详细信息----------Details----------

The read.xport function reads SAS xport formatted files, augmenting the functionality of the read.xport function provided in the 'foreign' package with additional features borrowed from sasxport.get in Frank Harrell's 'Hmisc' package.  Namely, variables are properly coerced into the types specified by the format field. All standard numeric and string SAS formats are supported automatically, while user-defined formats are supported when the user has included the appropriate format data in the xport file via: <pre>      PROC FORMAT CNTLOUT=format; </pre> The write.xport function writes one or more data sets into a SAS xport formatted file.  Standard R data types, including date and time objects (e.g. Date, and POSIX.t) are stored with proper SAS format types. Handling of object formatting is customizable by providing methods for the function toSAS. This is accomplished by writing a new method for toSAS for the object class of interest. The toSAS method is responsible for converting its argument to either a simple floating point or character variable (the only basic types permitted by the xport format) and adding the appropriate SAS format code in the "SASformat" attribute.
read.xport函数读取SAS的XPORT格式文件，充实借用read.xport弗兰克·哈勒尔的“Hmisc”包的附加功能中的外国包sasxport.get函数提供的功能。也就是说，变量是正确的类型强制转换成指定的格式字段。所有标准的数字和字符串SAS格式支持自动，用户定义的格式时，支持用户数据的XPORT文件中，通过适当的格式：<PRE> PROC FORMAT CNTLOUT的格式; </ pre><X >函数将一个或多个数据集到一个SAS的XPORT格式的文件。标准R的数据类型，包括日期和时间对象（例如write.xport和Date）存储与正确的SAS格式类型。处理对象的格式是可定制的提供的功能POSIX.t的方法。这是通过写一个新的方法toSAS感兴趣的对象类。 toSAS方法负责将其参数转换成一个简单的浮点或字符变量（只允许的XPORT格式的基本类型），并添加相应的SAS toSAS属性的格式代码。

The write.xport function also allows the user to override the operating system type and SAS version information, as well as object creation and modification times.
write.xport功能也允许用户覆盖操作系统的类型和SAS版本信息，以及对象的创建时间和修改时间。
