I work with R programing language. I have a data frame with one column contains url like this:

myUrl <- "https://twitter.com/UserName"

I need to get rid of everything before the last /. The regex pattern seems to be (see this)

[^/]+$

I can't find the correct function to keep UserName. I thought grep was my friend, but it does not work:

[R] grep('[^/]+$', myUrl)
[1] 1

Obviously this is not what I want. No success with other family functions. Can someone please tell me the correct command?

`gsub('/U.*',"\\1", myUrl)` `gsub('.*/',"\\1", myUrl)` The U is the fisrt character of your username – Orhan Yazar Aug 04 '17 at 09:23
