[Rd] Sweave/ESS-like tools for HTML

My university provides me with a powerful course management system for the courses that I teach. Among other things I can create a wiki for the course, which is very convenient for cross-linking different bits of the course.

Naturally I use R extensively in my teaching and I want to incorporate R code, output and graphics in such a wiki. If I were producing LaTeX sources instead of HTML sources I create .Rnw files for Sweave and I would edit them using ESS in emacs.

What options do I have for producing HTML with embedded R content and what is a good, preferably emacs-based, way of editing the source code?

One basic problem is trying to present mathematical expressions in HTML (see http://www.cs.tut.fi/~jkorpela/math/) but, aside from that, there are questions of presenting input R expressions and the corresponding output and of incorporating graphics files produced by R. I could try to use latex2html or texi2html but the output from latex2html at least would be quite inconvenient to use because it generates so many linked files. Once they are uploaded it would be horrible trying to get all the links straightened out.

In a sense there are already tools for this type of output from .Rd files. Would it be best to use those tools or to use texinfo tools or ...?
