在 tabItem 中创建后的 .Rmd 输出在闪亮仪表板的所有 tabItems 的主体中创建第二个仪表板

.Rmd output after created in a tabItem creates a second dashboard in the body of all tabItems of the shiny dashboard

我有一个带有 3 个选项卡项的闪亮仪表板。在名为 Results 的第三个中,显示了一个 rmd 文件。问题是,一旦我打开此选项卡并显示 rmd 报告,其他选项卡中的正文就被破坏了,它就像第二个仪表板一样包含在主体内。知道为什么会这样吗?

ex.rmd 文件

---
title: "An example Knitr/R Markdown document"
output: html_document
---


{r chunk_name, include=FALSE}
x <- rnorm(100)
y <- 2*x + rnorm(100)
cor(x, y)

和 app.r 文件

library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
library(shinyjs)
library(knitr)
dbHeader <- dashboardHeaderPlus(

)

shinyApp(
  ui = dashboardPagePlus(
    header = dbHeader,
    sidebar = dashboardSidebar(
                               sidebarMenu(id = "sidebar", # id important for updateTabItems
                                           menuItem("Welcome", tabName = "well", icon = icon("house")),
                                           menuItem("Consent", tabName = "conse", icon = icon("line-chart")),
                                           menuItem("Results", tabName = "res", icon = icon("line-chart"))
                               )           ),
    body = dashboardBody(
      
      useShinyjs(),
      tags$script(HTML("$('body').addClass('fixed');")),
      
      tags$head(tags$style(".skin-blue .main-header .logo { padding: 0px;}")),
      tabItems(
        tabItem("well",
                fluidRow(
                  column(5,),
                  column(6,
                         actionButton("button", "Get started",style='padding:4px; font-size:140%')))),
        tabItem("conse",
                fluidRow(column(3,h3("Concent"))),
                fluidRow(column(3,h5(strong("Purpose of the research")))),
                fluidRow(column(12,"Your practice is being invited to participate in a study which aims to explore the relationship of statin prescriptions and all cause mortality in elderly general practice patients")),
                
                
        ),
        tabItem("res",
                tags$hr(),
                fluidRow(
                  column(3,actionButton('spdf', "Save PDF",style='padding:4px; font-size:180%')
                  ),
                  column(6,
                         uiOutput('markdown'))))
      ),
      
      
      
    )
    
  ),
  server<-shinyServer(function(input, output,session) { 
    output$markdown <- renderUI({
      HTML(markdown::markdownToHTML(knit('ex.rmd', quiet = TRUE)))
    })

  }
  )
)

rmd代码添加了属性

max-width: 800px;

要删除它,您可以使用 fragment.only 选项

HTML(markdown::markdownToHTML(knit('exx.rmd', quiet = TRUE), fragment.only=TRUE))

或者,您可以将以下内容添加到您的 ui

tags$head(tags$style(HTML("
                               body {
                                  width: 100% !important;
                                  max-width: 100% !important;
                               }

                               ")))

那么对之前的tab没有影响
