我正在开发一个闪亮的应用程序来过滤我的基因，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，用户界面和服务器，当我在自己的计算机上试用它时，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他们的热图时，最后一个不能正确地进行渲染。
我创建了一个极简主义示例，将shinyheatmap添加到https://shiny.rstudio.com/gallery/shiny-theme-selector.html应用中navbarPage的第二个tabPanel，但无论如何我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

提前感谢解决这个问题的英雄。 最好的奖励，丹尼尔。
答案 0 :(得分：0)
问题是条件面板（使用js）和导航栏页面之间存在冲突，由于任何原因均未读取默认参数，因此未启用应启用的自动着色。我只是删除了此条件面板，并始终设置其选项。
