问题描述

如何在R中抛出错误?我有一个函数需要一个数据框和一些列名,并与它们进行填充。如果列不存在,我希望该功能停止,并根据它停止所有功能。



我看过恢复浏览 traceback 但是,他们似乎很接近但不是我正在寻找的。

解决方案

请参阅 help(tryCatch)

后面的另请参见:

所以你可能想要 stop


How does one "throw" an error in R? I have a function that takes a data frame and some column names and does stuff with them. If the columns don't exist, I want the function to stop and to stop all functions depending on it.

I have looked at recover and browse and traceback but, well, they seemed to be close but not what I am looking for.

解决方案

See help(tryCatch):

and later under 'See Also':

so you probably want stop.
