我目前正在尝试通过shinyproxy与docker结合运行我的r-application -不幸的是没有成功。
通过R-Studio启动应用程序时没有问题。然而，只要我创建Docker映像并尝试调用它，我就会得到错误消息&;function %>% not found"。
我认为包没有正确加载，但我不能说为什么。在我的Docker文件中，我引用了一个"installlibraries . r"文件，其中包含应用程序所需的所有库。我还调整了rProfile文件，以便每个R会话都应该加载所有库。
对于一个类似的应用程序，它不那么广泛(但具有几乎相同的dockerfile以及applications.yml)，通过shinyproxy和docker托管没有任何问题....
哒你可以找到我的Docker文件，我的个人档案。网站，我的申请。和我的installlibraries。
也许有人知道我还能做些什么。如果您需要更多信息，请随时与我联系!: -)
谢谢你并致以最良好的问候
注:我知道很多图书馆都是"封闭的"。在其他的和不必要的加载-我还没有抽出时间排序:D

我找到解决办法了。
我在ui.r文件的开头加载了所有的库——不是通过函数，而是直接加载的。这并没有使代码更好，但它可以工作:D
