Switch from rjson to RJSONIO about rcharts

seems to work well; thanks

I am going to think this over before switching. The main advantage of this approach is that you can write the JS functions with new lines and the payload does not get screwed up. This would then allow us to pass arbitrary JS objects from R, not just functions.

As I struggle with date handling in the various libraries, I am thinking this functionality might be necessary. I'll start a new issue to discuss the handling of dates in x.

Yes. There should be a way to do this within R rather than relying on d3 to do the formatting. I think you are the best person to be able to resolve this, as you probably work with lots of time series. Let me know if you want to test out some ideas/thoughts.

Thanks again for doing this.

I need to add a few tests to make sure that this feature works as I make more changes to rCharts. I am thinking a more organized test suite would do a lot of good, automating things. I wonder how tests work when it involves visually inspecting a page opened by the browser.

Done.
