Question

我有一个使用shinydashboard制作的R Shiny应用程序，但是在使UI填充浏览器窗口时遇到了问题。

这是我的ui.R输出：

#
# This is the user-interface definition of a Shiny web application. You can
# run the application by clicking 'Run App' above.

library(shiny)

#shinyApp(ui = ui, server = server, options = list(height = 1080))

正如您在附件中看到的图片所示，该页面正在Web浏览器中被剪切。我的最终目标是将其扩展到全屏，因为我试图使内部用户可以使用和访问它。如果有人对如何将仪表板页面扩展到完整大小有任何建议，那将是不错的选择。

就尝试自己解决问题而言，我研究了以下方面以将其扩展到全屏显示。

我查看了Shiny.js，但这似乎不是通过CRAN进行的标准存储库或安装
我查看了fillPage功能，但这使它成为HTML，并且上面的代码不是HTML格式
我已经研究了调用“填充页面”功能，但是在Web浏览器的整个页面视图中尚未实现。所调用的命令位于ui.R

我运行您的代码，它全屏显示。这里是我的shinyapp.io account上的应用。

也许您必须检查应用程序版本。这是我的软件包版本。我正在使用R版本3.5.2（2018-12-20）和RStudio 1.1.463。

我还尝试了RStudio中的“在窗口中运行”，它也可以全屏显示。

如何使R Shiny Dashboard填满整个页面？
