R中的异常处理

问题描述

有没有人在R中有异常处理的示例/教程？官方文件非常简洁。

解决方案

除了Shane的回答指向您的其他StackOverflow讨论，您可以尝试一个代码搜索功能。 Google的代码搜索指出的原始答案已经被停用，但您可以尝试

• Github搜索在 ;


• Ohloh / Blackduck代码搜索例如

只是为了记录，还有尝试但 tryCatch 可能是最好的。我尝试了Google Code Search的快速计算，但是尝试为动词本身提供太多的假阳性 - 但是似乎 tryCatch 被广泛使用。

Does anyone have examples/tutorials of exception handling in R? The official documentation is very terse.

解决方案

Besides Shane's answer pointing you to other StackOverflow discussions, you could try a code search feature. This original answer pointed to Google's Code Search has since been discontinued, but you can try

• Github search as e.g. in this query for tryCatch in language=R;
• Ohloh/Blackduck Code search eg this query for tryCatch in R files
• the Debian code search engine on top of the whole Debian archive

Just for the record, there is also try but tryCatch may be preferable. I tried a quick count at Google Code Search but try gets too many false positives for the verb itself -- yet it seems tryCatch is more widely used.
