Cognitive Services With R

Steph Locke shows how to use the Microsoft Cognitive Services Text Analytics API within R:

We have some different languages and we need to first do language detection before we can analyse the sentiment of our phrases

# Construct a request
response<-POST(cogapi, add_headers(`Ocp-Apim-Subscription-Key`=cogapikey), body=toJSON(mydata))

Now we need to consume our response such that we can add the language code to our existing data.frame. The structure of the response JSON doesn’t play well with others so I use data.table’s nifty rbindlist. It is a **very good* candidate for purrr but I’m not up to speed on that yet.
