在R Studio服务器1.0.153上运行简单的R Shiny应用程序时出错

Question

I am using R studio server 1.0.153 on citrix virtual machine. I just wrote a simple R shiny program and saved the file as app.R.

## app.R ##
library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(),
dashboardSidebar(),
dashboardBody()
)
server <- function(input, output) { }
shinyApp(ui, server)

When clicked on run app, I get the following error snapshot. Please help me to run the app.

Answer 1

Try this:

library(shiny)
library(shinydashboard)
ui <- dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody()
)

ui <- dashboardPage(header,sidebar,body, skin="blue")
server <- function(input, output) { }


app <- shinyApp(ui,server)
runApp(app,host="0.0.0.0",port=5050)
