R + d3.js Parallel Coordinates of partykit ver 2 with interactive querying

This example builds on the first example by adding the ability to explore the partykit / rpart splits by clicking on the node information. When clicked, the parallel coordinates will be brushed corresponding to the query from the clicked node.

Introduction

This d3.js parallel coordinates plot is another experiment in how we might use interactive plots in Javascript to represent a partykit / rpart object from R. The example builds on this d3.js collapsible tree plot. Eventually, it would be nice to combine the tree and parallel coordinates into a layout with synced interactivity.

### Almost No [`rCharts`](http://rcharts.io) Also, this is fairly different from most of my interactive plots from R in that it almost completely avoids [`rCharts`](http://rcharts.io) (almost because I did use its `publish` to make this gist). I chose to exclude `rCharts` for two reasons:

1. demo how we can use htmltools to build html/js in R
2. help users understand some of the things rCharts does for us, such as dependency management, rendering, sharing, multi-format publishing, etc.

### Reproduce I would love for others to reproduce, fork, and improve this.

### Thanks

It is impossible to make this list complete, but I would like to thank

• Mike Bostock for d3js
• Kai Chang for d3.js parallel coordinates
• RStudio for RStudio and htmltools
• Kun Ren for the mind-blowing rlist and pipeR
