d3 and r interacting through shiny

I was amazed and delighted by the Reconstruct Gene Networks Using Shiny.  Jeff accomplished what I knew was possible but had absolutely no idea how to implement.  With the boost, I went to work combining his d3 force layout with my d3 experiments discussed in Hi R and Axys, I’m d3.js “Nice to Meet You” (On the Iphone).  Unfortunately, I could not figure out how to host the example at http://glimmer.rstudio.com See this live at http://glimmer.rstudio.com/timelyportfolio/shiny-d3-plot/, and for all the source code go to https://github.com/timelyportfolio/shiny-d3-plot.
