R Markdown 与 Shiny Server 更改主机参数 [英] R Markdown with Shiny Server change host parameter

问题描述

我在服务器上运行 RStudio，并创建了一个 RMarkdown (.Rmd) 文件.如果我将它创建为静态 HTML，它工作正常，但如果我希望它是交互式的(通过添加 runtime:shiny)，它就不起作用.

I am running RStudio on a server and I created a RMarkdown (.Rmd) file. It works fine if I create it as a static HTML but it does not work if I want it to be interactive (by adding runtime:shiny).

问题是，当我添加 runtime:shiny 并按下 Run Document 按钮时，应用程序将尝试在 127.0.0.1:xxxx(这里 xxxx 是一个随机端口)打开.为了使其工作，我必须能够将主机参数更改为0.0.0.0".这是 shiny 包中 runApp 函数中的一个选项，但我不知道如何在 RMarkdown 中添加此选项.

The issue is that when I add runtime:shiny and press the Run Document button the application will try to open at 127.0.0.1:xxxx (here xxxx is a random port). In order to make it work I would have to be able to change the host parameter to '0.0.0.0'. This is an option in the runApp function from the shiny package but I don't know how to add this option in RMarkdown.

谁能帮我解决这个问题?

Can anyone help me with this?

谢谢.

推荐答案

来自 rmarkdown 的 ::run 命令调用 shiny::runApp内部.您可以在运行文档之前设置选项shiny.host:

The ::run command from rmarkdown invokes shiny::runApp internally. You can set the option shiny.host before running the document:

options(shiny.host="0.0.0.0")
rmarkdown::run("myfile.Rmd")

您还可以将任意参数传递给 runApp，所以这也应该有效:

You an also pass arbitrary paramters to runApp, so this should work too:

rmarkdown::run("myfile.Rmd", shiny_args=list(host="0.0.0.0"))

这些都不适用于运行文档"按钮；该按钮启动一个新的 R 会话，在其中呈现文档.要在该会话中更改 shiny.host 选项，您需要将该选项添加到您的 .Rprofile.

Neither of these will work with the Run Document button; that button starts a new R session in which to render the document. To change the shiny.host option in that session, you'll need to add the option to your .Rprofile.
