R调试 - 看不到哪一行生成警告消息（闪亮） [英] R Debugging - Cannot see which line generates warning message (Shiny)

问题描述

有没有办法让Rstudio告诉你哪一行文件生成了一条警告消息？
现在它只是打印消息，我失去了导致问题的原因。

在Rstudio中，此菜单选项被检查：
调试>错误>错误检查器

但它不帮助，可能是因为这些是警告而不是错误？想法？

解决方案

首先打开 选项（warn = 1） $ b - 通过-r-script-as-r-script-as-they-happen>显示警告 $ b然后，您可以通过点击Source或Source with Echo按钮来运行它（见下图）。当执行错误/警告的任何行时，您可以看到错误/警告消息。

Is there a way to make Rstudio tell you which line of which sourcefile generated a warning message? Right now it just prints the message and I am lost as to what is causing the issue.

In Rstudio, this menu option is checked: Debug > Error > Error Inspector

But it doesnt' help, probably because these are warnings and not errors? Ideas?

解决方案

First turn on displaying warnings using the command options(warn=1) Then, you could run it by clicking on the "Source" or "Source with Echo" button (see image below). You can see the error/warning messages when any line with errors/warnings is executed.
