html - 如何减少 Shiny 的交互式 rmarkdown 利润？

Question

当 shiny-server 看到 .Rmd 文件而不是 ui.R 和 server.R 时，有什么方法可以减少右边距和左边距吗？正如您在下面看到的，将近一半的窗口是右边距和左边距。有没有办法修改内部 css 脚本来进行更改，或者是否有更简单的解决方案，通过在 markdown header 中添加 geometry 选项？

这是我在 Rstudio 中创建一个新的 Shiny Rmarkdown 文件时生成的示例代码:

---
title: "Untitled"
author: "Me"
date: "10/13/2015"
output: html_document
runtime: shiny
---

This R Markdown document is made interactive using Shiny. Unlike the more traditional workflow of creating static reports, you can now create documents that allow your readers to change the assumptions underlying your analysis and see the results immediately.

## Inputs and Outputs

You can embed Shiny inputs and outputs in your document. Outputs are automatically updated whenever inputs change.  This demonstrates how a standard R plot can be made interactive by wrapping it in the Shiny `renderPlot` function. The `selectInput` and `sliderInput` functions create the input widgets used to drive the plot.

```{r, echo=FALSE}
inputPanel(
  selectInput("n_breaks", label = "Number of bins:",
              choices = c(10, 20, 35, 50), selected = 20),

  sliderInput("bw_adjust", label = "Bandwidth adjustment:",
              min = 0.2, max = 2, value = 1, step = 0.2)
)

renderPlot({
  hist(faithful$eruptions, probability = TRUE, breaks = as.numeric(input$n_breaks),
       xlab = "Duration (minutes)", main = "Geyser eruption duration")

  dens <- density(faithful$eruptions, adjust = input$bw_adjust)
  lines(dens, col = "blue")
})
```

## Embedded Application

It's also possible to embed an entire Shiny application within an R Markdown document using the `shinyAppDir` function. This example embeds a Shiny application located in another directory:

```{r, echo=FALSE}
shinyAppDir(
  system.file("examples/06_tabsets", package="shiny"),
  options=list(
    width="100%", height=550
  )
)
```

Note the use of the `height` parameter to determine how much vertical space the embedded application should occupy.

You can also use the `shinyApp` function to define an application inline rather then in an external directory.

In all of R code chunks above the `echo = FALSE` attribute is used. This is to prevent the R code within the chunk from rendering in the document alongside the Shiny components.

Answer 1

查看由 Rmd 文件生成的 HTML 后，主要内容似乎位于类为 main-content 的 div 下，并且它有一个 max-width属性(property)。查看rmarkdown源代码，我相信也许会发生这种情况here .尝试添加一个 css 规则，例如 div.main-container { max-width: inherit;
