如何在 Shiny 应用程序中显示它？
我用谷歌搜索了一下，找到了这个包裹
https://www.r-project.org/nosvn/pandoc/shinyRGL.html
而且我还看到了renderRglwidget的存在，见例
R shiny and rgl : 3D points disappear when axes displayed
我追求的是相当简单的东西：一个带有一些控件的流畅页面，我将在左侧添加一些控件，在右侧添加可视化效果。
任何人都可以用我现有的 RGL 代码给我一个例子吗？
非常感谢
好吧，下面的代码目前对我来说已经足够好了，可以完成工作。有效，可以在线部署。

由 reprex package (v2.0.1)
于 2022-02-28 创建如何在 Shiny 应用程序中显示它？ 我用谷歌搜索了一下，找到了这个包裹
https://www.r-project.org/nosvn/pandoc/shinyRGL.html
而且我还看到了renderRglwidget的存在，见例
R shiny and rgl : 3D points disappear when axes displayed
我追求的是相当简单的东西：一个带有一些控件的流畅页面，我将在左侧添加一些控件，在右侧添加可视化效果。 任何人都可以用我现有的 RGL 代码给我一个例子吗？
非常感谢
好吧，下面的代码目前对我来说已经足够好了，可以完成工作。有效，可以在线部署。
