【问题描述】：
编辑：我简化了应用程序并使其所有代码都可重现。 编辑 2：我刚刚发现，当我使用 navBarPage 时，我必须单击 Additional Parameters -> Colour。然后按预期着色。
我正在开发一个闪亮的应用程序，它可以过滤我的基因，然后绘制剩余基因的热图。最近，我发现了 shinyHeatmaply 包。我已经下载了他们的全局、UI 和服务器，当我在自己的计算机上尝试时，它们按预期工作。不幸的是，当我尝试使用 navbarPage 组合我的过滤器应用程序和它们的热图时，最后一个没有正确渲染。
我创建了一个极简示例，将 shinyheatmap 添加到 https://shiny.rstudio.com/gallery/shiny-theme-selector.html 应用程序中 navbarPage 的第二个 tabPanel，但我还是得到了相同的灰色渲染。
Same mistake in a simpler application
用户界面： Navbar 1 属于 shinytheme 应用程序，而 Navbar 2 的内容属于 shinyheatmaply

没有 Data 上传和没有 server 功能，没有人可以重现您的应用程序，也看不到任何热图......唯一的事情我可以推荐安装 ggplot2 的开发版本。
