如何在 ShinyDashboard 中指定 menuItem？

Question

我正在使用shinydashboard包版本 0.7.1 創建 Shiny Web 應用程序。

所以我遇到了一個問題，當我指定menuItem時沒有任何反應。

這是示例：

library(shinydashboard)
library(sqldf)
library(DBI)
library(foreign)
library(RPostgres)
library(stringr)
library(readxl)
library(ggplot2)
library(ggpubr)
library(formattable)
library(reshape2)

header <- dashboardHeader(title = "S-T")
sidebar <- dashboardSidebar(
    textInput("banc_lics", "No of license", value=1),
    dateInput("date_an", "Input date", value = "2019-02-01" ),
    sidebarMenu(
        sidebarMenu(
            menuItem("Credit Risk", tabName = "Credit Risk",  icon("abacus")),
            menuItem("Equity Risk", tabName = "Equity Risk", icon("wave-tiangle")))
        ),
    submitButton("Submit", icon("calculator"))
)

page <- dashboardBody(
    tabItems(
        tabItem(
            tabName = "Credit Risk", h1("Credit Risk"),
            fluidRow(
                box(width=12, title = "Таблица", tableOutput("data_table"))
            ),
            fluidRow(
                box(width=12, title = "График", plotOutput("data_plot"))
            ) 
        ),
        tabItem(tabName = "Equity Risk", h2("Equity Risk"))
    )
)

ui <-  dashboardPage(header, sidebar, page, skin="yellow")

server <- function(input, output) {}

shinyApp(ui = ui, server = server)

我在data_plot中沒有看到預先指定的data_table和data_plot 。

我可以處理這個問題嗎？

謝謝。

需要改變的東西很少......

1. 你有一個額外的sidebarMenu()是不必要的
2. 您需要icon("x")為icon = icon("x")

完整代碼：

library(shinydashboard)

header <- dashboardHeader(title = "S-T")
sidebar <- dashboardSidebar(
  textInput("banc_lics", "No of license", value=1),
  dateInput("date_an", "Input date", value = "2019-02-01" ),
  sidebarMenu(
        menuItem("Credit Risk", tabName = "CR",  icon = icon("abacus")),
        menuItem("Equity Risk", tabName = "ER", icon = icon("wave-tiangle"))
      ),
  submitButton("Submit", icon("calculator"))
)

body <- dashboardBody(
  tabItems(
    tabItem(tabName = "CR", 
            h1("Credit Risk"),
            fluidRow(
              box(width=12, title = "Таблица", tableOutput("data_table"))
            ),
            fluidRow(
              box(width=12, title = "График", plotOutput("data_plot"))
            )
            ),
    tabItem(tabName = "ER", 
            h2("Equity Risk")
            )
  )
)

ui <-  dashboardPage(header, sidebar, body, skin="yellow")

server <- function(input, output) {}

shinyApp(ui = ui, server = server)
