Background

What is it?

Rcgi is a web interface to the R statistics language. It can either present an "input box" which allows the user to enter most commands (or a program similar to an Rweb-module can pass it commands), or it can be called directly from a web page by mixing user input boxes and code embedded in the page.

This embedded code idea as an innovation of this software over its peers. It allows web authors with a knowledge of R to write simple examples for the students without needing to know a CGI scripting language.

Motivation

Rcgi was written as a lighter alternative to Rweb with more "reasonable" dependencies. We didn't just use Rweb as we couldn't get the source code at the time, we don't have R and latex2html installed on the same machine, latex2html can be a pain to install (we use tth) and the JavaScript et al causes our campus browsers problems.

Licence

This software is released into the public domain with the proviso that any derivatives have source code placed in the public domain also. Violating this condition makes the software revert to the property of the School of Mathematics, University of East Anglia.

I trust you to credit the original authors.
