I would like to get output of below into a html string.

library(rCharts)

p2$xAxis(axisLabel = 'Weight')
p2$chart(size = '#! function(d){return d.gear} !#')
html <- p2$print()

How to get the complete html file which gets launched into a string.

Answer 1

You can capture the html as a string using the render method

html <- p2$render()
