R 闪亮应用程序-数据表在本地运行时显示，但在发布时不显示

我构建了一个闪亮的应用程序，它依赖于在启动时加载本地存储的CSV文件。当我在电脑上运行闪亮的应用程序时，无论是在RStudio窗口还是谷歌Chrome上，应用程序都会毫无问题地加载和显示数据。即使没有将数据加载到R会话中，情况也是如此。但是，发布应用程序后，主数据表在启动时或点击提交按钮（试图刷新表）后不会显示

当我从使用Shiny的数据表函数切换到使用DT时，这个问题就开始了。我开始使用DT，以便能够将第一列中的名称用作链接。我目前正在开发运行Mavericks的64位Macbook。今天故障排除时刚刚更新了R和RStudio。我也尝试过在运行Windows 8的计算机上发布-数据表仍然不会显示在已发布版本的应用程序中

库（DT）
pinData我能够解决这个问题。我需要将ui.r中的dataTableOutput更改为DT:：dataTableOutput。让它在R和本地浏览器中正确运行真的让我很反感，让我认为这是一个数据加载问题，而显示/输出是错误的。MLavoie，感谢您在提交时清理代码。
