闪亮的值 [[3L]](cond) 错误但在本地运行

Question

我正在尝试部署一个在我的本地计算机上完美运行的应用程序。但是闪亮日志中的错误消息对我一点帮助都没有。有什么办法可以追踪到我至少知道它发生在哪里？然后我至少可以弄清楚为什么会这样..

闪亮的日志：

该应用程序由 global.R、ui.R 和 server.R 组成，总共包含大约 1300 行代码。同时，我试图注释掉相当多的代码块，但我没有更进一步。

Answer 1

由于错误总是在加载停用词后立即发生（我一开始并没有意识到，这也是代码的结尾），我稍微重新安排了包加载，因为然后就可以了。这很奇怪，因为我没有更改与此相关的任何内容，但是，它现在正在运行。现在的顺序是这样的：

library(tm)
library(tmap)
library(tidytext)
library(stopwords)
library(wordcloud)
