Fun with V8 console

console.R

# Execute this script line by line in your favorite IDE
# It does not work via source()
library(V8)
data(diamonds, package="ggplot2")

# Create session
ct <- new_context()
ct$source("http://cdnjs.cloudflare.com/ajax/libs/crossfilter/1.3.11/crossfilter.min.js")
ct$assign("diamonds", diamonds)

# Enter the JavaScript console
ct$console()

//now we are in javasript :)
var cf = crossfilter(diamonds)
var price = cf.dimension(function(x){return x.price})
var depth = cf.dimension(function(x){return x.depth})
price.filter([2000, 3000])
JSON.stringify(depth.top(10))
