[R] non-interactive R usage...

[Chris Milkosky]

<Newbie alert> Hello all! </Newbie alert>   =)

Hi all,

First of all, I'm new to R and I'm REALLY REALLY impressed by it.  It's an asset to the open source community.  I can't begin to say
how glad I am to have stumbled across it in freshmeat.net...  Kudos to the developers - you've done a great job.

OK - my question may be answered by looking through documentation (I did RTFM), but I haven't noticed anything yet.  I think I must
just be missing something though.

Does R give you the capability to run a script (read as non-interactive) that would perform a statistical task, and then send output
to a file?  For example: read a set of data from a file, generate a JPEG _file_ containing a plot of the data (with some specific
stat calcs plotted of course), and then exit?

I do capacity planning and would like to be able to have JPEG plots of real time statistical data appear on web pages, so I'm
thinking that a CGI can be executed that starts R up, generates a plot, and writes it to a file.  We currently use gnuplot, but with
all of the statistical needs we have, it is turning out to be less flexible than we had hoped.

Has this been done before?  Could it be?  If so, can we pass command line parameters to our R scripts somehow?

Thanks,

Chris
