This is a huge stretch, but will there be any support for noweb?

Whenever I use LaTeX, it's usually for math/physics/stat homework where either computation or graphs are involved. It would be lovely if I could somehow inject (for example)

    <<echo=FALSE,fig=TRUE>>=
    x <- -5:5
    y <- (x - 2)^2 - 5

    plot(x, y)
    @

into the page and have a graph show up.
