Is it possible to see the syntax error or runtime error line number (highlight also) generated after running the code in R studio?
是否可以在R studio中运行代码后看到语法错误或运行时错误行号(也可以突出显示)?
I searched the options but couldn't find.

There are many ways to debug R code/script. This is only one example.
有很多方法可以调试R代码/脚本。这只是一个例子。
In RStudio, from the Debug drop down menu option On Error, choose Error Inspector for (what I think is) the easiest debug mode for finding the line number of an error/bug. You can also choose Break in Code to show the highlighted line of an R script that contains the error.
在RStudio中,从Debug下拉菜单选项On Error,选择Error Inspector(我认为是)最简单的调试模式,用于查找错误/错误的行号。您还可以选择Break in Code以显示包含错误的R脚本的突出显示行。
When the error occurs, you can click either of the small areas marked Show Traceback and Rerun with Debug. The screen shot below shows the effect of clicking "Show Traceback" (hence it now says "Hide Traceback"). It tells me that the error occurred when R attempted to call sample (the third call). LENGTH had not yet been defined.
发生错误时,您可以单击标记为Show Traceback和Rerun with Debug的小区域中的任何一个。下面的屏幕截图显示了点击“Show Traceback”的效果(因此它现在显示为“Hide Traceback”)。它告诉我当R试图调用sample(第三次调用)时发生错误。 LENGTH尚未确定。
