r - tagAssert 创建一个 Shiny 的仪表板时出错

我正在制作一个 Shiny 的仪表板,但出现此错误:

Error in tagAssert(body, type = "div", class = "content-wrapper") : 
Expected tag to be of type div

我不知道这意味着什么。谷歌搜索给我什么。我有我的dashboardHeader、dashboardSidebar、dashboardBody。这是完整的代码,因为我不知道错误在哪里。 Shiny 应用程序正常工作,只是将其放在仪表板中而已。
library(shinydashboard)

shinyApp(ui = dashboardPage(
#Header
dashboardHeader(title = "Basic dashboard"),

#Sidebar
dashboardSidebar(
selectInput("dataset",
"Pick a Project",

最佳答案

  • 您的 sidebarMenu()在外面 dashboardSidebar()
  • 你写了 plotoutput()而不是 plotOutput

  • 您的代码(已更新):
    library(shinydashboard)
    library(shiny)

    shinyApp(ui = dashboardPage(
    #Header
    dashboardHeader(title = "Basic dashboard"),

    #Sidebar
    dashboardSidebar(
    selectInput("dataset",
    "Pick a Project",
    choices = c("ALTTobacco - 5/10/17 through 6/11/17",
    "BehavioralFactors - 2/13/17 through 3/15/17",
    "CobbParks - 4/11/16 through 5/5/16",
    "CobbSeniors - 3/16/17 through 5/4/17",
