Is it possible to run R in Processing through rJava/JRI? If I deployed a Processing app on the web, would the client need R on their system?

I'm looking to create an interactive information dashboard that I can deploy on the web. It seems that Processing is probably my best bet for the interactive/web part of things. Unfortunately, it doesn't look like there are many math/stats functions built-in. And there aren't any libraries for plotting data either. 

I've been using R and gpplot2 for a few months and am thrilled (amazed) at how easily it manipulates and plots data. 

So I'm wondering now if can get the best of both worlds and run R through a Processing applet.

From the [JRI](http://rosuda.org/JRI/) website:

>

>  Basically it loads R dynamic library
>  into Java and provides a Java API to R

>  run R code inside JRI that calls back

>  rJava to provide a full Java GUI for

Thanks for the advice :)
