Mimic Highchart Polar

[ghost]

Hi,
I try to understand how programmatic approach work starting from trying to mimic polar graph for HighCharts (http://www.highcharts.com/demo/polar-spider)
I can see the huge refactoring work to gather all JS libraries into one framework and see the rPlot function.
Though, with the current state of documentation, I don't see how to start from rPlot.
So I started to investigate directly to HighChart layer and tried:

x=data.frame("S1"=c(9,8,9,1,3),"S2"=c(7,3,7,6,4))
rownames(x)=paste("factor",rownames(x))

a=rCharts:::Highcharts$new()
a$addParams(width = 550)
a$chart(type='line',polar=TRUE)
a$pane(size='80%')
a$title(text='Polarize-It',x=-80)
a$xAxis(categories=rownames(x),tickmarkPlacement='on',lineWidth=0)
a$yAxis(gridLineInterpolation='polygon',lineWidth=0,min=0)
a$data(x,pointPlacement='on')
a$printChart("testPolar")

Error in file(con, "r") : invalid 'description' argument

Can you help: what should be corrected?

Thank you,

Eric

PS: no pressure but I am really working on your sample gallery

I forgot to update Highcharts when I refactored the code base. Just pushed a fix to github and your code should work now. See here http://pagist.github.io/?5488102

Moreover rPlot is only for Polychart. A hPlot function is being worked upon, which would make things easier with Highcharts, but it would only be a wrapper around Highcharts$new(), so you will have more flexibility with the approach you are taking.

that was fast! Thanks for explanation.
I will continue investigations with this approach beginning by looking at JS solutions capabilities.
Keep up great work!
