在 Shiny 选项卡中使用多个 R Markdown 文件 [英] Use multiple R Markdown files in Shiny tabs

问题描述

我正在构建一个 Shiny 应用程序，我想要多个标签集.到目前为止，我得到的代码给了我:

I am building a Shiny App and I'd like to have multiple tabsets. The code I've got so far gives me that:

shinyUI(navbarPage("OEI Grant",
  tabPanel("Part 1 - Organization",
           tabsetPanel("1.x",
                       tabPanel("1.1"),
                       tabPanel("1.2"),
                       tabPanel("1.3")
                       ))))

我无法弄清楚的部分是如何为每个选项卡(1.1、1.2 等)获取单独的交互式文档(R markdown .Rmd 文件).

The part I cannot figure out is how to get a separate interactive document (R markdown .Rmd file) for each tab (1.1, 1.2, etc.).

我正在寻找与 includeMarkdown() 函数等效的函数，但要寻找本身包含 Shiny Apps 的 R Markdown 文件.

I am looking for the equivalent of the includeMarkdown() function but for R Markdown files that themselves contain Shiny Apps.

例如在 1.1 中，我可能想显示以下简单 .Rmd 文件的输出:

For example in 1.1 I may want to display the output from the following simple .Rmd file:

---
runtime: shiny
---
# Data visualization

Example visualization

```{r read-in-data, echo = FALSE, eval=TRUE, message=TRUE}
library(ggplot2)
data(OrchardSprays) # Use this data                                                                                                                                                                            
head(OrchardSprays)
```

## Histogram

We can also look at this data in an interactive histogram.

```{r histogram, echo = FALSE, eval=TRUE}
shinyAppDir(
    "histogram/",
    options=list(width="100%", height=450)
  )
```

这个 RTutor Shiny App 与我正在尝试做的类似多个选项卡，但从查看它们的代码来看，我认为所有内容都在一个 R markdown 文件中提供，并以某种方式解析为不同的部分.

This RTutor Shiny App is something similar to what I'm trying to do as far as multiple tabs but from looking at their code, I think everything is provided in one R markdown file and somehow parsed into different sections.

R Markdown 文档讨论了 链接多个页面 但我想要内容而不是链接.

R Markdown documentation talks about linking multiple pages but I want the content and not links.

唯一的Tabsets 库中的示例 展示了如何将来自服务器的输出.R 进入不同的标签，但不是单独的 R Markdown 文件.

The only example in the Gallery for Tabsets shows how to put output from server.R into different tabs but not separate R Markdown files.

关于如何做到这一点的任何想法?

Any ideas on how to do this?

推荐答案

作为前面答案中提到的方法的替代方案，您可能想尝试此 repo 中说明的方法 https://github.com/vnijs/shiny-site.这是一个概念证明，您可以在闪亮的应用程序中使用 Knitr 渲染 rmarkdown 文件，而无需应用程序将文件分解成多个部分.它通过使用 Shiny 的 renderUI 功能并在 ShinyServer 环境中评估 rmarkdown 文件来工作.

As an alternative to the approach mentioned in earlier answer you may want to try the approach illustrated in this repo https://github.com/vnijs/shiny-site. This is a proof of concept that you can render rmarkdown files using Knitr within a shiny without app having to break up the file into parts. It works by using Shiny's renderUI functionality and evaluating the rmarkdown file in the shinyServer environment.
