详情-----Details-----

The condition system provides a mechanism for signaling and handling unusual conditions, including errors and warnings. Conditions are represented as objects that contain information about the condition that occurred, such as a message and the call in which the condition occurred. Currently conditions are S3-style objects, though this may eventually change.
条件系统提供了一种用于发信号和处理异常情况（包括错误和警告）的机制。条件表示为对象，这些对象包含有关发生的条件的信息，例如消息和发生该条件的呼叫。当前条件是S3样式的对象，尽管最终可能会改变。

Conditions are objects inheriting from the abstract class condition. Errors and warnings are objects inheriting from the abstract subclasses error and warning. The class simpleError is the class used by stop and all internal error signals. Similarly, simpleWarning is used by warning, and simpleMessage is used by message. The constructors by the same names take a string describing the condition as argument and an optional call. The functions conditionMessage and conditionCall are generic functions that return the message and call of a condition.
条件是从抽象类condition继承的对象。错误和警告是从抽象子类error和warning继承的对象。类simpleError是stop和所有内部错误信号使用的类。类似地，warning使用simpleWarning，message使用simpleMessage。具有相同名称的构造函数将描述条件的字符串作为参数和可选调用。函数conditionMessage和conditionCall是返回消息和条件调用的通用函数。

The function errorCondition and warningCondition can be used to construct error conditions of a particular class with additional fields specified as the ... argument. warningCondition is analogous for warnings.
函数errorCondition和warningCondition可用于构造具有指定为...参数的附加字段的特定类的错误条件。 warningCondition与警告类似。<
