R Shiny应用中的布局，包括R Markdown文件
当我在其中使用R Markdown文件时，我正面临着r shiny的问题，如以下照片所示，我以有线布局大小（仅在屏幕中间，仅在屏幕中间）获得最终结果：
附加到您的代码：
library(shiny)
library(shinydashboard)
library(knitr)
ui <-
dashboardPage(
dashboardHeader(title ='Virtual Excursion'),
dashboardSidebar( sliderTextInput(
inputId = "mySliderText",
label = "Story line",
grid = TRUE,
force_edges = TRUE,
choices = c('1','2')
)
),
dashboardBody(
fluidRow(
column(9,
box(
title = "Operations ",
closable = FALSE,
width = 9,
status = "primary",
solidHeader = FALSE,
collapsible = TRUE,
uiOutput("operations")
)
)
),
fluidRow(
column(9,
box(
title = "Challenges",
closable = FALSE,
width = 9,
status = "primary",
solidHeader = FALSE,
collapsible = TRUE,
uiOutput("challenges")
)
)
)
)
)
server <- function(input, output,session){
output$operations <- renderUI({
req(input$mySliderText==1)
HTML(markdown::markdownToHTML(knit('trial1.rmd', quiet = TRUE)))
})
}
shinyApp(ui = ui, server = server)
您能指导我如何解决此问题！
I am facing a problem with the layout in R Shiny when I use the R Markdown file inside it I get the final result in a wired layout size (small and only in the middle of the screen ) as shown in the following photo:
Attached to you the code:
library(shiny)
library(shinydashboard)
library(knitr)
ui <-
dashboardPage(
dashboardHeader(title ='Virtual Excursion'),
dashboardSidebar( sliderTextInput(
inputId = "mySliderText",
label = "Story line",
grid = TRUE,
force_edges = TRUE,
choices = c('1','2')
)
),
dashboardBody(
fluidRow(
column(9,
box(
title = "Operations ",
closable = FALSE,
width = 9,
status = "primary",
solidHeader = FALSE,
collapsible = TRUE,
uiOutput("operations")
)
)
),
fluidRow(
column(9,
box(
title = "Challenges",
closable = FALSE,
width = 9,
status = "primary",
solidHeader = FALSE,
collapsible = TRUE,
uiOutput("challenges")
)
)
)
)
)
server <- function(input, output,session){
output$operations <- renderUI({
req(input$mySliderText==1)
HTML(markdown::markdownToHTML(knit('trial1.rmd', quiet = TRUE)))
})
}
shinyApp(ui = ui, server = server)
Could you please guide me on how to fix this problem!

问题在于，您将在HTML页面中包含一个完整的HTML文件。两页之间的冲突导致显示问题。您需要输出一个不包括标题的HTML片段。将
fragment.only = true添加到您的Markdown Render函数。您还可以在RMD文件中的YAML部分中添加
输出：html_fragment，以便良好的方法。The problem is that you are including an full html file within an html page. The conflicts between the two pages is causing the display problem. You need to output an html fragment which excludes the heading. Add
fragment.only = TRUEto your markdown render function.You can also add
output: html_fragmentin your yaml section inside the rmd file for good measure.
