从R中的url路径获取文件名 [英] get filename from url path in R

问题描述

我想从R中的url中提取文件名.现在，我按如下方式进行操作，但也许可以像在python中那样做得短一些.假设路径只是字符串.

I would like to extract filename from url in R. For now I do it as follows, but maybe it can be done shorter like in python. assuming path is just string.

path="http://www.exanple.com/foo/bar/fooXbar.xls"

在R中:

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

在Python中:

path.split("/")[-1:]

也许有一些sub，gsub解决方案?

Maybe some sub, gsub solution?

推荐答案

有一个用于此的功能...

There's a function for that...

basename(path)
[1] "fooXbar.xls"
