条件的帮助文件有描述

这些功能提供了一个处理机制不寻常的条件，包括错误和警告。

These functions provide a mechanism for handling unusual conditions, including errors and warnings.

有很多处理函数在文件中解释，并附有示例。所以我建议从

There are many handling functions explained in the file, with examples. So I suggest starting with

help(conditions)
## and
example(conditions)

另外， tools :: assertCondition 可能值得看也是它被链接在条件文档的底部。

Additionally, tools::assertCondition might be worth a look too. It is linked at the bottom of the conditions documentation.
