Highchart not rendering in shiny using 'Highcharter' package

Question

I'm having problems getting highcharter to work with my shiny app. What's really weird is that some of the highcharts work and some don't. It's probably some dumb mistake I'm not catching. Anyways, here's some code:

library(shiny)
library(highcharter)
library(ggplot2)

ui <- fluidPage(
  column(width = 12,  
               highchartOutput("hc_more.FA",height="500px")
  )
)
server = function(input, output) {

  output$hc_more.FA <- renderHighchart({
      hchart(diamonds$carat)

  })

}

shinyApp(ui = ui, server = server)

Here's what my app looks like?

Here's my session info:

Any ideas whats going on?

Answer 1

The reason is that you cannot have a dot in the chart name. Remove the dot and it works.
