.file.Rout:

Error in png("myplot.png") : R_X11 module cannot be
loaded
In addition: Warning message: 
X11 module is not available under this GUI 
Execution halted

Would you please guide me through to fix the problem?
Your help is greatly appreciated.

Charlie

1) Read ?BATCH, carefully.  
Note that R --gui BATCH isn't valid syntax.

2) Read ?png, carefully.

3) So you need to not use BATCH *and* provide an X server: I use Xvfb
on Linux (but on Solaris the console is available to batch processes).

That's not a Linux version number!  RedHat 7.3, perhaps?

The help pages *are* very helpful once you read them.
