R shiny / rCharts / nvd3 : override fixed width and height?

Question

I've come to the realisation that all my attempts to set the width and height for my nvd3 chart (including adding my own css) are being sabotaged by some inline css:

<style>
.rChart {width: 800px; height: 400px}
</style>

What to do? I don't know where this is coming from or how to stop it from being output. Also, I can't think of any reasons why anybody would have set a fixed dimension for a plot in the first place...

UPDATE : I did not know there was a renderChart2() per comment below. I tried it as follows:

  output$testChart <- renderChart2({

    n1 <- nPlot(xxx~yyy, data = xyz, type = 'discreteBarChart')
    n1$xAxis(axisLabel = "Heading")
    #bug with nv.d3.js - without width, the ylabel is off the chart area and invisible?
    n1$yAxis(axisLabel = "label", width = 40)
    n1$set(title = "Title")
    n1$chart(width=1600, height=800, tooltipContent = "#! function(key, x, y, e){ 
  return 'x: ' + e.point.x+ '<br/>  y: ' + y 
} !#")
    n1$addParams(dom = 'testChart') #need this line, else it doesn't get rendered in dom!
    return(n1)

  })

And I got this in the html output (checked with firebug):

<div class="shiny-html-output rChart Nvd3 shiny-bound-output" id="testChart"><style>.rChart {width: 800px; height: 400px} </style>

<div class="rChart nvd3" id="testChart"></div>
<script type="text/javascript">
 $(document).ready(function(){
      drawtestChart()
    });
    function drawtestChart(){  
      var opts = {
 "dom": "testChart",
"width":    800,
"height":    400,
...(etc)...

Try changing:

n1$chart(width=1600, height=800, tooltipContent = "#! function(key, x, y, e)

to:

n1$set(width=1600, height=800, tooltipContent = "#! function(key, x, y, e)
