Were you using jsonlite? Great library that can parse directly from a URL and transform into data.frame depending on JSON representation. I agree it is not clear from the get go which library should be used when you do something outside of base R. You kind of need to be in the known

I think I was, yes. This is 2+ years ago. I haven't gone back because I got there with REST fetches and internalized re-framing of the JSON. I was just amazed how 'crude' it was, and that the dplyer bindings for ElasticSearch were non-functional (for me at least)
