Ramnath, I'm running into some trouble moving a couple of shiny apps with rCharts on to glimmer. As a test case, I just copied this server/ui code and its in a "dummy" application folder (identical code as this): http://glimmer.rstudio.com/vivekpatil/dummy/
Can you please see if you are able to run it? Thanks.

Its funny but it works from a different computer... in both instances, chrome browser. The other apps are fine too. Thanks. No issue here.

I don't understand where you get the data? How can I use my own data (eg,csv or excel file)?
May you help me? I'm new in this area. Regards

I'm having trouble implementing a slightly different example where the nplot is a scatterplot that switches between two variables. The plot doesn't appear even if I remove the switch by replacing datasetInput() with Murder in server.R.

Any ideas on how I can make this work?

server.R

require(rCharts)

shinyServer(function(input, output) {   
  datasetInput <- reactive({
    switch(input$crime,
           "assault" = Assault,
           "murder"  = Murder)
  })
  output$arrestPlot <- renderChart({
    w2 <- nPlot(datasetInput() ~ UrbanPop, 
                data = USArrests, 
                type = 'scatterChart') 
    w2$chart(tooltipContent =   "#! function(key, x, y, e){ 
             return e.point.row.names
  } !#")
    w2$set(title = "Water Footprint vs. Protein: California")
    w2$xAxis(axisLabel = 'Protein (%)')
    w2$yAxis(axisLabel = "Water Footprint: California (L/100g)" )
    w2$chart(showControls = F)  ## turn off magnify.
    return(w2)
})
}

ui.R

require(rCharts)

shinyUI(pageWithSidebar(
  headerPanel("rCharts: Interactive Charts from R | NVD3"),

  sidebarPanel(
    selectInput(inputId = "crime",
                label = "Crime:",
                choices = c("assault","murder"),
                selected = "assault")
  ),
  mainPanel(
    showOutput("arrestPlot", "nvd3")
  )
))
