Unwrap t.co links with R

Question

I'm looking to unwrap t.co (for Twitter's shortened URL) links using R.

Here's an example of one: http://t.co/Xvb6T3KyHr

Here's the unwrapped URL: http://www.donorschoose.org/project/we-need-technology-in-physical-education/1684466/?utm_source=dc&utm_medium=project&utm_campaign=twitter&rf=twitter-siteshare-2015-09-project-teacher_3103521

There are answers for Python and JS, but as far as I can tell none for R.

Answer 1

You could try

twitteR::decode_short_url("http://t.co/Xvb6T3KyHr") 

or

httr::HEAD("http://t.co/Xvb6T3KyHr")$url

There's also a package called longurl from @hrbrmstr. However, it seems as if it doesn't work with t.co links anymore.
