Question

我在闪亮的应用程序中使用selectizeInout，我收到以下错误消息：

＆＃34;错误：无法找到功能＆＃34; selectizeInput＆＃34;＆＃34;

我在我的server.R代码中使用以下代码，但我收到上面的错误消息。

output$Choose_Molecule <- renderUI({
selectizeInput(
  'molecule', 'Select Molecule:', choices = ArgNames(),
  options = list(
    placeholder = 'Please select an option below',
    onInitialize = I('function() { this.setValue(""); }')
  )
)
})

我经历了https://github.com/rstudio/shiny/issues/412。我提供以下信息：
