This is a minimal R client for the flickr API.
Notably it does not currently support uploading photos.
This is a basic example which shows you how to solve a common problem:
flickr::authenticate()
flickr_GET("flickr.photo.search", text = "UseR2016")
Duncan Temple Lang wrote Rflickr (GitHub) in 2011. Unfortunately it only supports the legacy "frob" authentication which has been deprecated by flickr and is no longer functional.
