描述----------Description----------
Given two R output files, compute differences ignoring headers, footers and some other differences.
鉴于两个R输出文件，计算差异，忽略页眉，页脚和其他一些差异。
用法----------Usage----------
Rdiff(from, to, useDiff = FALSE, forEx = FALSE, nullPointers = TRUE,
Log = FALSE)
参数----------Arguments----------
参数：from, to
filepaths to be compared
相比，文件路径
参数：useDiff
should diff always be used to compare results?
diff总是被用来比较结果呢？
参数：forEx
logical: extra pruning for "-Ex.Rout" files to exclude the header.
逻辑：额外的修剪-Ex.Rout文件，排除头。
参数：nullPointers
logical: should the displayed addresses of pointers be set to 0x00000000 before comparison?
逻辑：指针显示的地址之前设置比较0x00000000？
参数：Log
logical: should the returned value include a log of differences found?
逻辑：返回值应该包括日志中存在的差异呢？

详情----------Details----------
The R startup banner and any timing information from R CMD BATCH are removed from both files, together with lines about loading packages. UTF-8 fancy quotes (see sQuote) and on Windows, Windows' so-called "smart quotes" are mapped to a simple quote. Addresses of environments, compiled bytecode and other exotic types expressed as hex addresses (e.g. <environment: 0x12345678>) are mapped to 0x00000000. The files are then compared line-by-line. If there are the same number of lines and useDiff is false, a simple diff-like display of differences is printed, otherwise diff -bw is called on the edited files.
在R启动旗帜，从R CMD BATCH任何定时信息将被删除这两个文件，连同有关装载包的线条。 utf-8花式引号（见sQuote）和Windows上，Windows的所谓的“智能引号被映射到一个简单的报价。环境，编译的字节码和其他外来类型的地址表示为十六进制地址（例如<environment: 0x12345678>）映射到0x00000000。这些文件，然后比较行线。如果有相同数量的线条和useDiff是假的，一个简单的diff样的差异显示，打印，否则diff -bw被称为编辑的文件。
As from R 2.14.0 this can compare uncompressed PDF files, ignoring differences in creation and modification dates.
从R 2.14.0可以比较未压缩的PDF文件，忽略创建和修改日期的差异。
值----------Value----------
If Log is true, a list with components status (see below) and out, a character vector of descriptions of differences, possibly of zero length.
Log如果是真实的，一个组件列表status（见下文）和out，特征向量的差异说明，可能长度为零。
Otherwise, a status indicator, 0L if and only if no differences were found.
否则，一个状态指示灯，0L当且仅当没有显着差异。
