[Rd] Question about Rweb

[Ted Byers]

Hi Simon,

Any chance of getting step by instructions on setting it up to work with a
web server like Apache's httpd server (I have Apache's web server running,
actually a couple instances on different ports, and I do all my CGI
programming using Perl)?

I am not so much looking to provide a web interface for working with R, but
rather want to write CGI programs that use R for specific analyses and
graphics.  I was considering writing my R scripts as usual (using the
capabilities of QRMlib and RQuantLib, in particular), and have them invoked
by a cgi script written in perl.  But your description suggests it can be
made faster.  Each package I looked at for doing this was interesting, but I
always got stuck at the point of figuring out how to get Apache's httpd
server to run my R scripts.  Your description suggests that a request
requiring R can be just passed onto Rserve, but how does one set that up;
i.e. to pass the request arguments through to the R script, and to tell
Rserve which R script to use?

Any insights on setting this up would be appreciated.

On http://rforge.net/FastRWeb/files/, I read that FastRWeb is to be
installed using "install.packages('FastRWeb',,'http://www.rforge.net/')",
but that gives me the following message:

> install.packages('FastRWeb',,'http://www.rforge.net/')
Installing package(s) into 'C:\Users\Ted\Documents/R/win-library/2.12'
(as 'lib' is unspecified)
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package 'FastRWeb' is not available

This was on:

R version 2.12.0 (2010-10-15)
Copyright (C) 2010 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: x86_64-pc-mingw32/x64 (64-bit)

Thanks

Ted
