如何确定R中的当前目录名称？

Question

The only solution I've encountered is to use regular expressions and recursively replace the first directory until you get a word with no slashes.

gsub("/\\w*/","/",gsub("/\\w*/","/",getwd()))

Is there anything slightly more elegant? (and more portable?)

Answer 1

Your example code doesn't work for me, but you're probably looking for either basename or dirname :

> getwd()
[1] "C:/cvswork/data"
> basename(getwd())
[1] "data"
> dirname(getwd())
[1] "C:/cvswork"

Answer 2

如果您不知道基basename （而我也不知道），则可以使用以下代码：

tail(strsplit(getwd(), "/")[[1]], 1)
