flexdashboard是否可以将（下图）中的仪表嵌入Shiny应用程序（shinydashboard或shiny）中？
Shiny flexdashboard来自flexdashboard 网站的示例代码：
```{r}
renderGauge({
rate <- computeContactRate(input$region)
gauge(rate, min = 0, max = 100, symbol = '%', gaugeSectors(
success = c(80, 100), warning = c(40, 79), danger = c(0, 39)
))
})
```
这是我失败的尝试：
library(shiny)
library(shinydashboard)
#library(flexdashboard)
ui <-dashboardPage(
dashboardHeader(),
dashboardSidebar(),
dashboardBody(
column(6,box(flexdashboard::gaugeOutput("plt1"),width=12,title="Gauge Graph",background ="green"))))
server <- shinyServer(function(input, output, session) {
output$plt1 <- flexdashboard::renderGauge({
gauge(56, min = 0, max = 100, symbol = '%', label = paste("Test Label"),gaugeSectors(
success = c(100, 6), warning = c(5,1), danger = c(0, 1), colors = c("#CC6699")
))
})
})
shinyApp(ui = ui, server = server)
感谢您的任何提示！
