部署 R shiny 应用程序后出错（找不到对象）
[英]Error after deploying R shiny app (object not found)
问题描述
我正在开发我的第一个shiny应用程序，在将应用程序发布到 shinyapp.io 服务器时遇到了问题。 该应用程序在我的 R Studio 本地运行良好，但是在部署后并在 web 浏览器中打开时，它在日志中显示一条错误消息： “Warning: Error in unique: object 'df_app_MT' not found”. 但是 'df_app_MT' 已经存在于 .Rdata 中。 我已经浏览了几个帖子，但错误仍然存在。
我已将（ui.R、server.R 和.Rdata）放在应用程序的文件夹中。 还检查了闪亮仪表板，应用程序（状态显示“正在运行”）。 这是我当前的 ui.R 代码和日志详细信息以及屏幕截图。 请帮助我如何解决此问题。
谢谢你，图菲克

我看不出从拆分应用程序切换到单文件应用程序会如何改变任何事情，但该应用程序可能第一次无法在同一工作目录中找到 .RData 文件。 在本地，如果 df_app_MT 恰好在您的工作环境中，这可能会被忽略。
