ui = bootstrapPage(
  selectInput('def_fill', 'Select Color', c('blue', 'green')),
  datamapsOutput('mymap', 800, 400)
)

server = function(input, output, session){
  output$mymap <- renderDatamaps(
    datamaps(
      fills = list(defaultFill = input$def_fill)
    )
  )
}

runApp(list(ui = ui, server = server), launch.browser = rstudio::viewer)

Map with External Data

)

server = function(input, output, session){
  output$mymap <- renderDatamaps(
    datamaps(
      scope = 'pcs', 
      geographyConfig = list(
        dataUrl = htmlwidgets:::attachment('data/pcs.json')
      ),
