Plotly Update
When plot.ly first hit the scene, I was like, woah, this is awesome, knitr support and everything!
I recently asked them about building better dashboards, and they sent me this info — apparently there is some support for integrating plot.ly graphs into shiny apps, if you’re already comfortable building shiny apps.
I’m hoping they start building in functionality that will make it even easier to integrate custom sliders and drop-downs for messing with graphs on the fly. For now, though, it’s still a really nice way to make your R output more interactive.
