Shinydashboard +有向图+ valueBox

Question

在shinydashboard中，有一些图形和valueBox之间的不兼容吗？为什么不设计ValueBox呢？有人能帮我吗？

## app.R ##
library(shiny)
library(shinydashboard)
library(dygraphs)


ui <- dashboardPage(
  dashboardHeader(title = "Monitoramento Banco de Dados"),         
  dashboardSidebar(
    sliderInput("DateInput", "Periodo", -30, 0, c(-15, 0), pre = "D.")
  ),
  dashboardBody(
            fluidRow(     
                valueBoxOutput("box_Locks"),
                valueBoxOutput("box_PLE"),
                valueBoxOutput("box_CPU")
              ),
            fluidRow(
                 dygraphOutput("plot1")
            )
       )
)

server <- function(input, output) {

 output$box_Locks <- renderValueBox({
    valueBox("7", "Locks", icon = icon("area-chart"), color = "yellow")
  })

  output$box_PLE <- renderValueBox({
    valueBox("1500", "PLE", icon = icon("area-chart"), color = "green")
  })

  output$box_CPU <- renderValueBox({
    valueBox(paste0(20, "%"), "CPU", icon = icon("area-chart"), color = "red")
  })

  output$plot1 <- renderDygraph({
    lungDeaths <- cbind(ldeaths, mdeaths, fdeaths)
    dyRangeSelector(dygraph(lungDeaths, main = "Deaths from Lung Disease (UK)"), dateWindow = c("1974-01-01", "1980-01-01"))
  }) 




}

shinyApp(ui, server)

版本：

> R.version.string
[1] "R version 3.3.1 (2016-06-21)"
> packageVersion("shiny")
[1] ‘0.13.2’
> packageVersion("shinydashboard")
[1] ‘0.5.1’
> packageVersion("dygraphs")
[1] ‘1.1.1.0’

这是结果，我不知道为什么不显示值框：
