[R] Problems for runing R in BATCH to generate PNG/JPEG files

[Prof Brian Ripley]

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.
