Fix Objects Saved from R Versions Previous to 1.8
修复从R版本1.8之前保存的对象
译者：生物统计家园网 机器人LoveR
描述----------Description----------
Beginning with R version 1.8.0, the class of an object contains the identification of the package in which the class is defined. The function fixPre1.8 fixes and re-assigns objects missing that information (typically because they were loaded from a file saved with a previous version of R.)
R版本1.8.0开始，对象类包含在定义类的包的识别。函数fixPre1.8修复和再转让对象，因为他们从河的旧版本保存的文件加载缺少的信息（通常）
用法----------Usage----------
fixPre1.8(names, where)
参数----------Arguments----------
参数：names
Character vector of the names of all the objects to be fixed and re-assigned.
字符向量的所有对象的名称固定下来，并重新分配。
参数：where
The environment from which to look for the objects, and for class definitions. Defaults to the top environment of the call to fixPre1.8, the global environment if the function is used interactively.
从中寻找对象，并为类定义的环境。默认的呼叫fixPre1.8，全球环境的交互功能用于顶级的环境。
Details
详情----------Details----------
The named object will be saved where it was found. Its class attribute will be changed to the full form required by R 1.8; otherwise, the contents of the object should be unchanged.
它被发现的地方命名的对象将被保存。它的阶级属性，将改为由R 1.8所需的完整形式，否则，该对象的内容应该是不变的。
Objects will be fixed and re-assigned only if all the following conditions hold:
对象将被固定和重新分配，只有当所有下列条件：
The named object exists.
命名对象存在。
It is from a defined class (not a basic datatype which has no actual class attribute).
它是从定义的类（而不是一个基本数据类型，它有没有实际的阶级属性）。
The object appears to be from an earlier version of R.
对象似乎是从早期版本的河
The class is currently defined.
目前正在定义的类。
The object is consistent with the current class definition.
对象与当前类的定义是一致的。
If any condition except the second fails, a warning message is generated.
如果以外的任何第二个条件失败，会产生一个警告消息。
Note that fixPre1.8 currently fixes only the change in class attributes. In particular, it will not fix binary versions of packages installed with earlier versions of R if these use incompatible features. Such packages must be re-installed from source, which is the wise approach always when major version changes occur in R.
请注意，fixPre1.8目前仅修复类属性的变化。特别是，它不会修复与R的早期版本不兼容的功能，如果使用这些已安装的软件包的二进制版本。这样的包必须从源代码重新安装，这是明智的做法主要版本的变化时，总是出现在R
值----------Value----------
The names of all the objects that were in fact re-assigned.
事实重新分配的所有对象的名称。
