Take a look at Rweb from Jeff Banfield (http://www.math.montana.edu/Rweb/)
or Rcgi which is a CGI WWW interface to R by Mark J Ray. This information
is also mention in the FAQ.

<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

I just try the following on Linux (Mandrake7.1) and it works:
file (tryplot.R:
jpeg("tryplot.jpg")
plot(rnorm(100))
dev.off()
>From the shell prompt:
R --no-save < tryplot.R > tryplot.Rout
This generated the JPEG file, and dump the R session text to tryplot.Rout.
If I understand correctly, jpeg() will *not* work with R BATCH, since it
depends on x11(), and x11() isn't available when run under batch mode.

I run scripts in R like this: R --vanilla < script.R This is on Linux/Unix. Don't know about DOS/Windows. But I learned about it from looking at the R man page: man R. There is also a BATCH mode. I haven't tried that.

There are a number of ways of using R non-interactively. The simplest method is just to put your R commands in a file, say 'myscript.R' and do (Under Unix/Linux:) R --no-save < myscript.R > myscript.out (Under MS-Windows) Rterm < myscript.R > myscript.out This will run R, feeding it the commands in 'myscript.R' and send the output to 'myscript.out'. Note that if you want graphics saved to a file that you should explicitly open (and then close!) the desired device. -Greg > -----Original Message----- > From: Chris Milkosky [mailto:c.milkosky at xpedite.com] > Sent: Friday, October 05, 2001 9:24 AM > To: r-mailing-list > Subject: [R] non-interactive R usage... > > > <Newbie alert> Hello all! </Newbie alert> =) > > Hi all, > > First of all, I'm new to R and I'm REALLY REALLY impressed > by it.

This also allows you to set up environment variables appropriately in a Unix cron job. Here's my template. I'm not sure about graphics, though. ###### Begin Code: ###### #!/usr/local/bin/perl -s (($arg1, $arg2) = @ARGV) || die "Must supply 2 arguments"; $f += 0; # -f flag, force numeric $ENV{"R_LIBS"} = "$ENV{SetThisAppropriately}/Rlib"; $| = 1; # Don't buffer Perl output $script = "/tmp/rwrap$$.R"; $outfile = "/tmp/rwrap$$.out"; open(SCRIPT, ">$script"); print SCRIPT <<EOF; arg1 <- "$arg1" arg2 <- "$arg2" fflag <- $f EOF print SCRIPT <<'EOF'; Z<-require(misc, q=T) # Quietly! # YOUR CODE HERE q() EOF close(SCRIPT); system("R --vanilla --slave < $script > $outfile"); $? && die "Aborted in R with errcode $?"; # Check for successful R completion unlink $script; # The script remains for debugging if failure ####### End Code ####### -- David Brahm (brahm at alum.mit.edu) -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
